DHW heating and central heating backup with solar energy Solar thermal systems are ideally suited for DHW heating and central heating backup. Thanks to the freely available solar energy, your investment will pay for itself within a few years through high savings on fossil fuel. Of course, new build is optimally suited for the perfect design of an energy-saving heating system. For this, Viessmann offers the ideal combination of advanced condensing technology and powerful solar collectors. You basically have the option of using solar energy for DHW heating and central heating backup. The savings on oil or gas are considerable, as you will be able to reduce your energy consumption, required to heat DHW for the daily demand, by 60%. If you combine the heating of DHW and heating water, your annual savings will be around 35% of the total energy required. Solar thermal system with dual-mode DHW cylinder The heart of this solution is the dual-mode DHW cylinder, which has two water circuits flowing through it. When there is sufficient solar energy, the heat transfer medium in the solar thermal system heats up the water in the DHW cylinder via a heat exchanger. When the temperature drops through water being drawn off, such as for a bath or shower, the boiler will start if required to provide additional heating via the second circuit. With Viessmann, the complete heating and solar technology comes from a single source. All components are perfectly matched. The range in which additional energy must be provided ultimately depends on the size of the collector area and the capacity of the DHW cylinder. Solar thermal system for DHW heating and central heating backup The heat transfer medium heated up in the solar collectors can be used for back-up heating of the heating water, as well as for DHW heating. For this, the heating circuit, via a heat exchanger, uses the water in the DHW cylinder that is continuously heated by the solar collectors. The control unit checks whether the required room temperature can be achieved. If the temperature is below the set value, the boiler will also start. It is not until this point that fossil fuel in the form of oil or gas is consumed. 10/11
