FAQs

How does a heat pump work?

The heat pump uses refrigerant to extract energy from the outdoor air and transfer it to a higher temperature that can be used for your heating.

 

Why is an air-to-water heat pump the ideal investment for the future?

An air-to-water heat pump combines the advantage of low acquisition costs with extremely low operating costs and therefore makes efficient use of renewable energies.

 

Is a TOSHIBA heat pump eligible for funding?

TOSHIBA heat pumps have all the necessary certificates and requirements to make them eligible for funding. However, grants depend on the country, city, and on the local electricity supplier.

 

What does SPF stand for?

Seasonal Performance Factor is a measure of the efficiency of heating systems operated with heat pumps. It represents the ratio between the energy supplied (electricity) and the heat actually generated over the duration of one year and serves as a benchmark for cost-effectiveness calculations.

What is the life expectancy of a heat pump?

An air-to-water heat pump has the same service life as other conventional heating systems, which is ensured by regular maintenance and guaranteed 15-year spare parts availability.

 

How much space do you need for a heat pump?

The transfer station takes up 93x53x36 cm (HxWxD) of space, so the heat pump can be used even in small rooms.

Why is an electric backup heater required?

The certified heat pump partner will design the TOSHIBA heat pump in line with your building's requirements, so that the electric backup heater is only required for backup heating at the lowest outdoor temperatures.

 

Is the combination of heat pump/solar system or photovoltaics possible?

The integration of solar energy in combination with your heat pump is possible and can contribute to an increase in efficiency.

Can I use a heat pump for cooling?

In winter you can generate heat using your panel heating system and in summer you can use this to temper your room. Active cooling is possible via fan coil units.

 

Does the heat pump work even at minus temperatures?

Although the efficiency of the system decreases at a very low outdoor temperature, heat pumps are able to generate heat even from an outdoor temperature of -25°C.

How efficient is the heat pump in summer when I only need hot water?

As heat pumps work even more efficiently at higher outdoor temperatures, you can produce hot water temperatures of up to 55°C flawlessly and cost-effectively at outdoor temperatures of up to 35°C.

 

Up to what supply water temperature is it practical to operate a heat pump?

The lower the supply water temperature, the more energy-efficient the heat pump is. Supply water temperatures of max. 60°C are possible, but for radiators, 50°C is usually sufficient if they are in continuous operation.

How do you determine the correct power capacity of a heat pump?

The correct design determines the efficiency of the heat pump. For our systems, this is carried out using the performance table in order to ensure the required heating capacity of your building up to the standard outdoor temperature, without the use of the backup heater.

 

What can I control using the heat pump?

The heat pump has an intelligent control logic that independently regulates the heating temperature of the radiators, the underfloor heating, and the hot water depending on the outdoor temperature.

How easy is commissioning?

Due to ready-made installation diagrams and associated commissioning parameters, commissioning is a stress-free and quick task for the specialist. Using the step-by-step guide in the APPENDIX/manual or APP, each parameter can be adjusted to suit individual requirements.

 

What do I need to connect the heat pump to a building control system?

External control or integration into a building control system via KNX or MODBus is possible with additional PCBs.

Who do I contact if I have any questions?

Should a malfunction or problem occur in your system, the certified heat pump installer will be on hand to provide you with advice and assistance.

 

What does nominal capacity mean?

Nominal capacity is the unit capacity at a specified operating point.

 

What does heating limit temperature mean?

Daily mean temperature from which a building must be heated. Days on which the daily mean temperature is below the heating limit temperature are classed as heating days.

 

What does standard outdoor temperature mean?

The average lowest expected outdoor temperature for which your heating system is designed.

 

What is COP?

COP stands for Coefficient Of Performance and specifies the ratio of electrical energy used to thermal energy received at a given operating point.
