4-3.9 Thermostatic Mixing Valve
A Thermostatic Mixing Valve is supplied with the Electrastream. It should be fitted
between the cylinder hot water outlet and the draw off (taps). The valve mixes hot water
from the cylinder with cold water to provide hot water at the taps at a consistent
temperature.
The valve is supplied with two check valves which must be fitted to the hot and cold
supply.
It is recommended to fit a service valve on each of the three pipes to the valve.
