Thermomax - World leading solar vacuum tube collectors

Solar thermal technology transforms direct and diffuse solar radiation into useful heat using a solar collector. Each Thermomax collector consists of a highly insulated water manifold and a row of tubes. The vacuum inside each tube provides perfect insulation and therefore, protects the system from outside influences, such as cold and windy weather or high humidity. This vacuum insulation also ensures that the energy collected from the sun is very efficiently and effectively transferred into usable heat as there is minimal heat loss.

Thermomax are the original and still the best all-round, highest performing vacuum tube collectors in the world

Thermomax vacuum solar tubes are acknowledged as the most efficient method of generating solar hot water whatever the weather - designed specifically for North American climates. In addition to domestic hot water, the superior performance of a Thermomax vacuum tube collector can also provide central heating support for standard, specialized industrial hot water heating for high temperature applications and solar cooling.


  • Provides up to 70% of your annual hot water
  • Vacuum tube technology provides rapid conductivity and transfer of heat, 30% more effective than flat panel collectors.
  • Thermomax products are designed specifically to work in North American climates, even in cold, wet and humid conditions.
  • Works from dawn until dusk and throughout the year.
  • 5 year standard warranty, 20 years if installed by a Kingspan Solar Accredited Installer.
  • Average 25-year lifespan.
  • SRCC approved
  • Certified to withstand hail impact test DIN EN12975-2:2006 using ice-balls.


The HP200 Heat Pipe Collector

This collector is a ‘dry’ heat pipe product. In this collector, the heat pipe is attached to the back of the absorber plate. Evaporator fluid is contained within the heat pipe.

The energy absorbed by the absorber causes the fluid to change from a fluid state to a vapour state and the vapour rises to the condenser bulb.

The condenser is connected directly into the manifold via a dry pocket. Within the manifold the solar system solution is passed across the dry pocket that houses the condenser.

The condenser releases the latent heat of evaporation to the solar system solution and condenses, the condensate returns to the heat pipe and the cycle is repeated.

Due to the dry connection the HP200 tubes can be replaced without the need of draining down the solar system.

HP200 collectors are available in 3 sizes:

10 Tube = 1.08m2 aperture area
20 Tube = 2.16m2 aperture area
30 Tube = 3.24m2 aperture area

Up to a maximum of 4 x 30 tubes collectors can be joined together in series with a flow rate of 12 Ltrs/min.

Features and Benefits:

  • Highly efficient heat transfer
  • Temperature limitation safety feature
  • Dry system for ease of installation and maintenance
  • Most established product in the market
  • 'Plug & play' design
