Gas Boilers: The Information You Need
A continuous supply of natural gas feeds the gas boiler through the gas main connection in the street. When switch on the boiler, gas is set alight and used to heat water via a heat exchanger. The boiler pumps the heated water to other parts of your house, either to radiators to heat the room, or in the case of conventional or system boilers, to hot water tanks for later use.Get Price
What does boiler turndown ratio mean? | U.S. Boiler Company
2020/12/17 · Boiler turndown ratio defined. Boiler turndown is the ratio between a boiler's maximum and minimum output. Depending on the burner's design, it may have a turndown ratio between 5:1 and 10:1 or even higher. A 5:1 turndown means the boiler's minimum operating load is 20% of the boiler's full capacity ( capacity divided by 5).Get Price
