Two cunning plans..............

[Snadger]

First cunning plan is to fill a metal 5 gallon jerry can with water and wedge it between the flue of my woodburner and the wall I built as a heat sink.
A lot of the heat is wasted going up the chimney and this would hopefully act like a night storage heater.
The second cunning plan is to affix a polythene curtain to the roof spars of my greenhouse thus enveloping a shelf I have with small apraffin heater on it. In effect a greenhouse within a greenhouse!

Paraffin heater + polythene curtain = big fire?

Am I right in thinking that the paraffin heater is going to be at head height too?

Pfff, don't doubt The Mighty Snadge you two!

I really think you ought to be on that Scrapheap Challenge programme Mr S!

Just about level with my chin!

Heater is shown in first pic, shelf on top left on second pic (Peak of greenhouse is about 8 foot high) and woodburner on third pic.

I have quite a few of the white trays the heater is standing on so will put these all down the left side with the curtain hung on outside of trays and stopping five foot before woodburner!
The timber stove fodder thats shown on the floor has all been chopped up and burned now!

Thanks for the show of confidence Seahorse, but I aint growing a handlebar mustache for ANYONE!

Put the second cunning plan into force today! I now have polythene curtains!

(Now where did I put that jerry can?)

Hi Snadger

You got me thinking with the heat sink idea. A few years back I had a lotti which had been left to go wild for years. In the old greenhouse (3 sides, no roof) were loads of pipes and a burner similar to yours all rusted to bits. When I spoke with a neighbour they explained how the old owner had heated several greenhouses just with that boiler and what looked like water filled scaffold pipes? I guess the expansion of water as it heats was enough to push it around the pipes but I think that would work better than a heat sink tucked in the corner?

Anyway hope it helps

A few of the blokes at the allotments heat there greenhouses with old central heating boilers that were coke fired when fitted to local houses. They aquired these when the council did re-vites and converted the council houses to gas.. These have a water jacket and two pipes top and bottom. Water flows along the top 'hot' pipe and returns along the bottom 'cold' pipe without a need for a pump.
These stoves are lined with firebricks and and can be banked up with coke or coal to give overnight heat if required.

Mine is a homemade stove and doesn't have a water jacket.It doesn't have firebricks either so can only burn wood. The five gallon jerrycan is my version of a water jacket which will be heated from waste heat off the flue pipe.................allegedly!
