1 ROTEX Solaris Sunny prospects The high performance ROTEX Solaris solar system exploits the energy from the sun for hot water and heating. Hygienic, with maximum efficiency and cost saving.

2 "Of course, we wanted to do something for the environment and save money at the same time. And we wanted to be able to take our modernisation step by step. With many of the systems available on the market we quickly lost the overview. Our heating expert convinced us to use the ROTEX Solaris system. And he kept his word. Hot water for showering and bathing is provided by the sun every day beneficial to the environment and free of charge. And the solar system even supports our heating system in the winter." Stefan and Sabine Heller 2

3 ROTEX ROTEX variocistern Solaris Welcome to the sunny side. An investment in a sunny future. If you are planning investment in a new heating system today, you should take the supplementation by a solar system into account from the very start. The heating system should at least offer the option of being able to supplement it by the addition of a solar system in the future without any problems. The advantages are obvious. Low energy consumption not only means low costs. It is also a con temporary and responsible action with regard to our environment. ROTEX offers modern heating systems where all the components are perfectly matched to each other. And, of course, the utilisation of free and environmentally beneficial solar energy for hot water generation and heating support is planned in as an option in all ROTEX systems. Efficient, flexible and environmentally beneficial. Modern solar systems can, at their peak, transform up to 80% of the free solar energy into usable heat and supplement any heating system in an ideal manner. It was against the background of these requirements that the ROTEX Solaris was developed and a completely innovative solar system was created. In combination with the quick direct storage of the heat in the solar thermal store, the enormously high thermal efficiency of the ROTEX Solaris flat solar panels guarantees a high energy yield even with relatively brief solar radiation. ROTEX Solaris uses solar energy for water heating and effectively supports heating. If the energy is not used immediately, the ROTEX solar thermal store can store large amounts of heat and the heat can be used even more than a day later for hot water or heating support. Your advantages with the ROTEX Solaris: Efficient utilisation of free solar energy for hot water and heating Hygienic hot water generation Optimum temperature stratification in the ROTEX solar thermal store increases solar use Perfect incorporation with the most varied of heating systems kwh Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Unbeatable supplementation: Thermal solar energy exploitation. The diagram shows the monthly energy consumption of an average singlefamily house. Here we have an example combined with a ROTEX heat pump that also uses regenerative environmental energy. The use of the required auxiliary energy falls to an absolute minimum. Solar energy utilisation for hot water and heating Heat pump (environmental heat) Auxiliary energy 3

4 4 ROTEX Solaris solar panels. Efficiency to the third power. The Solaris solar panels convert almost all of the shortwave solar radiation into heat through their highly selective coating. The three different solar panel sizes mean there is flexibility in adapting to roof characteristics. Since all buildings are different, there are various installation options for fitting the ROTEX flat solar panels onto the roof. The solar panels can be fitted onto the tiles (on-roof), into the roof (in-roof) or also with a special substructure onto a flat roof.

5 ROTEX ROTEX variocistern Solaris Solar systems. By ROTEX. ROTEX Solaris: 2 possibilities. Always the first choice. ROTEX Solaris is available in two different variants, that meet all structural conditions and individual requirements. 1. The pressurised solar system (Solaris-P) The pressurised solar system impresses with its simple installation and is suitable for all applications and buildings. It operates efficiently and safely at any desired length of pipes and feed height. The well-engineered structure of the ROTEX solar thermal store means that an additional plate heat exchanger is not required. A bivalency heat exchanger for pressurised solar or other heat sources is already incorporated. That makes the system simple and flexible. 2. The direct Drain-Back system (Solaris-DB) If the constructional conditions permit, we recommend the unpressurised and direct Drain-Back system. The water in the store is supplied directly and without heat exchanger to the solar panels, heated and then stratified into the store. This considerably increases the efficiency of the solar collectors and the entire utilisation of the installation. Since the system is unpressurised, components which would otherwise be required are not necessary, such as the expansion tank, pressure relief valve, pressure gauge and heat exchanger. The Solaris solar panels are only filled if there is enough heat from the sun and if the thermal store can absorb heat. The fully-automatic control system controls the system independently to provide optimum utilisation of the solar energy. If the sunshine is insufficient, or if the solar thermal store does not need any more heat, the feed pump switches off and the entire solar system drains into the thermal store. The addition of antifreeze agents is not required since the panel surface is not filled with water when the system is not operating. This is a further plus from the environmental perspective. The principle functions only if the connection pipes in the building and on the roof are installed with a constant gradient. If this is not possible, the pressurised solar system is the optimum alternative. Solar energy in store. The ROTEX solar thermal store. ROTEX Solaris uses solar energy for water heating and effectively supports heating. In all ROTEX solar thermal stores, and the gas condensing/solar combination (GCU compact) and heat pump/solar combination (HPSU compact) with a storage tank volume of 500 litres, solar heating support has also been integrated ready for connection, alongside the solar hot water generation. If the solar heat is not consumed immediately, the ROTEX solar thermal store can store large volumes of solar heat and it is possible to use the heat for hot water or heating hours later or even the next day.

