Boilers

What is a Boiler?

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, baseboards, or hot water coils, 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. The boiler keeps firing, to continuously reheat the returned cool water, and then sends it on its way again throughout your home.

How Does a Boiler Work?

The gas ignites onto a heat exchanger connected to the water pipe carrying the cold water. The heat exchanger takes the gas-generated heat and heats the water, typically to around 140ºF (60ºC). The now-hot water is pushed throughout the home. An electric pump inside or very near the boiler keeps the water flowing through the loop of pipes and radiators.

Boiler Maintenance

As mentioned above, boilers have some wonderful advantages (long life, highly effective, high heat efficiency), but they do need to be maintained on a regular basis to keep these advantages. If you currently have a boiler and it's been awhile since you’ve had maintenance performed on it, or if you’re thinking of installing a boiler, call Chaves HVAC at 978-562-5309.
