Hot Water Heating System Problems | eHow

Expansion tanks are installed near the boiler to allow expansion and contraction of the water as it changes temperature, according to Brumbaugh. Problems arise when the tank loses air and the unit becomes waterlogged, prohibiting expansion. Water is then discharged from the boiler's pressure relief valve, as evidenced by high pressure readings.
