Upgrade Heating and Cooling Equipment

A programmable thermostat is a thermostat which is designed to adjust the temperature according to a series of programmed settings that take effect at different times of the day. Programmable thermostats are also known as setback thermostats or clock thermostats.

A smart thermostat is a thermostat that can be controlled with a phone, tablet, smart speaker, or other internet-connected device. Smart thermostats typically allow you to schedule your desired temperature settings, and you can also incorporate them into home automation systems.

Properly using a programmable thermostat in your home is one of the easiest ways you can save energy and money. Keep in mind as you are replacing that your old thermostat is likely to contain mercury, which can be harmful to the environment when not properly disposed. For Information on where to properly dispose of old thermostats near you, visit: Thermostat Recycling Corporation.

Many Smart Thermostats will automatically adjust the settings based on your family’s schedule (including when you are asleep or away) for significant savings all year long. If your Smart Thermostat does not have an E-Learning function, program these settings via an app provided by the manufacturer. These energy efficient thermostats are easy to set up and can save you five to 10% on your heating bills.

A centrally-ducted heat pump operates using the same type of duct system as a central air conditioner or furnace but is able to provide heating as well as cooling by using the difference between outdoor and indoor air temperatures to cool and heat your home, while saving you on energy costs. Mixed ducted systems also use ducts to distribute heating and cooling but involve the installation of new ducting dedicated specifically to the heat pump. Mixed ducted systems may be installed along with ductless units. Learn more by visiting MassSave.com/HeatPump

Ductless heat pumps, commonly known as mini-splits, provide dependable heating and cooling and can save up to 30% in energy costs by moving heat rather than working overtime to generate it. In the hot summer months, heat is moved from inside to outside, while in winter the process runs in reverse, extracting energy from outside air and converting it into heat for your home. Learn more by visiting MassSave.com/HeatPump.

For customers who heat their homes with oil or propane, effectively using heat pumps with your existing heating system can reduce your heating costs. By installing an integrated control, the system can automatically switch from heating with your heat pump to your conventional heating system based on a preselected outdoor temperature. This allows for maximum comfort and cost savings throughout the winter months.

Typical air source heat pumps (central or ductless mini-splits) take heat from outside air using a refrigerant. Air to Water heat pumps transfer this heat to a fluid outdoors – typically water or a mix of water and glycol – and transports this fluid into a home to provide space heating through hydronic distribution (e.g., radiant floor, radiator, or baseboard water circulation systems). These systems can also be used in a cooling mode creating chilled fluid and running it through an air coil to distribute air conditioning to a home or business. While the air to water heat pump market is small in the U.S., it is well established in Europe and China, with a global market of about 1.7M units/year*

Ground source (or geothermal) heat pumps operate using the same type of duct system as a central heat pump or furnace. Ground source heat pumps are among the most efficient and comfortable heating and cooling technologies currently available, because they use the earth's natural heat to provide heating, cooling, and often, water heating.

Work with a licensed HVAC contractor to determine if central heat pumps are right for your home. Before installation, consider the following:

Duct sealing: Proper duct sealing can reduce heating and cooling costs by as much as 15%.

Airflow: A measureQuick trained contractor will check that your system has proper refrigerant change and airflow to get the most from your system.

Sizing: Oversized equipment costs more, uses more energy, and can fail to properly dehumidify your home. Your contractor should make sure you have the right system for your space.

If an existing duct system is to be used with a heat pump, the ductwork should be sealed and insulated to an R-value* of eight. If a new duct system is being installed, as much of it as possible should be installed indoors, and not in the attic (most ventilated attics are subject to extreme temperatures). If wall units are the units of choice, it is important to choose the appropriate size. Despite the variable speed nature of modern heat pumps, oversized units may not dehumidify properly, as they will cool the rooms rapidly. All heat pumps should be sized based on a Manual J load calculation**, as oversized systems will cost more, require larger ductwork to function properly, and may not dehumidify effectively.

 

*R-value is a measure of how well a two-dimensional barrier, such as a layer of insulation, a window or a complete wall or ceiling, resists the conductive flow of heat.

