Another Cunning Invention

[dextrous]

So we all read on here, from time to time, queries about how to change a lockshield to a TRV, and the associated problems of draining down, changing pipework, flow or return, one-pipe systems etc, and then all the problems of refilling, airlocks, newly acquired sludge build-ups etc.

So, how about this - developing a one size fits all actuator type thingy which will replace the current plastic k nob and which is basically an electric motor that rotates, but which is controlled using a thermocouple type thingy placed somewhere nearby (or possibly as part of the housing itself).

Thus room gets warm, and the existing valve is closed via the motor, and vice versa. No fitting skills required - it just clamps over the existing valve.

and approximately a year after it has been "installed" the lockshield gland leaks like a bastart and requires your dreaded drain down/bung that most of us do 10-20 times a week without a hitch.


do it properly, install a decent TRV and forget about it.

also, one size fits all is impossible IMO.

Technicalities, technicalites.

Anyway, my invention would make me rich for a bit, then all the plumbers out there who would have to replace the completely screwed up valves. Everyone's a winner

did you invent the magnaclean? sounds familiar.

It's still in the dvelopment stage- I'm looking for a backer. You interested?

No fitting skills required.

.... just an electrician to provide a spur next to each radiator for powering the valve.... or a plumber who's done his "part p" one day wonder course...

why not make a lockshield top for a TRV base?

they have decorators caps to lock it down for taking it off don't they?

while this doesn't get around the new for old problem it would make future installation changes easier by making the valves universal..

Honeywell do a wireless valve

Only 2 zones so if you want more zones you need more kit.
Verrrrrrrrry expensive compared to a walk around the house and some common sense

a one size fits all actuator type thingy which will replace the current plastic k nob and which is basically an electric motor that rotates, but which is controlled using a thermocouple type thingy placed somewhere nearby (or possibly as part of the housing itself).

So the motor replaces your hand and turns the valve on/off as required?

The only problem I can see is that each valve has different characteristics - number of turns from open to closed, relationship between turns opened and flow rate etc - that each valve/motor combination would have to be individually calibrated.

The other thing is that a TRV is not an on/off device, it's proportional.

No he isn't!

Drayton have done this already - the Radset. You can also buy special covers to change the Drayton TRV body into a LS valve.

Exactly - so I don't need to make one as it's already on the market. Blimey Mr Hailsham, you ain't 'alf daft at times
