Radiator pipes - concrete floors

Recommended Posts

Apart from the mess & extra cost associated with chasing pipes into concrete floors, the heat loss from the pipes will increase being exposed to the cold uninsulated concrete floor. It would be much more efficient, less disruption / mess, and certainly lower cost to have the pipework discretely surface mounted and neatly boxed in.

Thanks for your comments. Mr Peacock, if the pipes are in the concrete and appropriately insulated, would there still be the heatloss? I think boxing in would be unsightly but i am aware that if there's a problem ie a leak then finding it in concrete is a mare.

speleo, they're using copper pipes. The pipework is currently boxed in

Even insulated pipe work loses heat. obviously at a lower rate than uninsulated pipe work. But in all cases the greater the temperature difference the rate of heat loss increase. For example, the heatloss through a cavity wall increases if the temperature outside falls, and reduces if the temperature outside rises. The same is true of the pipes in concrete. A cold uninsulated existing concrete floor will speed up the heat loss from the pipe work.
