Heat Pumps Today

Industry proven to maximise heat recovery, reduce maintenance and lower running costs, Hydratech’s Thermox DTX heat transfer fluid with antifreeze function, is specified by the UK’s most prominent heat pump contractors, installers and designers. Thermox DTX: At the heart of the UK’s leading heat pump projects Key considerations when selecting a heat transfer fluid (HTF) for heat recovery include, e cient thermal energy transfer, antifreeze performance, minimal pumping-energy consumption, long-term preservation of pipework/ system components, cost and minimal environmental impact. Thermox DTX’s higher thermal conductivity and lower dynamic viscosity, results in increased heat transfer e ciency and heat recovery, its low viscosity reduces pumping energy consumed. Commissioned in thousands of commercial and domestic heat pump systems, by industry leaders such as Kensa, Nu-Heat and Ideal, the innovative fluid provides freeze protection down to -50°C, and less volume is required to achieve the same freeze-point protection - when compared with alternative thermal fluids. To prevent internal corrosion, scaling and biological fouling, Thermox DTX is formulated with long-life inhibitors which exceed ASTM D1384 standards. Classified as non-toxic and food-safe, the Hydratech product is readily biodegradable (90% over ten days) and will not remain in the environment or bio-accumulate. Utilising heat from wastewater Hydratech, the UK’s leading formulator of hybrid glycols and specialist heat transfer fluids have just completed their work on a turn-key heat pump project that will be capable of producing 12% of the UK’s tomatoes. 26 A D V E R T O R I A L Preparing to charge the heat pump systemwith Thermox DTX Picture credit: Oasthouse Ventures Low Carbon Farming’s mega-greenhouse projects in Norfolk and Sušolk, a world- first for renewable heating has 70 acres of greenhouse growing space, five times more glass than the Shard and over 10km of underground pipeline. Heat is extracted from nearby wastewater treatment plants and transferred in a closed loop system to the heat pumps located at the greenhouses. Electricity for the ground source heat pumps is provided by the grid and Combined Heat and Power units. Such ‘CHPs’ have the added benefits of providing waste heat which further supplements the greenhouse heating and providing carbon dioxide to enrich the atmosphere inside the greenhouse to encourage plant growth. The heat plate exchanger system extracts the heat energy using a water and Thermox DTX based system. A closed circuit then takes the heat transfer fluid directly up to the heat pumps. Specifically employed for the system, Hydratech’s Thermox DTX is a high e ciency, non-toxic geothermal heat transfer fluid with antifreeze function, for use in geothermal, GSHP & air source heat recovery systems. The carbon footprint of the food produced at the sites is expected to be 75% lower than equivalent European greenhouses, and 10 times more productive than field farming. The East Anglian sustainability projects demonstrate how renewable heating systems (heat pumps in particular) can be deployed on a commercial scale.
