linking 2 worcester boilers

[divingwarrior]

I am looking at linking 2 worcester 30 kw boilers together. Can anyone give me any tips on how to go about it? The system is nat gas, sealed system with unvented cylinder. The house im looking to install them at is a big 3 storey with 3 metre high ceilings. The boiler he has at the moment is a 40kw keston, and they complain that the heat doesnt reach the 3rd storey very well. Shud i add another pump on 2nd storey?

If you are talking about the heating then I think you are seriously out of your depth!

What is the total heat output of the rads currectly installed there?

What is the calculated heat loss of the building?

You might as well link 10 together and still no heat on top floor if not designed correctly

If using system boilers the manufacturers way is to link the boilers with a reverse return and extra pump. The first thing to check however is that the existing installation has a pump installed on the system as the integral one included in the Keston is only designed to circulate water within the boiler and is unlikely to dissipate the output across the whole system. On the smaller 25C model the integral pump has worked for small systems.
