Motorhome heat was not working through the Aqua Hot system
Trouble shot our Aqua Hot system and found this most likely to be the problem, so replaced the old with this new updated version and she works like a charm!!!! It came all the way from England, but got here faster than most things we purchase here in the US at this time!!

Direct replacement for aquahot 450DE control unit
This is a direct replacement for aquahot 450 DE control unit with a webasto burner. Works great, and much better price than what Aquahot wanted for same part.

Spheros Control Unit
I bought this unit after I was told that it was the problem. The new one still didn't work. I bought an aftermarket one and it worked very well. I would like to get my money back.
