SEALED SYSTEM REQUIREMENTS

GENERAL

Note.

The method of filling, refilling, topping up or flushing sealed
primary hot water circuits from the mains via a temporary hose
connection is only allowed if acceptable to the local water
authority.

1. General

a. The installation must comply with the requirements of

BS.6798 and BS.5449.

b. The installation should be designed to work with flow

temperatures of up to 82

o

C.

c. All components of the system, including the heat

exchanger of the indirect cylinder, must be suitable for a
working pressure of 3 bar (45 lb/in

2

) and temperature of

110

o

C.  Care should be taken in making all connections

so that the risk of leakage is minimised.

2. Safety Valve

A spring loaded safety valve complying with the relevant
requirements of BS.6759 must be fitted in the flow pipe, as
close to the boiler as possible and with no intervening valve
or restriction.  The valve should have the following features:

a. A non-adjustable pre-set lift pressure not exceeding 3

bar (45 lb./in

2

)

b. A manual testing device.

c. Provision for connection of a discharge pipe. 

The valve

or discharge pipe should be positioned so that the
discharge of water or steam cannot create a hazard to
the occupants of the premises or cause damage to
electrical components and wiring.

3. Pressure Gauge

A pressure gauge covering at least the range 0-4 bar (0-60
lb./in

2

) must be fitted to the system.  The gauge should be

easily seen from the filling point and should preferably be
connected at the same point as the expansion vessel.

4. Expansion Vessel

a. A diaphragm type expansion vessel must be connected

at a point close to the inlet side of the pump, the
connecting pipe being not less than 15mm (

1/2

"

nominal) size and not incorporating valves of any sort.

b. The vessel capacity must be adequate to accept the

expansion of the system water when heated to 110

o

C

(230

o

F)

c. The charge pressure must not be less than the static

water head above the vessel  The pressure attained in
the system when heated to 110

o

C (230

o

F) should be at

least 0.35 bar (5lb/in

2

) less than the lift pressure of the

safety valve.

For guidance on vessel sizing refer to Table 6 in Frame 6.
For further details refer to BS.5449.  For IE refer to the
current edition of I.S. 813.

5. Cylinder

The cylinder must be either of the indirect coil type or a
direct cylinder fitted with an immersion calorifier which is
suitable for operating on a gauge pressure of 0.35 bar (5lb./
in

2

) in excess of the safety valve setting.  

Single feed indirect

cylinders are not suitable for sealed systems.

6. Make-up Water

Provision must be made for replacing water loss from the
system, either:

a. From a manually fitted make-up vessel with a readily

visible water level.  The vessel should be mounted at
least 150mm (6") above the highest point of the system
and be connected through a non-return valve to the
system, fitted at least 300mm (12") below the make-up
vessel on the return side of the domestic hot water
cylinder or radiators.

b. Where access to a make-up vessel would be difficult by

pre-pressurisation of the system.  Refer to 'Filling.'
