Hayward Heater: Millivolt vs. Electronic

Postby coldmark » Fri 16 May, 2008 08:38

My dealer sold me a Hayward H200 pool heater with millivolt ignition. He said that's the only ones they sell because you don't have to hook it up to electricity. I have a millivolt heater in my ice shack and it can be a pain to light at times but I do like it.

Will I be happy with the millivolt heater or should I get the electric model?

I would get the electric. With a millivolt model the pilot has to stay lit all the time and can be a real pain in lighting especially when it gets dirty inside the heater.

No you won't be happy with the Hayward millivolt heater.I've worked on almost every brand heater out there and I think its the worst design ever, low profile, very hard to light pilot (the little starter button will be useless in a year). The low voltage means more problems with things like wire ends. I would recommend a electronic ignition heater. They have a digital readout, no guessing what temp its at or where its set and are self diagnostic. Wiring them is very simple and they can be wired into your time clock if you have one

Hayward millivolt or electric

Postby Guest » Sat 24 May, 2008 02:09

I've had a Hayward H200 millivolt system for several years... can't recall when I installed it but it has been at least 5 years. The only problem I've had is that the pilot will occasionally go out in very high winds. However, the igniter has worked fine and I have no problem relighting it when necessary. If you're already wired up electrically, then it is a moot point. Otherwise, the millivolt system will save you the additional cost of wiring.

I have a five-year-old H200 millivolt...it is somewhat difficult to light in the spring. This year it started giving me a new problem that I've yet to diagnose. When I turn the "temperature dial", the heater will not "kick-on" until I am nearly at the highest heat setting, no matter what the water temperature is. I'm hoping that I just need a new burbon (spelled wrong) tube??? Any insight would be greatly appreciated.

I have a similar problem. The pilot is lit and the burners kick on at a low temperature. As soon as I turn the control knob to a higher heat setting, the burners shut off. When I turn the knob back to cool (within the blue zone), the burners kick on again. Any ideas?

You don't have to light a pilot on the electronic ignition heaters. There is a spark that lights the pilot whenever it calls for heat. Do you hear a clicking sound?

Sounds like you two might need the temp probe/sensor replaced. You can do a resistance test with a digital volt meter to see if the probes are sensing the correct temp. Refer to mfg instructions for these specs.
