A bit of advice guys please, about 3 years ago I replaced my old Glowworm fuelsaver MKII that I installed in 1986 (in the days when you could) previously worked in a local shipyard in metal work, always around the plumbers etc. I had it replaced with a Valiant 418 eco tec boiler, also at the time I uprated the old cold water tanks/feed tanks in the loft and had installed by my plumber colleague from Shipyard says, to a pressurised hot water cylinder (wonderful). however the glow worm was noticeably slimmer than the valiant, in that it did not protrude from the wall as far as the valiant does, (I have a small kitchen ) the condensate drain is discharged into the soil and vent pipe which comes down to the left hand side of the boiler, by way of a saddle fitting onto the soil pipe and a non return valve on the condensate drain under the boiler. I have good pressure on my system and it never drops pressure, or for that matter needs pressing up, my question is this, re site the boiler to the gable end, run the 3/4 inch plastic condensate drain through the loft with a suitable fall, to pick up the vent pipe in the loft which is there.
So basically it is now a fully pressurised system with no feed tanks whasoever in the loft
