what size propane tank is needed to use with this heater?
 Reply

Hi, Elizabeth. This unit requires 1-1/4 gallons of propane gas an hour to operate. You will need a large enough tank to run this unit based on how usage.

Turned on heater and got a message to (service system) Does this mean the heater or /and or filter ?
 Reply

A  Answered on 5/9/2019 by Industry Professional

That is an indication low water flow to the heater. Check the skimmer and filter. If it remains on have the system checked by a certified pool professional.
 Reply


A  Answered on 5/9/2019 by Industry Professional

Check your filter pressure. Does filter need to be back washed? Heaters need the correct water flow to work properly.
 Reply


A  Answered on 5/15/2019 by Industry Professional

This is for the Heater but may be caused by low flow

I have a 13x30 freeform 9000 gallon pool and just want to help add a few weeks to my pool season would this heater do the work I need. Or will I need something larger?

Hi, Kyle. This unit can be used to heat your pool, however, a larger unit will run more efficiently.

Can I control this heater from a 7 day time clock? Pool is at a weekend home and I want the ability to have the heater turn on before we arrive. Does it store the desired temp settings when powered off? Does this mean heater needs to be wired 120v vs 240v? Thanks!
 Reply

A  Answered on 5/6/2019 by Industry Professional

Depending on the time clock you have it will do as you expect. You might need to change your time clock to accommodate this unit however. This unit can be wired we either 120V or 240V.
 Reply


A  Answered on 5/6/2019 by Industry Professional

Yes, the heater will only run if the pump is on, So only when the pump runs will the heater work. It can be wired 120 or 240.
 Reply


A  Answered on 5/6/2019 by Industry Professional

You can hook up the 110V control circuit to a timer and that would control when the heater would be on or off

Is this big enough for my above ground pool? Its 24 foot round and 54 inches deep.
 Reply

A  Answered on 7/8/2018 by InyoPools Product Specialist Lennox H.

Hi, Ron. This 125K BTU heater is a little on the small side, however, will heat a 24' above ground pool. You will get about a 1/2 to 3/4 degree temperature increase per hour.

Mastertemp 125K big enough for a 12000 gallon pool.
 Reply

Hi, Rick. Yes, it can. This unit is ideal for smaller bodies of water up to 15,000 gallons.

Hi there, We have been using an old Purex Triton Mini Max 250 to heat our commercial spa (hot tub). It is worn out and we were thinking of replacing it with the 125,000 btu model. The tub is around 1000 gallons. We think the 250 was actually oversized but we are unsure. Will the 125 heat the water fast enough? and to 104 degrees max? Thank you for your time. Leia
 Reply

A  Answered on 9/13/2017 by InyoPools Product Specialist Patrick P.

Hi Leia, for the spa with the dimensions you listed we would suggest the 250,000 BTU model as the 125,000 BTU will be too small and will take too long to bring your spa up to 104.

I'm thinking of purchasing this item, but the 6 foot cord may be too short to reach the box. Can you use an extension cord?
 Reply

A  Answered on 7/4/2017 by InyoPools Product Specialist Alex V.

Richard, The use of an extension cord is not recommended. In your case, I would recommend the version that does not come with a cord so that you can run the length of cord you need.

Would this work on an above ground pool 24' in the mountain, elevation 2,045 feet? How much would it raise the water temp?
 Reply

A  Answered on 3/23/2017 by InyoPools Product Specialist Lennox H.

Hi, Tamrick. This unit can be used but it not ideal to heat a 24' above ground pool. This unit is rated for an elevation level up to 8,000 feet and you can expect a 1/2 degree temperature increase per hour.

what is the difference between copper and nickel heat exchanger,would I even notice the difference?
 Reply

A  Answered on 7/5/2016 by InyoPools Product Specialist Alan M.

For longer heater life look for a cupro nickel heat exchanger and tubing vs the standard copper units. Cupro nickel holds up better in fluctuating pH levels and salt systems.
