I bought this 24v Diesel heater to replace a Mikuni heater on my barge for which parts are no longer sadly being made. I just finished installing it today, had to obtain various parts and adaptors to fit it to the existing exhaust pipework and fuel lines. It is working well and at present I am very happy that i did not have to pay out about ten times the price for the German equivalent. If anybody is interested I used a motorbike exhaust adapter to link from the existing larger exhaust pipe, found on Amazon I think the heater is good value for money. The English manual is somewhat indecipherable but not a show stopper. I have bought a programmable rheostat, also from Amazon to mimic the button pressing of control so I can hook it up to a room thermostat. Not tried yet but I cannot see why it will not work. Did find that one of the plastic caps on the fuel pump was melted on. Does not seem to have caused a problem. Silencer is not fully sealed so no good for internal use. Happy man!
