NH Heat Pump Contractor

A heat pump is a device that moves heat from one place to another where heat is needed. An air source heat pump employs the same basic heating & cooling refrigeration cycle as an air conditioner or a refrigerator. A heat pump uses a reversing valve to control the transfer of heat which allows the homeowner to both heat and air condition their home with a single heat pump heating system.

Heat Pumps

Tankless Water Heaters

Tankless water heaters provide hot water only when hot water is needed, which saves money on your energy bill. Tankless water heaters also provide an endless supply of hot water which translates to a more comfortable water temperature in a shower for every individual in your home. Tankless water heaters are also significantly smaller than a traditional hot water tank.


Hybrid Water Heaters

A heat pump is a device that moves heat from one place to another; it works much like an air conditioner or a refrigerator. While a refrigerator moves heat from your fridge to your kitchen, a heat pump water heater (HPWH) transfers heat from your home into the hot water tank. HPWHs' will also act as a dehumidifier and will dehumidify your basement.
