Heating inefficiency in the UK

Biotherm stores and releases heat

  • PCM panels absorb and release heat naturally

  • Stabilises room temperature over time

  • Reduces reliance on mechanical heating

  • Made using waste streams

How to use Biotherm

Place multiple Biotherm panels where heat flux is greatest to improve room-wide temperature stability. Easy user installation, no building / experts needed.

How Biotherm Works

Biotherm combats the significant CO2 emissions from the home heating industry. PCMs naturally regulate heat by absorbing and releasing heat, within a narrow thermal range (18°C - 20°C), as they melt and solidify (change phase). By reducing heat fluctuation and regulating room temperature, PCM insulation will lessen the demand for mechanical heating and cooling. This insulation technology is easy to apply to current housing stock to increase energy efficiency in older buildings as well as new. Biotherm will lessen the carbon impact of the heating industry and the Urban Heat Island effect, which is causing our cities to warm. Comprised of several waste streams and organic materials making biotherm a more sustainable solution.

Phase Change Material composition

Waste Oil from the food industry is mostly reused in the Bio-fuel industry. These have been found to produce more CO2 emissions than fossil fuels with the same energy output.

Paraffin wax is a bi-product of crude oil. This material is in abundance allowing PCMs to be produced mass market.

Assembly

Designed for Disassembly the bracket system enables the PCM to be removed, recycled an replaced independently at end of life. Extending product longevity, simplifying maintenance and supports circularity.
