heating

hi all,,

Ive seen various posts on our local freecycle asking for old cooking oil to heat greenhouse over the winter,, Ok I can get hold of alot of this stuff but do we just just put it in a normal paraffin heater type thing or is there some other way???

another ?    what is the best weedkiller to use at this time of year?  general weeds,, need to clear a large space but don,t have time to dig it but it will cause problems next year If i cannot clear it,,  any advice appreciated..   

Please don't use cooking oil in your paraffin heater. It's just not that simple.

Here's more specific info on using it, which I suspect you'll not bother with:

The idea of using cooking oils is to convert them into biodiesel fuel which is then used in specially converted units. Its a great deal of work. Also, in the UK, the government requires taxation on it as if you bought fuel. So, lots to think about.

we had to help extinguish a shed this summer after a portable stove accident! can just imagine the smell of burning fat wafting over the plot....
