I had the house rewired about 18 years ago the electrician used 1 mm twin and earth from a 6 amp breaker in the consumer unit to a fused spur with 3 amp fuse for the combi boiler, I am about to have a new boiler installed and want to know if this cable is actually the correct size it has caused no problem but I would have thought 1.5 was more suitable.
3 Answers. It's always best to match a boiler to the output of the system, after all it is simple physics, radiators cannot give out more then their designed output (i.e a 1 kw rad can not output 2 kw's of heat). A 600x1000 single convector rad outputs approx 1kw so a 30kw boiler could heat up 30 of these radiators
May 03, 2000 · Contrary to what some first think, boiler return protection doesn't slow the rate at which the distribution system warms up. Why? Because the boiler is firing continuously during the warm up process. It's putting out all the heat it can during this time, and the mixing device is routing 100% of that heat out to the distribution system. Do #4.

All of this changes depending on how cold it is outside, of course.
A water-tube boiler is one in which the products of combustion pass around the outside and heat tubes containing the water.
