Frequently Asked Questions

There are many types of solar water heating systems, but the drainback is the most efficient indirect system on the market; it prevents from freezing, and overheating.

A typical solar storage tank is larger than a conventional heater, because you can only harvest the sun during daylight hours. So by upsizing the storage tank, you can store the collected heat for night and early morning use. Our standard size for a standard 3 bedroom home is 80 gallons. We do have 120 gals available if you have a larger home and want to harvest as much of the sun as you can!

Yes, your contractor should give you a complete price; equipment and installation. A site visit is usually required to verify roof space and pipe runs. The entire pipe run to the collector on the roof from the solar storage tank is insulated copper pipe. The ideal location for the solar collector(s) is on the south facing roof with little to no shading from 8-4 if possible. 

A drainback system uses a controller with temperature sensors to monitor the performance of the solar hot water system. When the tank reaches a pre-set temperature limit, the pump turns off and the heat transfer fluid (usually water) drains out of the collector into the drainback reservoir. By removing the solar fluid from the collector, there is no danger of overheating.
