Forget about dripping taps
Your home is the place where you feel most comfortable. That’s why we focus on maximum efficiency and comfort for your home when developing our products. Comfort through technology. Take our small water heaters in the SNU SLi series as an example, which come with anti-drip and thermostop.
The anti-drip function was developed by us and delivers what its name promises. It ensures that the tap does not drip when water is being heated in the small water heater. You will save water and prevent annoying limescale deposits on the tap and washbasin. The thermostop function prevents the tap itself from heating up. This saves energy and avoids unnecessary costs for you.Get the answers to your DHW cylinder questions
Would you like to have a DHW cylinder in your home but still have some questions? We’re here to help! Here is an overview of our frequently asked questions.
How large should a DHW cylinder be?
Do you need hot water quickly? Then a DHW cylinder is the perfect solution for you. We differentiate between small water heaters, wall mounted cylinders and floor mounted cylinders. Your individual requirements determine the size of appliance you require. You can find several examples at the top on the page under “Good reasons to enjoy your home comforts”.
How does a DHW cylinder work?
A conventional “electric storage water heater” heats the water with the help of a heating element/heater rod. This is traditionally a tubular heater, similar to those used in electric kettles. The appliance stores the energy in the form of heated water. The domestic hot water is heated to the temperature that you have set. Temperatures of up to 85 °C can be set, resulting in a very high volume of mixed water being available for showering, bathing or other purposes. (Mixed water = water at 40 °C). After hot water has been drawn off, the DHW cylinder heats the water again either directly (single circuit operation) or at night (dual circuit operation) when tariffs are lower, depending on the operating mode.
What is the purpose of a DHW cylinder?
With small water heaters, we differentiate between non-pressurised and pressurised appliances. Non-pressurised DHW cylinders are suitable for supplying one individual draw-off point. These appliances can only be operated with a non-pressurised tap. They are used in detached houses and apartment buildings, sports facilities and commercial kitchens.
Pressurised DHW cylinders supply one or more draw-off points. They can be operated with a commercially available pressure tap fitting. For example in hotels, hostels and barracks.
Wall mounted cylinders can store more water and are usually installed in the bathroom above the bath tub.
Floor mounted cylinders have an even greater storage capacity and can hold up to 1000 litres of hot water. You can use them to supply entire apartment buildings, no matter what kind of heating system is installed.
What all DHW cylinders have in common is that they store hot water with little standby energy, so that large quantities of hot water are available to you quickly.Downloads
