What is an instant water heater?

The 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 savings, since only the water that is used is heated, and longer lifespan, as there is no water tank and no accumulation of salts on the resistance and other components.

It operates with electricity and is single-phase.

How It Works

The instant water heater has a cold water inlet pipe, which passes through the resistance, heats up, and exits through the hot water outlet pipe. A necessary condition for the instant water heater to initially function is the pressure of the incoming cold water should not be too low.

The water temperature is regulated by a thermostat, so it does not exceed a maximum value. The temperatures reached by the hot water are preset so that one can use the hot water directly, without the need to mix it with cold water.

The maximum temperature that can be reached for hot water production is 60 °C, while the maximum water flow rate reaches up to 8 liters per minute. Indicatively, 38-42 °C is the standard for shower use.

Advantages of an instant water heater compared to a classic electric water heater

  • It is small in size and does not take up much space.
  • There are no energy losses, as only the water being used at that moment is heated. Therefore, we save on the electricity bill. In a traditional water heater, the hot water that is not used goes to waste.
  • The hot water used in the instant water heater is used as is, without mixing with cold, as happens in a traditional water heater. Thus, we also save water, in addition to electricity.
  • There is no need to wait for the water to heat up. As soon as we turn on the tap, hot water flows in a few seconds. The traditional water heater takes a few minutes, depending on its size.
  • The hot water never runs out. As long as we have the tap open, we will have hot water.

I have it for two months and it works perfectly! I installed it without any difficulty. Let's see how it will work in the winter.......
I bought two more of them to have them as backup for both houses.
Until today - 30/12/22 - I take a normal shower... you just need to reduce the water flow in order for it to heat up quickly. So its use is satisfactory. I recommend it as a good and economical solution.
After a year and a half of use, (27-3-24) I can say that it has fully met my needs.... even during heavy winter conditions!

Poor quality materials. All plastic. Two rubber bands were missing. The connection between the heater and the phone broke when tightened, and it was impossible to find a pipe of the same size, neither 1/2'' nor 3/4''. After some tinkering and improvisation, the hot water pipe opened (tore) during the second use. However, while it was working, it heated the water.

    With this bathroom water heater, you can take a bath much more easily than you would with another one that is a faucet with a shower due to the difference in pressure, regardless of what the devices say! What I don't like is that with all small-sized water heaters, when the flow is greater, cold water starts to come because it can't heat up at a high flow (logical due to size) and nothing else. Other than that, with this one, taking a bath is easier than with others, but not like with the water heater where you control the flow independently of the hot water! I clarify this because some may get confused!

    For me, in my opinion, it is not suitable neither for winter nor for summer. In winter, you open it as little as possible and it cannot exceed 32 degrees, and in summer you open it all the way and it does not drop below 45 degrees. The bathroom as a space usually has a temperature of 28 degrees before it is used, winter - summer. In addition, it is very poorly constructed and the water inlet and outlet, as well as the phone cord, are very bad. Apart from being quite short, you cannot replace it due to the threading in the screwing that does not fit with any other and requires a patent

    I bought the product for use with a bidet phone. The connection to the phone is made in unrelated, rather mediocre turns and I had to improvise. The water regulator broke in a month and I put in a valve. At some point, it turned on by itself and luckily I happened to be nearby and unplugged it. I opened it up and connected the contacts, so I operate it with a power switch. While it works, the water temperature is not stable even with constant pressure. It is sufficient for the bidet, but I don't think it's suitable for bathing. I should note that I bought it because it was the only one I found in 3.5kW that was acceptable for short-term use with a 1.5mm cable I had in the installation, otherwise I would have bought something of higher quality.

    Very good. It provides hot water... but what they don't mention is that the temperature adjustment depends on the water flow. In other words, in order to take a hot bath (above 40 degrees), you will have to greatly reduce the amount of water. The temperature regulator... essentially functions as a water flow regulator. Overall, though, I am very satisfied. My family uses it due to a malfunction in our solar water heater.

    It never worked properly, it doesn't adjust the water temperature but the pressure, it tripped the circuit breaker (the washing machine works fine on the same outlet...)
    I returned it and got my money back immediately.

    The water cannot be heated above 32 degrees... and we still have hot days. What will it do in the cold? You can't take a bath with this temperature. Useless purchase.

    Tested only in the summer so far, but with enough cold tap water supply. In the few days that I have used it, it works exceptionally well. It requires a little attention because the hydraulic connections are plastic. For €30, I don't think there is anything better.

    For summer when the demands are low, it raises the temperature a few degrees which is sufficient. For winter, I consider it inadequate to take a bath. Otherwise, it seems to have good construction.
