You could try storage heater bricks all around that stove, would be s cheap upgrade for now. But really, a rocket mass heater together with cob or masonry bricks would be a good job.

I use paraffin heaters for the past 10 years. You can run them quite cheaply on Kero. But thats is fumier than using paraffin/ROLF. Currently, I use Tozane (ROLF) in a home office large caravan. I wouldn't use kero in this situation but have done so in a large well ventilated room.

I have to admit I am currently looking at some vids on this and its construction methods. I confess I am impressed and drawn towards it as a heating source for my workshop. I will give it strong consideration, as i dont think its too labour intensive, and seems to have excellent outcomes.

Left of field... But I got an old Bitcoin miner. It's noisy but I earn close to the cost of electricity and it heats up my 24sqm workshop in no time. I also have a load of old oil and do plan to make a rocket stove at some point. But the comment on vapour is something I had previously considered.

One of the most unusual approaches to workshop heating that I've heard - I love it!

I've got a few old PCs around, so I guess I could set up a really inefficient mining farm and try something similar but in my case there's no way I could get close to covering the costs with the level of processing power available!!

I got one of them too.
Installed it ourselves.
2 x 6 inch holes in the wall and bobs yer uncle.
Works like a freezer in reverse. It draws heat from the air outside. PAsses the air inside over the radiarot fin type thing inside and blows it out hot.
Dont put your hand near the cold exiting air outside unless you want frostbite
Make sure you buy one that is powerful enough for your space though.
And like you said. The couple of days you need it in the summer it reverses to aircon at the touch of a button.

I also have a heated gillet that i wear when its very cold outside. Maybe one of those would help til you get your heating sorted.
Now i need heated socks

No. Air to air. Think aircon on the continent, but in reverse.

Sticking with this concept, have you access to a stream, lake, slurry pit, for a water to air HP

No I have not. I have a 320' bored well.....any use??

Not savvy on water to air heat pump at all. Too busy looking at rocket mass heaters at the moment.

So taking on Space X etc!

Anyway W2A is a bit pricey but very effective as the water stays more or less at the same temp all year, where as the A2A suffers from what we had last week and lower conductivity.
Come back if you need more

Would it suite a workshop though. I would assume that it's small increase in temp over a long time gets the space hot . Would it be expensive to run ina draughty and pearly insulated shed.

1 & 2, not really and yes, which is why the IR option is better, either from wet rads at ceiling level or the radiant elec or gas tubes at ceiling level

Don't know if you got sorted Kadman but Bohills in Drogheda do reconditioned stoves very reasonable.. I was looking at a very nice one there just before Christmas for €200. Might be worth a call.

I have an old handy size stove at home that has no use for the house. Was thinking about putting it into the workshop instead. Its 7M x 5M, 50mm kingspan insulated.

Is there any risk of introducing moisture (earlier mentioned in thread).
Also, is there any carbon diox risk, assuming it will have a flue out through the wall.

Appreciate any replies, as I dont know anything about this stuff.
