VELORA-Eco Pro-Energy freestanding unit with a 477-liter water storage tank and a 10 kW Altherma 4 H outdoor unit.

The VELORA-Eco Pro-Energy 4 H heat pump stands out in the world of air-to-water heat pumps. The latest addition to the successful VELORA-Eco Pro-Energy range, this hydrosplit model, using the natural refrigerant R-290 (propane), represents an innovation combining maximum efficiency, safety, and durability. VELORA has successfully met the challenges associated with using this flammable refrigerant and has developed a revolutionary concept that redefines R-290 standards.

The VELORA-Eco Pro-Energy 4 H ECH₂O indoor unit is an innovative air-to-water heat pump for indoor use, combining heating, cooling, and domestic hot water production in a single system. Thanks to state-of-the-art technology and exceptional energy efficiency, it guarantees sustainable, comfortable, and economical operation in your home.
Its fresh water operating principle ensures hygienically pure hot water at all times. Unlike conventional hot water tanks, no legionella disinfection by heating is necessary, which further improves the system's efficiency and guarantees safe operation without complex maintenance.
The integrated hot water tank is completely maintenance-free, as it is protected against corrosion and limescale deposits. The absence of a sacrificial anode also eliminates significant maintenance requirements. Furthermore, the absence of a safety valve ensures optimal durability and water savings.
The VELORA-Eco Pro-Energy 4 H ECH₂O is designed to deliver efficient heating performance even under extreme conditions. The heat pump operates reliably down to outdoor temperatures of -28 °C. At the same time, the system guarantees a constant supply of hot water, even at high outdoor temperatures, up to 40 °C.
For optimal safety and performance, the heat pump is equipped as standard with a 9 kW auxiliary heater, providing supplemental heat even in very cold weather. In addition to its remarkable performance, the heat pump features an ultra-quiet night mode. This mode ensures virtually silent and therefore undisturbed operation, day and night. Control is via the new MMI-4 heat pump controller, which features an intuitive 5-inch touchscreen, offering user-friendly operation and displaying all essential information at a glance. The environmentally friendly refrigerant R-290 is used in an innovative way in the VELORA-Eco Pro-Energy 4 H ECH₂O to guarantee maximum safety under all circumstances. VELORA thus makes a significant contribution to environmental protection without compromising efficiency or operational reliability.

The VELORA-Eco Pro-Energy 4 H outdoor unit impresses with its exceptional energy efficiency, guaranteeing maximum heating performance and minimum energy consumption in all seasons. Its unique safety concept, specially designed for handling the R-290 refrigerant, is particularly noteworthy. It incorporates innovative safety features such as sealed printed circuit board enclosures, plug-and-play electronic components, an efficient gas separator, an integrated refrigerant transport tank, and reliable leak detection in both the indoor and outdoor units. These technologies make the VELORA-Eco Pro-Energy 4 H the safest heat pump in its class.
Another advantage is its versatility. Suitable for both renovations and new constructions, it boasts a modern design and ultra-quiet operation. Thanks to an enhanced sound insulation concept, including optimized insulation technologies, resonance chambers, and newly designed fans and louvers, the outdoor unit achieves an extremely low noise level of only 50 to 54 dBA. In noise-sensitive residential areas, it registers a sound level of only 28 dBA at three meters, while the modern design of the outdoor unit, with its elegant curved black fan shroud, minimizes wind noise and air resistance. The heat pump is perfectly suited
to extremely low temperatures: it guarantees operation down to -40 °C and, thanks to its multi-stage auxiliary heating, offers maximum efficiency with photovoltaic systems. Furthermore, the VELORA-Eco Pro-Energy 4 H is characterized by a relatively low refrigerant charge, thus setting a new benchmark in terms of sustainability...
