Hayward universal h-series heater

15 years ago

Does anyone have any info on this new heater? I have a 20 x 40, saltwater pool. I'm in Kansas, and looking ot the 400k nat. gas unit. Any suggestions?

Thanks,

Too soon to tell on reliability.

When adding remote control via an automation system, you no longer have to set the thermostats up, a plus.

You can also take it out of remote control mode for service, another plus.

It's got a lower profile (read shorter height).

I still prefer the MasterTemp from Pentair and RayPaks with electronic ignition.

You have a couple choices but for the moment, I will only mention one. Putting them in series is what many situation dictate. As long as only one is running at a time, in most situations, it works fine. We need more information about what you have in terms of pool equipment, plumbing sizes, and pool size before we can give you what we think would be reasonable solutions to your needs. Looking forward to your next post; Scott

Hayward Heater and Intelitouch 7

Chances are is that its not the controller. It;s either a problem with the heater control board, or a short in the wire that goes to the controller. Chances are is that its not the controller. If you open the control board (intellitouch) out by the equipment, you will see a connection on the back left side of the control board. It should be marker for HTR. Unplug this and see if anything changes. If nothing changes which I assume it won't, follow that wire into the heater. Remove the connections to the heater and see if anything changes. If it doesnt, its likely a control board. If it does, it's the wire going to the intellitouch.

Help! Buying a Pool Heater

Heating water is different than heating a home. It take 1 BTU to heat 1 pound of water one degree. Given the size of you pool, a 400K BTU Ray Pac will heater your pool fastest. The use of a solar cover will keep the heat there. It will take the same amount of propane whether you have a 100K BTU or a 400K BTU unit. Your existing pool plumbing may not be up to snuff if you have the flexible hoses usually seen on above ground pools. Expect to have to change it to 1.5" pressure rated pipe. This will increase flow and reduce friction losses and reduce how hard the pump works which reduces electrical usage too. Ray Pacs and Rheems are the same heater with different badges, like Pentair and Sta-Rite, Chevy and Buick, etc... Either the Ray Pac or Pentair MasterTemp will provide you years of trouble free service. Scott

We added a Hayward H series heater to our in-ground pool in March. Our pool is 15x32 (3'-5') and we decided to go with the 400k btu unit. We love it so far and it heats the pool up very quickly.

I think it's important regardless. Its more resistant to friction and chemical wear.

Titanium is even tougher but doesn't have the thermal transfer efficiency.

Since you mentioned friction, does it make sense to install a bypass in the piping to isolate it from the system for the majority of the summer, when it is not in use?

That is one of two reasons I do it. The second reason is in case/when the heat exchanger or header does finally wear out and leaks, you can isolate it out of the loop so you can filter and not lose water.

Some pumps also push more water than can accommodated by the heater. The bypass, when cracked open allows some of the water to skip past the heater, keeping pressure down in the heater.
