I bought a 5kw for my van. Its a bit clunky to install, and mishaps with too much air inside the fuel lines and it wont run properly, however I found many useful videos and forums online explaining away any problems, which is good because the instructions that come with it are about 4/10 useful.However for the price point Im truly stunned. Once of the best value for money things Ive ever bought and for my Motorhome / Campervan I bought 5kw because I plan to go in the snow and was worried I would be too cold.My god! This thing can put out so much heat I think Im more likely to be too hot than too cold.I might buy the 2kw and put that in instead.
