Solar Domestic Hot Water System
In 2007 we installed a solar domestic hot water system. It uses evacuated glass tube collectors mounted on a pipe frame support outside. There are a total of 110 glass tubes. Two 56 Gallon Hot water tanks store the hot water. The system has 4 zones: Tank 1, Tank2, House heat, Garage heat. The two hot water tanks have priority and are brought up to temperature before either heating the house or heating the garage. For some reason taking a shower in solar heated water feels better than taking a shower in petroleum heated water. And we get so much hot water I don't feel guilty taking long hot showers or washing the clothes in hot water.
A custom made controller was used because of the complexity of the system.
