    I’ve been asked to upgrade a programmer to a wireless one but first I have to investigate various issues.

    Residents claim “Hot Water” controls hot water in taps and some radiators, and “Heating” controls other radiators. This seems to be the case.

    But draining lowest radiator drained all radiators which suggests they are all connected.

    How is this possible?

    Radiators and system will all be connected by the return pipes but separated on the flow by zone valves.

    That is 1 of those jobs that you start to wish you never started. I would give it a miss as you will never convince the tenants that you have done your bit correctly and will be back and forwards many times
