Plumbing regulations for stoves.

[Phil Pascoe]

I'm in the process of sorting a hearth for my new stove, and I wish to take the boiler pipes out through a wall to the side, so they rise in an adjoining bedroom for additional heating there without installing a radiator. I will not be doing this myself but it probably won't be done right away due to cost, so I haven't involved a plumber yet. The stove fitter is of the opinion that the pipework will have to rise on exiting the stove and not go through the wall. Does anyone know? I can't seem to find the regs. on it, and it might affect the shape and size of the hearth.
Phil.

I would think that the pipe needs to be rising from exiting the stove, but not necessarily straight up - any reason why it can't go through the wall at an angle? On the primary loop of a stove you need a constant rise to avoid thermal traps between the stove and the heat sink radiator. The stove fitter's manual has a load of good resources on boiler stoves.

Additional - what I think you want to do is described here: http://www.stovefittersmanual.co.uk/articles/connecting-a-wood-burning-stove-to-central-heating/

"Good practice: If you have to go horizontally make sure you go vertically first, as close to the stove as possible, to get the circuit going (a common scenario is to leave the stove on a slight rise, travelling through the sides of the chimney breast before following the breast vertically upstairs to a heat sink)."

I can't see why you shouldn't do what you want to do. Is it a gravity system? That's the only thought I have as to why he might be against it - maybe a right angle bend interfering with the gravity flow. But if that were the case then a swept elbow would do the trick.

It'll be gravity - it only goes to an immersion, not radiators.
