Question about Lite On Laars Lite 2 Heaters: 250,000BTU MV Heater

4 Answers

My Lars pool heater is leaking from within the casing.

When I circulate water through my heater, it leaks out of the bottom. Appears that there is an internal leak or crack. This just happened as I opened my pool after a Canadian winter.

Could also be a pin hole in the small copper tube that runs from the top of the heater to the thermostat. This has happened to me a few times. Small hole, but lots of water comes out. Get some 3/8" copper tubing and 2 compression fittings. It is easy to replace this tube. The only pain is that you have to take off the top of the heater to reach the end of the tube.

Don't throw your heater away just yet.

This year I opened the pool and I had the same experience.

The heater manifold cracked due to water freezing inside of it.

The water is leaking from the top and running down to the bottom of your heater, look at your owners manual there should be a diagram illustrating its inside components are.

I wasn't going to pay $1400 US dollars again for a heater.

I took the manifold off and took it to a weld shop, for $65 it was welded perfectly.

I reinstalled the manifold and other components and I'm up and running again

GOOD LUCK!

Was the heater winterized? If not,, you may be right because of possible freezing . The system may have frozen Is there leakge anywhere wlse? If it was winterized and the system was completely drained, You may be just seeing condensation. If its rinning out , yhrn condensation is out of the question and you may have to get a new heater.It's expensive, but you should consider a timer that will keep the water circulating at a no freeze temp. good luck and check for water coming from some other location that might be misleading.

Reddish smoke


Sounds like it possibly may have frozen internally. Ice blockage and water was not circulating thru it, yet the ignitors fired and fired until it overheated and shut down. Possible that the exchangers may have been fried, that is why the funny color of smoke. Once weather is warmer and not frozen, run the pump with heater off and check for leaks. If no leaks in the heater and you can confirm water is circulating thru your system (water returning into pool thru the return lines) turn or fire up the heater and inspect/monitor its operation.

I let my pool heater freeze


Once a Pool / Jacuzzi heater freezes they will haunt you again and again. You fix one leak and weeks or months later another one appears. Sometimes the only damge done is just the manifold gasket. It would be worth HANDS ON repair "estimate" to find out if it is the manifold or the heat exchanger that has failed. If the heat exchanger has failed BUY A NEW ONE.

Circulating pump shutdown piolet lite shut off on boiler


It sounds like you have a circulation problem. The bleed off valve should only open when you have a presure problem (nonexistent on the open system of a pool) or when you have a over herating problem witch will shut down your pilot also. Check your heater by-pass valve. (A valve in an "H" on the inlet and outlet of the heater) This should be 80-90% closed to force water through the heater. If not this the standered; check the baskets, clean the filter and make suree there is enough water to keep the pump primed. I hope this helps, if not send more info on what is going on.Good luck.

Your drain plug within the evap area of the freezer is frozen, turn frig off, let sit for day or two with doors open. Once all ice has melted then take rear freezer evap cover off and pour water into try and make sure it drains, if not then unplug drain. This is usually caused by a defrost heater bad or unit not going into defrost when it's supposed to, may be main board.

Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

Heater leaking water


The manual is on Pentair's site. If you are leaking water at the plastic conections you might be able to tighten them down a little. Don't go crazy they are only plastic. There are orings in there and may need to be replaced