**A Manual J load calculation factors in the different characteristics of your home (such as square footage, position of your walls, building materials, etc.) to determine how much heating or cooling capacity your home needs.

Work with a licensed HVAC contractor to determine if mini-split heat pumps are right for your home. Before installation, consider the following:

• Determine the need: mini-split heat pumps are used for different reasons, from heating and cooling a whole house to an individual room. For whole house use, make sure you have enough capacity and that indoor units are placed appropriately to cover all zones. Multi-head, cold climate models are a good option for whole house heating and cooling, and function efficiently down to very low temperatures.
  
  
• Use with your existing heating system: Using mini-split heat pumps in the winter to complement your existing heating system can reduce your overall heating costs without sacrificing comfort. The highest cost savings occur when mini-split heat pumps serve as the primary source of heat for an entire zone or zones currently heated by a baseboard electric or propane heating system. Based on current fuel prices, if your existing heating system is oil or propane fueled, you can still save money by operating the mini-split as the primary source of heat when outdoor temperatures are above 25°Fahrenheit.
  
  
• Proper sizing: To provide optimum performance, have your contractor size the system to meet your needs. A system that is too large wastes energy and a system that is too small will not provide proper comfort.

Installation of integrated controls will vary greatly depending upon the system and devices chosen. It is best to work with your HVAC contractor to have this properly installed.

Work with a licensed HVAC contractor to determine if GHPs are right for your home. Before installation, consider the following:

• Weatherization: Sealing air leaks – along with adding insulation – is one of the most effective ways to reduce your energy bills, improve the efficiency of your heating and cooling systems, and enhance the comfort of your home
• Duct sealing: Proper duct sealing can reduce heating and cooling costs by as much as 15%.
• Airflow: A measureQuick trained contractor will check that your system has proper airflow to get the most from your system.
• Sizing: Oversized equipment costs more, uses more energy, and can fail to properly dehumidify your home. Your contractor should make sure you have the right system for your space.

If an existing duct system is to be used with a GHP (geothermal heat pump), the ductwork should be sealed and insulated to an R-value* of eight. If a new duct system is being installed, as much of it as possible should be installed indoors, and not in the attic (most ventilated attics are subject to extreme temperatures). Despite the variable speed nature of modern heat pumps, oversized units may not dehumidify properly, as they will cool the rooms rapidly. All heat pumps should be sized based on a Manual J load calculation**, as oversized systems will cost more, require larger ductwork to function properly, and may not dehumidify effectively.

Work with a licensed HVAC contractor to determine if Air to Water heat pumps are right for your home. Before installation, consider the following:

• Determine the need: ATW heat pumps have numerous applications with advantages over traditional hydronic systems in new and existing homes, and advantages over forced air systems in new construction. Compared to a typical gas condensing boiler system, ATW heat pumps can offer energy savings up to 47%* with a seasonal Coefficient of Performance (COP) of 1.7 - 3.0. ATW systems also demonstrate superior performance at low outdoor temperatures when compared with traditional air source heat pumps, making them appropriate for use throughout the United States, including cold regions. * Typical condensing boilers are approximately 90-98.5% efficient (measured using AFUE), while ATW heat pumps are at least 170% efficient at 5 degrees F, (measured using COP).
• In addition to energy savings, ATW heat pump systems can provide the following benefits:
  • Since the system heats water, adding a storage tank to the system will provide homeowners with efficient domestic water heating. This eliminates the need for a separate water heater and can save thousands of dollars for a homeowner.
  • All fans are located outside the home, providing quiet operation.
  • Allows a way to provide cooling in homes without running extensive ducts as mini split style options are available.
• Proper sizing: To provide optimum performance, have your contractor size the system to meet your needs. A system that is too large wastes energy and a system that is too small will not provide proper comfort.

Heat pumps operate for 1,200 to 1,500 hours per year. The outdoor condenser should be cleaned every year, preferably in the fall. The indoor blowers (central or wall/cassette units) have filters that should be cleaned regularly. Clean filters every month, one-inch pleated filters three to four- times per year, and media filters twice per year (spring and fall). Check condensate pump and lines for proper operation and replace humidifier pads annually.

