Hi,
the heat pump must be in operation.
The funding amount depends on the type of heat pump, i.e., geothermal or air. For air, a certain annual performance factor must be achieved.
Supplement according to bafa
Funding of efficient heat pumps
Application procedure
The application must be submitted within 6 months after the system is put into operation. Eligible projects are those that started from October 16, 2006, and are completed at the time of application.

Requirements for funding efficient heat pumps
Eligible are efficient heat pumps for combined domestic hot water preparation and provision of the heating demand of a building that meet the following requirements:
[*]For electrically driven heat pumps: Installation of an electricity meter and at least one heat meter to measure the largest heat quantity of the system. From July 1, 2009, measurement of all heat quantities delivered by the heat pump will be mandatory. If necessary, several heat meters must be provided. The date of receipt of the application at BAFA is decisive.
[*]For gas-engine-driven heat pumps: Installation of a gas meter and at least one heat meter to measure the largest heat quantity of the system. From July 1, 2009, measurement of all heat quantities delivered by the heat pump will be mandatory. If necessary, several heat meters must be provided. The date of receipt of the application at BAFA is decisive.
[*]Existence of a specialist contractor declaration with the following content:
[*]
[LIST]
[*]For electrically driven heat pumps: Proof of an annual performance factor (JAZ) of at least 4.0 for brine/water and water/water heat pumps in new buildings or at least 3.7 in existing buildings, for air/water heat pumps at least 3.5 in new buildings or 3.3 in existing buildings.
[*]For gas-engine-driven heat pumps: Proof of an annual performance factor of at least 1.2.
[*]Proof of hydraulic balancing of the heating system.
[*]Proof of adjustment of the heating curve of the heating system to the respective building.
The annual performance factor for electrically driven heat pumps is the result of dividing the delivered heat quantity by the electricity consumption including the electricity used for the operation of peripheral consumers, in particular the groundwater pump, brine circulation pump, emergency heating element, and control system.
From July 1, 2009 (the date of receipt of the application at BAFA is decisive): The annual performance factor must be determined according to the then current version of VDI 4650 (2009) taking into account the annual performance factors for space heating and domestic hot water. It corresponds to the total annual performance factor according to VDI 4650 (2009).
The calculation basis must be attached to the application using the corresponding BAFA forms.
For the use of heat pumps operated with fossil fuels, the energy content of the used energy including the electricity used for the operation of peripheral consumers, especially the groundwater pump, brine circulation pump, emergency heating element, and control, must be taken into account.
Before July 1, 2009 (the date of receipt of the application at BAFA is decisive), the calculation method is as follows: The COP value required for calculating the annual performance factor is to be determined according to DIN EN 255 or DIN EN 14511 for air/water heat pumps considering the normative media temperatures A-7/W35, A2/W35 and A10/W35, for water/water heat pumps considering normative media temperatures W10/W35, and for brine/water heat pumps considering normative media temperatures B0/W35. In existing buildings, a heating flow temperature of 55 °C and a heating limit temperature of 15 °C must be assumed unless lower values can be demonstrated.
If for special types of heat pumps no standardized procedure for calculating the annual performance factor is available, funding can still be granted. In these cases, compliance with the required minimum annual performance factor must be credibly demonstrated in a comprehensible calculation. This determination of the expected annual performance factor must be submitted with the application to the funding agency for review.
If heat meters cannot be installed in direct condensation heat pumps due to constructive circumstances, funding can be granted if a heating flow temperature of no more than 40 °C is not exceeded and credible and comprehensible proof is provided that the required annual performance factors are achieved under realistic conditions. Separate recording of the electricity or gas consumption of the heat pump remains a prerequisite for funding.
The funded systems will be randomly checked within the framework of a special evaluation program.
Funding amount for efficient heat pumps
Basic funding
Existing buildings
The basic funding for heat pump systems in existing buildings, except air/water heat pumps in residential buildings, amounts to 20 euros per square meter of living space and 20 euros per square meter of heated usable space in non-residential buildings. The funding for residential buildings is limited to a maximum of 3,000 euros per dwelling unit. For residential buildings with more than two dwelling units and for non-residential buildings, the funding is limited to 15% of the proven net investment costs for the heat pump system.
