Characteristics

Save up to 10% on your energy bills!

Unique to the Henrad ECO radiator is the concept whereby hot water flows directly into the front element first, giving it a higher temperature. This delivers more radiant heat, enhancing your feeling of comfort. As a result of the increased radiant temperature at the front of the radiator, the rear-most element is a little less warm than with other radiators.

This means there is less radiant heat lost through the wall via the back of the radiator. Altogether, this means an increase in your feeling of comfort, a reduction in your energy bills, an increase in the efficiency of your heating systems and a reduction in CO2 emissions.

Why opt for a Henrad Premium ECO radiator?

  • UP TO 10.5% reduction in your energy bills
  • UP TO 50% more radiant heat
  • UP TO 53 % higher average surface temperature in the front element
  • Retention of that feeling of comfort with lower temperature systems
  • UP TO 23% faster to heat up
  • UP TO 8.8% reduction in energy loss as the result of less heat radiated from the rear-most element
  • UP TO 6% saved by pre-set thermostatic valve
  • Suitable for renewable energy
  • Environmentally friendly heating
  • Valve that can be fitted on the left or right

Technical details

Technical details

Low-temperature panel radiator made from cold-rolled quality steel, with serial panel water flow (water flows first through the front panel). This results in high energy efficiency, maximum radiation (even in low-temperature installations), fast heating-up process and less energy loss on the wall side.


  • Product:
the Henrad low-temperature valve radiator with serial flow technology, both a centre and lateral bottom connection and a pre-set valve insert, which can be fitted on the left or right side of the radiator
  • Finishing:
upper grille and side panels
  • Pre-installed:
pre-set Heimeier 4368 or 4369 valve, ECO air vent and blind plugs
  • Valve insert:
The integrated adjustable valve insert (without thermostatic head) is factory-fit on the right side of the radiator, CEN certified, tested in accordance with EN215 and compatible with thermostatic heads M30 x 1,5mm. For types 21 – 22 – 33 the valve insert can also be fitted on the left side of the radiator, a left version for a type 11 radiator is available on request.
The thermostatic valve insert is factory-set in relation to the size of the radiator. This pre-setting ensures optimum throughput in the radiator. Factory setting for two-pipe systems, also suitable for one-pipe systems (as long as the valve insert is adjusted to position 8).
  • Also supplied:
VDI brackets (type Monclac), screws, plugs and installation instructions
  • Connections:
2 x ¾” male Euroconus centre connection, 2 x ½” female lateral bottom connection
