A buffer cylinder operates like a battery: It can absorb heat in the form of warm or hot water and release it again later. A cylinder gives you the advantage of being able to balance out time differentials between heat being generated and consumed. This extends the service life of system components and increases the efficiency of your central heating system, as it isn't continuously cycling on and off on demand (fewer burner starts). The SPU-2 can easily be combined with one or more WOLF heating appliances, such as a gas or oil boiler, and is equipped with high grade thermal insulation.
The efficient buffer cylinders from WOLF store the heating water from your heat generator, such as a gas or oil boiler, and later release it into the heating circuit or freshwater module.
You can take it easy: Buffer cylinders from WOLF provide you with heat whenever you need it, protect the components of your heating appliance, save energy and also help protect the environment.
