Super service, they assisted me in the middle of their holidays. Whatsapp support with photos is also available. Very friendly people. Stephan has been visiting us. He replied my 20+ questions regarding Radiators, Heaters, Energy Saving. They work very professionally. I always get a report of what has been checked for each visit. They started rejected new customers just to give better service for the existing customers. I completely recommend this company for Dutch and also English speakers.

We receive a phone call every year at the beginning of July to schedule a maintenance appointment. Our boiler is now 19 years old and still in perfect condition, thanks in part to the maintenance and helpful tips from Thijssen! They're also always up for a friendly chat during the annual maintenance.

There was something wrong with our boiler, and it was repaired quickly. Excellent service. I'll contact them for maintenance as soon as possible.
