Installation: FAQs


Are there any specific suitability requirements (regulation/byelaw 4(1)(b)) for hot water systems?

All water fittings must be suitable for the circumstances in which they are used. In addition to the normal system operating temperatures and pressures consideration should be given to the suitability of components for use at elevated temperatures likely to be encountered under fault conditions

The safety arrangements installed on a water heater used to heat water for domestic applications should prevent the temperature exceeding 100oC.

The suitability of safety arrangements for other applications, for example industrial processes will be assessed on a case by case basis.

Where the source of heat energy cannot be relied upon in all circumstances to achieve the required minimum temperature to address concerns about microbiological growth an additional heat source should be available.
