sfaust Posted December 21, 2018 Report Share Posted December 21, 2018 Anyone able to help me figure out where to find the heater on my spa? We have a spa that was left at our house by the previous owner and it's not heating. The manual is for models 'UHS, UHH, UHP, HU1 & PU1'. Pretty sure it's a dream maker from Googling those models. Anyway, I've traced all wires from the control box; one goes to the lights, one to the controls panel, two to sensors, one to the motor... and that's it. I don't see any wires for the heater or anything on the circuit board marked as heater. I also traced the water lines as much as possible inside the cabinet and I don't see a heater anywhere... I'm confused... Any help anyone can offer would be much appreciated. Quote Link to comment Share on other sites More sharing options...
Jwyrick85 Posted December 22, 2018 Report Share Posted December 22, 2018 There are some spas that don't have a heater. Dream maker has a few that fit that bill. These tubs typically use a heat jacket system on the motor, using motor heat to maintain water temp. Some have a "Hot stick" pump discharge union that causes turbulence and friction in the flow of the water causing heat increase. I've seen some that use both systems. In most cases that I've encountered, these systems do well if the spa is indoors or in an area of the country where you don't get harsh winters. They have a really hard time keeping up at temps much lower than freezing as you can only gain maybe a degree per hour with these types of systems. Hope that helps answer some of your questions.

sfaust Posted December 22, 2018 Author Report Share Posted December 22, 2018 hm :/. Well that sounds like maybe what it is, but we are in Colorado in the mountains and the tub is outside... Wonder if that's why it was semi-abandoned. Maybe it couldn't keep up and they just stopped using it. Don't suppose there is a way to add a 'real' heater to it is there? At least without replacing the circuit board and everything? Quote Link to comment Share on other sites More sharing options...
wish2fish Posted December 26, 2018 Report Share Posted December 26, 2018 Is it a friction heated model? I have a dreammaker and it doesn't have a heating element. My manual list those same control models as your mentioned. Quote Link to comment Share on other sites More sharing options...
wish2fish Posted December 27, 2018 Report Share Posted December 27, 2018 is the motor running? Quote Link to comment Share on other sites More sharing options...
