The first and foremost thing which you should know about them is that our old geysers do not simply switch off at one point but their performance gradually drops, noise levels increase, they become too expensive to use, and then it becomes apparent that we will have to pay for electricity more than before due to leakage in your geyser.

Installation & Maintenance Tips for Your New Geyser

  • Have It Properly Fitted: Instant heaters combine plumbing and wiring, so you will need an electrician to do the fitting because a bad installation can render the warranty null and void.
  • See If You Have the Wall and Wiring Capacity: With a 3 kW heater, a lot of electricity will flow, meaning that the circuit must have a dedicated MCB for it and not share the wires with other machines.
  • Do Not Ignore the Pressure Release Valve: This valve must never be obstructed in any way because it is designed to release pressure if necessary.
  • Consider Getting Your Heater Descaled Yearly If Your Water Is Hard: Hard water can cause mineral build-up even on the most durable tanks, which means that an annual check is a good idea.
  • Never Run Your Heater Dry: You should always have the tank full of water before turning on your heater.

FAQ

What capacity water heater is required for 4 people? 

For 4 people a 5-litre instant water heater is generally adequate, provided everyone uses it separately since such water heaters heat water when required, as opposed to water stored in the heaters. However, if there is a requirement to have water simultaneously in two locations or anyone in the house prefers taking a bath to showering, a water heater with more capacity may be required.

Are smart water heaters a good idea for families?

Water heaters with mobile application and programmable features could be useful to prevent keeping the tank warm even when there is no activity in the house, saving you a little bit of energy on standby mode. However, it may or may not be worth it for you depending on your habits, because if you have set shower times then a normal heater will work fine for you.

When Should Your Family Replace Your Water Geyser?

The lifespan of most water geysers is typically 5-10 years for instant geysers and 7-12+ years for storage geysers. However, your water supply will influence the lifespan of your geyser. Increasing costs of energy, poor performance, or rust around the tank are better indicators.

What is the list of most essential safety features of bathroom water heaters? 

The first and foremost safety measure is that it should include the presence of a thermostat with an automatic switch-off function, a pressure relief valve, and an anti-shock or earth leakage-protected body. In addition to this, various supplementary measures, such as an anti-draining valve or double thermal cut-off, increase safety.

Is installing a new water heater a task that can be done by me, or is it something that only a professional should do?

Considering that these systems operate using electricity from the main supply in an environment where there could be water, their installation needs to be done by a licensed electrician or plumber and not as a do-it-yourself project.
