I like the idea of a heatbank or cylinder but I don't have unlimited

If I could get something similar to the highflow or linea max, but
with a slightly bigger store for not much more money I would probably
be happy :-)


Sounds as though a heatbank or pressurised cylinder in the in the loft
might be a good option.

Essentially you do away with the cylinder in the airing cupboard and
the roof tank and fit the heatbank/cylinder where the tank was.

Can someone explain the pros/cons of the direct vs the indirect
mainsflow stores? What kind of boiler would suit which store? Can
they be placed in a cold area such as a garage?


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.



You could also fit the boiler in the loft for that matter.
Perhaps that would help with flue location


I haven't found a fitter willing to lift a boiler into the roof space
yet!


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.....
