Boiler choice for large family house

Look harder!

Mine is in the loft and it is the best place for it!

To get anyone to quote, you'll need a boarded loft, electric light, a fixed (but retractable if desired) loft ladder and hatch guarding. It is also better with insulated rafters, rather than floor, to avoid any freezing issues.

Also expect a larger bill unless you're going to be running the cables/pipework yourself.

An indirect unit allows you much more choice of boiler and the rest of the system because the stored water is separate from the boiler primary and fed from a smaller internal tank. You can use a sealed primary system, for example, and choose virtually any boiler.

A direct unit is useful if you were going to use a conventional boiler, which operates more optimally with long burns using the water directly from the cylinder. The boiler side has to be run open vented and that may have an impact on boiler choice as some require pressurised operation. You could run the CH from the store as well with a conventional boiler.

If you are going to use a condensing boiler, then an indirect store is a better choice, with a hookup as shown in Albion's Indirect diagram. This is because the boiler can modulate down to low power and best efficiency when driving the radiators and full power for the cylinder for the short period that it takes to heat the cylinder.

You could easily put this unit in a cold area - they are insulated. In a garage, I'd probably build a small cupboard around it and insulate that as well to further reduce heat loss.

Oh dear. Many are officially a two person lift, but I am sure that most fitters manhandle them in kitchens on their own.

Perhaps you could rig up a winch over the loft hatch.....

Or use a piston lift.

Yep, and at this time of year more people are indoors and it gets dark earlier.....

Can you imagine what would happen if the box split or something else went wrong?. It would make Peter Parry's canoe story sound like a kids party.

Thank you for your answer. That's just the level of detail I was looking for.

Before I was thinking of an all-in-one unit. I guess if I go for a separate boiler and store they will be easier to lift. I guess a modern condensing system boiler would be a good bet to go with the indirect store.

BTW: Do most boilers have their controls integrated on the boiler or are they available as a remote unit? I wouldn't want to have to go in the loft every time I need to change a setting.

Er, yes. All subjective opinions with not a single quantifiable statement. For example:

"We've got a big single bath, nearly a double" - No indication of actual capacity.

"Fills that without any problems" - no reference to water temperature, volume or time to fill.

"Certainly doesn't run out of hot water but takes quit a while to fill purely because of its size." - again no reference to volume, temperature or time taken.

So all you've provided is a set of statements from one person who is happy with their installation, but that provide no means for anyone to make a valid comparison against alternatives. Those statements are the sort of meaningless endorsements found in marketing brochures, not quantifiable metrics.

That would be a good choice.

Most wall-hung boilers weigh in the 35-45kg range so it really would be a two person lift into a loft space or some kind of hoist.

You can download installation guides from most manufacturer web sites which give all the details.

is useful because there are clickable links for most products and you can go from there.

Some have integrated timers although often that is optional anyway.

You would have the room thermostat or room thermostat and programmer integrated in an appropriate room without TRV on the radiator.

Boilers may have control panels for system parameters and to report faults. Usually these are used when setting up and not a lot after that.

Those that have integrated controls should have a way to use an external programmer. Check the installation manual for that. Some more sophisticated boilers have provision for showing boiler operation on a remote controller. You would then have a thermostat on the cylinder to control its temperature.

If it helps, don't forget that there are wireless room programmers and you can avoid wiring.

You would need to provision a gas supply - probably 22mm pipe - from the meter or teeing from a 22mm pipe from the meter.

Also for a condensing boiler, there needs to be a way to get rid of the condensate. This needs to be in plastic and commonly 22mm overflow pipe is used for it. In a loft, a convenient way may be to run it via a trap into the soil stack as long as the stack is plastic. Otherwise it needs to be delivered to a suitable drain as the condensate is mildly acidic.

I've never heard of that but FWIW one of the things about the Keston Celsius that is useful in our church installation is that you can wire the run and fail signals to remote neons.

It was an option for some of the boilers when I was looking around.

I have it in mind to modify my Keston for remote operation of the control panel. I have been breadboarding some ideas. I've been using the "lockout" and "burner on" outputs since it was installed.

Why make it complicated. Just give the herberts exlax chocolate and done with it. The whole trick or treat thing is imported nonsense anyway.

WHat happened to "penny for the guy"?

Carol singers belt out one line of "we wish you a merry christmas" and ring the doorbell wanting money.

It's no good.

They probably don't want chocolate anyway. Cigarettes for the juniors and ecstacy for the secondary school neds.

Inflation, Thatcherism, free enterprise.

Never mind, I expect there'll be a nice sing-song to the record player down the day centre. But I don't think I'll get a parcel from the Round Table this year[1].
