Radiant Ceiling Heat

Thanks guys. Did search on 'radiant heat' but did not come up with anything specific on this type (cable in plaster). Probably good news for owner / client!

I had this in a home I owned 5 years ago, all rooms worked fine, the inner walls all insulated and this was good for shutting down the temp in the rooms we did not use to much.House built in the 70's.

Many homes here have electric radiant heat in the ceiling. All I have come across so far have been via electric mats in the attic space, non from wires embedded in the plaster. Almost all have been functioning as designed and in use and working well.

I verify their proper operation without a thermal imaging camera, a simple ir thermometer works well.

People with them like the even distribution of heat and the ability to control each room (zone) independently. There really is little 'ghosting' effect, with any radiant heat source, as the object blocking the radiant heat itself radiates the heat it builds up so it is a very short term effect.

People don't like the speed of the heat, if you go on vacation for a couple weeks and turn the thermostat down to 50, when you get back it takes a few hours to heat up the house. Also, some are concerned with the price/efficiency of heating with electric vs. gas systems.
