Viessmann Boiler Servicing

Viessmann highly recommends that you have an annual boiler service. Why is it so important? Well, as with all boilers, when they are not maintained properly, they start to produce harmful by-products which can be hazardous to your health. We acknowledge the seriousness that this situation may bring, so we never rush a boiler service. Instead, we take as long as needed to carry out a full service, making sure that your boiler meets ALL current regulations. In doing so, you will have the added bonus of an efficient boiler which will run smoothly and help to keep the heating costs down.
