auroSTEP solar water heater is manufactured in a German plant which is one of the most modern plants in Europe, with exclusive Vaillant components, with maximum quality, robustness and reliability.

Our system is innovative and different compared to competitors products in its function and its manner of installation. It is a well-outlaid drainback system with high efficiency. In the interior of the installation we find a solar liquid (mixture of glycol and water) and air, therefore there is no need for determined hydraulic components as for example expansion vessel, exhaust fan, manometeretc. as there is practically no pressure in the system.

When the central control unit puts the integrated pump in function, it begins to transport the solar liquid from the serpentine of the accumulator through the tubes to the solar panels where it is heated and sent back to the accumulator to heat the stored sanitary water. During standby the solar liquid is stored in the tubes at the bottom of the system, the collector contains nothing but air. Therefore there is no loss of efficiency due to stagnation of the system, different from pressurized solar systems.

Our newly launched auroFLOW plus Solar Thermal Drainback System combines all of the advantages of the very latest Vaillant solar technologies in an easy to specify and install pre-assembled kit. auroFLOW plus is the result of intensive research and development. Its the most advanced Solar Thermal Drainback system on the market and is designed to offer maximum efficiency, high performance and total reliability.

This easy-to-install system comprises a collector array, high efficiency pump, drainback vessel, heat exchanger and control. Also, auroFLOW plus takes up less space, all components are contained within the module, and the use of standard 15mm and 22mm copper pipe with compression or hard soldered / brazed fittings. auroFLOWs on-demand reheat cycle is unlike traditional solar systems that can go into stagnation, as the solar fluid drains back into the vessel once hot water demands are met.

We have designed and developed auroFLOW plus for properties with higher daily water usage a versatile, quick and easy to install Solar Thermal Drainback system that comes with our market leading stamp of innovation, quality, reliability and support.

auroFLOW differs from pressurised systems by enabling solar fluid to drain from the collectors back into the system when the hot water demand is met . The system design prevents solar liquid from stagnating making it ideal for all applications where hot water is not required during shutdown periods. By their very design, drainback systems are far simpler than pressurised systems. They are lower maintenance, more easily specified and require less time to install.

auroFLOW plus can be used alongside conventional Vaillant hot water heating systems - VPM 15 D for up to 6 collectors, the VPM 30 D for up to 12 collectors or even larger commercial systems requiring more than 12 collectors, up to 4 collector arrays can be used totalling 48 collectors. The VRC 630 conventionally controls Vaillant cascade boilers, however where auroFLOW Plus is added to the system the VRS 620 can be used.

VRS 620 features

• Consolidated kWh solar gain is displayed on the front page and monthly reports are available
• Single Cylinder sensor (SP1) used rather than multiple sensors.
• Time is synchronised between modules
• Date is synchronised between modules

The collector isMCSapproved so it qualifies for appropriategovernment grants and incentive schemes

Vaillant atmoMAG gas water heaters are especially designed for hot water generation. The latest atmoMAG line is the result of decades of continuous development and state-of-the-art technology, providing you with the highest level of warm water comfort and energy efficiency.

Convincing warm water comfort thanks to intelligent solutions OPTI MOD Function

Vaillant Gas Water Heaters atmoMAG owe their high warm water comfort to their integrated OPTI-MOD function. It ensures highest comfort with utmost efficiency. With two simple steps the users can adapt the atmoMAG to their individual requirements. OPTI. refers to the preselection of the appliances' water output between approx. 50% and 100%. As a rule the inlet water flow through the tap determines the outlet temperature. This method offers advantages with high inlet water temperatures. Since the incoming water is preheated, less gas is needed to reach the outlet temperature. This saves a lot of energy. .MOD: keeps the water temperature constant independently of how far the tap is opened. The burner flame adjusts itself automatically, thus the minimum gas rate required is used to heat the water up to the desired temperature chosen by the user.

The best starting sytsem for every requirement

All atmoMAG with OPTI-MOD function show the same high warm water comfort. However, their ignition systems may differ. The piezo ignition of the MAG XZ represents a perfect standard solution which has proven itself for decades. With increasing requirements on energy savings, the MAG XI is the one to count on. Its electronic ignition works with main connector or batteries. Giving up the permanent pilot flame leads to a remarkable saving of energy without interference in the various stages of operation. The batteries, if used, can easily be replaced at the front of the appliance. Their durability is a minimum of one year. Our model especially designed to meet basic requirements - please see our technical data.

Ground source heat pumps offer excellent energy savings as up to 75% energy for heating can be extracted from the ground. Energy from the ground is converted into useful energy by the heat pump, which works like a fridge. It uses electricity to run the compressor and controls and it is an excellent partner for underfloor heating, which requires low water temperature to heat the home. Suitable access is required to allow boreholes to be drilled or ground collectors to be installed.

Buffer and multifunctional-storage for all requirements and heating systems - with particularly efficient solar use.

Multifunctional storage allSTOR can be implemented with all kinds of heat generators: with Solarsystem, Heat pump, Gas, Oil, Pellet boilers, Fireplaces and CHP. You can select from six different sizes of 300-2000 liters to suite your needs. A cascade connection of storages can provides up to 6, 000 liters of hot water.

The allSTOR is the best choice for DHW and heating support and it uses the solar system more efficient than any other storage on the market. The plug-and-play station for solar chargeing and drinking water with its own control unit can be mounted directly on the storage or on the wall next to it. The allSTOR plus serves as temporary storage for heating water and thus increases the efficiency of any heating system.
