Burning wood produces environmental impacts. These impacts are reduced considerably when done responsibly.
Responsible wood heating should be defended from criticism that it is bad for the environment. In fact it should be promoted on environmental grounds.
When we talk […]

With the advent of multi-head, ductless heat pumps that maintain their efficiency in sub-zero temperatures, New Englanders are using heat pumps for more than just supplemental heat during the “shoulder” months. They’re using them as a primary heat source and moving away from fossil fuels.
This new way of heating […]

During winter months, heating costs make up the bulk of your fuel bills.
Thus it makes sense for your heating system to work as efficiently and as effortlessly as possible, and you can enjoy the warmth it produces without the worry about how rapidly the dial on your energy meter is […]

Geothermal heat pumps (GHPs) use the Earth’s thermal properties, (the energy under our feet) to provide heating and cooling for buildings, along with water heating. It has had more interest by governments, utilities, developers, and users in recent […]

From the point of view of general economy, there is no more efficient way to heat and cool most buildings than with heat pumps. The most efficient heat pumps are geothermal, which move the heat from or to the Earth’s crust, partly because the temperature underground is […]

Until recently, a biomass boiler produced only heat while a solar PV array generated both electricity and Renewable Energy Credits, or RECs. With the advent of thermal RECs in New Hampshire, Massachusetts, and Connecticut, biomass looks even more attractive!
Saves Energy and Increases Efficiency

Have you stopped to notice all of the heat sources in your home? Things like laptop computers, appliances, lights and people all create heat and are a potential source of energy that can provide domestic hot water and can be used to heat spas […]
A multi-zone, Mitsubishi Electric 36,000 BTU heat pump system serves to cool and heat the Meriden, New Hampshire Library. The installed outdoor unit rests on a bracket to keep it above the level where snow can build up. Line-hide enclosure covers the refrigerant, condensate and control lines running up the side of the building.