Once your mini-split system is installed, set it and forget it! Leaving this system on full-time optimizes your home’s comfort and efficiency. Designed to run continuously, the system will auto-adjust as the room reaches the desired temperature setting.

To maximize your savings and comfort, our savings guide will let you know how to best use your heat pump for heating and cooling your home.

Integrated controls often have a Wi-Fi component to work with your HVAC systems. Of these, many Smart Thermostats offer E-Learning, and will automatically adjust the settings based on your family’s schedule (including when you are asleep or away) for significant savings all year long. The integrated control also uses manual input stats and records to learn, until it learns what setpoints you are comfortable with. If your integrated control does not have a Wi-Fi or E-Learning function, program a schedule using a guide provided by the manufacturer.

Maintain your equipment to prevent future problems and unwanted costs. Keep your cooling and heating system at peak performance by having a contractor do annual pre-season check-ups. Contractors get busy during the heating and cooling seasons. It is best to have the cooling system checked in the spring and the heating system in the fall. To remember, you might plan the check-ups around the time changes in the spring and fall.

Condensing boilers are gas-fired boilers that achieve efficiency by condensing water vapor in exhaust gases and recovering latent heat that would normally be lost up the flue. By doing so, they can achieve efficiency of 90% or higher (when the system is designed and installed as recommended by the manufacturer).  

Condensing boiler technology is designed to maintain temperature in your home just like the cruise control option on your vehicle maintains a constant speed and conserves fuel.  

While conventional boilers only stop or go at full capacity, your condensing boiler can run at 20% of capacity, 100% of capacity, or anywhere in between depending on demand. The ability to modulate is especially efficient when your system features an indirect domestic hot water heater, which will require year-round operation. Learn more information on  the Mass Save blog.

Not only do modern furnaces save energy, they pollute less and boost comfort by producing heat more steadily than older furnaces. Choosing an energy efficient option can make a big difference! While the lowest efficiency allowed by current federal standards is 78%, high efficiency gas furnaces can hit efficiencies of 95% or more.

Save Even More with an Efficient Furnace Fan

Often referred to as a brushless direct current (DC) electric motor or a permanent magnet motor, an electronically commutated motor (ECM) uses a built-in inverter and a magnet rotor to achieve greater efficiency than alternating current (AC) motors. Used in furnace blower fans or hot water circulation pumps, ECMs can more than double the efficiency of non-ECM fans or circulation pumps. Most efficient furnaces today have these fans already built in.

A boiler reset control is a device that automatically controls the boiler water temperature based on the outdoor temperature. The water can be cooler during fall and spring, and hotter during the coldest days of the winter. This improves boiler efficiency along with indoor comfort by setting a better match between boiler output and space heating needs. A boiler distribution system is designed to keep a home warm on the coldest days of the year. Because a boiler seldom operates in design conditions, turning down the boiler water temperature can:

• Improve boiler efficiency by reducing heat temperature needed
• Improve indoor comfort with more consistent or less intense heat coming off radiators
• Reduce standby losses from pipes

A condensing water heater functions similarly to a condensing boiler, trapping heat from exhaust before it escapes. It is highly efficient but will also require venting and drainage. Look for an efficiency rating of at least 95%.

If your gas water heater is nearing its end of life—typically after 10 years—it is time to think about replacing it. Ideally you want to do this before it breaks and leaves you with no hot water, an expensive repair bill, and a headache.

An indirect water heater circulates water through a heat exchanger in your existing boiler. This heated water then flows to an insulated storage tank. When an indirect water heater is used with a highly efficient boiler, the combination may provide one of the least expensive methods of water heating.

A storage water heater preheats water and stores it in a tank. Despite improvements in insulation, storage water heaters are the least efficient option for most people. Look for an ENERGY STAR® certified storage water heater, which will have an EF* of at least 0.67.

*A water heater's energy efficiency is determined by the energy factor (EF), which is based on the amount of hot water produced per unit of fuel consumed over a typical day.

