Domestic hot water


Using precious drinking water

Water is essential for life and subject to the highest quality requirements. This also applies to the technology that controls and safeguards the domestic hot water supply. Circulators from Wilo are the solution for all who have the most exacting demands on materials, operation and convenience.

Water is one of the most important resources worldwide. And this is what makes the sustainable handling of this resource so important. Over 70 percent of the earth’s surface is covered by water, but only a fraction of this amount is entirely suitable for use as drinking water. As the water used for drinking water is extracted as 70 percent groundwater and spring water.

Hot-water convenience that pays off

Lack of circulation or too long a pipe distance are often the reasons why cold water first comes out the tap and the water temperature only gradually rises. Until the water has been heated to the desired temperature, several litres of drinking water flow down the drain. In order to curb wastage of drinking water in the home, it is worth getting hold of a circulator. Reliable domestic hot water supply faces a challenge in commercial use as well. Circulators from Wilo satisfy the most exacting quality requirements when handling water, the substance that is essential for life. They ensure trouble-free operation and are particularly efficient, which means they save electricity. Intelligent technology can do both: it provides hot water quickly, while saving energy and resources at the same time.

The water quality of drinking water

The water quality is normally legally regulated and controlled by directives, various guidelines, recommendations and regulations. The taste of drinking water varies in many regions due to the differing minerals that are dissolved in the water from the ground and rock substrates the water passes through. Healthy, clean drinking water is colourless and clear as well as neutral in taste, odourless and safe.

The drinking water supply process is made up of water extraction, treatment and distribution. During the complete drinking water supply process chain, the preservation of contamination barriers is enormously important in order to keep the need for technical treatment to a bare minimum. Contamination due to material, substances or legionella does not occur in distribution systems that have been installed in a proper manner and which are regularly and correctly maintained and operated. Therefore the decisive component for high drinking water quality is excellent management of the systems, which is the responsibility of water utilities and building owners or operators. To meet these challenges, Wilo offers tailored, high-quality solutions for a drinking water supply that you can rely on.

Facilitating water supply

Especially in older buildings, the problem often occurs that the water pressure in the water pipes is too low. Raised water pressure is necessary to ensure correct usage of all devices. Wilo has an extremely wide range of pump system products that can meet these challenges. Part of this being, of course, a wide model range for drinking water supply. Our products promise excellent water quality, which fulfils all regulations. The expertise we have gained over many years shows that whether the water comes from the surface or from ground water has no impact on the quality.

Based on our extensive experience with building services projects, you can rely on our support, both at the design stage and during the implementation phase of your projects.

The correct drinking water installation

The water utility companies guarantee the water supply quality up to your building installation. However, the building owners or operators are responsible for the continued quality of the water until it emerges from the tap and reaches the end consumer. In order to fulfil this obligation and comply with the prescribed limit values, the carefully considered selection and installation of pipes and pumps is extremely important.

Professional installation

The professional installation of the pump system by a certified installer or contractor can avoid a wide range of problems, which protects your drinking water and prevents contamination. The installation contractor should only use products with a mark of conformity from an accredited certification body for the performance of their services. You are on the safe side with products from Wilo.

Our tips

  • Work on your drinking water installation should only be carried out by specialist contractors.
  • Treating water in a respectful and sustainable manner saves both money and energy.
  • You should avoid disposing of poisonous substances or waste via the sewer system in order to conserve and maintain our drinking water resources.
  • Getting a dripping tap repaired is not just relief for your nerves, it also lightens the load on your wallet and the environment. A dripping tap can waste over 1,000 litres of drinking water per annum.
  • If water stands in the pipes for a long period, the resulting stagnant water can still easily be used for watering plants.
