In our Strata, we have district heating from Hafslund, and old MMA radiators. Its always a bit hard to know your consumption, but I have always gotten money back from our strata fees.
The radiators themselves are ok, but its extra work to regulate the heat with the manual thermostats, and lots of unnecessary heating when we aren’t home.
A neighbour recommended Tado Smart Radiator Termostat. I also looked at the Danfoss solution which might have been more suited to our MMA (M28) radiators, as Tado doesn’t include an adaptor for M28. But Danfoss didnt have any of the integrations I was looking for, so went with Tado.
I bought a Tado Smart Radiator Thermostat Kit, and 2 ekstra Thermostats, so I had a total of 4, 3 for the kitchen living area, and one for the basement where we sleep. They where programmed with calendar control, for automatic night and day adjustment, and adaptive heating for the hours we are at home.
It wasnt elegant to get them adapted to the MMA ventilators, but with an adapter it was acceptable, and they work well enough as long as you dont do them up to tight. There is not enough travel in the pin if you do it too tight, so it wont be able to shut off completely.
The consumption last winter looked like this:
Gauge 16/17 17/18 Diff 671 1667 1650 261 1641 1350 908 4 1765 094 1637 1954
What will it be in winter of 17/18? Will it reach the 20% advertised saving?
