How does heater work to keep freeze off pool in winter
Since temps are dropping at night, pool often turns on and water circulates. Last night, pump running, no water circulation. Is this the heater? does it run on electricity or gas? I have inherited this home and pool. Propane tank is empty. do I need it filled to keep pool from freezing in winter?

What state do you live in, what is the brand name and model number of the heater. If you live in a state that gets cold during the winter, call you local pool store and schedule a closing. If the pump is running and water is not circulating, most likely the pump lost prime or your filter needs to be backwashed, or there is some debris in the impeller.

Check the following first:
1) Water level - Have you filled the spa with enough water?
2) Filters - Are the filters blocked, when did you last clean/replace the filter?
3) Is the circulation pump running? If you can hear the pump, can you see/feel the water circulating? If you can't feel the water circulating but you can hear the pump, then you may have an air lock within the pump/heater.
Canadian Spa Co. do offer their own repair service for these spas. Basically they collect the faulty pump unit, repair it and then send it back. Although it isn't cheap and you should check the basics first.
Depending on the design tubs and pools need water to be circulating before heater runs to prevent the heater from burning out. If the circulation pump runs constantly the heater should work any time but a plugged or restricted filter might not let it flow like it needs to.
If the pump only runs in the jet mode then it might be the way it is designed.
Try checking with the manufacturers website for an FAQ section.
Heater is probably always powered?
Water is always circulating thru it, whenever the pump comes on.
So, if there is a demand for heat or there is a "Heat Call", the heater will fire and run until the heat demand is met.
The wiring is not what makes a pump full cycle or circulate. If the spa motor is always on it is either because the pump relay is stuck closed, or the heater isnt keeping temerature therefor requiring the pump to be constantly running. There are also setting on newer style computer boards which determine a pump to be either "jet" or "circulation" pumps.
Also, a spa pump will run fulltime if the water is below 50 degrees F.
you may have a system that uses a small circulating pump that circulates the water thru the heater to keep water temp at proper level (this is usually the case with hot springs spas and is because it is the most cost effective way to maintain constant water heat without using a full size pump or two speed pump just to push water past the heater core. therefore the issue is you have a problem with your jet pump and it has nothing to do with the circulating and heating portion of the spa. you can check to see if there are any reset buttons in or near the equipment as well as open enclosures to make sure everything is clean and dry also make use any contacts on spa skirting are secured propertly
dear friend-there is a couple of things you can do to find the problem,when the engine is cold remove the radiator cap start the engine then look inside to see if the water is circulating,all so look for bubbles in the water,if there is bubbles,you might have a blown head gasket,if there is circulation the water pump is ok,then get the engine up to working temp,then feel both the top and bottom radiator they should be the same temp,if not then the termostat is at fault
