While the gadget that adjusts the flow return temperature is a great idea, it basically means that the radiators in the house aren't big enough. Either the radiators were installed in an age where condensing boilers were unusual and the boiler upgraded later, or the installer didn't do their calculations correctly. Bigger radiators allow the same heat output using a lower more efficient flow temperature.

In my locale the installer does just that. Install. Perhaps some calculation in order to sell you a bigger capacity, but certainly not optimization. Even talking about optimization with only high school physics with the people like installers and energy advisers gets you blank stares quickly. I think the benefits could be like 10% on your gas bill, but alas it’s untapped potential for those not into DIY.

  Once you contact a slightly bigger company - say over 5 folks - you'll usually get one actually mastering their skill, for the initial talks. Then of course they'll send the lowlies to actually install and that's okay too.

This is outgoing flow temperature thermostat, adjusting the heating curve based on outside temperature. A very basic component which is on every single water based heating system in the Nordic countries. I am baffled why this is not a standard part. This component can also adjust the flow rate and the temperature of the water. A more advanced system can look ahead the coming weather AND price of energy and use thermal capacity to overheat / cool the building ahead of time.

  In large parts of the US it rarely gets much below freezing. I'm not even _that_ far south (35 degrees N lat), and the coldest month of the year has an average daily low of 0.5C. Coldest temp ever recorded here was -20.
