Solar hot water heaters have a lot of variations to consider. Finding the right combination of these is a good way to find the best solar hot water system for your home.
Thermosiphon systems have the collector panels and water storage tank fixed to the roof. Pumped, or split systems have the collector panels on the roof which heat the water and pump it down to a storage tank on the ground.
Depending on whether or not you can have collector panels placed in an ideal location, you may need a larger collector area. These collectors can be either flat panels or the more efficient, but pricier evacuated tubes.
For days when the sun isn’t out, you will need to consider a larger storage tank, or look to gas heaters or electric boosters.
