Solar Water Heating System

After a (very) brief cruise through their website it looks to me like you will need to keep your existing water heater for back up and run the solar system along side it.

I know of only one company that makes a heat exchanger that will fit into any existing water heater tank, sunmaxx solar. The advantages are; your solar storage and domestic hot water are in the same vessel saving lots of space, the controls are very simple, and back up is automatic. Solar thermal is highly scalable, but for domestic hot water keep it as simple as possible.

Another option you could look at would be a passive system which ties right into your existing water heater gas or electric.Benifits no moving parts, no pumps gravity fed. Down side not quite as efficient doen't circulate the water just preheats it into waterheater.

Solar water heating (SWH) or solar hot water (SHW) systems comprise several innovations and many mature renewable energy technologies that have been well established for many years. SWH has been widely used in Greece, Turkey, Israel, Australia, Japan, Austria and China.In a "close-coupled" SWH system the storage tank is horizontally mounted immediately above the solar collectors on the roof. No pumping is required as the hot water naturally rises into the tank through thermosiphon flow. In a "pump-circulated" system the storage tank is ground or floor mounted and is below the level of the collectors; a circulating pump moves water or heat transfer fluid between the tank and the collectors.
