Vaillant transforms its range

Vaillant has replaced its ecoMAX commercial boilers with a new ecoTEC range of high efficiency commercial system boilers.  The new models – the ecoTEC 46 and ecoTEC 65 – are high efficiency, SEDBUK ‘A’ rated boilers, which produce a heating output of up to 65 kW.  Both models feature a fully modulating class 5 low NOx burner and fan.
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.
