Benefits

Save on your energy bills! Even in places with a higher humidity level like bathrooms.

Unique to the Stelrad 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 Stelrad ECO Galva radiator?

  • Protective galvanised coating
  • Reduces your energy bills
  • More radiant heat

Technical details

Technical details

The ECO radiator and its serial flow technology are perfectly suited to operate in low-temperature heating systems. This technology (water flows first through the front panel) results in higher energy efficiency, maximum radiation, faster heating rate and less waste of energy through the back wall. In addition, the ECO Galva radiator is treated with a protective galvanized coating, so it can be used without any concerns in wet areas.


  • Product:
low-temperature valve radiator with serial flow technology, perfectly suited for low-temperature heating systems and equipped with a protective galvanised coating underneath, both a centre and lateral bottom connection and a preset valve insert, which can be fitted on the left or right side of the radiator
  • Finishing:
protective galvanised coating without top grille or side panels
  • Pre-installed:
preset Heimeier 4368 or 4369 valve insert, 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 1,5 mm. For types 21, 22 and 33 the valve insert can also be fitted on the left side of the radiator.
The thermostatic valve insert is factory-set in relation to the size of the radiator.
This presetting 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 assembly instructions
  • Connections:
2 x ¾” male Eurocone centre connection and 2 x ½” female lateral bottom connection
  • Lugs:
2 pairs of mounting lugs up to 1.600 mm and 3 pairs from 1.800 mm
