Fast, instant help via video chat.

Even during the current coronavirus crisis work on heating, water supply and sewage disposal systems is indispensable for you as a professional installer, specialist consultant and operator. How about always having a technical advisor at your side during pump service, despite these difficult times, while also ensuring that personal contact is hardly required at all? Not possible? Make it happen with the Wilo-Live Assistant, the mobile and digital solution for all questions about pumps and pump system solutions! To ensure interactive support, we have introduced facilities for live video chatting with our customers on site. This way, we can help you solve your problems as quickly as possible. We prevent downtime and ensure operational reliability of your pumps and systems! If you have questions, errors or breakdowns you can rely on fast support from a Wilo pump expert at the push of a button.

What is the Wilo-Live Assistant and how does it work?

By using the Wilo-Live Assistant, our expert advisers can support you in the boiler or equipment room via video transmission – live and in real time. You use your smartphone to show the installation set-up, while the Wilo expert follows everything on their screen. They can see the components as well as other details and can thus determine where the fault or breakdown originates. In addition, the Wilo expert can draw helpful hints directly on the image and send any documents you require such as excerpts from the user manual, which you can also see on your smartphone display.

What do I need to use it?

To use the Wilo-Live Assistant, you need a current iOS or Android smartphone with an Internet browser (Safari, Google Chrome, Opera, Microsoft Edge) and an Internet connection. An app is not necessary.

How do I gain access?

Access will be provided by our local service organisations, who will get in touch with you via phone initially. If it turns out during the conversation that video support can answer your questions in a faster and more targeted way, our employees will send you a link to your smartphone via SMS or e-mail. After clicking on the link, you just need to enable access to your smartphone microphone and camera and you're good to go. Of course, your data is protected at all times. No storage takes place, and the videos are not recorded. Only you have access to your smartphone.

We install customer satisfaction.

Our experienced Wilo service offers installation of our pumps or pumping systems by our own service teams. We offer an end-to-end process from gathering information on site to installing our product in the overall plant. The professional inspection of the installation set-up and the assembly of all necessary components lay the foundation for the successful commissioning of the system.

Damage and the associated consequential costs can only be avoided through an optimal installation set-up and the interaction of various individual factors. In addition, Wilo offers test runs and briefings for your staff. This is not only for Wilo products, but also for third-party components.

Commissioning

High performance is our strength.

Entrust the Wilo commissioning-service with ensuring a smooth process when implementing new systems in your installations. We will happily accompany you throughout the commissioning process of our products and support you step-by-step. You will benefit directly from the advantages of our products and their performance in operation. Our qualified service technicians will familiarise you with all strengths to guarantee a safe and optimal start.

Why you should take advantage of our commissioning expertise:

The pump is part of a complex supply system, that is why the focus of professional installers during commissioning is primarily on the higher-level system technology. However, the optimal pump settings – as a part of the overall system – are crucial for energy consumption and therefore for the efficiency and operational reliability of the entire system.

The advantage of using professional installers is that they hand over a system to the customer which is energy efficient from the start and they do not have to acquire detailed knowledge of each control and pump series for this. This significantly reduces both energy costs and pump wear. The commissioning service provided by the Wilo service also includes instruction of the responsible building service engineer.

Services focused on efficiency.

Optimising your pumps and pump systems is one of the best ways to ensure the best operational reliability of the overall system. Existing systems can often be optimised through minor changes and adjustments, allowing efficiency, and therefore effectiveness, to be significantly increased.

Wilo offers tailor-made solutions to suit customer requirements in order to provide sustainable, competent and cost-effective individual support.

Proactive system optimisation has advantages for all sides. You save energy and costs, improve the sustainability balance of your buildings and installations, and bring your technology up to date at the same time. This significantly reduces the risk of equipment failure and further reduces maintenance costs.

Energy Solutions

How can we help you to unlock hidden savings?

Pumps are responsible for around 10% of global energy consumption. This is a considerable amount, but at the same time it poses a great opportunity. After all, this is precisely where it is worth starting in order to reduce the operating costs for public, commercial and industrial buildings and systems.

More than two-thirds of operators are currently still using pumps which consume more energy than is necessary in the building services sector alone. Proactive change has advantages for all sides. You save energy and costs, improve the sustainability balance of your buildings and installations, and bring your technology up to date at the same time.

This significantly reduces the risk of equipment failure and further reduces maintenance costs. With Wilo-Energy Solutions, we point out possible energy savings and take responsibility for future generations and the fight against climate change.

Wilo-Energy Solutions involves Wilo high-efficiency technology to proactively replace pumps and pump systems which are still functioning but are inefficient. This allows you to reduce the energy consumption of pumps in your buildings and systems by up to 90% and profit from added benefits such as future security, supply security and hygiene safety.

Optimising or replacing existing systems with new, highly efficient solutions (products, services, know-how) also has a positive impact on operating costs, operational reliability and CO2 emissions.

We offer you targeted consultancy and analysis, including the involvement of subsidies as well as comprehensive support around the changeover to high-efficiency technologies.
