Does anyone have practical experience of fitting one.

I have been trepidating over ordering a log burner with CH boiler
basically because I suspect the coil on my existing hot tank is too low
for either version of the neutraliser to work under gravity alone.

Raising the tank is not very practical as it would then bulge into the
loft. A second hot tank could be installed but with what benefit?

As a sideways step I have ordered a log burner which can have a CH
boiler retro-fitted while I seek counsel:-)

Hi Tim
I fitted one some 15+ years ago. It's a challenge plumbingwise if
you've got only a small space; a plumber doing it would take in a long
suck of air and warm up his calculator. May well be easier with
modern plastic pipes.

My ceiling height is nominally 9ft and I've got the tank on a frame
such that it's base is 6.5ft above the floor and it just pokes through
the attic floor (with a cupboard above for wine making and the CH
header on top of that!). I'm not sure quite what counts as the head
above the stove but the bottom of the saddle tank is about 10" above
floor level.

Does that help - by all means come back with any questions.

I'm grappling with the idea of 9ft. high rooms!

This is a two storey farmhouse with an *included attic* construction so
in most places upstairs I can easily lay a hand flat on the ceiling.

The intended boiler position is almost directly below the airing
cupboard and, at a pinch, I can bring the gravity riser in at floor
level.

My existing hot tank stands on the floor and terminates just below the
ceiling! Immersion heaters have to be fitted from the loft.

My first stumbling block is failing to understand the neutraliser
installation instructions downloaded from their website. For instance
boilers are categorised into 4 classes without explaining whether this
refers to the existing boiler or the one you wish to add!

As Dunsley seem willing to get involved in the system design, I should
perhaps write to them explaining my intentions and see if they can
clarify things.

It is reassuring to know that someone has a successful installation:-)
