Strange!!!, in the admittedly very old tables I have, it says:

For a flow velocity not exceeding 0.75 m/sec (recommended for domestic)
22mm 7.6kW
15mm 3.07kW
10mm no figures.

Interesting; my new 28kW system boiler has 22mm outlets. Either it's
pushing the water round rather fast or it's not going to work when it's
cold.
