2 Water Sytem

2.12 Pressure Gauge

A pressure gauge with a set pointer and covering at least 0 to 4bar (0 to 60lb/in2) shall be fitted permanently to the system is a position where it can be seen when filling the system.

2.13 Domestic Hot Water Cylinder

SINGLE FEED INDIRECT CYLINDERS ARE NOT SUITABLE.

The hot water cylinder must be of the indirect coil type. It must be suitable for working at a gauge pressure of 0.35bar above the safety valve setting.

2.14 Water Makeup

Provision should be made for replacing water loss from the system using a make up bottle or filling loop mounted in a position higher than the top point of the system, connected through a non-return valve to the return side of either the heating circuit or the hot water cylinder.

Alternatively, provision for make up can be made using a filling loop.

2.15 Filling a Sealed Water System

Provision for filling the system at low level must be made. Three methods are shown in diagram 2.5. There must be no permanent connection to the mains water supply, even through a non- return valve.