For air/water heat pumps in existing buildings, the funding is 10 euros per square meter of heated living space and 10 euros per square meter of heated usable space in non-residential buildings. The funding for residential buildings is limited to a maximum of 1,500 euros per dwelling unit. For buildings with more than two dwelling units and for non-residential buildings, the funding is limited to 10% of the proven net investment costs.
New buildings
The basic funding for heat pump systems (except air/water heat pumps) in newly constructed residential buildings for which a building application was submitted, or notification was made, before January 1, 2009, amounts to 10 euros per square meter of living space in residential buildings and 10 euros per square meter of heated usable space in corresponding non-residential buildings. The funding for residential buildings is limited to a maximum of 2,000 euros per dwelling unit. For residential buildings with more than two dwelling units and for non-residential buildings, funding is limited to 10% of the proven net investment costs for the heat pump system.
For air/water heat pumps in newly constructed residential buildings for which a building application was submitted, or notification was made, before January 1, 2009, the funding is 5 euros per square meter of living space in residential buildings and 5 euros per square meter of heated usable space in corresponding non-residential buildings. The funding for residential buildings is limited to a maximum of 850 euros per dwelling unit. For residential buildings with more than two dwelling units and for non-residential buildings, funding is limited to 10% of the proven net investment costs.
The basic funding in newly constructed buildings for which a building application was submitted, or notification was made, after December 31, 2008 is reduced by 25% of the funding amounts. The funding limits are reduced accordingly.
Note: Proof of living and usable space is provided by appropriate documents (e.g., floor plans, purchase contracts, etc.). If there are additional heat generators in the building besides the heat pump, only the area proportion attributable to the heat pump is funded.
Bonus for combination with solar collector system
If a solar collector system funded under these guidelines is installed at the same time, a combination bonus of 750 euros can be applied for together with the solar application.
Separate applications must be submitted for both measures.
[B]Efficiency bonus[/B]
For heat pump systems in efficient buildings, which achieve lower cost savings for fossil fuels due to lower primary energy demand when using renewable energies and this is evidenced by an energy performance certificate, higher funding can be granted.
Efficient within the meaning of this regulation are buildings that meet special requirements for the specific transmission heat loss or transfer coefficient (HT´) referring to the heat-transferring envelope area, namely for residential buildings according to § 3 paragraph 2 in connection with Annex 1 Table 1 and for non-residential buildings according to § 4 paragraph 2 in connection with Annex 2 Table 2 of the Energy Saving Ordinance (EnEV) in the respectively applicable version.
For level 1 of the efficiency bonus, it is required that buildings with building permits before 1995 do not exceed these values or that buildings with building permits after 1994 fall below these values by at least 30%.
For obtaining level 2 of the efficiency bonus, it is required that buildings with building permits before 1995 fall below these values by at least 30%, or buildings with building permits after 1994 fall below these values by at least 45%. Level 2 of the efficiency bonus can also be granted for heat pump systems if an annual performance factor of at least 4.5 (existing buildings) or at least 4.7 (new buildings) is demonstrated and the building simultaneously meets the conditions of level 1.
For efficiency funding at level 1, the amount of funding (basic funding plus efficiency bonus) is 1.5 times the basic funding. For level 2 efficiency funding, the amount of funding (basic funding plus efficiency bonus) is twice the basic funding.
Bonus for particularly efficient circulation pumps
If a particularly efficient circulation pump is installed simultaneously with a heat pump system, a bonus of 200 euros per heating system can be granted.
The circulation pump must be part of a hydraulically and regulation-optimized heating system equipped with presettable thermostatic valves on the radiators and, if applicable, further balancing valves.
Particularly efficient circulation pumps are pumps that meet the requirements of the voluntary energy label class A of the pump manufacturers.
The bonus for the particularly efficient circulation pump must be applied for together with the funding of the heat pump system. The installation of the particularly efficient circulation pump must be proven by invoice from a specialist company and must be listed in the specialist contractor declaration.
Innovation funding for particularly efficient heat pumps
For systems in new buildings, if an annual performance factor of at least 4.7 and in existing buildings an annual performance factor of at least 4.5 is demonstrated, the funding rates and funding limits increase by 50%.
The combination bonus, efficiency bonus, and innovation funding are each mutually exclusive and cannot be combined with each other.
