I can’t find my post from last week when I said my spa only heated up 2-3 degrees an hour and was told it shouldn’t take that long. It was suggested I post photos to see if it was wired correctly. So here they are. We used a certified electrician.
Yes but this is at a vacation rental where guests check out at 10 am and new guests arrive at 4:00. It would be nice if they had the use of it that night. Sometimes it’s only a 2 nt stay. Others have said theirs takes 8 hours (which is what salesman had told us) , but ours can be twice as long.
It maintains heat fine during normal operation -it’s just on a drain and fill that it seems to heat up very slowly.
That's because you posted it on a different forum. I've been waiting for the pics, but I need to see the wiring connections at the breaker too. You will have to remove the faceplate, there is usually a screw at the bottom. Turn off the main breaker in the house before removing.I can’t find my post from last week when I said my spa only heated up 2-3 degrees an hour and was told it shouldn’t take that long.

That is a 4kw (at 240v) heater. It's printed on the side. You should feel the temperature difference at the return jet. At 120v, it is 1kw. So, unless it's designed for 120v to the heater, which I doubt, there is another issue.called the manufacturer (Caldera by Watkins) and they told me the rule of thumb is 1 degree an hour heating up! I found out ours is a flow through type heater, 60 hertz and 600 watts.
