Hi,
I am going to be installing central heating in my new house and just want to check if my proposals make sense.
I'm going to get a Corgi in for a chat beforehand also to make sure they're happy with what I propose and are happy to commission the boiler.
I'll do it in a list of what I think needs doing / what I intend to do....
1. Install new 22mm copper pipe from Gas meter at front of house under living room floor then up into rear bedroom and across into airing cupboard. (Leaving open at both ends to be connected etc by Corgi) Total run approx 15 Mtrs with 13 bends resulting in an equivalent length of 21.5M. Total Max gas flow req'd is 2.3M3/h
2. Install radiators in each room, upstairs will be fed by pre-installed 10mm branched off a 22mm main feed. Downstairs will be two drops, one solely for the kitchen in 15mm, one for two rads, lounge and dining again in 15mm.
3. Hang boiler on wall connect up cold water, hot water, heating flow and return.
4. Connect overpressure vent through wall and go horizontally outside slightly before down and inch or so and facing wall. (This is to avoid the vent being directly above kitchen outside door.
5. Connect condensate drain and lag is it acceptable to run this internally across bathroom under floor to an alternative outside drain 'hopper'.
6. Fill system and flush through with cold water for a short period.
7. Fill with flush and leave for however long it says then drain and refill.
8. Corgi to then come and connect and test gas supply at both ends, install flue and perform boiler commissioning.
Does this all sound ok??? The only bits I am unsure about is the condensate drain and the flushing procedure.
Thanks for reading all this! Cheers.
