Hello from France , you have nice radiators :)

I was concerned to note that the outputs claimed by various manufacturers are not to a required specified standard , ie they can do their own tests rather than being obliged to use a British standard . Of course finding out who does test to British standard and who doesn’t is a pain . I have opted for what I consider very ugly K3 Stelrads as they do test to BS fir their outputs ,,would have like to have something far less intrusive for the heat pump change .
