Domestic Hot Water Services
These results cover pipes and fittings up to DN250 size for domestic hot water supply within buildings, for use up to a maximum operating pressure of 10 bar. This includes:
Stored hot water pipework
Supplies hot water from a vented or unvented cylinder. A commercial unvented cylinder commonly includes an inlet pressure reducing valve (PRV) and expansion relief valve set at 8 bar or 10 bar.
The domestic hot water (DHW) temperature setting of hot water cylinder is normally between 60°C and 65°C. Domestic hot water may be stored at temperatures above 65°C e.g. solar heat source, before the downstream blending valve.
Instant hot water pipework
Supplies hot water from an instantaneous hot water appliance such as a combi boiler. The DHW temperature setting of a combi boiler is normally below 60°C.
Includes pipework downstream of any blending valve if fitted

Check with the manufacturer for exact pressure ratings.
Pipes and fittings must be suitable for use with potable water and be UK Reg 4 compliant.
Please ensure when choosing polymer products for pipework, that polymer pipes and fittings intended to be used together, are of the same material and meet the requirements of the same standard.
When contacting a manufacturer, please advise that the pipe selector tool has been used.
