3.4 INSTALLATION - DOMESTIC HOT WATER

Installation of the domestic hot water system requires:

Check mains water supply

•

Connection to cold water supply

•

Installation of the cold water combination valve

•

Installation of the solar rated thermostatic mixing valve

•

Connection to hot water outlets

•

Installation of discharge pipework from the Temperature & pressure relief valve and

•

expansion relief valve.

3.4.1 WATER SUPPLY

The mains water supply to the property will be supplying both the hot and cold water require-

ments simultaneously. It is recommended that the maximum water demand be assessed and

the water supply be checked to ensure this demand can be satisfactorily met.

A high mains water pressure will not always guarantee high flow rates. Wherever possible

the mains water supply pipe should be in 22mm copper pipe or 25mm blue MDPE pipe. The

minimum mains water supply requirements should be 1.0 bar (dynamic) and 20 litres per

minute flow rate. At these values outlet flow rates may be poor if several outlets are used

simultaneously, the higher the available pressure and flow rate the better the system perform

ance will be.

The Electromax Solar unvented cylinder has an operating pressure of 3.5 bar which is controlled

by the cold water combination valve. The cold water combination valve can be connected to

a maximum mains supply pressure of 16 bar.
