Cleverly combined – designed with the future in mind
Heat pumps are becoming increasingly common in new-build homes. The only downside? Their efficiency drops at low temperatures. BRUNNER, the premium manufacturer from Lower Bavaria, now offers a smart solution: the new BWP 4/14 green heat pump. It uses an eco-friendly refrigerant and delivers higher performance at lower operating costs.
Combined with a water-bearing wood-burning appliance, it becomes a truly unique and forward-thinking heating system.
The heat pump
outside of the concept
An air-source heat pump extracts thermal energy from the outside air, converts it into heat, and feeds it into the building’s heating system. It’s a CO₂-neutral and environmentally friendly solution. The system operates most efficiently at outdoor temperatures between 2 and 15 °C. But when temperatures drop significantly in winter, efficiency declines. In really cold conditions, relying solely on a heat pump isn’t ideal — it can quickly become a power-hungry system. To prevent the building from cooling down, an electric heating element kicks in to cover the shortfall in heat for both space heating and hot water — but this requires a large amount of electricity, which comes at a high cost.
The advantages of the heat pump and stove heating combination
Combine your heat pump system with a water-bearing stove or fireplace and enjoy the atmosphere of real wood fire while simultaneously producing hot water for your heating system.
Sustainable heating with renewable energy – saving electricity, protecting the environment, and bringing cozy firelight into your home.
A heating concept with two heat sources working hand in hand to reliably deliver warmth to your home at all times. That’s something you can count on.
The unique
system solution
Heat pump combined with a water-bearing stove
To prevent a heat pump from consuming excessive electricity during freezing temperatures, combining it with a water-bearing wood-burning appliance is an ideal solution to reduce peak load demands.
What makes this setup truly unique is its intelligent, electronically controlled system: the heat pump detects when its efficiency drops due to low temperatures. A control display shows when to fire up the water-bearing stove or fireplace.
This appliance heats water for the heating system, feeds it into a buffer tank, and ensures a consistent indoor temperature – even on the coldest days. The heat pump is relieved, as the entire system is perfectly synchronized both hydraulically and in terms of control logic. The result? A longer lifespan for the heat pump and the added bonus of a cozy wood fire atmosphere.
Product selection: heat pump +
water-bearing stove/fireplace + control unit
The minimum product requirements for this heating concept include a heat pump, a water-bearing stove or fireplace and a control unit. The system can be optionally expanded with additional components as needed.
System units as a fast and more cost-effective alternative
For a quick and budget-friendly solution, we offer system fireplaces and stoves in a variety of glass pane formats. The great thing about these water-bearing system units: they can be assembled and connected by a heating installer.
However, if you’re aiming for a custom fireplace design, it’s best to work with a professional stove builder. They can create a unique exterior tailored to your exact preferences – perfectly suited for water-bearing fireplaces and stoves.
The heat pump heating system Plus -
a future-ready heating concept
The true benefits of a heat pump come into play when all heat sources and consumers within a building work together as one integrated system.
At BRUNNER, we call this approach the Heat Pump Heating System Plus. It’s built around a large, central buffer tank designed as a stratified storage system. This tank collects and stores the energy generated by the heat pump, a water-bearing wood-burning appliance, or other heat sources – and distributes it as needed to the heating system.
The buffer tank and hydraulic unit are specially designed to match the performance and control requirements of the BRUNNER heat pump. Heat producers and consumers simply need to be connected. The system can handle up to six heating circuits – for example, wall heating, radiators, or underfloor heating.
All hydraulic components come pre-installed and fully synchronized – including the control logic for the eco-hierarchical use of renewable energy sources.
