Underfloor heating(hydronic) beneath fridge freezer
 

We are about to lay the underfloor heating in our extension and i've started to think about which areas to avoid?

Should i be laying pipes under the fridge freezer?
I'm not expecting the water to be above 30C unless we get a stupidly cold winter so surface temp will be a few degrees below that.

During summer the floor will be used for cooling, or at least heat will be dumped to reduce overheating in the house. This summer we cooled the the existing floors to 20-21C. Without cooling temperatures get out of control fairly quickly.

I'm mostly thinking about the efficiency of the fridge freezer, which despite supposedly being A rated uses more than double it's claimed usage.

How about under a wood burner, is the floor likely to gain any heat which would be spread around the rest our the house?

Thanks Steve

Steve, it depends on how thick the screed is. I do not put tubing under it at all but if it is in a concrete slab of 3 or 4" the heat would migrate over regardless. If the screed is 1.5" (for example) on an over pour on a wood floor, there won't be as much bleeding of heat to affect the fridge.

Under a wood burner, I would expect some transfer as the temps are higher. It isn't enough to worry about.

Thanks Mikesolar

Screed will be 120mm thick on 140mm of insulation, bit thicker than the norm but that's the way the levels are working out to match the existing floor.

Think i will miss out the fridge freezer area, not that it will make much difference.

It may depend on fridge freezer model. Each fridge freezer has an outside temperature range. You can call to manufacturer and ask, could underfloor heating cause any problems with your fridge freezer.
