We are planning installation of a gas fired combi boiler for a 3 bed, 3 floor, house, and a gas (dual fuel to be precise) range cooker.
I will be using a professional tradesman to do the job in due course and they will of course advise on the route. However some tradesmen have come before and offered such different opinions that I would like some information in advance to help me to more firmly specify the gas route for the job tender, and make structural preparations for the laying of the gas route.
I have a route in mind for the pipe run to the boiler and cooker (naturally I am open to suggestions from a professional or person more experienced than I).
The proposed gas route goes from the supply box about 12 metres horizontally and with 3 turns to a T piece. From the T piece it goes a further 1 metre and 1 turn to the cooker. Also from the T piece the pipe goes a further 10 metres, including up a floor, and a further 4 turns, to the boiler.
I had in mind permanent welded copper piping because I (maybe wrongly) think that it being more permanent it is more safe. Plastic is cheaper. Is the consensus in the trade that copper is necessary?
Should I go for 25mm or 28 mm pipe?
Does anyone see any concerns with the number of turns in the pipework?, particularly before the combi?
Is it worthwhile using "long turn" turns instead of sharp turns?
Many thanks for your thoughts in advance.
