Most people immediately think of furnaces when opting to heat their homes. However, boilers provide a highly effective heat option, have a long life, can reach high heating efficiencies, and some types require little or no pumping energy. Boilers are an important part of a central heating system. They're a continuous closed loop of pipes carrying heated water (or steam) throughout your home. As the water runs through the pipes, running through radiators, the hot water cools on its path as it gives off its heat, heating your rooms, then returns back to the boiler to be reheated again.

A heat pump is a device that transfers heat from one place to another, from indoors to outdoors or from outdoors to indoors. For homes with no access to natural gas, heat pumps offer an efficient and reliable solution for heating and cooling. In the winter, a heat pump works like a heater, extracting heat energy from outside and transferring it inside.
