Our old heater (purchased with the house) obviously hasn't been used in a very long time. The spa portion of our pool has a bunch of dirt in it, if that's any indication. Are large gas heater something we should be looking to refurbish if we want to eventually get the spa working again, or if there is visible rust around the burners (the front panel was left off for years, we'd guess), should we just cut it out of the system and purchase anew?
truth be told, we'd probably be better off with a solar system where we're located.
thanks for any thoughts!
