Glowworm 35Cx Flexicom Condensing Combi Boiler

After only 4 years of service the water manifold had to be replaced which took the engineer about 3 hours because it was leaking, I think this is why the pressure kept going down,also when we have a bath the water is only warm unless we use the shower hose,they also quote the size of the boiler but this does not include the pipe work below the boiler that looks unsightly in a fitted kitchen,I will not buy another one of these boilers again.
