My young children are begging for a heater. Although I am used to swimming in the cool ocean waters of Long Island, I have to agree that it's not fun swimming in our cold pool. In June the temperature is starts around 65 degrees and gets close to 68 degrees by the end of the month. By mid-summer, we are lucky to get above 76 degrees. We start using the pool in early June and stop using the pool about two weeks after Labor Day.
When we moved in four years ago, there was an existing 400k btu Hayward heater. I ripped it out because I feared it would cost too much to run, and because it occasionally failed to ignite. Now I wish that I had not sold it on Craigslist.
- In-ground, rectangular, 20'x40' concrete pool in the western Philadelphia suburbs. Picture of shallow end attached.
- According to the original plans from 1971, the shallow end is 3.0' and the deep end is 9.5 feet.
- A a recent refill consumed 33,000 gallons.
- There is an existing 2" natural gas line from the basement meter to the pool pump area.
- The electrical supply is poor, two 20 amp, 220vac circuits, one dedicated to the 2HP Challenger pump, and the second currently unused.
- We installed an automatic cover primarily for safety and easier winterizing. The vinyl cover helps with heat retention and noticeably reduces chemical consumption.
I'm turning to the experienced members of this forum for a purchase recommendation. Please recommend a brand and model series for a natural gas heater that can be used to initially raise the water temperature in June and re-heat on demand during June-September. My children are very young, so they require adult supervision to swim. As such, we tend to use the pool mostly on weekends and during the weekday evenings during warm spells.
