Hot Water Systems

Hot Water Systems

Hot water systems can be described as tanks, cylinders or reservoirs that hold water which is then heated either by an electric element, by gas, or the sun (solar energy collector) or any other heat source.

Electrical Geysers

In years gone by, low-pressure roof tank fed, vented hot water systems were common; then in the 1970’s manufacturers were working hard at developing mains-fed closed pressurized systems in which steel tank hot water cylinders could be capable of handling higher pressures.  The industry settled on 100Kpa and 200Kpa for copper tank geysers and 400Kpa for steel tank geysers.

During this time, domestic pressure geysers started exploding, the cause was soon identified as electrical control failure, causing the water to superheat with the potential to explode.  At the time it was mistakenly thought the controls and protection built into the thermostat and electrical circuitry would be adequate.  The solution was found by adopting the safety practice used in America and Europe, resulting in the first mechanical temperature and pressure safety valves, which would open and relive water from the geyser before it reached boiling point and so prevent an explosion.

From the above it was clean an industry standard for geyser installations was required, to ensure that these safety components were correctly installed.  So it was at the time that the SABS technical committee developed the forerunner of what is now SANS 10254, which is a compulsary national standard for the installation of electrical geysers.

The pressure ratings are easily matched with the used of the colour coding requirements in SANS 198:  Functional-control valves and safety valves for domestic hot and cold water systems

All valves must have the same rating, so the temperature and pressure safety valve (TPS or T&P) valve must be same rating as the Pressure Control Valve (PCV). The hot water cylinder can obviously never be a lover pressure rating than the matched control and safety valve
