I've been told that you need to leave one radiator without a theromostatic valve for the central heating to work properly. Why's this and what problems would it cause if all had trv's fitted?
It may be a design flaw in the piping,probably do not have mono-flow fittings at radiators,and you need to keep 1 radiator open for water circulation.
