Still with solid floors, downstairs CH and cabling comes from above. If you have a doorway between to radiators you have to go back up and over and then down again. With stud walls I think the piping and cabling is hidden in the wall but what happens if you want to move rads or sockets? Stud walls, cheap fast erection but for me it does not scream quality. Hanging anything of weight or value on a stud wall, scary My daughter looked at a house last week, every wall upstairs and down is solid. Pulling the ceiling down and working from below is a good idea. Be carful going through a solid floor as you may go through a damp proof course. wife and I are in out 3rd house, each one has needed rewiring and new heating so I know what you are going through. My daughter is in her 3rd house and has done similar, the 3rd house she wrecked and then put it back together good luck macafee2 |

I think most of the internal walls are solid, and the existing rads are in good locations. Many of the rads have twin pipes coming out of the wall so easy to resize. If the existing pipe work is thick wall I’m loathe to remove it as it’s much better, should be able to flush selectively.

More thinking needed.

The best place for a boiler is midway between the kitchen and bathroom, it's not always easy to find such an ideal spot though. The old type boilers that have a cylinder in a cupboard are very old hat and not very effective at saving money, a modern combi condenser will be around 93% efficient and that means you'll lose 7 pence out of the £1 you spend on gas, an old system might be as low as 50% and you're throwing money away with one. In my house I have a 17 year old boiler that's still going very well, the % output is listed as fairly low on the Sedbuk chart but every pipe in my house is lagged with the foam covers, I then foil tape wrapped them all and there is no heat going to waste from them, I feel nothing when I put my hand on them, many people don't realise that a pipe that's not insulated is just wasting gas. The choice of boiler is a personal one, many say Worcester Bosch but I have much respect for the Biasi range, very well made and better value. The Biasi boilers I've put in over the years have lasted very well, the one in my parents house is over 12 years old now. |

Done this many a time when installing combination boilers, you can even assign it to its own zone so it has separate times.

I would advise against an intelligent thermostat, we had a new system fitted a couple of years ago and the engineer recommended we had one. It seems to spend most of its time trying not to have the heating on in various ways, delayed start, switching it off half an hour before and the final annoyance it only allows the boiler to be on for 20mins at a time even if the house has not reached the desired temp. Luckily all these crazy functions can be switched off but it now acts as a standard thermostat sowas a waist of money.

Central Heating replacement - modern future proof options
Quote:
I’m with you on most points here, that’s what we did here 14 yrs ago, ripped out the Primatic!!! Cylinder, replaced with a loft mounted Vaillant Eco Tech. Has done remarkably well, only had to repressurise the vessel a couple of times, but it’s a long way from it to the kitchen sink, not so bad for the bathroom and the remote shower mixer is in the loft next to it. We replaced the cylinder with a small radiator to dry stuff and warm the towels. As a four bed semi (same as now) but with just me and mrs there full time, it could be close between combi and pressurised. Will have to measure the landing to see what walls can be moved and where it all could fit. Would couple nicely to existing pipes if we went that route. Final decision soon after moving in then..

Only twice outside of my house have I seen a hot water "ring main". Hot water pumped from the cylinder to other rooms and back to the cylinder. This means when the hot tap is opened hot water only has to travel "5" feet

Oooo Primatic cylinder, ( power to your bubble ) try explaining that one to the combi chuckers. It was hard enough trying to explain why the hot water return had to be the last return into the system on a Y plan.
