Boiler Installation in Langley & Surrey BC | Repair Service

Boiler installation, repair and service should be done by a certified boiler contractor. A boiler is a closed vessel in which fluid (generally water) is heated, however, the fluid does not necessarily boil. The heated fluid exits the boiler by the use of circulation pumps to various heating applications which include water heating, central heating, based-board, cooking, and sanitation. Most hydronic boilers burn natural gas to heat or boil water. Boilers can operate with water temperatures ranging from 90 degrees F  to 200 degrees F. Most boilers are conventional boilers that operate at water temperatures above 140 degrees F.

This high operating temperature prevents combustion gases from condensing on the heat exchanger. If the water in the boiler drops below 140 degrees F it absorbs so much heat that the combustion gases produced by the boiler begin to condense back into a liquid, which is highly corrosive. The corrosive condensate that forms inside the boiler reduces its operational life and can result in damage to the flue as well. To avoid condensation, boiler thermostat monitoring return water temperature should be set to ensure water temperature stays above 140 degrees F.
