About RA Tech UK Ltd

RA Tech UK Ltd, market leaders and pioneers of the award-winning hotun dry trap tundish concept and creating solutions to some common industry problems, saving installers up to 3 hours of their time when installing a boiler on an internal wall by using a hotun and helping to save water and energy by highlighting if things start to go wrong, not to mention saving money all round on shorter pipe runs.  All products are fully compliant and fully visible at point of diagnosis.
Simplifying both new and retrofit installations on boilers and unvented water heaters and cylinders.  RA Tech’s latest innovation, hotun detect – the world’s first in-tundish water detection and temperature sensing, clip on, battery operated PRV discharge warning alarm system, winner of the HVR Awards 2020 for Ancillary Product of the Year.
Professional plumber, heating, ventilation and air conditioning design engineer, Russell Armstrong (Mciphe), MD of RA Tech UK Ltd, (the manufacturers of hotun products), invented the hotun range of dry trap tundishes back in 2013 and has fast become the industries go-to option for a relief valve discharge to an internal drain or soil pipe, and more recently (2019) the hotun detect alarm unit!
Tens of thousands of installers and professionals are now fitting the revolutionary range of hotun dry trap tundishes, enabling the installers, to run a heating or hot water system, temperature and/or pressure relief discharge pipe to an internal waste or soil pipe compliantly in a one-product solution, saving the installer many headaches, time and money.  We call this “the hotun revolution”.

hotun is unique, it is the only dry trap tundish on the market that has visible water at the point of diagnosis amongst many unrivalled features and benefits, and with our latest innovation, hotun detect, takes that concept to a newer, higher level!
