Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

It's all flats where I live, mate.

I looked up "heat pump" on wikipedia, and found this:


Note that when there is a wide temperature differential, i.e. when heating a house on a very cold winter day, it takes more work to move heat indoors, and it is possible that a heat pump's COP would be below 1 in such a case. In other words, when it's extremely cold outside, it's better to just make new heat indoors using a conventional heater, than to try to take it from outdoors using an air-sourced heat pump.

My ignorance on such topics is, well, now stated, but living where it can get cold for more than a couple of months every year, and where we heat a flat with radiators, which have their water heated by gas, which has gone up in price by 25% in a year, I like the concept of underfloor electric heating.

A search on google for "electric underfloor heating" brought up a load of businesses (so my non-investment investment has already been made by others.)  I clicked on a link, found a Q & A, and read this, relating to bathroom underfloor heating:


Question

Isn't it expensive to run ?

Answers

The devimat® tile warming system only uses as much electricity as a standard light bulb per m². The on-off cycling effect of the floor temperature-sensing thermostat can reduce this by as much as 50%.

It seems a huge market (and as gas prices rise, an ever-cheaper heating resource) for people who live in flats, though maybe not an idea for people who live in detached properties.

I don't see the "rip off" aspect.
