When does a Geyser become a Boiler

[GCE]

Hi

Had an interesting question that has me thinking, trying to decide which way is correct.

On a hostel type environment they have installed a central hot water system with a +/- 500L tank with 3 phase elements in it.
The consultants are calling it a boiler and saying that it does not need to be on earth leakage unit.
If they call it a Boiler it may not need an earth leakage at 30mA but it will need a Adit relay.

The question I am asking is , when does a Geyser become a Boiler according to SANS 10142-1
Anybody come across the dilemma ?

What's an Adit relay first of all? This is interesting indeed [emoji16]

6.16.2 Water heaters
NOTE Water heaters include geysers, instantaneous water heaters including units
for boiling water, heat pumps, solar systems, induction water heaters and the like (see
also 6.16.1). electrode water heaters, steam generators and boilers are not included
(refer to 6.16.7)

From an engineering perspective, the objective of a boiler is to bring the liquid to boiling point...
A geyser surely is supposed to stop heating well short of boiling point.

BTW - there's a typo. It should be Electrode (capital E) as it is the first word in the sentence.

You're not SANAS

Been meaning to come back and post the findings on the original question I posed

According to the regulations - "Pressure Equipment Regulations of 15 July 2009 " The description pasted below is excluded from the pressure regulation .

2(3h) fixed electrical hot-water storage container of water capacity
from 15 litres to 450 litres operating at a maximum pressure of
600 kPa manufactured to the requirements of SANS 151, which
shall be installed in accordance with the requirements of SANS
10254

If your consultant decides that his so called boiler falls outside of the above scope and therefore does not need earth leakage unit then he will need to comply to the balance of the Pressure regulations and have the unit registered with the DOL and have the unit pressure tested and inspected on a regular basis , every 36 months. The unit will still need to comply with SANS 10142-1 and have a Earth leakage relay at 10% of rated current.

Would think it is more cost effective in the short and long run to call it a geyser and be finished with it.
