Hi all,
I'm looking at fitting an unvented electric water heater in a ground floor cupboard to replace an old immersion tank. Might fit a Hyco Powerflow or an Eldom if they're any good. ?
Anyway, as the cupboard is in the centre of the house there is no way to run a discharge pipe other than upwards into the loft. Is it permissable to have the pressure relief valve connected to a pipe which goes up into the loft and then out the soffit or does there have to be a tundish next to the boiler? Any advice appreciated.
