BEST ANSWER: I ordered mine at the end of May and still haven't received it. My order is still marked as pending. I answered this a couple weeks ago but for some reason my response was removed. Hope you see this before it's removed again.
will it heat my 19500 gallon pool ?
william s on Apr 27, 2018
BEST ANSWER: Yes, depending on what the outside temperature and wind conditions are when the pool is being heated.
That, of course, depends on where the customer lives and when the pool is in operation.
If it is a pool only used in the summer, the answer is certainly yes.
It heated my 20,000+ galloon pool without difficulty all winter down in Key West.
It takes a long time to initially bring the temperature to the desired point, but running it continuously 24/7 (it cycles on and off to maintain the temperature) thereafter turns out to be reasonably economical.
Much less expensive than using gas, especially LNP.
What is the amperage for this unit?
A shopper on May 5, 2020
BEST ANSWER: Someone needs to read their code book #6 is for 60 amps on residential. #4= 100 amps
I live in pa. Have a pool and spa about 28,000 gal. Want to use for pool and spa during summer to heat pool to 86degrees will the 140btu do the job and heat the spa to 104 degrees?
A shopper on May 26, 2020
BEST ANSWER: I just bought this a couple of weeks ago and installed in Long Island, NY. I have a similar size pool and have had no problem getting the temp to 82 degrees, I haven't tried for 86 but it should work. One thing to be aware of is that it's slow to heat and if the overnight temps are dropping below 50 degrees you cannot run the heater. I tried the first couple of days (temps down to 43 degrees) and the coils froze up. If you want to swim in the spring and fall you may want to consider a heat pump with a defrost option or go with propane, but if you're just looking for when temps are not dropping below 50 overnight then this should work fine.
Is this an electric heat pump? I was told that all heat pumps are electric, but when I read down on this product it talked about gas. I only have electric at my house will this heat pump work?
Natalie L on Jun 24, 2021
BEST ANSWER: it is electric once you set temp that you want pool to be it will come on when your pool pump turns on. mine works great. have a warm pool day
What kind of pad do you set the unit on?
A shopper on Apr 5, 2021
BEST ANSWER: Amazon sells “Plastic Outdoor Equipment Pad” that works awesome.
will it switch out from a hayward heat pump ?
A shopper on Jan 29, 2021
BEST ANSWER: Not quite sure what you mean by "switch out". Can the plumbing be re piped to the new unit? Yes. As it can be re piped with any other pool heater. It is a 220v heat pump so as long as the btus and voltage matches there shouldn't be a problem. Does it have the same measurement as the Hayward heat pump and fit in the same location? I'm not familiar with the size of the hayward unit so if you can find the dimensions and match them up that may help answer that for you. I hope that helps.
does this also cool the pool?
geoffrey d on Feb 27, 2018
BEST ANSWER: This unit is heat only
What gauge wire is needed for Raypak model 8450?
A shopper on Feb 11, 2022

Is this a Commercial Unit?
A shopper on Jan 28, 2021
BEST ANSWER: I am not using it as a commercial unit but it sure heats up my 16x32 deep pool great unit . I would highly recommend it
Does this unit have a low flow cut off ?
A shopper on Apr 28, 2020
BEST ANSWER: Yes the unit will shut itself down if the pool pump turns off or runs out of water. It has a pressure switch on the piping which senses when it loses pressure
Can you provide local installation for zip code 98683?
A shopper on Jan 4, 2019
BEST ANSWER: I'm sorry we do not provide installers in your area.
how to drain the pump ?
A shopper on Mar 8, 2018
BEST ANSWER: There are 2 small drain valves on the PVC union connections outside the pump. I just removed the unions in the winter and let it drain and then wrapped my heat pump in tarp for the winter.

Purchased heat pump for my 18' x 34', 18,000 gallon above ground pool.
Impressively quite. Simple display board operations. I am located in Kentucky. on 4-21-2020, my pool water was sitting at 54 degrees Fahrenheit. 24 hours later my pool was at 75 while running with an outside high temp of 64 degrees and an overnight low of 52. I just got this unit so I'm still learning and I am sure I will be able to supply a much better review in the future.

Great product!! BUT.... read below
I’m giving this 5 stars as it’s such a great price compared to other heat pumps and my 35,000 gal pool is sitting at a perfect 86 degrees. BUT be warned if you’re trying to get it going early in the season - I’m in Long Island NY - if the overnight temp is below 50 degrees the coils will probably freeze and this doesn’t have a defrost function. I didn’t think about this before I bought it and maybe I would have spent the extra for a different unit. At the end of the day though I’m probably not swimming when it’s that cold out so I think this is a great unit for the price

Nice unit. Constructed for performance and durability
The Unit is quit and efficient. My pool is 16K gallon and unit did not struggle to heat the water to the desired temp of 86 degrees.

Pleased with the unit. The LCD panel could be more user friendly and the manual needs to be revisited and have a section titled quick start.

Pleased with the unit. The manufacturer is excellent.

Very very happy
I ordered my heat pump to be placed on my semi in-ground pool, 27 foot round, in Iowa. People said I was crazy for doing a heat pump in Iowa and just run natural gas. I did the math, the up front cost is higher w/a Heat Pump, yes, but it's roughly 1/2 the cost to run. Yes, a gas heater will heat your pool quicker, but that's the only advantage of a gas heater. The longevity of a heat pump will also help defer the long term costs. I just opened my pool a few weeks ago and it took about 3-4 days to get it from 50 degrees up to 80 and the warmer days certainly helped. If I want to maintain that 84 degree heat I have to run my variable speed pump on low overnight and I wake up to 82 degree water, acceptable heat loss in the 50 degree temps overnight. I'm very pleased with myRaypak 8450 unity, it took about an hour to install, dead simple and my electricity bill didn't go up that much $300 in the colder months, negligible in the summer. If I ever do solar panels on my roof this will have been the biggest no brainer in my pool by far.

I would recommend !
Received the Heat Pump in 3 days and it was extremely well packed for shipment. Less than half of an equivalent Heat Pump that Pinch a Penny was trying to sell me.

Warms up me 18K gallons to 88 degrees with absolutely no issues.

With a 20,000+ pool, this may be a little oversized, but it's not always about the motion in the ocean. The heating speed is great and it is relatively quiet. As with any heater, be prepared for a steady stream of condensation from the bottom.

Much quieter than I imagined. It has super simple controls and looks to be made with quality materials. It was 77 degrees outside last weekend in Florida and it heated my 12k gallon pool 1 degree every 40 minutes. We’ll worth the money to extend the season.
