What is a heat exchanger in a boiler? | Viessmann

A boiler works by using hot gas to heat water - and a heat exchanger is what allows this to happen. As the gas is heated, it begins to rise. When it rises, it reaches the heat exchanger and is pushed through the coiled pipe. Cold water is surrounding the pipe and, as

How to Set Hot Water or Steam Heating System …

If we set the boiler upper temperature too high over 200 degrees F. we're at risk of spilling at the pressure temperature relief valve. If we set the boiler upper limit too low, there may be no relief valve problem but under some conditions we may reduce the operating efficiency of the boiler and heating system, thus increasing heating costs.
