How does an instant Water heater work?

You may be one of those who have everything electric at home: also hot water heater. You know that the discomfort of a traditional electric heater is that when you finish the water stored in your tank you have to wait. But there are alternatives. We explain how an instantaneous electric heater works so that values ​​if it suits you to get one.

Instant heaters use the energy to raise the water temperature at the time we request it. As its name suggests they provide instantaneously the hot water we need. In front of these are the devices that work by accumulation. 

An instantaneous step heater is more energy efficient than a traditional one because it does not keep a pilot on all the time, which generates less gas emissions to the environment and consequently less pollution, it instantly ignites when a hot water service is required. a spark.

Working of instant electric heater:

They store a specific amount of water and heat it and then offer it. In principle, most instantaneous heaters work with gas and accumulation heaters is usually electric. But also the electrical technology allows imitating the apparatuses that work by gas. Ultimately these devices provide hot water at the time it is requested. This is how an instant electric heater works.

  • When a hot water pipe is turned on around the house, a flow sensor in the Instant Heater detects movement in the water and automatically activates providing instant hot water. The water passes through several electrical modules that heat the water and goes out to the desired temperature that is controlled on the digital screen. As these Instant Heaters offer the same flow in seconds as conventional water heaters, they need high-powered electrical elements. In more modern units like the Tempera there is a range of integrated sensors and microprocessors that control a precise temperature of output continuously.
  • When the hot water pipe closes the flow goes down and the unit is completely turned off, without any energy consumption until hot water is needed again.
  • The instantaneous type gas heater is constituted by a burner, whose flame takes place in a metal chamber. This is inserted in a series of turns of copper tube into which circulates the water that comes from the installation of the house. When the hot water tap of any device powered by the heater is operated, the flow of water through the tube causes a pressure variation that drives a valve inside the heater, thus causing the gas to ignite.
  • Normally, the ignition of the pilot flame is usually done by means of a piezoelectric system that consists in that once the gas spigot is opened, the push-button is pressed one or more times until the flame is produced. After a few seconds, the button can be released, keeping the pilot flame on. In this way, the thermos will already be able to act so that the burner ignites if the water flow is opened.
  • As the water heats up as it passes through the heater, it must be properly selected according to the number of services to be used; otherwise the hot water supply will not be adequate.

In short you should know that with an instant electric heater you save energy as long as there are not many household members. Its advantage is that it heats water only when requested and not all the time, as is the case with accumulation devices. If you decide to install a device with these characteristics make sure you have the right power contracted with your electric company. Find out in the store where you purchased the product.
