Looking to add a heater this year (2nd year of pool life). Planning on something around 150kBTU natural gas. To be honest, I am a bit overwhelmed by options and choices. I looked through information at http://poolheaterguide.com/gas-pool-heater-reviews/. What I don't fully understand (haven't tried fully yet) is how efficiency will affect cost. Some options I am considering are Hayward universal H150 (82% eff, $1140), Jandi LXi 250 (88%, 1666), Jandy LRZe 175 (83%, $1280). All prices are from bargainpoolsupplies.com.
- With pH in balance, how long should I expect these heaters to last?
Will a larger unit cost excessively more than a smaller able unit (250 vs 150)?
bargainpoolsupplies.com seems to have must lower costs in all categories of products. Any feedback on them?
Being in Chicago, how much should I expect to save between different efficiencies (82-88%)?
I should also add that I am not too good at navigating this site yet. I found several references to extended discussions (especially between gas and heat pump), but couldn't find them.
