Hi All,
I've just moved into an old house which is currently served by an old boiler for central heating and hot water, we estimate it must be about 70m of 28mm pipe to the boiler from the meter across a shared access bit of land. From the name it looks like a 40kW boiler (Chaffoteaux & Maury Corvec 1.140).
None of the tables go above 30m for pressure/flow drops and I am aware that newer boilers need more gas flow than the old one potentially does. Is there a way of measuring flow/pressure at my existing boiler to make sure the gas supply will be up to the job of a newer one? I'd rather know before spending out on a whole new system and then have to mole out for a new gas line and other expenses...
Thanks!
Rich
