GHT SIA – Innovation in Energy Efficiency and Sustainability

GHT SIA is a Latvian company with over a decade of experience developing energy-efficient solutions for residential and commercial buildings. Our flagship product, GHT (Geothermal Technology), is a next-generation pre-heater/cooler designed for HRV/ERV systems, significantly improving their efficiency and performance.

Innovation and Development

Over two years of intensive research and development leading up to 2014 enabled us to create a unique technology that is now at the heart of the GHT unit. Our team combines engineering expertise, practical experience, and a passion for sustainable solutions to deliver products that make a real difference in energy savings and CO₂ emission reduction. 

Technological Breakthrough

The GHT system represents a new generation of solutions. We evolved from traditional steel box construction to a fully thermal bridge-free EPP (expanded polypropylene) enclosure. This advancement has made GHT significantly lighter, better insulated, and more efficient, while maintaining a high level of safety and durability. Our products provide up to 8 kW of heating/cooling capacity with minimal electricity consumption (only 0.04 kW), making them among the most efficient on the market.
