I need to buy a heater for my pool. Its 15' x 36" I need it to heat quick and when needed. Not so much as to maintain a constant temp day and night. Im looking at a Raypak Versa 130 propane heater. Id like to be able to get my temps from around 75+ in the early morning to around 85+ for swimming later that day. The pool is only around 4000 gallons. I live in eastern Canada so i can get a bit chilly in the evenings.
P.S. Great site full of information... I'll be a regular here now.
