I'm trying to find replacement parts for the control box of a OHECO heating system. This is a type of unit that derives it's heat by passing water through an aluminum coil around the pump motor. It works well and gets the water to 104 + easily, but keeps tripping a reset of some type ion the control box. This system is on a tub I bought second hand and apparently was sold out of a place called Spa Mart of Charlotte NC. Can anyone provide help or info about the OHECO company.
