New for 2009 - ESBE VTC311 Solid Fuel Valve

Our prices include VAT and delivery

The ESBE series VTC300 is a thermal 3-way valve designed to protect the boiler from return temperatures that are too low. Often referred to as riser valves they are ideal for wood pellet boilers and wood pellet stove-boiler systems and are now recommended with all our products. For log burning stoves and boilers please select the VTC500 as an alternative. The VTC300 valve maintains a high and stable return temperature means a higher level of boiler efficiency, reduced tarring and increased life span of the boiler. Utilising the VTC300 together with the smaller pellet stoves with back boilers significantly increases the startup efficiency of the stoves. Instead of pump stopping and starting to maintain the water temperature, the pumps remain constant gradually increasing the temperature into the heating system. ESBE are the valves of choice on all Extraflame boiler systems.

The VTC300 valve is used in heating applications up to 30 kW where solid fuel boilers are used to feed storage tanks. The valve is installed either in the return pipe to the boiler (45°C, 55°C, 60°C, 70°C or 80°C) or in the accumulation tank feeding pipe (70°C or 80°C). The first option is recommended as it offers a simpler pipe layout for expansion. EcoEnergy recommend and stock the VTC311 with a 55°C return and 3/4" inch internal thread, but can supply other valves on request.
