A DIY solar heating system refers to a homemade setup that uses solar energy to heat homes, water, or other spaces. It typically involves installing solar panels or collectors, storage tanks, and a heat transfer system.
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.
Unlike a solar photovoltaic cell array, which is designed to produce electricity, a solar heating system is designed simply to produce heat. A well-designed solar heating system will provide approximately 55% of your annual domestic hot water requirement.
Cold water is pumped up to the solar panel, it heats up and is transferred to a storage tank. A pump pushes cold water from the storage tank through pipes in the solar panel. The water is heated by heat energy from the Sun and returns to the tank. In some systems, a conventional boiler may be used to increase the temperature of the water.
Solar thermal energy systems use two types of heating technology: Passive: Passive solar heating doesn't use an actual heating system. Instead, this type of heating relies on efficiency upgrades such as insulated blinds and drapes and sun-facing windows to warm your home naturally. The additional insulation seals in heat and reduces heat loss.
