Flue insulation

[Tom Bowling]

I have aTaylors 079D drip feed diesel heater.
I would like to know if anybody has tried to insulate the flue to improve performance.

Welcome to the forums!

The flue pipe emits a lot of heat into the cabin. If you insulate it, heating performance will be affected. The heater manual suggests insulating any flue pipe outside the cabin, by winding it with heat resistant cord.

Hi, I have the same heater and I have added some insulation to the flue. Obviously, only to the section outside above deck. It does not improve the performance but is recommended to speed up the up-draft in the flue when you first light the heater. If the combustion gasses cool too much while going up the flue there is a risk of a downdraft which will extinguish the heater. Once the flue is nice and hot there is little benefit of the insulation. (Sorry to pvb as i was still typing when you posted)

Hello and welcome to the forum.

I'd be interested to understand why you think that insulating the flue will improve performance.

I think what I really meant was to improve the draft of the flue when lighting the heater.
I have had occasional down draft problems and was hoping that insulation might help speed the process of heating the flue and achieving full draft ASAP after lighting. i.e. before the methylated spirit runs out.
I agree that a big proportion of heat in the cabin comes from the uninsulated section before it exits.
