Electric heaters for running water
The water heater has a lot of advantages in comparison with the cumulative:
- Compactness . Due to its small size, a flowing mini water heater can easily be placed anywhere in the bathroom or in the kitchen.
- The ability to instantly heat water . Cold water, entering inside, passes through a flask and a heating element - a ten. Due to the high power of the tan, the water reaches a temperature of 45-60 ° C. The water heats up very quickly, unlike the storage heater, which heats the water for a certain period of time.
- Possibility to receive hot water in any quantity . This is an undoubted plus in comparison with a storage heater, where the amount of water is limited by the volume of the tank.
- Simplicity in maintenance in comparison with the accumulator heater in which it is required to clear regularly from a scum magnesium anode.
But the flow heater has its drawbacks:
- Often there is a need to connect to a three-phase power supply system. The use of a heater only in order to wash the dishes requires a power of 4-6 kW. For comfortable adoption
the shower already needs a power of 10-14 kW. Therefore, installing a flow-through heater often requires the isolation of a separate cable and machine on the electrical panel. - Possibility to operate only one water point. The device is difficult to cope immediately with several hot water sampling points. Therefore, you can install a flowing water heater only on one tap or connect it to a shower unit.
