Starting to think about a possible upgrade of our CH system ...
currently we have a Vaillant boiler (probably getting towards the end
of its useful life, and undoubtedly not as efficient as a modern unit
would be) w/ a hot cylinder, running a total of 12 rads in three
zones. Just to add a complication, the boiler and hot cylinder
currently occupy a built-in wardrobe in a spare bedroom; the wardrobe
space also includes a *lot*
of pipework, some of which is left over
from a previous owner who had an Aga in the kitchen which was used to
provide hot water. Fuel is LPG.
- replace the Vaillant/tank in situ with a combi/condenser,
remove/re-rout as much as possible of the existing pipework to reduce
the amount of cupboard space taken up
- remove the Vaillant/tank, and put a combi/condenser in the kitchen
(which is directly below the current location - indeed, there is
evidence that at some point the boiler *was*
in the kitchen and was
subsquently moved upstairs to its current location). Moving would be
a bit of a pain in the a**
e, involving removal of at least one kitchen
wall unit and re-siting of the electricity meter / consumer unit; at
least there would be no major re-routing of the water or gas supplies.
[apart from the minor - but still significant - concern about having a
boiler in a bedroom, the noise that it produces could be enough to
disturb a light sleeper when the heating kicks in around 630am on
One further issue is that house is unusually long (approx 21m
end-to-end) and the CH boiler is located at one end. The internal
structure means that it would be (just about) impossible to re-site
the boiler to a more central location without significant/structural
building work. We do, however, have a utility room at the opposite
end of the house, so one option might be to go for *two*
combis, one in the current location (or the kitchen, below the current
position) and the second in the utilty room.
