I have an Eber diesel fired water heater, first time I have had one of these.
The exhaust is an inner stainless semi flexible inner duct with a more flexible outer black aluminium duct cover, there is insulation/lagging between the two. It looks like it a supplied product not a home made assembly. I don't see a silencer anywhere and have read this might be incorporated in this assembly.
Anyone know what temperature the outer cladding should run at with the burner going full on.
I have tried to take readings with an IR gun, but of course it is hard to get to.
The inner portion reading is around 200 deg, which seems too low, however there is only a small amount of the inner duct visible where it is clamped over the heater outlet and I don't think I am getting a proper reading. The outer cover is around 100 degrees at the outer end and about 130 close to the heater, which seems high. This is encased within a plywood box where it passes through the accommodation. Before I get too far into it I would like to know how those temperature readings compare to others.
I don't think there is an exhaust leak as no smell of fumes or any sign of smoke, I suspect the lagging might have got wet at some stage and therefore is conducting heat, of course if that is the case and I keep the heater running it could dry out and the outer temperature should then fall.
Comments please.
