Thermal store

GM, you should have added some insulation underneath the tank, you'd be amazed how much heat is lost without it.

I have, the pallets are full of it. You can't see it.

On closer inspection you can see it, didn't spot it the first time I looked.

That's some cracking construction going on there, good work

I was meaning on mentioning -

Someone on the navitron forum built similar.  It was a long thread, but without conclusion, as the chap moved before it was sorted.

If you do a search for "gravy" youll find it.... : /

Cheers. I'll take a look.

I remember thinking that the other chap's key failing was that there was no real way of keeping the oxygen out.

I see no issue with steel stores at all (plenty of people do, it seems) but i fear that you may need to seal up the system better, so as not to have the same issues?
