CENPAC plus intelligent heat pump combination
The customised photovoltaic solution - now with reinforcements
The CENPAC 3.x with a performance of over 3 kWp is excellently suited to the installation on your detached or terrace house with a roof surface of at least 42.1 m². All that is required is a comparison of the CENPAC conditions of use – and off you go...
The classy complete system is delivered to your door fully pre-manufactured and ready for heat pump combination. The extensive documentation and the uncomplicated mounting enable unprecedented handling of the photovoltaic unit together with hot water support.
The hot water heat pumps BWP 30HS and BWP 30HSD from Dimplex use up to 70% of the waste heat in the ambient air as an energy source. The interaction with the CENPAC plus Heat-Shifter creates an intelligent symbiosis of regeneratively produced energy and hot water. The 300 l storage tank also ensures optimal provision of the power that has been generated.
- Hot water heat pump with LC display
- Time-controlled legionella protection programme
- Quick heat button for larger quantities of tap water
- Shapely design
- Digital control enables the combination with the CENPAC energy manager.
- Intelligent heating by increasing the target temperature of the hot water with a
maximum PV output.
A strong team that pays off
With the use of the hot water heat pump with intelligent control, you will increase the own consumption share of your CENPAC 3 x depending on the number of persons in your household.
Based on a typical 4-person household with an energy requirement of 4,000 kWh/year, the added effect of additional own PV consumption, costs saved on energy procurement and the costs of providing hot water are clear.
Thanks to the use of environmentally-friendly regenerative energy for providing hot water, the intelligent combination also offers an efficient solution for optimizing your energy balance both in new and existing buildings.

More details
This is how it works
The CENPAC plus Heat-Shifter is connected between the inverter and the heat pump and regulates their interaction.
Based on the location, the day of the year, alignment and roof pitch, it carries out a current assessment of the upcoming PV performance.
This is how the optimal time is determined for activating the increase in the target temperature of the hot water in the heat pump tank.
- Higher fee for increased on-site consumption
- Cost savings in providing hot water
- Improving the building energy balance
