Hi, how does this compare to the Jandy JXI 400? This seems to be out of stock at the vendor and I am looking for a replacement.

Jennifer, the Pentair Pool Products MasterTemp Heater 400,000 BTU - NG w/ Electric Ignition Low NOx HD has a comparable BTU output the Jandy JXI 400. The Pentair unit has a slightly higher heater efficiency, and in my opinion, it is a higher quality unit.

We are considering building a new pool and are looking at various options, we live in rural Connecticut. We currently have a salt water pool and use a heat pump. If we were to use a MasterTemp heater, can we still use a salt system as the sanitizer? Does it effect the heater? Thanks Philip Coles

The MasterTemp Heater 400,000 BTU - NG w/ Electric Ignition Low NOx HD - 460805, uses a heavy-duty Cupro-Nickel heat exchanger making it ideal for a saltwater pool.

How long would this heater take to heat a 35,000 Gallon US pool 5 degrees Faranheit

Hi Kirk, so there are a few variables to consider when calculating the heating time in a swimming pool. Here is a guide that we put together called "How Long Does It Take to Heat a Pool?" that should assist with calculating that.
