Solar Water Heater

A solar water heater is the best solar energy investment a homeowner can make.  With the new 30% federal tax incentive, state and local incentives, and an 50-80% reduction in your home heating bill, a solar water heater can pay for itself in approx. 3-5 years.  From that point, the solar water heater will be heating your water free for the next 25 years.

Solar water heater - the basics

Solar water heaters come in two different styles, active and passive.  An active solar water heater uses pumps to move heated water from the solar collectors to storage tanks.  Passive solar water heating systems don't use pumps and have no moving parts but are generally less efficient.
