Electric resistance water heaters operate very inefficiently. High-efficiency heat pump water heaters reduce heat loss with well-insulated tanks, produce heat up to 60% more efficiently using the refrigerant cycle, and produce cooling and dehumidification that can be beneficial during hot weather. However, critical installation best practices need to be followed to ensure a successful project. Use this checklist to get the significant energy savings benefits possible from a quality installed heat pump water heater.

Nearly half of all heating and cooling systems in U.S. homes are not installed to manufacturer’s instructions and therefore perform below rated capacity and efficiency. In addition, older oil and gas boilers have low efficiency and use natural draft exhaust with the potential to back draft or spill combustion gases. High-efficiency sealed-combustion direct-vent oil and gas boilers have efficiencies exceeding 90% and include ducted exhaust and supply air that cannot backdraft combustion gases. However, critical installation best practices need to be followed to ensure a successful project. Use this checklist to get the significant energy savings, enhanced comfort, and safety benefits possible from a quality installed oil or gas boiler replacement.

Gas water heaters in many homes have low efficiency and use natural draft exhaust with the potential to back draft or spill combustion gases. High-efficiency gas tankless water heaters eliminate heat loss from stored hot water in tank systems, use more efficient burners, have ducted supply and exhaust air that cannot backdraft combustion gases, and can provide an endless supply of hot water. However, critical installation best practices need to be followed to ensure a successful project. Use this checklist to get the significant energy savings and safety benefits possible from a quality installed gas tankless water heater.

Many homes have excessive holes, cracks, and missing air barriers resulting in unwanted heat loss in cold weather, heat gain in hot weather, and infiltration of moisture, dust, pollen, and pests year-round. Air sealing is often one of the most cost-effective measures you can take to improve your home’s performance. However, critical installation best practices need to be followed to ensure a successful project. Use this checklist to get the significant energy savings, enhanced comfort, and health benefits possible from quality installed home air sealing.
