Efficient gas condensing technology for the single-family house

Sustainable living comfort with gas condensing technology

Fulfilling expectations, complying with regulations

When building new family houses, the basic task is always the same: the heating system must be fit for the future, a sound investment, state-of-the-art and simple to operate. And ideally, eligible for subsidy.

Because many residential areas have a gas connection, making for comparatively low investment costs, a gas condensing solution is often the best option. In the planning process, however, it is becoming more and more difficult to find the perfect balance between technical and economic feasibility.

We live in an increasingly complex world in which ambitious energy-saving targets lead to stricter legal regulations. One result is that, in Germany, gas condensing technology can no longer meet the requirements of the Energy Saving Ordinance (EnEV) without sustainable system extensions. This poses the question of whether gas has any future in new buildings.

The future of gas: integrated solutions

Gas can be used highly efficiently in new construction: in combination with good building insulation and solar heating, modern gas condensing systems work extremely economically and reduce heating costs over the long term — without compromising comfort.

The addition of controlled living space ventilation with heat recovery not only enhances air quality and residents’ wellbeing, but also protects against mould formation, thus helping to maintain the value of the property. With the right combination of gas condensing technology, solar heating and ventilation, it is even possible to fulfil the standards required for a German ‘KfW Efficiency House’.

Your advantage: everything from a single source

Planning a modern gas heating system for a family home is a complex task. That is why Vaillant gives you everything from a single source: the latest gas condensing boilers and storage cylinders, sustainable solar heating, comfortable ventilation systems, intelligent regulation technology and connectivity as well as comprehensive support for your new construction project.

Always included: services for you and your customers

We support you as a partner, from the initial planning phase to ongoing maintenance. For example, planSOFT will assist you in laying out your solar or ventilation systems. And our warranty provides you with a persuasive case for a long-term maintenance agreement to present to your customers: increased safety and an extended product guarantee.

Using gas and solar energy with system solutions from Vaillant

Sustainable efficiency: ecoTEC exclusive and auroSTOR exclusive

State-of-the-art gas condensing technology and complementary solar heating: with this combination, gas remains fit for the future. Its high-performance heart is a gas condensing system of the latest generation. With ist high modulation range, the ecoTEC exclusive wall-mounted gas condensing boiler guarantees low consumption rates and offers smart interconnection.

For hot water comfort, you can additionally use the energy of the sun. The auroSTOR exclusive solar cylinder offers up to 500 litres holding capacity and impresses with its excellent insulation and digital temperature indicator. It draws the necessary thermal energy via the auroTHERM plus flat plate collectors — your customers’ efficient and premium-quality entry into solar energy.

Sustainability label: green iQ

We’re known for sustainability and connectivity. The ecoTEC exclusive and the auroSTOR exclusive bear the Green iQ label, which we award to environmental and intelligently interconnected products. Strict standards apply to the issuing of the label: high recyclability, energy-saving operation, long-lasting quality, efficiency class A or higher, and intelligent system technology.

Important in gas solutions in new buildings

  • Compact, space-saving gas condensing solutions
  • Simply meet German EnEV requirements through controlled ventilation of living space
  • Supporting solar systems to meet all needs
  • Eligible for KfW funding

A boiler with all the options: auroCOMPACT

Because every additional square metre in a new building means high costs, utility space is often kept to a minimum. Such situations call for compact solutions. The auroCOMPACT is a modern, compact and highly efficient gas condensing boiler. With its integrated stratified tank for heating water, it can also be easily be made into a fully-fledged solar thermal system: all the necessary solar components are already integrated. This makes the auroCOMPACT attractive to homebuilders seeking flexibility in financing.

Supported by either two or three flat plate collectors, the system can provide up to 68% of the energy needed for water heating, without additional cost. As a drain-back solar system, the auroCOMPACT VSC D with auroTHERM classic flat plate collectors can achieve especially high efficiency. Even in summer, these function stagnationfree, thus considerably reducing maintenance costs.

Energy-saving fresh air system: recoVAIR

Controlled living space ventilation fulfils strict German EnEV requirements while also offering you greater choice in building insulation. Our central ventilation system recoVAIR gives you full flexibility in air duct installation, saves energy through heat recovery and can be easily combined with other Vaillant components.

Multifunctional living comfort: multiMATIC 700

The multiMATIC 700 system controller, now also available in a wireless version, lets your customer control the entire system — via the VR 920 internet communication module and, for remote use, the free multiMATIC app.

Heating homes today with the technology of tomorrow: Vaillant Green iQ

Vaillant develops heating systems that promote the convenient use of renewable energy sources. The Ecodesign Directive ErP, which became binding in September 2015, defines the minimum requirements for energy-relevant products. It informs consumers about the efficiency of products and systems through the energy efficiency label. As a pioneer in energy-saving and environmentally friendly heating technology, Vaillant goes even further.. We use the Vaillant Green iQ label to designate products which not only use very little energy but are also intelligently networked – such as the ecoTEC exclusive and the auroSTOR exclusive. This means that you can plan and develop an individual heating system for your clients, which already meets the requirements of the future.
