Geysers are one of the most common electrical appliances used in homes. Water heaters last longer, save energy and are safe compared to traditional immersion rods. Various types of water heaters are available with rapidly advancing technology, conventional storage and instant water heaters. While instant geysers offer quick heating, storage water heaters are ideal for families because of their large storage capacity. Selecting the perfect geyser is a challenging task and depends on the size of the bathroom, family size, hot water usage, warranty, budget and energy efficiency. 

Proper geyser maintenance is needed if you want the water heater to last its lifespan and more. For regular maintenance, it is best that expert technicians service or repair your geyser so that it lasts longer.
