While solar energy is very environmentally responsible, it isn't available around the clock. With the SPU-2-W buffer cylinder you can store free solar energy and use it for your heating later. Of course the SPU-2-W can also be combined with any other energy source, such as oil or gas. This 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). This means you always have enough heating water for your detached house or apartment block, while also taking care of the environment as well as your wallet.
You can now make use of free solar energy for even longer – with the SPU-2-W buffer cylinder. The SPU-2-W can store the heating water supplied by a heat generator, such as a gas or oil boiler, while also absorbing the heat generated by your solar thermal system. At a later point the cylinder releases this energy into the heating system. For you this means, above all, that you can always benefit from the cosy warmth you need for your home, while also knowing that you are doing something positive for the environment.
