Faulty geyser no hot water

Faulty geyser no hot water

Faulty geyser no hot water is a common issue which we deal with daily. The various reason causes a faulty geyser and no matter what the issue we have the solution. Our teams drafted lit of some of the more common issues and we have also included some tips on how to care for your geyser. Key to the preservation of this central part of your domestic or commercial plumbing installation is what we love to share with clients. Our beliefs revolve around offering a valued service of not only delivering a service but really caring for our clients. To start off let’s first look at some of the typical failures in geysers.

Faulty thermostat causing a faulty geyser

A faulty thermostat can cause very interesting issues. Upon replacement of the thermostat, the element will also be replaced as these are the two critical items that ensure proper heating of your geyser. The different issues caused by a faulty thermostat are as follows:

Thermostat stuck on the on position

The thermostat stuck on the on position causes the temperature of the water inside the geyser to boil. Thus, a lot of water will be dumped by the T&P valve. Resulting in boiling water being noticed outside your house or office. If the T&P valve is faulty the geyser will release air through the Vacuum Breakers fitted to the inlet and outlet of your geyser. If you don’t have Vacuum Breakers fitted, or they are faulty the geyser can explode. However, in a normal case scenario, they just burst.

Thermostat stuck on the off position causing no hot water

A thermostat stuck on the off will simply cause the geyser not to heat up any water. Obviously, this is the safest failure and can not cause any harm. We test and replace faulty thermostats regularly and is a very common issue.

Faulty geyser Element

Geyser element failure

Geyser element failure will simply cause the geyser not to produce any hot water at all. Various reasons cause total failure of the element and deserve some mentioning. The various reasons are as follows:

Overheating of the element

Overheating of the element is caused by a geyser that is running low on water and the thermostat switches the geyser to the on position. Resulting in the element sustaining permanent damage as it burns out. The interesting aspect here is when the element does not burn out completely. Thus, inside the element, a connection is still active. The result is the element’s life span is decreased and thus will fail prematurely. To curb this effect IOPSA has laid new installation rules that prevent the geyser from running low on water when the water supply is switched off by the municipality. When we visit your premises we will bring this fact to your attention if your geyser does not comply.

Age of element

Age of element does play a role and we have seen so many ancient geysers that have failed due to age. When your geyser has worked flawlessly for the past 15 or 20 years it is to be expected. The element over the years develops hairline cracks as it heats up and cools down. Thus, eventually moisture penetrates the element out of the shield. Causing small shorts inside the element that causes excessive heat to be produced by portions of the geyser element that is not exposed to the moisture. The result is overheating of some portions of the element. Causing it to burn the resistive section of the unexposed element.

Element failure due to corrosion and salt deposits on the element

Element failure due to corrosion and salt deposits on the element is typical and one of the leading reasons why elements fail. Due to the number of chemicals added to drinking water. And the neglect of property owners to regularly service their geysers. We see large numbers of failures. The water supply is high in mineral and chemical content. Thus, it causes a deposit on the element of the geyser. As the element now struggles to heat up the water it is forced to be switched on for longer periods of time. Thus, diminishing its life span. If the geyser is regularly serviced every second year by replacing the self-sacrificing anode and in doing so prolonging the life of the element.

No, it does not as your geyser will only loose 10⁰Celsius in a 24 hour cycle.
