Warmteservice: Yenlo helps to automate the human way

In 1964, engineer Theo de Bruin sr. starts his own business in the Haarlemmerstraat in Amsterdam, the Netherlands. In his shop, he sells fittings and boilers to other engineers and installers. When his son Theo jr. joins in in 1989, things start moving. Not only does Warmteservice open new offices in both Amsterdam and other parts of the country; the offer gets expanded drastically.


There was a time that Warmteservice was just this little shop in Amsterdam. Whoever was looking for a solid central heating system and tailor-made advice, made his way to the de Bruin family. Those days are over. Today, Warmteservice consists of 53 branches and an online shop. Still their recipe for success remains the same: quality products; experts behind the counter. How does such a big company stay in touch with its customers? The answer is simple, as it’s all about good communication, both internally, on the work floor and in cooperation with integration partner Yenlo.

Warmteservice has moved with the times. What once started as a small family business dealing in central heating systems, has now become a key player on the Dutch installation market. In addition to heating systems, products and services for electricity, plumbing and roofing have been added to the product range.

The Warmteservice team combines knowledge of the market with engineering and IT expertise, which makes them fast, flexible and innovative. But despite the many changes that Warmteservice has made, the team never seemed to have lost sight of their main principles.

“Our relationships with customers and suppliers are still very personal”, as Ifran Laloe, ERP Developer, explains. “And with that attitude, there’s room for innovation and new investments.”

The challenge

Until recently, Warmteservice worked with multiple, separate systems. Data streams for customers, orders, products and invoices were all managed separately and many of these messages were dealt with locally.

This system worked perfectly fine, until the company got so big that the relatively small IT department could no longer oversee all data processes. The Warmteservice team started looking for a solution and decided to purchase an ESB, which is a smart product that receives messages and not only forwards, but also translates and configures them.

This way, the IT department could easily set up workflows for different data streams without having to deal with all messages separately. This seemed like a simple and efficient solution. However, finding the right ESB vendor was a different story.

Unfortunately, the relationship with their new ESB partner was a short-lived one, as the ESB vendor would soon sell all its products and licenses so that the supporting partner was no longer of any use to Warmteservice. The search for an ESB and new ESB partner started again, which was actually quite fortunate, as Dutch firm Yenlo had just partnered up with WSO2, offering the latter a new chance of collaboration with Warmteservice.
