Preheating using solar
My home is just over 2000 sq ft and located in the southeast. I replaced the a/c 7 years ago with a 12 seer system.
All of my heat and hot water is created by a gas fired boiler mounted outside of my house. It is a rather small apparatus in size, about 3 feet tall and a 18 inches wide. The water it creates is held in a storage tank within my house which does not heat the water...only stores it. There is an air handler which has water coils and the air blows over these water coils giving me forced air heat.
I am looking to replace the current "boiler" for a Noritz, but want to add a way to utilize solar collectors on my roof or behind my home to pre-heat the water. The back of my home faces SSW and I am not in a HOA.
Most systems, it seems, are utilizing radiant heat using this method.
My system as originally designed, has been working great for 12 years. Unfortunately, the people who manufactured my boiler, or whatever you might call it, donÂt make it anymore.
Anyone have any ideas or links to share?
