High temperatures

The technology delivers high temperatures (50-80℃) and is suitable for radiators.

No outdoor unit

The system has no outdoor unit and extracts heat from the outside air through air ducts.

Installation

Retrofit your gas boiler in 1 day

The Turbine heat pump is the 1-to-1 replacement for the gas boiler and can be directly connected to the existing heating and hot water pipes. The installation can be completed in 1 day by any technician (no F-gas/STEK certification required). A high output capacity of 20kW provides high thermal comfort in any home.

Technology

Reverse Brayton cycle for sustainable heating in homes

The technology is based on the reverse Brayton cycle. This cycle has been used in aviation for decades, but Tarnoc is the first to successfully apply the technology in a heating device for homes and buildings. The patented technology uses outdoor air as a refrigerant and can heat (tap) water up to 80℃, even at very low outside temperatures of -10℃.

Our customers

Our customers consist of housing associations, municipalities, and companies that are testing the Tarnoc Turbine heat pump (prototypes) in different types of homes and buildings.

Pilots

The tests are conducted in various buildings such as terraced houses, national monuments, school buildings, and historic inner-city homes.

Frequently Asked Questions (FAQ)

Tarnoc is a startup founded by co-founders and former TU Delft students Tijmen de Jong and Vincent Wijdeveld, who have developed a new heat pump technology to achieve accessible sustainable heating for everyone.

The Turbine Heat Pump is a high temperature heat pump that extracts heat from the outside air without an outdoor unit. The all electric Turbine Heat Pump is developed to replace gas boilers in 1 day. This provides a scalable solution to heat existing homes sustainably and energy-efficiently. Most gas boilers cannot be easily replaced by a heat pump due to differences in capacity, temperature, and ease of installation.

The Turbine Heat Pump is still in development and is not yet available. The first prototypes have already been tested in various homes, and in the upcoming winter season (2024-2025), we will test the new generation of prototypes in various buildings: homes, commercial buildings, and historical properties.

A centrifugal compressor driven by an electric motor draws in outside air through the air intake and compresses the air. The compression generates heat to warm the water up to a maximum of 80°C. The energy from the compressed air is then recovered via the turbine. Finally, the cold air exits the home through the air outlet.

No, the Turbine Heat Pump does not have an outdoor unit and consists of only an indoor unit. Thus, there is no concern about noise disturbance for neighbors or the appearance of the home. The Turbine Heat Pump is particularly suitable for national monuments where the use of an outdoor unit is usually not permitted.

The Turbine Heat Pump is specifically developed to replace the gas boiler one-to-one in existing homes. The Turbine Heat Pump can be directly connected to the existing heating and hot water pipes. Like the gas boiler, the Turbine Heat Pump can heat water to high temperatures and continuously produce hot water. It is highly suitable for homes with a high-temperature water-based heating system like radiators.

The Turbine Heat Pump has a projected SCOP of 2, where the outdoor temperature has relatively little influence on efficiency and output capacity. Even at low outdoor temperatures of -10°C or colder, it can heat water up to 80°C with a capacity of 20 kW. The ability to selectively heat (night setback) allows the home to be heated quickly and efficiently when there is a demand for heat.

You can use the following calculation method to estimate electricity consumption. In this example, the annual average gas consumption of a household in the Netherlands is calculated: 1,200 m3 and a target SCOP of 2 for the Turbine Heat Pump.
· Calculation method to calculate gas (m3) to kWh: 1 m3 (natural gas) = ​​9.769 kWh
· Average efficiency of an (older) HR combi boiler is 85% and the Turbine Heat Pump with a target SCOP of 2 (=200%).
· Calculation example (gas to electricity Turbine Heat Pump) with a gas consumption of 1,200 m3 per year: ((1,200 x 0.85) x 9.769) / 2 = 4,982 kWh per year.

A three-phase (3x25A) connection is required. The fixed costs for a three-phase (3x25A) connection are generally the same as a standard single-phase (35A) connection. The grid operator will charge a fee to adjust the connection, and you can inquire about this with your grid operator.

Yes, the Turbine Heat Pump can continuously produce hot water for showering, similar to a gas boiler (CW3). For buildings with high hot water demand, such as hotels and sports clubs, the technology offers the ability to efficiently produce large volumes of hot water entirely electrically and buffer it in water boilers.

The Turbine Heat Pump operates at outdoor temperatures of -10°C or lower with almost the same efficiency and capacity to heat water up to 80°C. This is in contrast to traditional heat pumps, whose capacity and efficiency significantly decrease at low outdoor temperatures.

The Turbine Heat Pump has a modulating output capacity between 8-20 kW, providing an alternative to the gas boiler for a wide range of homes and buildings.

The Turbine Heat Pump is particularly suitable for existing ground-level homes built before the year 2000 with an energy label B/C or worse. The Turbine Heat Pump is suitable for heating terraced houses, detached houses, and historic buildings.

Just like the gas boiler, the Turbine Heat Pump also works in combination with underfloor heating, but less efficiently. The Turbine Heat Pump technology is efficient at higher temperatures 55-80 degrees Celsius and underfloor heating works at lower temperatures. Homes that are equipped with a low-temperature water-based delivery system (underfloor heating) as main heating can usually be heated more efficiently with a low-temperature heat pump.

For well-insulated (new build) homes with an energy label A or better, equipped with a low-temperature heating system (such as underfloor heating), heating can generally be more efficient with a low-temperature heat pump.

Apartments (flats, etc.) with a separate gas boiler for each apartment are generally less suitable. Often, the space is too small to accommodate the Turbine Heat Pump and air ducts.

Yes, the technology scales well to higher capacities. It is also possible to create setups with larger capacities by placing 20 kW Turbine Heat Pumps in a cascade layout.

The Turbine Heat Pump uses outdoor air as a 100% natural refrigerant. This is in contrast to most other heat pumps and air conditioners, which primarily use chemical refrigerants (e.g., R32, R410A, etc.) that are very harmful to the environment in terms of greenhouse gasses. From 2030, the use of these chemical refrigerants will be restricted by the EU, and they will eventually be completely replaced by natural refrigerants.

Yes, the energy generated by PV panels can be offset against the electricity consumption of the Turbine Heat Pump via the net metering scheme (Salderingsregeling).

The technology is less suitable for cooling buildings. Other solutions are better suited for this purpose. Effective cooling of a space requires condensate drainage, which is not possible with radiators present in most buildings.

The expected dimensions are a floor area of 60×60 cm and a height between 120-150 cm. The air ducts (inlet and outlet) have a diameter of approximately 25 cm and must be connected to the outside air via a roof or wall vent.

The noise level of the Turbine Heat Pump will be comparable to a gas boiler and is entirely vibration-free.

The Turbine Heat Pump is initially developed for water-based heating systems and is not suitable for directly heating air.

Insulating is always worthwhile as it will reduce the heating demand of the home. The advantage of the Turbine Heat Pump is that insulating measures can be implemented afterward.
