Heat pump with integrated storage cylinder

Newly built detached house

The typical prefabricated house with good thermal insulation and no basement offers enough space for a family of three. But the space, especially for the building services, is limited.

Modern heating means using environmental heat

Stefanie and Andreas have opted to buy a prefabricated house on a new housing estate on the edge of town. It is clear that the only choice for the young parents is a heat pump heating system using the ambient air as a heat source.

A good future for little Noah

Stefanie and Andreas have lived in a rented apartment in the centre of town for many years. But six months ago, little Noah came along. Now it is time for the couple to plan a child-friendly home in the country. They found a wonderful plot very quickly. The housing development is ideally situated and nice and quiet.

The plot and 130-m² prefabricated house made by a major provider are suitable for the family’s tight budget. It is important to Stefanie and Andreas that their house meets high energy efficiency standards and uses a heating system that runs without oil or gas.

What to do when space is limited?

But which type of heating system meets these requirements in a typical new building without a cellar and equally little space in the utility room? Stefanie is a physics and geography teacher so she realises straight away that their only option is an air-to-water heat pump heating system. The alternative choice of biomass heating is worse for the environment and fuel storage would simply take up much too much room.

Reasons for choosing a heat pump centre & mechanical ventilation

While researching their project, Stefanie and Andreas were immediately taken with the advantages provided by a heat pump centre. This compact solution with an integrated storage cylinder is just right for them. They also decide to install a ventilation unit to improve the indoor environment still further.

03. No fossil fuels

The family decides to equip their house with a heat pump centre. After all, these use no fossil fuels. The heating system utilises the freely available outside air to warm the house’s interior to a pleasant temperature and produce hot water.

04. Pleasantly cool in summer

Andreas remembers the hot spells of recent years only too well. On some days, it got unbearably hot in their apartment, even in the evening. So he is even more pleased by the ability of a heat pump heating system to cool the interior of the new house during the summer.

05. Pristine air quality

Stefanie has suffered from allergies all her life. So she is looking forward to controlled mechanical ventilation that continuously supplies fresh air while keeping pollen, other allergens and pollutants outside. Stefanie also knows that ventilation with heat recovery reduces energy consumption and saves money in the long run.

Product solutions for the modern prefabricated house

From the huge range of products available, the family decides on WOLF equipment because the company supplies both heat pump and ventilation systems. The appliances also have sleek designs and comply with the latest technological standards.

CHC monoblock with storage cylinder

The outside module of the WOLF CHC monoblock works particularly quietly thanks to fan blades that emulate owl wings.

It uses the natural refrigerant R290 (GWP 0.02 according to IPCC AR6), which does not deplete the Earth's ozone layer. The interior module contains an integrated hot water storage cylinder, which saves space and looks smart.

CWL-2 mechanical ventilation unit

The WOLF CWL-2-225 can recover the indoor heat. This saves a huge amount of energy.

Stefanie and Andreas are impressed by the automatic filter change display on the appliance. Even better, the filter can be changed without needing any tools.

Support for Your Home Project

Choosing a heating, ventilation or energy system for a home can involve a range of technical and project-related considerations. WOLF provides information and planning resources to support the assessment of different system options and project requirements.

Good for the climate, good for your budget

In combining a heat pump with a home ventilation system, Stefanie and Andreas are confident that they are investing in an efficient and, therefore, economical heating system for their family home. Furthermore, it will ensure that their indoor climate is well-balanced and pleasant.

The family also definitely want to use solar power in the future once they can afford it. They are intending to purchase a photovoltaic system as they are easy to retrofit. They will also be able to use the solar electricity to run their heat pump heating system which will reduce the power consumption of their home and so improve the cost-effectiveness of the photovoltaic system. Their goal of a heating system that burns no fuel in the house is achieved.
