Old unvented cylinder replaced today in a loft. Old internal bubble on old cylinder was constantly failing and the D2 pipework was not installed correctly so the tundish was spilling over constantly. Cylinder was badly scaled up inside which was causing poor flow rates and there was a leak on the hot outlet behind the cylinder. All replaced with a Gledhill indirect 150 litre unvented. Just lagging to do when I return to do some other bits in the property.
