• Online configurator enables do-it-yourselfers to plan their underfloor heating systems themselves
• Item parts lists are updated in real time with availability and can be placed directly in the shopping basket

Marburg, 30 August 2022 - Selfio GmbH, a wholly owned subsidiary of 3U HOLDING AG (ISIN: DE0005167902), has expanded its product and consulting portfolio to include an online configurator for underfloor heating systems. For the first time, customers can now also plan their underfloor heating projects themselves and online via the site https://fussbodenheizung-konfigurator.selfio.de/.

With this innovative service, Selfio is further expanding its position as one of the leading online suppliers of high-quality underfloor heating systems.

The online system was realised internally by a development team of 3U subsidiary weclapp SE on the basis of Selfio's many years of experience with underfloor heating systems. It is an innovative, fully-fledged tool for online project design and calculation: With the input of the required planning parameters, it automatically calculates the layout of the entire underfloor heating system, the required components and materials and provides a complete and reliable product list. The customer's individual wishes and preferences are taken into account. The resulting shopping basket is based on current article information and stock levels or availability at the online shop selfio.de, and delivery and price conditions are displayed. The information for customers is thus always up to date and can be directly converted into orders.

Under the motto "Do it yourself. But do it right!", Selfio offers a comprehensive service to do-it-yourselfers and sees itself as a partner in the implementation of construction, renovation, and modernisation projects. In addition to the material in the online shop with heating, air conditioning and sanitary technology products, Selfio also offers expert advice in the form of explanatory videos and tutorials. The configurator supplements and expands this range of advice with an essential, innovative element.

"Helping our customers to make their project a success: That is our mission. We offer them innovative solutions that make building and renovating easier, cheaper, more climate friendly. This has always included intensive advice - online and in person - so that our customers can tackle even large projects on their own. With the underfloor heating configurator, we simplify their planning considerably. With such customer-friendly service and high quality, we are laying the foundations for further growth and increasing profits," emphasises Selfio Managing Director Roger Moore.

Background: On average, 70 percent of household energy costs in Germany are caused by heating. Underfloor heating systems play an important role in implementing the energy transition and reducing costs in the private building sector. The energy-efficient surface heat makes it the ideal partner for modern heating systems to reduce CO2 emissions. With strategic product development and expansion of the portfolio of own brands, Selfio offers a comprehensive range of underfloor heating systems that meet the requirements of different installation situations and are just as suitable for retrofitting in existing buildings as for new ones.
