With a width of just 695mm, Vaillant’s ecoCRAFT commercial floor standing boiler range are delivered to site on a single pallet, offering optimal manoeuvrability for flexible siting. The ecoCRAFT range includes six models, beginning at 80kW, and enables the closest load matching with modulation ranges as wide as 17% to 100% on the 160kW boiler. ecoCRAFT boilers can also be installed in cascade utilising the VRC 630 or VRC 700 with eBUS control. Ideal if you need extra power behind your system on larger commercial projects.

ecoCRAFT also pairs a horizontal firing burner with a modular heat engine. Together, they drive running costs down, while delivering optimal power and efficiency. The design of the modular heat exchanger, utilises a single pre-mix burner and fan to achieve part load efficiencies as high as 108.4% (net) and a class rating of NOx class 5, to help maximise your Building Regulations rating.

Please note that ecoCRAFT boilers are not suitable for LPG applications.
