Although it’s not in the news as often as solar electric (PV) systems, solar water heaters are also a great way to save money and go solar.
Solar water heaters use the heat of the sun to preheat water for your water tank. A liquid substance, similar to antifreeze, is pumped up to panels on the roof where it is heated. The heated liquid is then pumped back through though coils in your water heater, heating your water and offsetting some of your electricity or gas use.
On average, installing a solar water heater can reduce your water heating bills by 50%-80%. And, because the sun is free, you’re protected from future fuel shortages and price hikes.
Solar water heaters are also less expensive than PV systems.
Depending on your location and the size of your home, a system can cost from $2,000 to $6,000. Although that price is higher than that of a traditional gas or electric system, you will save significantly more in fuel costs over the life of the system.
