Hi, this is my first post, hopefully I've followed the correct procedure to post. If it's in the wrong directory, please let me know.
Here's my problem. I live in Canada and at the end of last season (beginning of winter), I noticed the temperature of the hot tub dropping. It was due for a water change so instead of fixing the problem then, I decided to drain the water and wait until Spring. It's worth mentioning that I had changed the heater 1 or 2 years earlier... and I bought two titanium heaters at the time. Last weekend, I replaced the heater again (just in case), added water and turned it on. At first the hot tub was showing (IC) for ice because of the cold but after a few days it went up to 60 degrees. That's the temperature it's at now and I only gain about 1 degree every 12 hours or so. I removed the filter to rule that out as a possibility. I'm wondering what else could cause the heating issue. Would it be the circuit board? Any help is greatly appreciated before I call a technician to take a look at it. Thank you.
The hot tub brand is InnovaSpa, Urbania model, hooked up to a dedicated 110v outlet.
