Identify this please? Any ideas?

[Rudi]

On lifting an old carpet in the hall I found a metal plate in the (concrete)floor. removing it shows some sort of terminal block. Both wires are dead (tested with a neon screwdriver) and they appear to go into the garage and end in a length of pipe cut off and squashed shut. Anyone have any idea what it was for? I want to remove it and fill the box as it stands slightly proud and I want to lay laminate flooring. The house was built in 66

It looks like a thermostat. Does/did the house have underfloor electric heating? It is likely to have got/had a Night rate meter and two consumer units/fuseboxes.

I have a night rate meter but only one fuse box. I have gas fired radiators for heating, have not found any other evidence of underfloor heating, only been here since Christmas. My neighbours all have gas heating.
Thanks JohnD

Rudi,

How proud is "slightly proud"? Standard foam underlay should level protrusions of up to 2mm. If you use thicker fibreboard underlay you may be able to cover up larger protrusions removing the need to remove the box and fill it in.

regards

Fred

It's not significant as it is but I need to remove those horrible black tiles so the floor level is the same as the kitchen, then it's about 5mm. I want to laminet through the hall into the kitchen. thanks Fred

If the cables appear int he garage, and are disconnected, whats the problem with removing?

It does look like an old thermostat, but I have never seen one mounted in a floor before.

 

[Rudi]

I don't see a problem now but I've never seen one of these and thought it might need to be kept for future use. Now it's been identified as a thermostat (maybe underfloor heating) I have no use for it, so it can go.

Have you tried to pull the wires out of the conduit?

Is there any movement on them?

I've never seen one either!

 

[Rudi]

The wires have some slack but I think they're trapped about 3 feet away in the crushed end of conduit.

Definately an UFH thermostat, switching the full load on/off rather than a controlling contactor

you might find one in each of the ground-floor rooms (except maybe the kitchen)
