Reading heat pump manufacturer Heliotropic Heat Systems raises £210k

A funding round of £210k has been completed by Heliotropic Heat Systems Limited, valuing the Reading, Berkshire-based business at £2m. This investment brings the total capital raised by the firm during 2026 to £235k.

The company manufactures quiet, space-efficient, fanless, and roof-mounted heat pumps designed specifically for the net-zero new build housing market within the United Kingdom. This technology addresses common noise and placement constraints associated with traditional equipment.

Incorporated in December 2025, the business filed formal documentation in June following an allotment of shares earlier that month. Financial records indicate the company's accounting year-end is 31 March 2027.
