Hep2O® - Where Not To Use

Where not to use Hep2O®

The Hep2O® system has been designed and tested to meet the requirements of modern heating and water distribution systems. Testing has not been carried out to determine suitability for other purposes and therefore should not be used for instance, in the following applications:

	Conveyance of gas.
	Conveyance of fuel oil.
	In areas contaminated by petroleum and oil derivatives.
	Compressed air.
	Hep2O® is not suitable for use in systems where the water carried in the pipe contains a high concentration of chlorine e.g. swimming pools or decorative water features.
	Hep2O® will not be affected by those levels of chlorine expected in UK water supply (typically less than 0.5ppm). Short term chlorination for disinfection will not have an adverse effect on the system).
	Hep2O® should not be used for primary circuit of a Solar Heating System as temperature cannot be thermostatically controlled.
	Hep2O® is suitable for secondary circulation of these systems.
	Hep2O® should be protected at all times from exposure to direct sunlight and ultra violet light.
	Hep2O® should not be installed in Ringmain Installations.

A ringmain is a water-replenished circulating system maintained at a constant high temperature to provide a permanent source of hot water to its distributing pipes.

Typical locations where ringmain systems are used are hospitals or hotels which distribute constant hot water to wards or rooms at a distance from heat source.

This type of installation is very different from conventional domestic hot water and central heating services. This restriction does not apply to domestic systems operating intermittently at temperatures less than 65°C where a design life of 50 years as detailed in BS 7291 can be expected.
