55 gallon drums and a wind turbine - Heating a shed on the cheap

I don't know if I will actually go this far, but certainly for a workshop empty half the year, just to keep the damp out - heating seems to be a good idea.

I may experiment on Delaneys shed first, after all - if it goes kaboom he'll be on the other side of the wall, and I don't think he'd complain too much. I figure it will be bricked in anyway.

I can neither afford the cost or the time of having a commercial connection and set-up, and if things can be done in a renewable way I'm all in favour of it.
If the idea works, then it is a once off cost, essentially, as long as there is wind, there is power - therefore heat - and in Connemara where trees grow sideways that's a good investment.
The picture above caught my eye, rather than an expensive (and very steal-able) copper cylinder, I will most likely try to find and convert a 55 Gallon drum as above. 

Elements etc. for 12/24 volt systems are reasonably cheap and available - whereas inverters seem very expensive.
24 volt pumps are cheap and easily available, as they are used a lot in cars and boats.


The idea of using a wind turbine is feasible as it will supply 12 or 24 volt power directly. 
Pumps etc. still need further exploration, a natural convection system would be better - less moving parts would mean less maintenance. 

Turbines at 300 watt and 12 or 24 volt are costing about €200 and getting cheaper, that would be the single biggest expense, heating elements are about €30so all in all its not a bad idea, but it will need a bit more research - still back of the envelope stuff, but if anyone is interested in helping out or developing the idea just drop me a line.

All feedback, ideas and suggestions are welcome - please do take the time to comment

  1. This is an interesting article. I have never seen a mass heater like this before. It is amazing what new technology they are coming out with these days. for Drum heater. Really your informative blog helpful for Drum heater
