  • Linking two Combi Boilers | Page 2 | DIYnot Forums

    Sep 16, 2007 · I have seen two 24 kW system boilers (what combis are) coupled up by having a 28mm pipe for the flow and both went into this. The system dictated a 28mm pipe to carry the 48 kW. The same for the return. Each system boiler had an auto by pass to protect each boiler and a non-return valve on the flow of each. So, each boiler pumped into the flow Get Price