A tankless water heater (also called an on-demand water heater) heats water as it is requested, rather than preheating and storing it. Because of this, tankless water heaters do not have the standby efficiency losses of a storage water heater and never run out of hot water. However, their flow rate is limited, so one tankless water heater may not be able to handle multiple simultaneous uses. Look for an EF* of at least 0.82.

Boilers are typically identified by several factors

1. Distribution: Steam or hot water
2. Fuel Source: Natural gas, oil, propane, wood/pellets, or rarely coal
3. Existing Venting: Chimney or direct vent
4. Number of heating zones

The best replacement option will be based on these factors or proposed changes to the existing installation. High efficiency (>90% AFUE*) gas boilers can be direct vented through a sidewall or roof, if accessible. These should always be two-pipe installations, taking combustion from the outside and delivering combustion gas to the outside. Installing a direct vent heating product without outside combustion air can depressurize the mechanical space and reverse the flue of any existing chimney vented appliances, such as a gas water heater. Any condensing boiler (typically natural gas or propane) will condense moisture from the flue gasses. This must be discharged to a freeze-proof location via a condensate pump. Most codes require neutralizer cartridges to prevent acidic corrosion of cast iron drain and sewer piping as part of the condensate pump installation.

*Annual Fuel Utilization Efficiency (AFUE) is a measure of how efficiently your furnace can utilize its fuel. The more efficient your furnace, the more heat you will get per unit of fuel.

It is best to leave major repairs, installation, and replacement to your trusted home heating professional.

Properly installed outdoor boiler reset controls help your boiler anticipate demand, which prevents the unnecessary combustion of fuel. It is best to install these controls on a north-facing wall and out of direct sunlight to ensure proper function. Refer to manufacturer’s instructions.

Proper installation and maintenance of your condensing water heater can optimize its energy efficiency.

Proper installation depends on many factors. These factors include fuel type, climate, local building code requirements, and safety issues, especially concerning the combustion of gas-fired water heaters. Therefore, it is best to have a qualified heating and plumbing professional install your condensing water heater.

If you are determined to install your water heater yourself, first consult the manufacturer. Manufacturers usually have the necessary installation and instruction manuals. Also, contact your local municipality for information about obtaining a permit, if necessary, and about local water heater installation codes.

Boilers should be professionally serviced every heating season. The boiler should be inspected for signs of corrosion due to condensation, acidic water, and other potential causes, such as failed gaskets or joints due to expansion and contraction. Any condensate drain lines or pumps should be checked and cleaned to prevent leaks, and any condensate neutralizer media should be replaced.

To ensure your heating system is ready to go for fall and winter, start with a professional evaluation. An HVAC specialist will inspect your system to make sure it is in good working order. He or she will also clean your system to ensure it operates efficiently. Making the investment in annual professional maintenance can help prolong the life of your system, helping you ward off large repair bills or system replacement.

In addition to having your system serviced professionally, there are a few things you can do on your own to improve the efficiency and comfort of your home’s heating system. Check out blog for more information.

Check on the outdoor controller annually to clear any debris from the sensor.

Flush your water heater every six months or so. Drain your tank and remove sediment from the bottom of the tank. Check your anode rod regularly as it is an important part of the water heater. Test the pressure release valve annually. If you notice your water heater leaking, it may be caused by a loose drain valve or pressure relief valve. Contact your plumber if the pressure relief valve is leaking. If you leave town, change your water heater to its vacation setting.

Tankless water heaters can be drained and flushed much like a conventional storage water heater. They can also be maintained annually by checking any condensation piping and if needed, a system descaling. Scale build-up in the heat exchanger may result in reduced flow rate. Periodic descaling may be necessary in areas where the water supply is highly mineralized to prevent flow rate reduction.

The best replacement option will be based on these factors or proposed changes to the existing installation. Oil boilers can be power vented, and many offer outside combustion air options for chimney vented installations, which is a valuable upgrade.  

CAUTION: Oil burners operating above 87.5% AFUE* will condense moisture in the chimney, potentially damaging the masonry construction due to acidic condensate reacting with the lime in mortar.  

