flow water heaters

The use of flow heaters is one of the cheapest and most comfortable ways to heat water. Water heaters consume electricity only when the water flows, they have energy class A, so they are very energy efficient. Also, the devices allow continuous collection of hot water, which is obtained almost immediately after unscrewing the tap.

In individual (one point) supply systems with hot water, a well-chosen flow heater will provide high comfort for the use of hot water. This type of heaters are characterized by a modern design and a simple and reliable construction.

Flow heaters are selected according to the number and type of water collection points. At home, the most common hot water is the one needed in the bathroom and in the kitchen. If you have a shower in the bathroom with a standard spout, you generally only need 12-15 kW. Keep in mind that if you use a rain shower, you will need a heater with more power and efficiency, adjusted to the needs of rainwater, usually a device with a power output of at least 24 kW or even 27 kW. For a bathtub, use a heater with a minimum of 18 kW.

how water is heated

1. Hot water is on

2. The flow sensor detected a flow of cold water entering

3. The burner lights automatically.

4. The water is instantly heated as it circulates through the heat exchanger and out to the faucet.

Another group of flow-through water heaters are three-phase (high power) heaters. They work as pressure equipment and provide hot water to various points of consumption. The models are models with hydraulic control and more technologically advanced with electronic control. Thanks to the correct programming of the unit, the thermos can operate impulsively, which guarantees a stable water temperature of up to 1°C, which translates into lower energy consumption.

However, flow devices have some limitations: they require proper electrical installation. If proper power allocation cannot be obtained, capacitive heaters must be used.

tank heaters

Electric tank heaters – are mounted above or below the sink – is an optimal solution for single point systems (hot water supply systems).

Installation directly at the water inlet eliminates heat loss associated with hot water flow, and polystyrene insulation prevents stored water from rapidly cooling.
