WebA relatively new type of heat pump for residential systems is the absorption heat pump (AHP), also called a gas-fired heat pump. Absorption heat pumps use heat or thermal energy as their energy source, and can be driven with a wide variety of heat sources such as combustion of natural gas, steam solar-heated water, air or geothermal-heated water, … WebMar 1, 2024 · A failed igniter is often responsible for a gas-powered Dacor oven not heating. The igniter uses electricity to open the valve that allows gas to flow. It then produces an electrical spark to light the gas. Over time, the igniter can become too weak to either open the valve or light the gas. To determine if this is the case, observe the igniter ...
