Hi all

Just a point of interest really....

Does anyone know whether heating system "design" is regulated for
new builds in any way?

Most contributors here I'm sure will know that, to run efficiently
in condensing mode, the system temperature for condensing
installations needs to be rather lower than older systems. This
means larger radiators are needed to supply satisfactory heat
input to a room with a given heat loss.

It is in the installer's interest to fit smaller radiators at a
lower overall cost. But this would lead to a higher less
efficient system temperature being necessary to sufficiently heat
the property.

Does anyone know if checks are done for heating system efficiency,
particularly on major builders' sites?

If not, then the claimed boiler manufacturer efficiencies will be
meaningless.

Thanks

Don't Building Regs make you adhere to something like the
SAP rating of the proposed construction ?.

A farming friend built a new bungalow on his land and the
BCO made him fit a particular type of fire-behind-glass
which he had every intention of removing so he could have
a blazing open fire instead. Not sure what the outcome was.
