4 · 1. Furnace. A forced-air furnace heats the home by burning fuel—natural gas, propane, or oil—to heat a metal heat exchanger. The heat transfers to the surrounding air, and a fan blows the heated air throughout the home via ducts and vents. Some furnaces use electricity instead of fuel or as a backup source.

Active solar heating systems use solar energy to heat a fluid -- either liquid or air -- and then transfer the solar heat directly to the interior space or to a storage system for later use. If the solar system cannot provide adequate space heating, an auxiliary or back-up system provides the additional heat. Liquid systems are more often used

Hot water systems generally utilise one of two main types of hot water cylinders: vented and unvented. Vented cylinders require a cold water storage tank, often located in a loft, which feeds water into the cylinder by gravity. This system typically incorporates a vent pipe and relies on atmospheric pressure to distribute hot water.
Aquifer thermal energy storage systems in combination with heat pumps are deeply studied [84], [85]. The analysis proposed in [148] considers both heating and cooling demand with a COP of 17.2 in cooling mode and a COP of 5 in heating mode.
