mass boileBoilers can be a big player in the comfort of your family. Both in water temperature, and in saving money.


A usual household has either a hot water tank  for heating water. While these can be very effective, a boiler can be more efficient since it has a greater degree of modulation rates for the combustion system, and is usually designed to outlast other water heating devices.

High mass boilers are very heavy, as the name implies. Their high mass comes from a large heat exchanger,
which contains heavy metal, often cast iron, and large diameter pipes which contain a high water volume. The
heavy mass helps the boilers maintain steady state efficiency. These boilers take longer to heat up when they
are started, so they should not be short-cycled, or turned on and off frequently, as this will lower their efficiency.
