In the description with each article you can check the guarantee period for your product.

If you have a malfunction it is important for us to first establish the cause. Once this has been determined we will send you the replacement part(s). Please contact us by email when you encounter a malfunction and supply us with photos so we can quickly ascertain the cause of the malfunction and whether this falls under the guarantee. Often you can solve the problem yourself, with a bit of help from us.

If you prefer you can also send the water heater back to us,so we can solve the problem for you in our workshop. We do not repair on-site as we do not have installers on the road. We do not install water heaters and cannot be held liable for installation or the dismantling of your water heater. But we shall do our utmost to assist you in solving your problem.

Please note that your guarantee will be void if you have not maintained the heater as indicated by the manufacturer or if you haven’t used the supplied safety relief valve. You can opt to use a KIWA or NSF approved safety relief valve. Always use a 6 bar for Lemet and an 8 bar for Wesen.  Never put an 8 bar safety relief valve on a 6 bar water heater or 6 bar safety relief valve on an 8 bar water heater!

Defects as a result of fluctuating water pressure are also not covered by the guarantee. Sometimes it is advisable to install a pressure reduction valve, on the water mains by the main valve, to protect your water heater from these fluctuations. Especially older buildings, farms and apartment buildings can suffer from fluctuating water pressure.

The guarantee applies exclusively on products supplied by us.

How is an energy label determined?

An energy label classification ranges from A to G with A being the most energy-efficient. The energy label will show the energy consumption of your product. All our products are ErP (Energy related Products) compliant and are subject to energy efficiency requirements.  

Tests are carried out using a standard formation in order to make a fair comparison between the various models of a particular product. If you want to know more on how a formation is built-up and how a test is carried out, please click on the link below.

The indicated energy consumption might differ from your actual consumption as water temperature, ambient temperature, usage time, eg. all play an important role in the actual energy consumption. Please bear in mind that to heat your water the heating element will always use full capacity. A 1500 watt heating element will obviously heat up 50 liters of cold water slower than a 2000 watt heating element. But in the end to heat up that 50 liters of water both the 1500 watt unit and the 2000 watt unit will use the same amount of energy.
