There are eighteen boilers in the current Vaillant Ecotec Plus range, including combis, system and open-vent boilers. There are also several models out of production but spares are still available. Models beginning with an 8 are combis, while heat only boiler models usually begin with a 4 and system boilers with a 6. The following two digits denote the boiler power (in kW). Therefore, the Vaillant 415 is a small Ecotec Plus heat-only boiler with 15kW of power, and the Vaillant 637 a top of the range system boiler rated at 37kW. Some of the combis have had several upgrades (at least five) since 2006. The current generation of boilers, and corresponding replacement parts, are exceptionally reliable. We supply only top quality parts from Vaillant’s current range. Our Vaillant Ecotec Plus 831 parts include the Vaillant Ecotec plus 831 diverter valve. Note that the Vaillant Ecotec plus 831 diverter valve is suitable for a wide range of models including the several revisions of the 831 (up to R5). In other words, the spare Vaillant Ecotec plus 831 diverter valve we supply is the improved part but is also suitable for retrofitting into older versions of this boiler. As with many Vaillant Ecotec Plus 831 parts, it can also be installed into certain other boiler models (including the 824, 837 and 937). If in any doubt about the compatibility of a part with your boiler model, please call us for advice. Our Ecotec Plus range also includes a Vaillant Ecotec Plus PCB replacement, a Vaillant Ecotec Plus 438 PCB, the Vaillant Ecotec Plus fan, and compatible sensors, pumps, heat exchangers, valves and service cocks for almost all models. If there is anything you can’t find, please just ask us to look for you.
