Solar Hot Water or Water Retainage and Reuse System

Solar Hot Water

Small scale solar space heating systems often use a solar collector that concentrates heat in either a liquid or in the air which is then distributed throughout the home. Active solar heating systems are cost-effective when they are used for a large part of the year, that is, in cold climates with good solar resources. They are most economical when displacing more expensive heating fuels, such as electricity, propane, and oil heat. Certain tax credits are also available for solar home heating technologies.

Water Retainage and Reuse

Rainwater harvesting is the process of intercepting storm-water runoff and putting it to beneficial use. Rainwater is usually collected or harvested from rooftops, concrete patios, driveways and other impervious surfaces. Buildings and landscapes can be designed to maximize the amount of catchment area, thereby increasing rainwater harvesting possibilities. Intercepted water then can be collected, detained, retained and routed for use in evaporative coolers, toilet flushing, pet and car washing, indoor plant watering, pet and livestock watering, and for lawn and garden irrigation.
