    I bought this unit because my Aquahot was having a problem with firing up. I installed this newer version and works great again.

    Motorhome heat was not working through the Aqua Hot system

    Posted by Patti Smith on 18th Nov 2020

    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!!

    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.
