Product description
WetAir · MWH1-50L
50 litres with 1 °C adjustment
MWH1-50L is a 50-litre storage water heater with a 1500 W enamelled wet heating element. The digital panel adjusts the setting in 1 °C steps, so you can select a temperature rather than choose from a small set of fixed presets.

How it works
From cold water to a stored hot supply
In MWH1-50L, water heats in a 50-litre tank, ready to be drawn through the connected water system.
The tank fills
Cold water enters the storage tank. The tank must be completely full before the first electrical switch-on.
The element transfers heat
The enamelled wet heating element is in direct contact with the water and transfers heat to it.
The temperature is maintained
The controls call for heat to maintain the selected temperature. As hot water is drawn off, cold water enters the tank and the heating cycle repeats.
The resultStorage separates heating from the moment of use: a hot-water supply is prepared first, then drawn off.
Simplified diagram: the wet element is directly immersed in water. Service the magnesium anode as directed in the manual.
Capacity for your use
The 50-litre tank gives you a stored hot-water supply without moving up to the series’ 80-litre version. Match capacity to your use: once the stored supply is drawn off, the water needs time to reheat.
Temperature on the panel
A 1 °C step gives fine adjustment on the digital panel. ECO maintains 55 °C; the maximum heating temperature is 75 °C.
Access for maintenance
Leave space around the connections for inspection and service. Overheat protection and the IPX4 rating complement the design; they do not remove the need for correct installation.
First start and everyday use
Arrange professional connection
Have installation and electrical and water connections carried out according to the manual. Leave access to the panel and service connections.
Fill before heating
Never energise an empty tank. Once it has been filled correctly, select a temperature and allow it to heat.
Check the water before contact
Hot water can scald. Mix it carefully with cold water at the tap and check the temperature before use.
Your questions answered
What temperature does ECO use?
55 °C. This model’s maximum setting is 75 °C.
Does it work like an instantaneous water heater?
No. This is a 50-litre storage model; reheating takes time after the hot-water supply has been used.
