Steel panel radiator Hi-Therm 33HTVK — bottom connection

Hi-Therm 33HTVK is a Type 33 steel panel radiator with bottom connection. Designed for closed water-based heating systems in homes, offices and commercial premises. Choose the height and length to suit the room’s heat loss and the operating temperatures of the heating system.

Hi-Therm 33HTVK

Construction and features

Hi-Therm 33HTVK combines steel heating panels with convector fins to transfer heat from the heating water to the room. The range offers four heights and a choice of lengths, so the radiator can be selected for the required heat output and installation position. The exact product codes, dimensions and output values are listed in the technical information tab.

  • Type: 33
  • Operating pressure: 10 bar
  • Maximum temperature: 95°C

Panel construction

Type 33 has three heating panels and three rows of convector fins. This construction provides the highest heat output of the three types at matching height, length and temperature difference. Compare the output of the exact size when selecting a radiator.

Connection to the heating system

HTVK models have bottom connections for pipework approaching the radiator from below. Select the connection fittings and pipe route for the installation design. The connection type distinguishes HTVK from the corresponding HTK version.

Size and heat-output selection

Available heights are 300, 400, 500 and 600 mm; lengths range from 400 to 2000 mm. The exact combinations vary by type and are listed by product code. Heat output is shown at ΔT = 70°C. Select the radiator using the room’s calculated heat loss and the actual system temperatures; a value at a different temperature difference is not directly interchangeable.

Finish and supplied accessories

The steel panels have a white RAL 9016 powder-coated finish. The radiator is supplied with mounting brackets, an air vent and plugs. Thermostatic control accessories are purchased separately.

Operating conditions

For closed heating systems with a membrane expansion vessel. Maximum operating pressure: 10 bar; test pressure: 13 bar; maximum heating-water temperature: 95°C. Avoid permanently damp rooms and corrosive environments. Installation must follow the product instructions and the heating-system design.

Warranty: 10 years, subject to compliance with the installation and operating conditions.
