I HAVE A STANDARD BOILER AT PRESENT. I NEED TO REPLACE IT BUT CANNOT RUN A 22 MM GAS PIPE THROUGH THE HOUSE AS I WILL HAVE TO RIP UP NEW WOODEN FLOORING AND NEW BUILT IN WARDROBES. IS THERE ANY WAY AROUND IT BY STILL USING THE 15MM PIPE ALREADY IN PLACE?

If the new boiler requires a 22mm pipe the answer is no. Your corgi registered installer will explain why.
