SOURCE: Swimming pool cleaning robot doesn't move

Sound like your filter is dirty. Try backwashing if you have a sand filter, or clean your cartridges if that's what you have. A dirty filter will reduce water flow, which in turn affects the Nav.

SOURCE: Pool heater cabinet gets so hot it burned the wires

That condition is from rollout of the burner flames. Check the underside of the heater top for a buildup of debris. Clean it if necessary. You may notice your heat echanger looks like a BBQ pit. If so it is sooted over and needs to be thoughouly cleaned before further use.

If you find this condition, you should also look at your burner tubes once the exchanger is cleaned and the heater is operating. Be sure the flames are nice and blue and 3 or 4 inches tall. If they are not, and especially if they are mostly yellow/orange, you need to do some more inspecting for what is messing up your combustion, which would have led to the soot.

Finally, if none of the previously mentioned conditions exist, consider wind pressure over the top of the heater. In windy areas and in certain installation conditions, you may needa high wind stack to provide positive drafting of exaust gas.

How long does it take to heat a spa pool?

All depends on the amount of water in the spa or pool, and the size of the heater in BTU's. The time for "Heat Rise" will vary and the answer you are looking for can't be provided with amount of info you provided. But if a general rule of thumb - the closest answer: Spa with a gas heater, 1 degree about every 90 - 120 seconds. Electric heater (vary's by KW) on average: cold to hot = 8-13 hours. Swimming pool with gas heater (no suggestion for electric) about 1 degree temp rise every 90 minutes.

Hello I have a tankless water heater I was wondering if you could use it for a swimming pool or hot tub

For a hot tub....meaby, You have to add a pump and a couple thermostatic switches for minimum and maximum temp. For a swimming pool will be easy .Bunch of water will not really need thermostatic switches but you also need a pump and probably a timer so you will not run it more then 20 minute at a time so you will not kill it self destruction !

Pool and Spa Heaters pros and cons

An electric heat pump needs heat available to pump. If it is 30 degrees outside, heating a spa to 102 or so, may be impossible unless the heater has some type of alternative heat source. A properly sized, gas fired heater can take care of a larger range of heating needs. A combination heat pump and natural gas heater, probably with a controller, really makes the issue more difficult, expensive, and would require a lot of study for efficient, cost effective operation. Bottom line: In really mild climates a heat pump might do the job. In cooler climates the gas heater rules. And where a wide range of temperatures and high heat demand is wanted by the customer, a gas heater is the only way to go. A backup heat pump may take years to payout.