A storage or separate water heater may be a beneficial add-on to oil systems. However, it is important to exercise caution because these cast iron systems will experience expansion and contraction. During the cooling season, the boiler will remain cool. The boiler will then fire up to create domestic hot water only. This modulation may result in leaks or early corrosion due to condensation on the heat exchanger itself.

Before replacing your water heater, it is important to consider fuel options and cost if you have more than one option available. You may find that you will save more money in the long term if you use fuel alternate to propane.

*A water heater's energy efficiency is determined by the energy factor (EF), which is based on the amount of hot water produced per unit of fuel consumed over a typical day.

Properly installed outdoor boiler reset controls help your condensing boiler anticipate demand, which prevents the unnecessary combustion of fuel. The outdoor reset control signals the boiler water to run slightly cooler in mild temperatures and slightly hotter during the coldest parts of the winter. This allows for maximum boiler efficiency and indoor comfort, all year long.

The best replacement option will be based on these factors or proposed changes to the existing installation. High efficiency (>90% AFUE*) propane boilers can be direct vented through a sidewall or roof, if accessible. These should always be two-pipe installations, taking combustion air from the outside and delivering combustion gas to the outside. Installing a direct vent heating product without outside combustion air can depressurize the mechanical space and reverse the flue of any existing chimney vented appliances, such as a propane water heater. Any condensing boiler (typically natural gas or propane) will condense moisture from the flue gases. This must be discharged to a freeze-proof location via a condensate pump. Most codes require neutralizer cartridges to prevent acidic corrosion of cast iron drain and sewer piping as part of the condensate pump installation.

*Annual Fuel Utilization Efficiency (AFUE) is a measure of how efficiently your furnace can utilize its fuel. The more efficient your furnace, the more heat you will get per unit of fuel.

It is best to leave major repairs, installation, and replacement to your trusted home heating professional.

Proper installation and maintenance of your water heater can optimize its energy efficiency.

Proper installation depends on many factors. These factors include fuel type, climate, local building code requirements, and safety issues, especially concerning the combustion of gas-fired water heaters. Therefore, it is best to have a qualified heating and plumbing professional install your demand water heater.

If you are determined to install your water heater yourself, first consult the manufacturer. Manufacturers usually have the necessary installation and instruction manuals. Also, contact your local municipality for information about obtaining a permit, if necessary, and about local water heater installation codes.

Check on the outdoor controller annually to clear any debris from the sensor.

Because a boiler seldom operates in design conditions, turning down the boiler water temperature can:

• Improve boiler efficiency by reducing heat temperature needed
• Improve indoor comfort with more consistent or less intense heat coming off radiators
• Reduce standby losses from pipes

Boilers should be professionally serviced every heating season. The boiler can be looked over for signs of corrosion due to condensation, acidic water, and other potential causes such as failed gaskets or joints due to expansion and contraction. Any condensate drain lines or pumps should be checked/cleaned to prevent leaks and any condensate neutralizer media can be replaced.

To ensure your heating system is ready to go for fall and winter, start with a professional evaluation. An HVAC specialist will inspect your system to make sure it is in good working order. He or she will also clean your system to ensure it operates efficiently. Making the investment in annual professional maintenance can help prolong the life of your system, helping you ward off large repair bills or system replacement.

In addition to having your system serviced professionally, there are a few things you can do on your own to improve the efficiency and comfort of your home’s heating system. Check out our blog for more information.

Flush your water heater every six months or so. Drain your tank and remove sediment for the bottom of the tank. Check your anode rod regularly, as it is an important part of the water heater. Test the pressure release valve annually. If you notice your water heater leaking, it may be caused by a loose drain valve or pressure relief valve. Contact your plumber if the pressure relief valve is leaking. If you leave town, change your water heater to its vacation setting.

Tankless water heaters can be drained and flushed much like a conventional storage water heater. They can also be maintained annually by checking any condensation piping and conducting a system descaling, if needed. Scale build up in the heat exchanger may result in reduced flow rate. Periodic descaling may be necessary in areas where the water supply is highly mineralized.
