If you’re buying a geyser for the first time, there are a few essential things to keep in mind before installation. Choosing the right model is just the beginning; proper installation ensures safety, performance, and long-term reliability. This guide will help you understand what to check and how to make sure your geyser functions efficiently from day one.
1. Pick the Right Type of Geyser
Before you install anything, choose the right kind of geyser for your needs. For small families or quick water usage, especially in kitchens or bathrooms, instant geysers are ideal. They heat water in seconds, save energy, and don’t take up much wall space. Their compact size also makes them easier to install.
2. Mount It at the Right Height
Your geyser should be fixed at least six feet above the ground. This helps in maintaining water pressure and ensures smooth flow from the tap or shower. It also keeps the appliance safe from splashes or contact with water on the floor. Make sure the wall is strong enough to bear the unit’s weight, especially when it’s filled with water.
3. Check the Power Supply Setup
Every geyser requires a dedicated electrical point. It’s important to use a 16-ampere socket with a proper earthing system and a Miniature Circuit Breaker (MCB). Avoid using extension cords or shared outlets. It’s best to have an electrician inspect your setup before installation to confirm it meets safety requirements.
4. Ensure Correct Pipe Fittings
Proper alignment of inlet and outlet pipes is essential. The cold water pipe should be firmly connected to the inlet, and the hot water outlet should lead smoothly to your tap or shower. Good quality fittings prevent leaks and rust. Avoid plastic pipes; go for durable metal or approved flexible connectors for better results.
5. Ventilation is a Must
Your bathroom or utility area should have enough air flow. Good ventilation keeps the area dry, reduces moisture buildup, and extends the life of your geyser. Avoid installing it in tight, airless corners, especially if it’s near the ceiling or behind a door.
6. Get It Installed by a Professional
It’s strongly recommended to get your geyser installed by a certified technician. Not only does this ensure safety, but it also helps keep your product warranty valid. Many brands, like A.O. Smith, offer expert installation services for their products, making the process easier for first time users.
Looking for an Instant Water Heater?
For those who want a mix of performance and design in their water heater, the MiniBot™ 4.5kW from AO Smith is an excellent choice. It provides instant hot water through a glass coated heating element that ensures efficient heating from the moment you switch it on.
What sets it apart is its stronger construction quality, featuring a tank that’s 2 mm thick, twice the strength of many ordinary instant geysers. It also adds a touch of modern design to your bathroom.
