Edit to add: surely copper is adequately long lived, unless you're planning on showering in salt water or battery acid??

 

Good point. Even less reason to buy this one

Good find @Onoff makes it worth doing for £170. Not sap listed though

I really would have to look up what SAP means to be honest!

 

I just look at something and think could I do that different/better. Even if I can't or it fails. I'll invariably have a go even if it ends up costing me a few quid. Keeps the old grey matter ticking over.  Generally starts with looking at the shape of something and what's similar. With this I'm thinking about  a wine making airlock.

 

 

Ditch the top bit and fit a "cone" over the centre tube. Hot waste water goes in the top. Heat exchange coil goes around the outside to maximise surface area. "Cold", heat depleted water exits down the middle.

Sap means nothing really unless your planning has it as a condition. I am all-ready at 97 with standard modelling so it is really a case off "mine is bigger than yours"

It's sourcing the sustainable energy floor tiles that's holding things up. 

Try Whoopy Cushions, all the chuckling will soon warm a room up.

Pretty sure I read once that 15 cats in a radiator shaped cage would keep the average room warm.....

In case anyone was considering a system
