My husband and I bought a house with an inground sports pool a year and a half ago. Only problem is, it's freezing cold! Our yard is shaded most of the day so the solar blanket isn't enough to warm it. We're trying to put in a heater but with the cost of the gas line and the new heater it's a little out of our budget. Should I buy a used heater from someone who's selling a Laars lite that's 6-7 years old ($350) but the guy says it's barely been used. He used it for a hot tub so it's only 125,000 BTU's but according to the charts I've been looking at it may be enough for our small pool 12 x 24 and 5ft deep.
Can anyone offer me some advice?
