What is an instant water heater?
Instant water heater is a type of water heater that heats water in real time. It only heats the water that passes through it at that moment. There is no hot water storage tank. This has many advantages, such as energy saving, as only the water that is used is heated, as well as longer lifespan, as there is no water tank and accumulation of salts in the heating element and other components.
It operates with liquid gas (gas), and no electrical installation is required.
How It Works
The instant water heater has a cold water inlet pipe, which passes through the resistance, heats up, and comes out in the hot water outlet pipe. A necessary condition for the instant water heater to initially operate is the pressure of the cold water inlet not to be too low.
The water temperature is regulated by a thermostat, so as not to exceed an upper limit. The temperatures reached by the hot water are pre-set so that someone can use the hot water directly, without the need for mixing with cold water.
The maximum temperature that can be reached for hot water production is 65 °C, while the maximum water flow rate reaches up to 11.2 liters per minute. As an indication, 38-42 °C degrees are the standard for shower use.
Advantages of instant water heaters compared to traditional electric water heaters
- It is small in size and does not take up much space.
- There is no energy loss, as only the water that is being used is heated at that moment. Therefore, there is savings on the electricity bill. In a traditional water heater, the unused hot water goes to waste.
- The hot water used in the instant water heater is used as is, without mixing with cold water, as in a traditional water heater. This also saves water, in addition to electricity.
- There is no need to wait for the water to heat up. As soon as we turn on the faucet, hot water starts running in a few seconds. A traditional water heater takes a few minutes, depending on its size.
- The hot water never runs out. As long as we have the faucet open, we will have hot water.

Reviews
I have already installed 2 of the same (because I am a plumber). As mentioned in the other review, yes, the water will not reach 65°C even if no one takes a bath there.. it has reached up to 55°C and if you insist too much, it shuts off for safety reasons. You need to find the right setting for the water so that it has the correct pressure.. Yes, it does require a boiler plus at least 30€ and you will also need around another 30-40€ for gas regulators and filters so that the installation is correct and in terms of LPG. It is indeed very economical, definitely one bottle lasts a month or more. For a family of 3 people. The instructions are so-so, but if you know, it's okay. The batteries lasted 3 months in one of them... very economical and immediate hot water

Did you find this review helpful?Quite a good solution now with the cold, don't expect it to reach 65 degrees, but it easily covers your bath even though mine has only gone up to 55 degrees. With a lot of cold, it goes down to 45 degrees. I want a bottle for the month for 16 euros, but keep in mind that I use it for bathing, washing hands, dishes, basically everything with hot water. It should be installed high up because if you set it up to not use any cold water, you won't have enough pressure to take a bath. Also, batteries need to be replaced every month and cost about 30 euros. Of course, you will need to make a hole in a wall for the installation. The instructions are so and so, and of course, if you place it in a very closed space, you will need two more air vents and no fan because it requires enough oxygen. The faucet should face upwards, otherwise, it will turn off.
EDIT: ONLY BRING AN AUTHORIZED TECHNICIAN BECAUSE OTHERWISE YOU WILL END UP LIKE ME, WITH SERIOUS DAMAGE, AND NOW I'M RUNNING
