Heatrae Sadia 95.970.356 Unvented Water Heaters – Shop4 Electrical

Description

Pack U5 Expansion vessel and check valve
The expansion vessel when fully charged, will absorb all expanded water produced by the Hotflo heater during normal operation.
Connection:
1/2″ BSP male; precharged 4.1 bar.
The check valve prevents backflow of hot water and eliminates any possibility of crosscontamination between cold and hot water.
Connections:
15mm compression.
Installation:
Pack U5 must be fitted on the inlet side and in close proximity to the heater.

Accessories:
A full range of accessories are available for installation with Hotflo 10 and 15.
These are supplied as accessory packs.
When installing small unvented water heaters, it is essential that the correct accessory packs are used.

If the expansion in the cold main is restricted, for example by a stop valve, check valve or water meter, an accessory pack which includes an expansion
vessel must be fitted.

A knowledge of the maximum incoming water pressure is an essential requirement prior to installation; where this is not known the local Water Authority should be consulted.

Thermostatic blending valves allow water to be stored at high temperatures and blended with cold water to a preset outlet temperature.
This provides over-temperature protection, and is ideal for the control of Legionellae and the extension of system capacities.
