The ECOWAY Lemet 50 litre high quality electric boiler is an EU manufactured unit that is the perfect option as a kitchen or shower water heater.  The ECOWAY has energy label B. With nearly 40 years of manufacturing experience Lemet produces durable, reliable and attractively priced electric water heaters (storage water heaters). Every electric water heater comes with a free 6 bar pressure relief valve. 

The Lemet ECOWAY electric water heater has a digital display and an ECO Function. The ECO function will minimize electrical losses reducing your power consumption significantly. When you connect the water heater it wil monitor your hot water usage and set a program suited to your needs. The DAILY TIME PROGRAMMER allows you to program 3 separate time blocks when you would want hot water available. 

The controller heats up the water heater periodically to 167 °F (75 °C) to eliminate the possibility of legionella. The "DRY STOP" function prevents the heating element from damage in case the tank is empty. Lemet water heaters have been produced in the EU, carry a CE mark and are ErP ready. Warrantee is 2 years.

We can supply one of two pressure relief valves free of charge. Please indicate, which one you prefer by ticking the box at 'Available options' when ordering. The valve with the red lever has a small orifice. You can connect the supplied discharge pipe that orifice to drain of drops of expansion water. The other valve is a WRAS approved pressure relief valve. This WRAS approved valve can only be used together with a WRAS approved check valve and a WRAS approved expansion vessel.

Install the ordered 6 bar pressure relief valve or a 6 bar WRAS or KIWA approved pressure relief valve for the water heater to function properly and to retain your guarantee. 

Using the wrong bar pressure relief valve can cause leakage inside the boiler as the working pressure inside the tank will exceed the maximum tank working pressure of 6 bar. It can also cause excessive calcification inside the tank. Calcification on the heating element slows heat transfer and will cause the heating element to overheat. Overheating weakens the steel and will eventually cause the steel of the heating element to tear resulting in a short circuit.  

We strongly recommend to install a pressure reducing valve if the water pressure is too high (5 bar or more) or if you suffer from fluctuating water pressure. High water pressure and/or fluctuating water pressure often occur in apartment building, flats, farms, older houses and houses and buildings in elevated areas. Install a pressure reducing valve where your mains water supply line enters your premises or right behind the pressure relief valve. Ensure the water pressure is set at 3 bar. Any damage caused by a too high water pressure or fluctuating water pressure will not be covered by the warrantee.


    The water heater was easy to install and set up. Very happy so far with plenty of hot water for my shower.


    I have had the ecoway running for just over a year without problem. And I can say it is indeed much more economical than my previous unit. I liked the service so when I required an under sink water heater I immediately thought of waterheaterstore.


    Great service. Good price. Great product.
