A Heat Store is a very efficient way of using heat. A stove can be fired flat out to heat it, which is the most efficient
way to use the boilered stove. The stove can then be allowed to go out, with the electric controls distributing mains
pressure hot water and circulation water as and when required.
In choosing a heat store look for at least 100mm of insulation.
It can be plumbed directly to the stove but it must have the relevant safety measures and it must be a minimum
1800mm above the stove.
For size and heat calculations use 10 litres per square metre
One shower = 20 minutes = 10kw
40W/sq mtr new house
60W/sq mtr old house
80W/sq mtr draughty old mansion

ORDERING AND INSTALLATION OF RETROFIT BOILERS
All the models have a variety of boilers that can be retro-fitted and
have pre-drilled holes in the body and these
are covered with blanking plates which can be knocked out using a hammer (
do ensure
you have the right holes by
offering the boiler up to the holes
prior
to removing them) and when ordering boilers for retro-fit please state your
stove model as
some need a change of baffle.
i.e. for the 53000 Btu split saddle boilers in the 20kw.
Boilers replace the fire boards
and depending on the size of boiler to be fitted, remove the relevant board(s) or
part thereof before fitting the boiler(s). With slab boilers the rear fire board may be larger than the boiler; cut the ap-
propriate amounts from the fire board and fit them back either side of the boiler.
All the
boilers in the free standing models
have
1" Male BSP stubs.
SLAB BOILERS
The slab boilers available for your stove are detailed in the current brochure under general specifications. They are
available in stainless steel for 'Direct' Cylinders or steel for 'Indirect' Cylinders and have two
1" Male BSP stubs.
To fit the boiler remove the fire board and remove the relevant blanking plates. The two stubs are passed through
the stove body holes and the nuts and washers are sealed (with fire cement or high temperature mastic, where the
stubs come through the body) and tightened on the rear of the stove body. The higher boiler stub is for the gravity
flow which should rise immediately from the boiler in 28mm pipe and the lower is for the return.
SPLIT SADDLE BOILERS
Split saddle boilers are available only for the Wildwood
6Kw, 9Kw, 12Kw, 12Kw Plus, 16Kw and 20Kw
, and are
supplied as
two separate L-shaped boilers.
It is imperative that the plumbing of these boilers is done with the
utmost care and full notice is taken of the above fact. These boilers are available in steel for 'Indirect'
Cylinders only and each individual boiler has two
1" Male BSP stubs.
To fit the boiler remove the fire board and the relevant blanking plugs from the back plate of the stove. The two stubs
are passed through the stove body holes and the nuts and washers are sealed (with fire cement or high temperature
mastic, where the stubs come through the body) and tightened on the rear of the stove body.
The
two halves must be horizontally joined
in the following manner (diagram 10)-
connect the two higher out-
let stubs
for the single 28mm main gravity flow which should rise immediately from the boiler,
connect the two
lower outlet stubs
and bring your 28mm return to this link.
