Hundreds of times, but depends on your flow rates 😛
I normally say 15mm will take 5-6kW. What's the output of the circuits you're feeding?
If it's a combi I presume it's a sealed system.
Roughly speaking I always think up to around 20000- 25000 Btu's / hr.
There are other things to take into account though pipe runs, distance, temp, Delta T's etc.
That's why I think it is always best to get an experienced Heating Engineer in. If you try and take too much, you'll wish you hadn't.