6 "Since we have been using the ROTEX solar system, I always have a good feeling when I turn on the water tap. On the one hand, because I know that the hot water generation is carried out using environmentally beneficial and free solar energy. On the other hand, because I can be sure that the water is also hygienic and clean at all times". Stefan Heller, about his experiences using the Sanicube solar thermal store 6

7 ROTEX ROTEX variocistern Solaris Clean energy, clean drinking water. The perfect thermal store the right temperature in each layer. The thermal store on the ROTEX solar thermal store is a double wall fully plastic structure. The space between the internal and external tank is filled with expanded foam and is extremely heat insulating. On the inside, depending on the design, there are two to four heat exchangers made of stainless steel corrugated pipe. The 300 or 500 litre tank is filled up once with unpressurised tap water without additives. Solar collectors work more efficiently the colder the water is that flows through them. In thermal solar systems it is therefore important that the thermal store has the best possible pronounced temperature stratification behaviour. With the ROTEX solar thermal store, the cold fresh water is fed into the corrugated pipe heat exchanger made of highquality stainless steel, at the lowest point of the thermal store. From here it is directed upwards and heated using the continuous heating principle. This ensures that the temperature in the lowest part of the thermal store from where the solar panels are supplied with water is cooled to the maximum. The temperature stratification generated in the ROTEX solar thermal store increases the overall exploitation of the solar installation. Healthy unadulterated enjoyment. Water hygiene has specific emphasis at ROTEX. This is an extremely important subject, particularly in solar energy exploitation, because, when using conventional, large volume solar storage tanks, deposits of sediment can arise. The "thermal store principle" used by ROTEX meets the latest thermal technology and water hygiene requirements, as confirmed by extensive investigations carried out by the Hygiene Institute at the University of Tübingen. As a result of its design concept it ensures large storage tank capacities with outstanding water hygiene and thus differentiates itself fundamentally from previous large volume hot water thermal stores. Because you should never compromise where health is concerned. The anti-legionella solar thermal store. The structure of the ROTEX thermal store ensures optimum water hygiene since the water to be heated is carried in a pipe system. Deposits of sludge, rust, sediments or even the multiplication of dangerous legionella bacteria, which can arise in many large-volume tanks, are not possible. The exceptional water hygiene benefits of this thermal store concept have been confirmed by the Hygiene Institute at the University of Tübingen in an extensive study. 7

8 The ROTEX compact class: Compact combination of heat generator and solar thermal store. Dream dimensions for your heating: Heating and hot water in just 0.36 m 2. Irrespective of whether with or without solar energy exploitation, the ROTEX GCU compact and HPSU compact are an optimum combination of high efficiency condensing boiler and hygienic thermal store. As a result of the uncompromising combination of these functions, these compact units set new standards with regard to space saving and energy exploitation. An area of only 0.36 m 2 (300 litre storage volume) or 0.64 m 2 (500 litre storage volume) is sufficient to accommodate the complete heating, hot water generation and stratified solar thermal store. Gas condensing technology and solar energy. The ROTEX GCU compact combines modern gas condensing technology with solar thermal store in the smallest possible space. The integration of the condensing heating boiler on top of the thermal store means that the surface losses of the unit are kept to a minimum. Losses as a result of cooling, as occur in usual boiler storage combinations, do not occur here. This ensures that you save even more energy. The heat pump + solar energy. ROTEX offers an especially compact and pioneering comprehensive solution in the form of the new heat pump unit, the HPSU compact. The HPSU compact exploits free and regenerative environmental energy from the sun and the air. The internal unit of the heat pump and the stratified solar thermal store are also combined here. The HPSU compact can not only provide heating but can also cool if required. The Hybrid central unit open for all energy types. All ROTEX solar thermal stores can also be used as an efficient thermal store for additional heat sources. For example, in addition to a solar system, a fireplace with water pocket can be used to provide support during heating and hot water generation. If you are not installing a solar system directly, it can retrofitted quickly and easily at any time Air-to-water heat pump, ROTEX HPSU compact 2 Gas condensing/solar combination, ROTEX GCU compact 8

The complete heating centre is accommodated on just 0.36 m². Oil condensing + solar. In combination with the ROTEX Sanicube thermal store, the ROTEX A1 oil condensing boiler is the ideal combination. Even in modernisation. Heat pump + solar. In combination with the air-to-water heat pump ROTEX HPSU compact and underfloor heating, you can enjoy the dual function of heating and cooling. 9
