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


Thanks for commenting - its cool that you took the time
