I currently have a raypak natural gas 2100 model 185 180000 BTU - 26 year old heater. The intake water piping is leaking. The pool has been showing high metals in the opening, and I’m suspicious it may be from this old heater. All pool equipment is indoors in the basement. 20” is the existing equip width, and I can’t fit much wider. Looking at the Hayward H150FD or the Raypak 206A . Hayward is 150000 BTU, Raypak is 199500 BTU. Was leaning to Raypak BUT Another poster was warning against Raypak due to some assembly line problems… heater still begrudgingly works, but takes a while to get it going. And rather than pay to get piping fixed, thinking best to replace it all. Any suggestions, comments?
