Hi-Therm® product validation

HI-THERM® Thermal Conductivity

Hi-Therm is a bespoke thermal fluid developed and manufactured in the UK by High Tech Systems that uses nanotechnology to enhance the thermodynamic properties of water. Plasma functionalisation and processing of nanomaterials have been successfully carried out, which produced a dispersion with improved thermal conductivity properties.

Samples of the processed thermally enhanced nano fluid were sent to a leading thermodynamics test facility for third-party verification of thermal conductivity results. The thermal fluid samples tested and independently verified by a third party showed an increase in the thermal conductivity value of greater than 37% when tested at 60°C and greater than 55% at 80°C, when compared to water.

Independent Testing

The samples of water-based dispersed thermal fluid were tested at three different temperatures: ambient, 60°C and 80°C using scientific recognised equipment to identify the thermal conductivity.

The results presented in Table 1 show a 37.7% increase in thermal conductivity when compared to water at 60°C. Thermal testing was also carried out at 80°C, which showed an even greater increase of 55.8% in thermal conductivity when compared to water.

Energy Savings

High Tech Systems are proud to announce that Hi-Therm has been tested by the National Centre for Gas Excellence in Pontefract, one of the UK’s leading test and training centres for gas engineers.

In a real time-controlled environment, two independent central heating systems were installed side by side consisting of a new boiler, new radiators and new gas meters. One system was filled with water and the other with Hi-Therm. Both boilers were set to a flow temperature of 80°C and were left to run for 24 hours. It was recorded that Hi-Therm used 31% less gas than water during this period.

Separately, real-world tests have also shown an energy saving using Hi-Therm compared to water. Independent thermal fluid simulations were undertaken in a test facility specialising in thermodynamics referencing British Standards Institution (2014) BS EN 442-1 and 442-2 Radiators and Convectors.

The simulations were based on heating a single bedroom in a domestic home for a period of one month. The tests showed a 31.7% difference at 60°C and a 43.7% difference at 80°C in kW/H.

Quoting the independent report: “In summary, the results would indicate in a real-world application, the system should be able to operate at a lower temperature and provide the same domestic heating output, thus saving energy.
