2020-6-28 · The electric boiler functions much like the furnace, except instead of pushing hot air through a vent system, the heat generated through electrical resistance is used to heat water, hence the term "boiler". This heated water is then pumped through pipes to radiators in each room, where the heat 'radiates' out into the room. Baseboard

2020-6-24 · Figure 1 – A fire-tube shell boiler. These conventions arise from a practical engineering reality. It's about the water vapour produced during combustion. In one of natures most beautiful symmetries combustion produces water vapour. Condensing this water vapour releases a lot of energy. The high heating value includes this energy.

2020-6-28 · Most of the heating furnaces burn fuel and release hot combustion gases. The hot combustion gases heat the incoming cold air and go out through the chimney. In older furnaces, all the heat in the fuel is not released or not transferred to the cold air (or water, in the case of heat registers and water heaters), and therefore is lost through the
