Hi, I am about to extend the heating system up into the loft. I have a combi boiler which can handle the extra rads and the system is running through 10mm micro bore copper pipe. I was going to extend from the 22mm flow and return pipes with further 22mm pipe up to the third floor and then to the rads with 10mm micro bore. Is this the best option?
I have been told that I could go from the 22mm flow and return on the 2nd floor straight up to the third floor and to the rads with 15mm pipe. This would be easier and cheaper can anyone advise on the best option?
I have already calculated the rad sizes using an online calculator! Both will be about 2750 BTU.
