Boilers | Energy Control Steam and Hot Water Boiler

A steam accumulator is a pressure vessel (or tank) with internals and controls, that can reduce the fuel consumption, maintenance costs and increase the service life of your boiler by stabilizing the steam draw conditions, but it cannot make up for shortcomings in total boiler capacity. The accumulator acts as a flywheel or capacitor, storing energy for short periods until the process requires it.
