A number of major components are built into the boilers: the ecoTEC 65 has a siphonic condensate discharge, while the ecoTEC 46 has a condensate trap. Both models have built-in, two-stage frost protection, 8m head shunt pump and a sensor to monitor system pressure via diagnostics. There is a flow sensor to monitor the water flow through the boiler, as well as an air separator with auto air vent and filter for bleeding the system and the filtering of fine particles. Each boiler is equipped with a stainless steel heat exchanger and new hydraulic connections and isolating valves have been developed.

There are a number of flue lengths available for the ecoTEC commercial range, with a maximum flue length of up to 18m horizontally or 21m vertically, each with a 125mm flue and an optional 125mm stainless façade kit is also available.

Accessories
Optional components for the ecoTEC commercial range include low loss headers in four sizes and a push-fit flue system with telescopic accessories. There is also an array of intelligent eBUS contols, including weather compensators and a multiple boiler management control system VRC630. An LPG conversion kit is available for the ecoTEC 46 only.

Maintenance
For easy service and repair, there is a comprehensive, built-in boiler status and diagnostic display system. Parameters such as flow rate and system pressure can be monitored to aid fault diagnosis. The backlit display is blue for easy reading, while there is easy access to all components from the front. Maintenance is also easy with a single electronic circuit board and a flue gas analysis point.

The new ecoTEC boilers come complete with a one-year warranty as standard. A two-year warranty is also available if Vaillant commissions the appliance.
