Hello,

I need to update my heating system, toa fully pumped system. But
getting wires from the Hot water cylinder to the boiler controls will
be a real hassles with carpets and floorboards. I notice that
wireless Room Thermostats exist, but I have not found any reference to
wireless hot water cylinder thermostats. Does anyone know if they
exist ?

I am perplexed to know why they are not readily available.

Yes they do.

Danfoss Randall make one.

In some areas, wireless communication of this type is starting
to become unusable because it's reaching saturation. On Radio 4
today, there was an interview with one of the car breakdown
companies, and they are now getting rapidly increasing numbers
of calls for cars which can't be unlocked in some car parks,
because the keyfob transmitter signal is drowned out.

Usually by the new TETRA Airwave police system ,appx 385 MHz. Doubt that
the off wireless thermostat would affect a car outside the house at
all...

It is very likely that your evil neighbour will hack into your central
heating and turn it up and down at the wrong times.
