Boilers are a vessel that heats up liquids (usually water) with combustion by burning fuels, generating steam and hot water.
What type of boiler uses two heat exchangers?
Condensing Boilers. This boiler type uses two heat exchangers: One for heating and the other for reheating purposes. The first one is used before the water goes out to the outlets and the other receives the cooled water to heat it again. They use the exhaust gasses’ energy potential for preheating the cooled water in the boiler.
Why is a boiler a tube?
This type is especially common because of its ability for rapid heat transfer. When the thermostat calls for heat, the burner is activated to heat the fluid. The expansion of the heated water results in the transfer of this extra volume into an expansion tank. When radiating the heat, the water cools down and returns to the boiler to be reheated.
What is a natural gas boiler?
Natural Gas Boilers. This boiler uses natural gas for heating purposes. This gas is either supplied from a large tank of propane gas outside the home or natural gas-lines of the town. The temperature of this gas is regulated with the help of a temperature gauge. The thermocouple minimizes fuel usage as well.
