Underfloor heating, any plumbers?

Update, we figured the underfloor thing was going to be a right pain in the rse, so forgot about it.

Finally replaced where the boiler lived in the fire with a chunk of inch plate (f*** me that took some cutting wit oxy-acet!), TIG'd up the ash-box where whatever arfa-jobbin swine had just tacked it up, and got rid of the letterbox-flap, instead rivetted a bit of 1/8" plate to the back of box covering the opening entirely, TIG'd a 1 3/4" elbow to that, bit of pipe and put a disc inside as a butterfly valve.

Works a treat, burnt about half a bucket of coal in last 5 hours and it's warm as toast in ere.
