You have to decide whether you want an instant or storage geyser when you go to the market to purchase the best geyser. Each water heater has its advantages and disadvantages.
As we have seen, the space angle is the ideal size. Let’s now look at power consumption.
Instant heaters are usually purchased for small purposes such as kitchen sinks or washbasins. These places are easy to install geysers. Let’s take a look at the bigger picture.
What is an instant water heater?
We should be able to understand what an instant heater is before we go any further. This appliance provides hot water almost instantly, as the name suggests.
These geysers are expected to have very little storage capacity, typically between 1 and 3 liters. A storage geyser is anything that exceeds 3 liters. This appliance heats water instantaneously, so they have a higher power consumption of between 3 and 4.5 KW.
Heating water takes time
India’s winter temperatures can range from 4C to 21C. Pipes below 4C won’t allow water to flow easily through them as they can become ice.
The ideal conditions are those where the optimum temperature is around 400C and the maximum temperature at 60C.
The instant heater will heat water up to 60C when the temperature of the input water is around 15C. It takes approximately 1 minute to heat water to 40C. It will take 20 seconds if the water temperature is greater than 21C.
Water flow rate
This is an important characteristic. The flow rate of water coming from the taps determines the quality of heat. Normal flow rates are around 3 liters per minute for taps and 8 liters per minute for showers.
If you have a 3-liter instant geyser, then the water will heat up almost immediately after you empty it. Showers have a higher flow rate. This means that you don’t get the water temperature you need to bathe in.
This is a great situation, especially in cities with a water temperature of around 21C. You won’t get continuous hot water in colder areas. It will take some time. It is cold to do this in a bathroom. It can also dissuade even the most determined person.
Where can you find instant water heaters?
These geysers are great for kitchens and washbasins that use less water, as mentioned previously. If you live in India’s southern region, geysers may be able to serve you in bathrooms. The input water temperature is in the range of 20C. It is always a good idea to choose storage water heaters.
There are some drawbacks to instant heaters
The above paragraphs will show that standing loss is at an all-time low. Therefore, power is not wasted. They look amazing from an individual’s perspective. Let’s look at the whole picture.
Instant geysers are responsible for providing instant hot water at the optimum temperature. The power consumption ranges from 3 KW to 4 KW.
Storage geysers use 2 KW of power. Both geysers consume the same power if you heat 15 liters of water. The difference is that instant geysers take a shorter time. They do however put more strain on the system.
Consider the situation in Delhi. The majority of residents in Delhi take a bath between 7 and 9 AM. The grid could fail if each house had an instant geyser.
The storage geysers, however, can balance the equation because they use the same amount of power for a longer time. The demand will not spike suddenly.
Instant geysers can increase the fixed costs. You might be able to save some money, but you can transfer the savings to fixed costs.
