Looking to purchase a new propane pool/spa heater for an in ground pool. I live in Florida where the sun pretty much heats the pool, so I would use it for the spa. I think I'm between the Pentair Master Temp 250 and the Hayward H250. Wondered if anyone had an opinion on these two with respect to durability and performance, or if there is another brand/model that is even better than these two. Probably looking to spend around $2000 at most. Thank you.
