Frequently Asked Questions
What is the main difference between a geyser and a water heater?
While often used interchangeably, a “geyser” typically refers to a storage-type water heater, meaning it heats and stores a volume of water in a tank. A “water heater” is a broader term that can encompass both storage tank models and tankless (on-demand) systems. The primary distinction lies in the method of heating and storage.
Which is more energy-efficient, a geyser or a tankless water heater?
Tankless water heaters are generally more energy-efficient because they heat water only when it’s needed, eliminating standby heat loss from a storage tank. Storage geysers, while convenient, continuously heat and maintain water temperature, leading to some energy wastage. However, very efficient storage geysers with good insulation can minimize this loss. (See Also: Lansky Vs Work Sharp )
