6.8Domestic Hot Water Circuit

1.All DHW circuits, connections, fittings, etc. should be fully in accordance with relevant standards and water supply regulations.

2.Your attention is drawn to:

for GB: Guidance G17 to G24 and recommendation R17 to R24 of the Water Regulations Guide.

for IE: the current edition of I.S. 813 “Domestic Gas Installations”.

3.A single check valve must be fitted as shown in Fig. 10 to prevent backflow to the supply pipe and to ensure the efficient operation of the expansion vessel which is required to accommodate the thermal expansion of the water.

4.When the domestic water system includes any device which prevents water expanding back towards the supply (check valve, loose jumpered stopcock, water meter, water treatment device) then an expansion vessel must be fitted (eg. Zilmet 160ml, R1/2 15bar).

5.If the hot water expansion is not provided for, then high pressures can develop which may result in damage to fittings and devices on the system.

6.The boiler’s maximum working mains pressure is 8 bar, therefore all pipework, connections, fittings, etc. should be suitable for pressures in excess of 8 bar. A pressure reducing valve must be fitted for pressures in excess of 8 bar. The manufacturer of any outlet fittings, such as a shower valve, may require a lower maximum pressure. The pressure reduction must take account of all fittings connected to the DHW system.

6.9Showers

1.If a shower control is supplied from the appliance it should be of the thermostatic or pressure balanced type. Thermostatic type shower valves provide the best comfort and guard against water at too high a temperature. Existing controls may not be suitable - refer to the shower valve manufacturer.

6.10Hard Water Areas

1.If the area of the installation is recognised as a HARD WATER AREA then a suitable device should be fitted to treat the mains water supply to the boiler. Contact your Water Distribution Company for advice on suitable devices.
