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.

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..
