Instant Geyser VS Storage Geyser – Buying Guide

When we take a look at any comparison of electric water heaters, it is likely that we will find two different types of products which are instant water heaters and storage water heaters.

Operating power

An important aspect when looking for an electric water heater of economic cost and adequate heating capacity is the operating power.

A power that must be in line with both the type of product chosen and its output capacity.

Starting with the instant geyser, they need a high power to heat the water, since it passes quickly through them.

In general, this power starts at 2.5 or 3 kilowatts of the simplest models and up to 10 or 12 kilowatts of the professional models and has high water output.

So it is convenient to adjust the power for our specific use so that the electricity bill does not end up emptying our pockets.

In the case of a storage geyser, the power depends on the capacity of the tank. However, for 100 liters of capacity, it is usual for this power to be about 1,500 watts and it increases in some models to 2,000 watts when the capacity is greater.

The advantage is that most of these models are that they include a thermostat which makes it easy to choose the water outlet temperature.

Heater capacity

In these tips, we cannot ignore the capacity offered by the hot water heater, and we must bear in mind it so that it adjusts to the specific needs of our home.

In instant models, the capacity is measured in liters per minute of hot water that the product can generate per minute. An aspect that depends on electrical power.

With the additional fact that these types of products reduce the amount of water discharged with respect to the inflow through their own operating system.

As for the storage geyser, the capacity is what the tanks of the different products that we can see offer us. In this case, it will be the size of our family that makes the difference.

For a 1 or 2-member household, models of about 50 or 60 liters are usually sufficient and should rise to around 100 liters for 3, 4, or 5-member households.

And if this figure is exceeded or if they are used in high demand environments then the figures can go up to 120 or 150 liters.

Electricity Consumed By Both Heaters

The instant geysers deliver instant warm water in optimal temperatures instantly. The energy consumption is within the range of 3 KW to 4.5 KW. The instant geyser when used for longer hours takes up more power.

The storage geysers have two KW of power. If you warm 1-5 liters of water, then the geysers will have the exact same quantity of power. The storage geyser uses less power because it heats water in 5 minutes and not instantly.

The only difference is that instant geysers require less time. But they put more load on the computer system.
