Thermomax Solar

Radical Energy install Thermomax evacuated tube solar panels from Kingspan Solar to guarantee exceptional performance of our solar thermal installations. Thermomax have an excellent reputation and are one of the most highly-respected manufacturers within the solar thermal industry. Thermomax products are manufactured in the UK from the highest quality materials and, having been at the forefront of the industry for several decades, means their products have exceptional efficiencies and technological advantages.

The Thermomax range of evacuated tube solar collectors is Solar Keymark approved and not to be confused with cheaper, inferior products from the Far East. These solar panel systems are well-proven with extended lifetimes. The improved visual aesthetics over competitor solar thermal panels means lower roof profiles for a more discreet appearance. Thermomax products are listed on the Microgeneration Certification Scheme (MCS) Product List which means a certified installation from Radical Energy qualifies for the Renewable Heat Incentive (RHI) for a healthy return on your investment. 

The key to the superior performance of Thermomax evacuated tube systems lies in the vacuum integrity of the solar tubes. In the same way a “Thermos” flask uses a vacuum to prevent loss of heat from the hot liquid inside, the evacuated solar tubes trap radiant heat from the sun to generate hot water very efficiently. Without this vacuum seal, valuable heat would be easily lost from the tube and the solar panel would perform inefficiently. Every Thermomax evacuated tube panel has the following benefits:

  • Microgeneration Certification Scheme (MCS) approved product
  • Qualifies for the Government Renewable Heat Incentive (RHI) scheme
  • 30% increased efficiency over flat panels
  • Typically provide up to 70% of annual domestic hot water requirement, depending on system design
  • Provide all year round contribution to hot water regardless of wind, rain and cloud
  • Larger solar panel installations can provide a contribution to central heating
  • Suitable for flat roof installation
  • Temperature-regulating safety technology

The new innovative range of Varisol solar thermal panels from Thermomax represents the new generation in solar thermal technology. The Varisol solar thermal system is a innovative, new modular range giving a “step-wise” transition in both improved design flexibility and further-reduced roof profiles.  

Every Radical Energy approved solar thermal installation is covered by a 10 year manufacturers’ warranty with a minimum anticipated system lifetime of 25 years. Please contact us to discuss your domestic or commercial project and we will be pleased to advise you.
