Heat pump boiler

When installing heat pump boilers, it is essential to take into account the following points or to have possible effects clarified by a specialist:

• Sound level: This is especially to be considered if the installation room is located near bedrooms and living rooms.

• Room cooling: The installation room is cooled by the heat extraction and should include at least 20m3 room volume.

• Heat extraction: A heat extraction takes place in the installation room and indirectly through walls and ceilings, if the installation room is located within the thermal envelope. An installation in unheated, insulated rooms reduces the heat extraction and thus the indirectly consumed heating energy in the winter half-year. In summer, this heat extraction is perceived as cooling.

• Only new, state-of-the-art plant and plant components and equipment are to be used.
• The hot water preparation has to be done primarily with the subsidized home automation system, thermal solar collectors or a heat pump boiler. Pure electric boilers are not permitted in subsidized systems.
• Electrically operated pipe trace heating and hot water circulation systems are to be connected with a timer, ideally via an all-pole disconnection point (socket). This is because pipe trace heating systems are large consumers of electricity and should be operated in a targeted manner. If there is a disconnection point (socket), a consumption measurement can be made and quite simply unplugged in the event of unnecessary operation / service.
• For hot water circulation circulating pumps energy efficiency class A (EEI ≤ 0.23) are to be installed. When installing a circulation pump that does not meet the energy efficiency class A (EEI ≤ 0.23), the subsidy is reduced by CHF 300.- per pump.
• Heat pump boilers with a COP of at least 3.2 according to EN 16147 at test condition A20/W10-55 are to be installed.
• The heating and the hot water systems shall be provided with continuous thermal insulation, including all distribution lines. The minimum insulation thicknesses are to be taken from the following table:

Not subsidized are building services systems, if they serve as an auxiliary heating to an inherently sufficient (monovalent) heating. Decisive in the promotion is the type of home automation system and the size of the building object.

Forfeiture of the claim The entitlement to the payment of subsidies expires if the measures are started before a legally binding assurance of the subsidies has been received.

Recontribution Funding contributions are only paid once for each measure; renewed funding of the same measure is only possible after 20 years.

Project author Subsidies will only be paid if expert planning and execution of the measures is ensured.

Term The assurance of the subsidy is limited in time according to Art. 25 EEG. The measure must be started within one year from the decision on granting subsidies and completed within two years.

Swinging other regulations The measure is not subsidized if it  is mandatory due to other legal regulations according to Art 4. para. 2a) EEG (e.g. superstructure plan, air conditioning, swimming pool heating, conversion of use, etc.).
