Forceflow LST - Low Surface Temperature Fan Convector

Fan convectors are an established and cost-effective way of heating schools, libraries, nurseries and many more. With minimal maintenance requirements, fan convectors rapidly distribute heat across the rooms whilst occupying much less wall space than a radiator of equivalent output.

A heat emitter with a surface temperature no greater than 43°C is considered a major safety benefit and because traditional fan convectors may have a surface temperature in excess of 50°C, Biddle have developed the LST fan convector range.

Thoroughly tested by BSRIA (see report), Forceflow LST is possibly the only fan convector complying with DHSS Engineering Data DN4 and NHS Estates Health Guidance Note ‘ Safe Hot Water and Surface Temperatures’ 1998 (less than 43°C surface temperature with water flow temperatures of 80°C).

  • Features & Benefits

    • Low surface temperature
    • Quick heat up
    • Good heat distribution
    • Much smaller than a LST radiator of equivalent output
    • Simple to install
  • Thermostatic Radiator Valve (TRV)

    A special Thermostatic Radiator Valve (TRV) is fitted to the heating coil pipework and a temperature sensor positioned immediately behind the discharge grille. The valve modulates between the open and closed positions carefully maintaining the discharge air temperature.
