A  Answered on 8/27/2016 by InyoPools Product Specialist Stacey M.

Hello Danny, Depending on how much you run it is going to depend on cost, a lot of people turn there heater off when they aren't using the pool. Run time will determined how much Propane you will use. If you are wanting to have a propane line put in that is a quote needing to be done by a Gas contractor.

Is this the professional series? and how does it compare to the R408A?

A  Answered on 3/17/2016 by InyoPools Product Specialist Lennox H.

Hi Debbie, We do not carry the Professional Series. They're definitely better designed and built units but will heat the pool the same as the Residential units.

?     Asked on 12/9/2014by Ismail

I've currently Zodiac 325 Btu Propane Swimming Pool heater Indoor. Will this replace the current I've have.

A  Answered on 12/9/2014 by InyoPools Product Specialist Brian M.

This would replace it and then some. You would get an extra 81000 BTUs. I would suggest checking with your propane gas company to make sure the line you have would be enough to supply the  greater requirements of the larger BTU heater.

?     Asked on 5/26/2012by Guest

I would like to replace my current heater with this unit. It is supplied with propane but I will have Nat Gas next year. What is the parts cost to convert? Also, this will replace a Ray Pak P-R405A. Is the wiring basically the same?

A  Answered on 5/26/2012 by InyoPools Product Specialist Patrick P.

The Conversion kit for the 406 unit is only available for the milivolt unit and not the electronic ignition unit, you may view the conversion kit here http://www.inyopools.com/pool_parts_raypak_atmospheric_heaters.aspx (last part on the page - $125.99) This link has an explanation on the differences of electronic ignition and milivolt ignition http://www.inyopools.com/poolanswers_heaters.aspx#electonic_millivolt_ignition and if you would like to purchase the entire heater you may do so here http://www.inyopools.com/heaters_rpseries.aspx Yes this would replace the P-R405A and if you went with the electronic ignition version the wiring would be relatively the same, however if you went with the milivolt ignition there would be not wiring involved.
