Hi everyone, I am about to take over a new build with most of the wiring completed. The only thing left is the heating, i have limited knowledge of domestic systems as i usually do industrial work. From my brief conversation with the plumber we have a polypipe underfloor heating regulator for one room that is to be controlled by a thermostat in said room. And the heating and hot water is to be on a single channel timeclock. The plumber has said there are no valves for zones as there is only one radiator in the building and that has a TRV. Hot water seems to be unvented system attached to an oil boiler. does this seem to be the conventional way of plumbing/wiring? Thanks.
