Sustainability made easy: heat pump solutions for new buildings

Using environmental heat efficiently with intelligent heat pump solutions

Environmental heat: advantages all around

When building new homes, the goal is always to find a heating and hot water solution that fulfils today’s strict requirements of the German Energy Saving Ordinance (EnEV) as easily as possible. In single-family houses, this can be done fastest and most simply by means of a heat pump system. Building contractors and clients alike are increasingly looking for an energy-saving and environmentally friendly heating system that also offers a high degree of living comfort.

By using freely available environmental heat, heat pump solutions are especially environmentally friendly. When powered by energy from regenerative sources, they are even CO2-neutral. Their high efficiency at low flow temperatures allows a significant reduction in primary energy consumption and emissions. Even greater savings are possible in combination with a photovoltaic system and intelligent control technology.

Well-planned heat pump solutions also make for a secure investment, as they have long life cycles and require little maintenance. Since environmental energy is available at no cost, heat pumps afford the user greater independence from gas and oil market fluctuations. Their eligibility for public grants (Germany: BAFA and KfW) makes them yet more attractive.

Good partnership: where a perfect solution begins

Air, ground or water? Which heat pump system is best for a single-family house depends on many factors. It is not just the size of the house and the budget that play a role, but also the location and size of the property. With our products and planning tools, we can assist you in finding the perfect solution, taking all of these aspects into account.

Your basis: excellent technology

At Vaillant you will find everything you need for the planning and realisation of a heat pump solution. We offer you a broad range of heat pump technology — including hybrid systems in combination with state-of-the-art gas condensing technology.

Comprehensive solutions for self-generated power are part of this spectrum, as are intelligent control technology and smart interconnection. Our ventilation systems ensure consistently good air quality even in houses with tightly insulated building envelopes, thereby Preserving the value of the property. We additionally provide all-round support for the entire life cycle of your project — from the planning and start-up phases to ongoing maintenance.

Your added value: tailor-made services

With our customer-oriented planning tool, planSOFT, you can conveniently lay out your own heat pump system and calculate its energy efficiency. Once the solution has been implemented, we will help you on request at the initial system start-up. And with our warranty, you can offer your customers powerful arguments for a long-term maintenance contract: enhanced safety and an extended product warranty.

Sustainable comfort for every requirement

Flexible use of environmental heat: flexoTHERM exclusive, uniSTOR exclusive and auroPOWER

The ground source heat pump flexoTHERM exclusive wins customers over with its highly efficient and pleasantly quiet operation. Because it is based on an innovative concept, it can be flexibly expanded: into an air source heat pump by means of the air collector aroCOLLECT, and, with the groundwater collector fluoCOLLECT, into a water source heat pump.

The PV system generates part of the electricity necessary for operation using the new auroPOWER photovoltaic modules. Excess self-generated power is saved in the eloPACK battery storage device for utilisation during lower-yield periods. For water heating, choose the uniSTOR exclusive VIH RW, with up to 500 litres storage capacity and efficiency class A.

Flexibility in its most compact form: flexoCOMPACT

The flexoCOMPACT gives your customers the same flexibility in the choice of environmental energy — along with high hot water comfort using a minimum of space: it comes with an integrated 185-litre stainless steel storage cylinder. Both heat pumps bear the Green iQ label for their combination of sustainability and intelligent interconnection options.

Peak performance for low-energy houses: geoTHERM 3 kW

For low-energy and passive houses in particular, the compact, wall-mounted ground source heat pump geoTHERM 3 kW is the top choice. In combination with the space-saving hydraulic tower uniTOWER, this smallest model in the Vaillant range provides perfectly fitted heating and hot water comfort.

Important for heat pump solutions in new buildings

  • Environmentally friendly, efficient heat pump systems
  • High flexibility in the choice of environmental heat
  • Higher efficiency through the use of photovoltaic energy
  • Eligible for KfW and BAFA funding

Low-cost heat from the air: aroTHERM and uniTOWER

Simple outdoor installation, low power consumption and an active cooling function for summer: the air source heat pump aroTHERM delivers all-round comfort for the single-family house at a strikingly low price. You can additionally save considerable space in the cellar with the compact interior unit: a 190-litre storage cylinder and the components needed for heating operation are already integrated in the hydraulic tower uniTOWER.

Energy efficiency, intelligently regulated: multiMATIC 700 and VR 920

As variable as the configuration of a Vaillant heat pump system may be, controlling the system is child’s play. It is handled by the multiMATIC 700 system controller, which, for example, enables the automatic regulation of switching times on the basis of energy balance calculations. When used in conjunction with the flexoTHERM exclusive or the flexoCOMPACT exclusive, energy efficiency classes A++ to A+++ can easily be achieved. Thanks to the internet communication module VR 920, all of the important settings can also be made via app while on the go.

Fresh air, with ease: recoVAIR

Because regulations for new construction are leading to ever-more-tightly insulated building envelopes, a ventilation concept is required by law in new buildings. Our central ventilation system recoVAIR gives you full freedom in planning and layout, thanks to its comprehensive air duct system. The result: controlled air quality, for greater living comfort and the maintenance of the condition of your property.
