Cloaked

Thanks Spatech & Brulan! Not sure but I am guessing that the Brett Replacement Heater might be in the ballpark of what I need...

I have an oldie but goodie.. Coleman Horizon 228 Sil/m Built 10/29/87 This is a great spa, but it's time to replace the heater assembly and IU am not sure where to turn to. I doubt that I can replace the original heater assembly, so my question is how much of this unit will I have to replace to make it all work again? The pump is still working okay (Hawthorn 1 1/16 hp) and the controller is good (Using 240 hookup). Any help would be appreciated...
