Hygiene and ease of use



SYSTEM Fittings

Design Consistency

HEWI system fittings are the definition of quality. They are well thought-out right down to the smallest detail and are characterised by a high levels of operating convenience, easy cleaning, hygienic design, safe use and ease of maintenance. They are designed to be used in highly frequented public sanitary rooms. HEWI offers a selection of child-friendly fittings especially for smaller users. HEWI system design allows a uniquely consistent design from the door to the sanitary room and HEWI system fittings follow this principle and complement the existing portfolio.

They form a cohesive and complimentary design unit with all HEWI sanitary accessories, accessible products, washbasins and fittings. DVGW certification and compliance with DIN 15091 means that HEWI system fittings always meet the highest quality standards. The WELL efficiency label also demonstrates how resource-frugal HEWI system fittings are.

Intelligent functions

Refined technology down to the smallest detail

Carefully selected, high quality materials make long-lasting fittings and offer increased safety for drinking water quality. Mature technology and the exclusive use of high-quality components from established manufacturers are the essentials for lasting reliability. Outstanding quality is achieved once every detail has been well thought out and provides tangible benefits. This is clearly the case with HEWI system fittings, and clearly demonstrated by the number of technical features that distinguish each individual HEWI fitting from the ordinary.

Protected cartridge

The lower edge of the lever completely covers the cartridge cap. This protects the inside from contamination. In addition, the closed shape protects the cartridge from damage caused by cleaning agents for example.

Hygienic design

By deliberately dispensing with a tie-rod hole and using a closed fitting body, hygiene is significantly increased. This makes the body of the fitting extremely easy to clean.

HEWI Mini thermostat

The HEWI Mini thermostat regulates and limits the maximum outlet temperature of the water. For example, the water flow stops automatically if the cold water supply fails, which means the user cannot scald themselves. This naturally makes HEWI system fittings even safer to use.

Easy assembly

Pre-assembled components and clear markings on the connection hoses make installation a breeze. The 450 mm long connection hoses from Neoperls are made of stainless steel mesh and have coloured, interwoven threads for simple hot/cold identification.

One design language - two methods of operation

Manual and sensor-controlled fittings

Depending on the specific requirement, some fittings are available as either a manually operated single-lever washbasin mixer or as a sensor-controlled fitting. Functionality and methods of operation differ in these two variants - whilst their design language has a single voice.


Intuitive operability

Many years of experience have made HEWI an expert in accessibility. Since then, universal design has been a constant part of our lives at HEWI. Our system fittings have been developed with accessibility in mind. Together with our washbasins they have been designed to form a complete, functional accessible unit.

High-contrast design

Large radii prevent sharp edges that could be bumped against. The operation of HEWI system fittings is intuitive: be it through clear, easily understood hot/cold markings or high contrast control levers, or through contactless sensors which require no effort to operate.

AQ 800 K single-lever washbasin mixer

The coloured handle element can be specified with a high contrast grip - there are 16 HEWI colours to choose from. It is made of a polyamide material and is pleasant to grip.

AQ 800 Single lever washbasin mixer

The single-lever washbasin mixers are equipped with an open operating lever. This allows them to be operated with just one finger making them easier to use for people with motor impairment.

Comfort and safety in the shower

Shower thermostats

Shower thermostats offer special comfort. Not only can the amount of water be precisely adjusted via a control on the side. The desired temperature is selected via a separate control. A hot water lock with safety button limits the water temperature to 38 °C. Warmer water can only be set when the hot water lock is released using the safety button. The Flühs thermostatic cartridge immediately compensates for changes in temperature and water pressure so that the temperature remains constant, thus increasing the user's safety.

HEWI shower thermostats are made of solid brass. This ensures particularly long-lasting quality and reliability. The brass body and the Neoperl backflow valves can withstand high internal pressures making HEWI shower thermostats particularly suitable for thermal disinfection. Backflow valves allow water to flow in only one direction - which effectively protects water pipes from contamination and prevents germ formation.

Additional protection to guard against the fitting body getting too hot is provided by the HEWI SAFE TOUCH shower thermostat. This technology allows the body of the fitting to be cooled on the inside, keeping the surface of the shower thermostat at a pleasant temperature so that touching it cannot lead to burns. Fluctuations in temperature and water pressure are immediately compensated for by the Flühs thermostatic cartridge, allowing the water temperature to be kept constant. The shower thermostat also has a hot water lock to prevent accidental scalding.

The thermostat cartridge inside the thermostat body compensates for temperature and water pressure fluctuations. If the cold water supply fails, the water flow is stopped so that the user cannot scald himself. Integrated silencers minimise noise, making HEWI shower thermostats also extremely quiet in use. Due to their intrinsic safety and hygiene technology, HEWI shower thermostats are particularly suitable for demanding use in hospitals.

Taps and washbasins for kids

Easy operation for children

You will recognise HEWI mixers for children because they are particularly easy to operate. Various forms of operation train children's motor skills. With just one control element, the HEWI single-lever washbasin mixer can precisely and comfortably  adjust both water quantity and temperature at the same time. Because the operating lever is so easy to move, even small users find them easy to use.


HEWI System design

Consistent design

System 162

System 162 allows for a consistent, purist design concept right from the entrance door to the bathroom. A striking design element is the mitre cut, which emphasises the straight lines of System 162. Individual elements are characterised by a deliberately restrained design - purity in its purest form.

System 800 K

A simple, clear design, high-quality, glossy polyamide together with the targeted use of colour, define the design of System 800 K. White is the basic colour of the sanitary system. There is a choice of classic pure white or radiant signal white. The functional elements can be ordered in colour on request or are also available in white.

System 100

Reduced to the essentials is the design principle of System 100. Its minimalist design language was inspired by classical modernism. System 100 is hugely impressive, well considered right down to the smallest detail and with clever functions. Perfectly easy to use and made using materials of the highest quality.

System 800

System 800 combines organic shapes with purist design. Harmonious radii and clear lines characterise the accessories. System 800 is the perfect combination of clarity, emotionality and function.

Range 477/801

Series 477/801 combines the classic with the modern. Its timeless design has made the sanitary series a classic in the bathroom. High-gloss or matt, coloured surfaces, precise workmanship and intelligent functions are the hallmarks of Series 477/801.
