Solar water heater installation costs - chart Installation costs more for homes with complicated plumbing, roofs above two stories, or collectors located far from the storage tank. Solar water heater installation costs depend on the system type, thermal collector and storage tank size, location, site conditions, and tax credits and rebates.

Thermosyphon systems work best in moderate to warm climates and require a roof strong enough to support the weight of a full water tank. Passive thermosyphon systems feature a rooftop tank mounted above a collector panel to store hot water as it rises from the collector. Water in the tanks is heated directly by the sun before flowing into the home's plumbing system. Integral collector-storage (ICS) passive systems, also called batch solar heaters, feature large, black storage tanks built into a collector box.
Passive systems are less efficient than active systems and are susceptible to freeze damage. Passive systems don't use pumps and rely on convection to circulate the water as heated water rises and cold water sinks. Passive solar water heating systems cost $1,000 to $3,700 for the system alone. Drain-back systems prevent freezing by draining the water from the collector into a separate storage vessel when the pump is inactive. Indirect systems are ideal for homes in regions that experience freezing temperatures.Īctive drain-back systems pump distilled water through the collector and use a heat exchanger to transfer heat to the home's potable water supply. Direct systems are susceptible to freeze damage.Īctive indirect systems, also called closed-loop systems, pump an anti-freeze heat-transfer fluid through the collector and a heat exchanger, which transfers the heat to water in a storage tank. Active solar hot water heating system on rooftopĪctive direct systems, also called open-loop systems, pump the household water supply directly through the collector on the roof, where it is heated and circulated back into the home. Most active systems have a backup heating element to provide hot water on cloudy days. Active systems use a pump to circulate liquid from the solar collectors to a storage tank inside the home. passive solar water heater features FeatureĪctive solar hot water system prices are $2,300 to $6,000 for the system alone.
