Living sustainably and affordably – the two can be reconciled
For a good while, it has been possible to tailor prefabricated houses to the owners’ specific desires. Tanja and Philip Brun’s story is a good example of this. The couple realised their dream of having their own sustainable and affordable home with a prefabricated timber frame: 162 m² of comfortable living space that meets the KfW 40 Plus efficiency standard.
The challenge
The heating system needed to be sustainable and economical to run. A high seasonal energy performance ratio (SEPR) was equally important. Since all of the building technology was to be installed in the outbuilding, being economical with space was a top priority.
The solution
The Bruns opted for an all-in-one system solution from Vaillant. A recoCOMPACT exclusive air-source heat pump, entirely installed indoors, provides the house with environmentally friendly domestic heating, hot water and fresh air. A 225 l hot water cylinder has an integrated ventilation unit. Tanja and Philip Brun have grown to appreciate its cooling function.
A large proportion of the operating current is supplied by the photovoltaic systems and battery storage. This keeps the operating costs low.
The air-source heat pump recoCOMPACT exclusive can be installed in just one day. At just 1.5 m², the space needed for the all-in-one system is relatively small: the Brun family can also use the 5 m² installation room to store gardening equipment.
The compactness of the site meant that noise emission was a very delicate topic: in night mode, the outside noise level 3 metres from the weather protection grid was below 35 db(A) – this is comparable with the ticking of a clock. There have never been any complaints from the neighbour even though the outbuilding is adjacent to their patio.
The air-source heat pump recoCOMPACT exclusive bears the Green iQ label, symbolising an especially energy-efficient, connected and sustainable product. The system can be intelligently managed using a free app. This means the environmentally minded family can feel good about enjoying maximum comfort.
Why choosing Vaillant is a good decision
Heating, cooling, ventilation and hot water all in one: a perfectly coordinated and energy-efficient system solution that creates comfort in the family home.
