hydronic gas boiler heat exchanger

What is a heat exchanger in a boiler? | Viessmann

Condensing gas combi boilers used to have two heat exchangers, as it's thought that this was more efficient. To begin with, the water was heated in the primary exchanger. As hot waste gases were produced, the water that returned from its circuit around the radiators was pushed into the secondary heat exchanger, which only used waste gas to heat the water.

Troubleshooting a Gas-Fired Hot Water Boiler

Modern boiler systems for home heating are hydronic systems, in which the boiler heats water for circulation throughout the house. They are closely related to steam boiler systems, but rather than circulating actual steam, hydronic systems have pipes carrying the hot water that radiates heat through either steel radiators or baseboard convectors (sometimes called "fin-tubes").

How Does a Gas Boiler Heat Exchanger Work? | Gas Boilers

This is possible due to the fact fuel gases are discharged at temperatures above 60°C. The cooling requires the use of a special gas boiler heat exchanger – a stainless steel one, as the steel won't corrode, being in contact with the condensed gases. In a conventional model, the fuel is burned and hot gases that are produced are passed through a heat exchanger. This is where much of the heat is transferred to water, raising the liquid's temperature.

What If My Furnace Heat Exchanger Is Bad?

The heat exchanger must have an air (and gas) tight seal to separate the gasses in the flue products inside the heat exchanger from the breathing air passing over the outside surface. This is because the flue gasses can be poisonous – such as deadly carbon monoxide – and contamination of the breathing air by these gasses pose a health risk and can be fatal.
