Interesting points, Freddy. A brief response: 1. I entirely agree with 30kW to get the improved flow rate at minimal extra cost. More important for bath (my preference too) than shower, considering time taken to fill a bath and volume of water used. 2. I too was advised to run gas supply from meter in 28mm to boiler (about 40' run) if possible, bearing in mind that supply to hob branches about halfway. In fact, I continued beyond the branch in 22mm and of course the boiler itself has a 15mm connection (perverse?). No pressure problems experienced. I have never seen newbuild outside pipework in less than 28mm, but I suppose smaller may be OK depending on what is being run. And the meter includes a regulator which does reduce the pressure somewhat so needs the larger onward pipe. 3. The WB boiler should certainly be worth something and you may be pleasantly surprised if you eBay it. I have seen s/h boilers go for surprisingly high prices. One problem is that, unless Sedbuk A rated (is it?), it is not now strictly lawful to fit it - but who would know? 4. God luck with the plumbing - especially with the condensate. Have you decided how/where to run that yet? 5. I have an indirect pumped system at home, with CW cistern and HW cylinder. As it is a solid Victorian house, the potential for cracked ceilings does not really arise for me. My CW cistern (50 gallons) is on a solid platform a couple of feet above the ceiling joists, but they and the supporting legs are all pretty solid (min 4 x 2) so the weight (or variation in it) has little or no effect. Mind you - the old round cistern I replaced was simply seated on the joists and had a nicely corrugated bottom; amazing that it never gave way.
