Cylinder
The hot water cylinder must be an indirect coil type or a
direct cylinder fitted with an immersion calorifier suitable for
operating at a gauge pressure of 0.3 bar (5 lbf/in²) in excess
of safety valve setting. Single feed indirect cylinders are not
suitable for sealed systems.
Method of Make-up for sealed systems
Provision shall be made for replacing water loss from the
system either:-
i) from a make-up vessel or tank mounted in a position
higher than the top point of the system, and connected
through a non-return valve to the system on the
return side of the hot water cylinder or the return side
of all heat emitters, see Fig.6.
or
ii) where access to a make-up vessel would be difficult
by using the mains top up method or a remote
automatic pressurisation and make-up unit as shown
in Figs. 3 & 4.
Mains Connection
There shall be no connection to the mains water supply or
to the water storage tank which supplies domestic hot water
even though a non-return valve, without the approval of the
Local Water Authority.
Filling Point
The system shall be fitted with a filling point at low level
which incorporates a stop valve to BS 1010 and a double
check valve of an accepted type to be fitted in this order
from the system mains, see Fig. 3.

If the system is extended, the expansion vessel volume
may have to be increased unless provision has been made
for extension. Where a vessel of the calculated size is not
available, the next available larger size should be used.
The boiler flow temperature is controlled at approximately
82°C. The vessel size can now be determined from the
information in Table 1 where V = System volume in litres.
