hi i've been told that new heat exchangers are of varying quality - where are the best ones from??!! cheers
I had some just kampers ones, got em cheap of fleabay. Work well in my view with all the pipes sealed and flaps working, totem gets really hot!
if you can get decent original ones you'll notice a difference as there are more fins inside, that said i have originals with the odd bad seal here and there and it's red hot in the cab so a fully sealed set of repros would be ok i guess.
I've repro ones because I changed my system from US to Europe. They are not as good on the heat sidw of things until they get hot but I found the through flow is better over the originals. And when you fit new ones take it for a massive 50 mile drive to burn off the stench of the paint. Ruddy awful smell.
We have Ernst repro ones fitted and they are fine. Loads of heat but ten we had virtually no heat before so not hard to improve to
