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.
Thanks
Julian
Yes they do.
Danfoss Randall make one.
search on WP75-RF
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.

Their 'expert' said not.
The remote on my old Rover SD1 - part of an alarm/immobiliser fitted by myself some 15 years ago - does indeed sometimes 'lock up' for no apparent reason. It's an AM RF type. Luckily, I have an external disable key switch on it.
Never had a problem with the 'new' car.

Yes a lot of "experts" out there now;).
Well I've been discussion this with some of the OFCOM staff, formerly the Radio Investigation Service, and they see things like this on a day to day basis.
Its well known that a lot of key fob receivers are "wide open" to RF and most any local strong "ish" RF field will cause them to "block" and hence not work!.
The one on our Volvo is like that, and will play up anywhere near a TX site but my old Audi which still has a lump of metal is rather immune;))

Excellent, Thanks for the reference.
