I have roughly a 20000 gallon in-ground pool, will this unit be sufficient for that?

A  Answered on 3/10/2019 by InyoPools Product Specialist Lennox H.

Hi, Kevin. Unfortunately, (1) one unit will not be sufficient for a 20,000 gallon pool. The E3T Electric Digital 27kW Pool/Spa Heater - 17124  would be the unit and size I will recommend for a pool your size pool when it comes to using an element style heater.

What the temperature range of this unit?

A  Answered on 4/29/2019 by Industry Professional

The mechanical T-Stat that is in this unit has a max range setting of 107*, however, if it is tied in with a standard control system it will be a 104* max temp.

I’m using it for a pond with fish. What is the minimum temperature? Will it keep it at say 70 or 75 degrees?

Hello, Yes, this will be a good heater for your size pool.

Will it easily heat a 10,0000 gallon pool?

A  Answered on 5/4/2019 by InyoPools Product Specialist Lennox H.

Hi, Tina. This unit is too small to heat a 10,000 gallon pool efficiently.
