Heating systems can use a variety of fuel sources, including natural gas, propane, fuel oil, biofuel (such as wood), and electricity. In most cases, burning natural gas in a boiler to heat up water and to circulate warm water in the pipeline systems including radiators is still the most popular and economical way of heating places.

While the heating systems got operated, the pipeline would heat up with the affect of the heated water, this thermal increase causes elongation in the pipelines. The elongated amount must be absorbed by using expansion joint.

Ayvaz produces variety of different expansion joints according to the type of deflection occurred in the heating pipeline systems.
