Vaillant Group International products

People who want to heat in an environmentally friendly way can now do so with the aroTHERM plus. The new air-to–water heat pump combines great performance, energy efficiency and sustainability.

With the flexoTHERM range, Vaillant provides the latest technological evolution of heat pumps. EVI (Enhanced Vapor Injection) technology achieves particularly high seasonal yield levels, far above those achieved with any other compressor technology, applied to water-to-water or geothermal heat pumps. This model of refrigeration circuit management allows working at high production temperatures, obtaining higher power levels and high efficiency.

If you want to combine a heat pump without an integrated cylinder with a solar system for hot water preparation, then the best solution is the new solar hot water cylinder for heat pumps,geoSTOR VIH RW 400B and VIH RW 300, because it stores the heat from the heat pump and the solar system in equal measure. If there is sufficient solar output in summer, the heat pump can even remain switched off; the solar system takes over hot water preparation by itself.

An allSTOR system usually consists of the storage tank itself, a Vaillant solar pumping station for the more efficient use of solar energy and / or a Vaillant domestic hot water unit for the highest possible hot water comfort. Both system parts are complete ready-to-plug modules which can be installed side by side or above each other on the front of the storage: quickly, easily and aesthetically pleasing. An on-wall installation is also possible, if desired.

AuroFLOW plus is the latest solar drainback station for new installations and also for existing solar heating solutions up to 120 m2 of collector area. It can simply and easily be combined with several allSTOR exclusive accumulators and auroTHERM VFK 135 VD solar thermal collectors. With a drainback system the fluid is protected against stagnation and freezing as it is automatically drained, by gravity, to the solar station and as soon as the need for heat ends. The regulation of the solar system is done quickly and easily, and all information on its operation can be viewed on its digital back-lit display.

The solar system auroSTEP plus offers the opportunity to use new solar thermal technology for warm water generation in your home, without having to deal with the problems that are usually associated with solar systems. Vaillant presents a system that is easy to implement and offers calculable costs. The solar system package auroSTEP plus contains a solar storage with a pre-mounted solar pump, an integrated solar control, a corresponding auroTHERM flat plate collector (or collectors – depending on the system) and the compatible installation accessories for the particular type of roof. This is a well adjusted system for standard installation which does not require detailed planning. The auroSTEP plus storage is available with 150, 250 and 350 litres volume.
