Best Selling Vaillant Boiler
The Vaillant ecoTEC Plus stands out as one of the best-selling Vaillant boilers, praised for its versatility, efficiency, and advanced features.
This model is available in a wide range of sizes, from 26kW to 40kW for combi versions and 12kW to 35kW for regular boilers, making it suitable for small to large households.
Its ErP A-rating for energy efficiency ensures reduced energy bills, while the Quiet Mark certification highlights its silent operation, ideal for homes where noise is a concern.
The ecoTEC Plus is favored by homeowners and heating engineers alike due to its user-friendly interface, robust build quality, and compatibility with Vaillant’s vSMART thermostat for intelligent heating control. Its 10-year extended warranty further enhances its appeal by offering peace of mind.
Maintenance and Servicing
Vaillant boilers are designed for reliability, but like any heating system, they require regular maintenance to perform at their best. Annual servicing is essential and typically costs between £70 and £120, depending on the provider.
This routine check ensures the boiler operates efficiently, extends its lifespan, and keeps energy bills manageable. A certified Gas Safe engineer inspects and cleans key components, addressing potential issues before they become costly repairs.
While this adds a minor ongoing expense, it’s a worthwhile investment to avoid unexpected breakdowns and maintain the warranty, which often requires proof of yearly servicing.

Vaillant offers robust warranty options to ensure peace of mind for its customers. Standard warranties typically range from 2 years (e.g., ecoFIT Pure) to 5 years (e.g., ecoTEC Plus and ecoTEC Exclusive).
