heater

Hello, new here and total beginner. Just bought a house that came with an inground pool and a heater. Pool company opened pool the only day couldn’t be there so I’m kind of learning about the pool as I go. The Mini max plus heater worked for a few days. Whenever I turned it to pool or spa, all...

Hi, I just installed an Omnilogic and everything is working fine (lights, pumps, schedules, sensors, etc.) but I'm having problems connecting a Hayward HP50HA2 heater pump to it. I added it to the system but I'm unable to remote control it through Omnilogic. Any recommendation will be really...

Hi All. After setting the temperature to the desired level, heater comes on as expected and shuts off when temperature reached. At some point after(I haven’t been able to pinpoint when) the temperature setting reverts to 70-degrees (I believe the default temp). No error messages on the display...

Hey Everyone, I bought my house a couple summers ago and the previous owners left a brand new Raypak 266A pool heater in the pool shed. They never hooked it up to gas or electric but did have the pool plumbing connected (currently in bypass). I'm hoping to get it running this year but I think...

I have a 10yr old (but clean, lightly used) Hayward H400FD heater that began acting up several months ago. Unique from many other IF-related posts I've seen, mine always works perfectly for at least 30 minutes before cutting off, then going through 3 re-ignition attempts, then going to...

Hi all, we just installed a Pentair Ultratemp hybrid heat pump/gas combo heater for our existing inground pool. We have solar so we decided to do the hybrid unit to have the option to use gas or electric plus we live in SoCal so no worries with temps. The pool builder is giving me the option to...

My 3 1/2 year old Pentair Mastertemp 300 natural gas heat exchanger is leaking and causes a loud noise and then shuts off. Apparently my chlorine got too high and caused the copper pipe to corrode and spit blue/black particles in my spillover hot tub during the winter. 20K gallon total that...

Hi Everyone, Looking for a second opinion on an issue we are having with our spa heater. We built our house a couple of years ago and have a large pool and large spa. The spa is around 2500 gallons and is used year round in a cold weather environment in northern Ohio (my wife is nuts). This...

Hopefully somebody can help me. For years the Raypak was the recommended heater. However, now that I'm in need of a replacement the Raypak info on here states that the author will no longer install these heaters due to a manufacturing issue until Raypak fixes the issue. The info was written 9...

Anyone been able to dig up a new version? I seem to have a newer revision and none of the manuals seem to match what is there. It’s a newer square style with different control panel and the setting are different. I’d like to understand what each setting means as no one can tell me.. Hayward is...

I’ve been wondering if the way my pool heater is running is going to cause it to fail early. I have a 400k BTU heater with a 3k gallon pool. This is open year round and set to 80. I have an automatic cover which helps retain heat. The heater comes on for about 5 minutes at a time each hour or...

My heater is leaking due to age/rust and needs replacement but I'm not sure it's a good idea to replace it without addressing other potential problems with my system. I don't know if these things are issues so I'm hoping someone with experience can give me some advice. It's important to me to...

had to resurrect my old TFP account to ask a question on behalf of my sister she has a 30,000 gallon pool in New Jersey. 16'x44' (700 sq ft surface area) Pool gets full sun exposure for most of the day and in fact overheats a bit by the heat of July & August She is looking to get 5-10 degrees...

Hello, I am new to this group and a new pool owner as I just bought a house. My kids were very excited about the hot tub in this new house and sadly it is not operating correctly. The pool has a Pentair MiniMax 400. This is an old model heater. This heater only has one service light and it...

This is the opposite of what everyone else normally asks about how to turn off the delay. I want to create a delay (the same as the pool cleaner delay) before the heater turns on in the intellitouch/screenlogic software. After 2 years of monitoring the heater behavior (Mastertemp 400) as we...

Hey yall! So I've come across an issue with a clients minimax NT. This heater will not ignite for no one. Currently I'm receiving 120v in and out of the hot surface ignitor, I can see it turning RED. The gas valve is receiving 24v at the blue and white wires. Incoming Gas pressure is 8" wc...

I'm hoping someone can give me a bit of advice. This morning I noticed the pool pump didn't come on. I had a look at the control panel. It has power but switching but the pump isn't working. The motorized valves are operating ok and I noticed that there seems no power to the heater. I can't see...

I'll try to keep it short. I have some large areas of staining that I suspected were from copper. My suspicions are driven by the kids hair constantly turning green, as well as a spot test of a vitamin-c tablet having black color reaction with the stains before eventually disappearing. I...

Island spas (2016 model) Symptoms are similar to others listed in other posts, but also a little different. Cycles set to 2. Each runs for 2 hours. Temp set to 101° from cold start up everything seems fine. But, the temperature will overshoot setpoint and ultimately reach 107° before...

I notice a lot of people prefer to have bypass valves plumbed with their heaters so they can bypass the heater when not in use because, they say, it prolongs the life of the heat exchanger and because the pump uses less energy to move the same amount of water without the heater being in the...

Hello, I have my Pentair MasterTemp 400 connected to my Hayward Prologic board via the 2 wire method (18AWG per spec) Fireman Switch to the Heater1 relay on the Prologic I have enabled heater1 in the configuration menu on the ProLogic. I press heater1 and no light illuminates and it says Gas...

Hi everyone, first time posting, but I have an issue with my heater. I have a Pentair Ultratemp 110, bought brand new in early 2021 and I have had some issue lately. It has been having problems heating my pool. For about two weeks it would constantly click on and off incessantly but heat the...

Hi all, Looking for guidance from those with experience with new heater installs as part of a new pool build. The heater has never been able to complete the startup sequence and always results in a fault with 3 LED flashes for IGN SEQ FAILURE. My pool construction was completed early August and...

Hey everyone! New pool owner here. Bought a house with an existing 33k gallon in-ground pool with a Pentair Mastertemp 300 which has been working flawlessly for almost two seasons that I've owned it until I decided to clean it and I messed things up royally. First off, I was installing a wire...

Newish pool owner here, recently went through my first SLAM (clorine dropped due to SWG issue and I didn't catch it). I had been a bit lax in testing and things got away from me. I'm now being more diligent about testing, possibly bordering on OCD behavior. (I live in North Texas and up until...

Hello, My heater is not working. I've replaced the flue temp sensorm I saw another recent thread about this, and I was hoping to get more insight into what to do now. I have noticed there is water on the floor of the heater and on the concrete pad surrounding it. Does this mean I need a new...

Hi, I have a pretty simple setup - 16x32 vinyl liner pool with 2 skimmers/main drains, a variable speed pump (Pentair) with Hayward SWG and HeatPump Pro - HeatPro Heat Pump | Heaters | In Ground Pool Heaters - Hayward Pool Products. I don't really need an automation system as I have full...

Hi there, I am new to the forms but was searching and found a few related posts - so thought I would make one and hopefully get some help. We built our 18x36 pool 2 years ago. We are using hayward and omnilogic products. 6 months after our pool was operational (it is salt water), the heat...

I'm currently servicing a heater for a customer that won't ignite. It will run through 1 cycle of trying to ignite, blower kicks on, gas valve opens, I can smell the gas but no ignition. The service heater LED comes on and then locks out the controls. The AGS light on the back of the control...

I’m thinking about increasing CH to 150, 175, or maybe even 200 to perhaps help the heater (see thread here) and also move CSI closer to 0.0 (even though pool is vinyl) Current tests: FC: 5 CC: 0 PH: 7.5 TA: 90 CH: 110 CYA: 55 (greater than 50, but less than 60 - may bump to 70 some day)...
