Hayward has manuals for each type heater, gas and electric.
Hayward also has contact page, and can probably recommend correct change-over product.

You want to switch from propane to heat-pump type.

There are likely 3 areas of difference. Read each manual and generally look for 1) unit size and capability to match spa 2) pipe connections and sizes 3) Electrical requirement

From electrical standpoint, You need GFCI-protected line from circuit breaker box, or GFCI (arc-fault) breaker. This will prevent electrocution risk around spa.

Wire sizes are based on volts and watt-rating of heater.
Each electrical device has rating plate showing volts and watts.
3500 watts divided by 240 volts = 14.5 amps so install double-pole 20 amp breaker and use 12 gauge wire.
1500 watts divided by 120 volts = 12.5 amps so install sinle-pole 20 amp breaker and 12 gauge wire.

SOURCE: pool heater wont fire up

Its just after 1 am here as well, Ontario Canada. Yes, you have to remove the front lower panel by raising it then pulling out at the bottom. Then compare the valve you have with the 2 in the picture on pg 5. If it is easier, you can have your husband call me while doing this and I can talk him through it. My contact information is located on the main page of my company website

SOURCE: I have a Raypak pool heater the pilot will lite but the unit will

My Rapak gas pool heater burner will not ignite. I changed the flame sensor and then the main gas valve (on a recommendation of a heating contracter) and after spending almost $300 on parts, I may have not needed, it still will not ignite. The water temp has been around 80 using the solar cover but now with the air temp in the 50's at night and only in the 70's in the day the water is a brisk 70 degrees. We would like run the heater now, so we can use the pool for a bit longer this fall.
Any ideas? Some people told me there is a valve that senses the proper amount of water is flowing around the boiler so it doesn't burn up, is this possiblely the problem that the valve is not opening?

SOURCE: I have a Raypak model 153 pool heater. The heater

For some reason your heater is not recognising the flame when it goes on. The biggest reason for this will be small spider webs in the burner orfaces. These are on the main gas manifold where it connects to the burners. You can get a small wire and bend it to go in these orfaces but the first time you do this it will probally be easer to pull the tray and remove the orfaces from the gas line. Good luck, I hope this helps.

SOURCE: My raypak versa spa heater was making a loud sound

Part one - The 'whoosh' or 'boom' at ignition. If those sounds describe your start up your jet(s) are clogged along the gas manifold. Follow the pipe out of the gas valve down to where the gas is shot into the heater. Those bronze ports have a small opening and spiders like to nest inside this area. Turn them out of the manifold and inspect them. You should find those closest to the ignitor are clogged causing the delay and then boom of ignition.

Part 2 - Have this happen enough and the roll out switch / fused link along the bottom of the heaters service panel will open up and disable the heater. It will look like a black rubber tube about 1/4 diameter by about 2 inches long -OR- a white ceramic block about the diameter of a quarter; either will have 2 wires to it and it will be 'close' to the manifold and jets you need to clean out. If you have a way to read resistance across this switch remove the wires from it and check it. If it is open it will need to be replaced.

My hyward H400ID won't ignite green light comes on for few seconds and then goes off. Need help

There are many questions needing answered. Is the fan coming on, if not it could be the fan proving switch. If the fan is coming on but the heater does not light there should be a code on the heater. I added a link to the manual for this heater.

Im a new pool owner and I have a Hayward H400ID heater, It was working great just a couple of days ago and now it will not turn on. I get a system normal light... but when I switch from off to spa/pool...

Many things without more info, but if your new at this let's go with simple. Make sure your baskets are clean and your filter is clean. Without proper water flow the heater would overheat and boil the water inside. Because of this it has safty switches to stop it from running when things get dirty. Good luck and let me know how you do.

How do you set a spa heater to heat the water over 104 degrees?

Sorry set by law and a ery good one to boot. Even if you are the one to reset the manufacture would still assume liability. Heater and thermostat manfacture would both be liable for death or stroke and they try their best to avoide this. So sorry no they have done their best to avoide someone getting hurt or dead.
