Difference between Tankless water heaters and Instant water heaters
Tankless water heaters, also known as on-demand water heaters, are a popular alternative to traditional storage tank water heaters. They work by heating water only as it is needed, rather than constantly maintaining a supply of hot water in a storage tank. Tankless water heaters have been gaining popularity in recent years due to their many benefits over traditional water heaters with storage tanks. As more people become aware of the energy and cost savings that tankless water heaters can offer, they are increasingly being seen as an emerging technology in the world of home appliances.
Tankless water heaters are usually compared to Instant water heaters. While they both provide hot water on demand, there are some key differences between the two:
Size : Tankless water heaters are typically smaller in size and are sleeker than traditional water heaters with a storage tank making them great space -savers. They are ideal for homes with limited space & small bathrooms. They can be easily fitted inside the bathroom and above false ceilings. Tankless water heaters are smaller than Instant water heaters of similar wattage. They can also be fitted in small enclosures or below the sink in horizontal or inverted configurations.
Capacity: Instant water heaters have a small tank of either 1 ltr or 3 ltr capacity and are limited by their wattage of 3kw or 4.5 kw. So they provide hot water with a low flow rate. Whereas tankless water heaters, do not have a tank and have higher wattages, starting from 5 kw upto 24 kw and can provide hot water for an entire household.
Heating Process: Instant water heaters heat water as it flows through the unit, using electricity . Tankless water heaters also heat water on demand, but they use a heat exchanger to do so. They circulate water through the heat exchanger, which is heated by electricity, to provide hot water.
Energy Efficiency: Tankless water heaters are generally more energy-efficient than instant water heaters, as they only heat water as needed, whereas in instant water heaters additional energy is required to heat the volume of water inside the small tank.
Cost: Instant water heaters are typically less expensive than tankless water heaters, but they are also less powerful and can only provide hot water to one fixture with low to medium rate of flow. Tankless water heaters are more expensive but are designed for high usage and supply to multiple points - shower, kitchen, bath etc. making them a more practical choice for larger households.
Operation: Instant water heaters have small capacity tanks with an element fitted that operate based on a thermostat which switches ON/OFF the heating based on set temperature. Tankless water heaters on the other hand operate on the Flow based technology. The unit switches ON when it senses the water flow and switches OFF when there is no water flow.
Maintenance: Since Instant water heaters have a small storage tank and
element, it requires maintenance depending on the water quality of your area. Tankless water heaters maintenance is hassle-free as there will not be sediment formation or scale deposits on the element.
Output: In Instant water heaters the output is average and suitable for single point usage. Tankless water heaters are ideal for modern homes where shower panels, rain showers are installed. They provide super hot water with higher output and with good rates of flow suitable for such usage.
Time to heat the water: The time taken to heat the water in Tankless water heater is instantaneous as soon as the tap is opened. Whereas in Instant water heaters, the water in the small tank has to be heated up first; so hot water can take a little longer to start flowing from the tap.
Safety: Tankless water heaters are very safe to use as they operate based on flow based technology. The element switches ON/OFF based on the water flow. In Instant water heaters on the other hand, there is the possibility of dry heating of the element if there is no water in the tank.
Installation Requirements: For Instant water heaters the requirements for installation are very simple and can be fit either in the kitchen or bathroom and requires just the basic electrical requirements. But in the case of the Tankless water heaters, they may require thicker wiring due to the higher wattage –between 3 x 2.5 mm2 and 4 x 6 mm2 depending on the model selected. A circuit breaker between 25 amps and 40 amps, may be required. In Mumbai, this wiring requirement is almost standard in most buildings or quite simple to get done; so tankless water heaters can be easily installed after a proper site inspection by a qualified installer & electrician. Tankless water heaters therefore are being recommended by most Architects and consultants for modern homes.
Overall, both instant water heaters and tankless water heaters provide hot water on demand and can be a good choice depending on your specific needs.
