Had a question on heating our attached spa with solar.
I Finally got my pool crystal clear and we now are itching to use it. We currently have no heat source however since the previous owners of the house, or somebody (we just purchased a foreclosure) must have taken the heater as the wires/breaker box etc.. to hook one up are their, just no heater.
Anyways, I decided on going the Solar heat route for our pool, since during the summer it will heat is great plenty, and the winter months we won't worry much about using the pool, but will be using the spa mostly.
I will have 200 Sq Ft. of solar panels to heat my pool which has a surface area of aprox. 375 sq ft.
My question is how warm will it be able to get my spa during the day, if I am only recirculating the spa water through it? ( 6ft. diameter spa aprox 500 gallons)
I am just curious to see if it will be able to get it up to at least 95-100*F so it is at least nice and warm when sitting in it. The water temp with no heat source right now is around 69-70*
I guess I will find out after I have things up and running, and will post an update (I should be installing them up within the next 2 weeks) but am curious to know how warm I can expect solar to get that small amount of water, and if anyone else uses just solar to heat theirs, or has experience with it?
