I once had a bulk lpg tank in the back yard feeding the combi boiler thats in the back of the garage. That tank is defunct now, and I am having a tank fitted in the front garden. I had planned to get the gas piped in through the front wall of the house and connected to the gas pipe that services the kitchen, that pipe comes through from the garage at the back. It’s 15mm copper.
The pipe is about 35’ long altogether, from where the bulk lpg will joint it, to the combi boiler at the far end. I’ve been wondering if the pipe size is big enough to feed gas the extra distance and still have enough pressure at the boiler.
I recall having to increase the pipe size when fitting a bigger boiler at our old house, but that was mains gas that is less than a tenth of the pressure of LPG.
My boiler is a Vaillant eco tech plus 831, no idea what KWH that is, but I’m in a 2 bed bungalow with no bathtub, so it only supplies central heating and hot tap water.
The gas pipe inlet for the boiler is 15mm, so I‘m hoping that I don’t need to increase the pipe size all the way through the house.
