Yes, Gas geysers are perfectly safe, just as long as they are installed properly. Modern gas geysers have many safety features that make them quite safe.
For example, if there is a malfunction with your gas regulator and it gave out more gas than it should, and there was an increased amount of heat in the gas geyser, the gas geyser has temperature sensors in for the air temperature exiting the unit, if the temperature is too high, it will stop supplying gas to the burners. If that were to fail there is a second water temperature sensor, if the outgoing water temperature is too high it will stop supplying gas to the burner so you don’t burn your skin.
Get a registered Installer
However, there is no safety device if there is an external gas leak, so that is why it is important for the gas geyser to be installed by a registered gas installer. You need to exercise sound judgment when choosing a gas installer. Just because they are registered does not mean they automatically do safe installations. That being said, most registered installers will do safe installations. Just keep an eye out 👀.
- 9 times of 10 a gas geyser should be installed outside. But if it is installed inside, the exhaust gasses need to be piped/vented to the outside. This is extremely important.
- Your gas installation needs to be inspected every 12 months to ensure there are no leaks and that the gas appliance and installation are in working order.
