Boilers 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 or a tankless water heater 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.
Low mass boilers have a smaller heat exchanger that does not contain a large mass of metal or iron. While short cycling
a boiler (or turning it on and off frequently) is never ideal, a low-mass boiler will respond better than a
higher mass one because it takes less time to heat up. These boilers also have less standby loss when they cool
down, because they do not have the mass to retain a lot of heat while firing.
