Scientific studies

Measurement of the heat output of the partial storage heater (TU Dresden)

As part of a joint study by TU Dresden and LUCHT LHZ Elektroheizung GmbH & Co. KG, the scientists carried out a metrological analysis to determine the proportions of heat dissipated by convection and radiation in a partial storage heater. To do this, they designed a test rig concept and implemented it in the indoor climate room of the Combined Energy Lab at TU Dresden. They then carried out stationary tests under various load conditions. Using the measurement data obtained, they calculated the radiation and convection heat flows of our partial storage heater.

The result: approx. 41 % of the heat dissipation in the entire room is caused by radiation and approx. 59 % by convection – regardless of the load conditions of the partial storage heater.

Study: Evaluation of the potential of infrared heating systems to cover peak loads (TU Dresden)

The industry association IG Infrarot commissioned a study in which scientists at TU Dresden investigated whether an existing water-bearing heating system with high flow temperatures (i.e. a conventional oil or gas heating system) can be upgraded for operation with a heat pump at low temperatures by combining it with an infrared heating system.

The result: Prof. Dr.-Ing. habil. Joachim Seifert, Head of Building Energy Technology at the Institute of Energy Technology at TU Dresden, summarises the results as follows: “Heat pump systems in combination with electric infrared heaters represent a technological option for old buildings. The fulfilment of the heating task and thermal comfort can be guaranteed with this system combination.”

Study: Comparison of an air-to-water heat pump system with an infrared system

Prof. Dipl.-Ing. Timo Leukefeld et. al. compare infrared heaters with air-to-water heat pump heating systems based on the following criteria:
1. operating principle
2. grey energy
3. electricity consumption
4. total costs

The result: A heat pump heating system has significantly higher grey energy for production and disposal than an infrared heating system. Heat pumps require less electricity to operate, Nevertheless, the infrared variants 1b (heating with ceiling infrared panels and electric hot water boiler) and 2b (heating with ceiling infrared panels and electric hot water boiler in combination with a PV system with a nominal output of 10 kW and a battery system with a capacity of 10 kWh) are more economical than the heat pump variants 1a (heating and hot water preparation with an air-to-water heat pump) and 2a (heating and hot water preparation with an air-to-water heat pump in combination with a PV system) when comparing the systems. The service life of the heat pump is shorter than its static amortisation period (35 and 47 years respectively). Amortisation is therefore impossible. The required technical area of the variants is around 2 m² less if the heat pump can be omitted.

Independent tests of our electric radiators

Testing energy consumption at specified temperatures (SLG)

The testing experts at SLG Prüf- und Zertifizierungs GmbH (SLG) tested the energy consumption of our electric heaters at an ambient temperature of 5 °C and a room temperature of 21 °C with an air exchange rate in the test chamber of 1.0/h.
