Instant geysers must have thermal cut-off, pressure release valve and overheat protection. If any of these features is missing then the risk increases.

Secure models may be a bit expensive. But they prove to be better in the long run. Quality of tank and internal parts. Models with stainless steel or copper chambers are durable and heat water quickly. Cheap models look good in the beginning but in the long run, the chances of frequent breakdowns increase.

Finally, pay attention to installation and warranty. It is important to get the installation of instant geyser done by a proper technician. Because wrong fitting can increase the problems of both electricity and water. Along with this, choose a model with at least two years warranty so that there is no problem later.
