Fox & Co offers a 5-year guarantee on all ecoTEC plus and ecoTEC exclusive domestic boilers, or a 3-year guarantee on its ecoTEC pro models. .
With this increased guarantee and the fact that the ecoTEC range of high efficiency boilers have all been given the Which? best buy status and can also help you save up to a third off your annual home heating bill, it means you will have even further peace of mind when choosing Vaillant.
How the extended guarantee works.
Once your new ecoTEC Plus boiler has been installed, I will send your guarantee registration card to Vaillant. As long as this is completed in full (including your boiler serial sticker as proof of purchase), Vaillant will then process and send you confirmation of your increased guarantee.
