A key question is - why isn't outside air temperature modulation of the flow set point standard on UK boilers? Adds a little to the cost, but would save users £££.

It’s not too late for European rivals to catch up — but first, they have to decide whether they want to accelerate into a battery-powered future, or keep grinding their gears in reverse."

Perhaps we need to think about better controlling solar gain and heat gain in our buildings, before diving into AC. 2/2

Electricity for air con, if it is from a clean grid, is fine. However, the grid is not yet clean, and the refrigerant could be problematic if it has a global warming potential (gwp) and leaks. There's also the issue of added load on the network in the middle of the day from AC. 1/2

Decent showing against a good Dutch team. A goal would have been nice, though.
