DESIGN TO INSTALLATION
Our radiators are specifically designed to minimise any
movement, providing a tight, professional fit that will remain
in place, even after storage, transit and installation. Convectors

APPLICATIONS
Stelrad radiators are suitable for two pipe installations.
For single pipe applications, it is advisable to use diversion tees in
the pipework, as this will assist in obtaining design performance
from the radiators. Although our radiators are suitable for
Microbore pipework, the back tappings make
them unsuitable for twin entry valves.
Stelrad radiators are manufactured under ISO 9001 quality

TEMPERATURE TABLE
For systems not operating at ∆t50 the factors in the table
below should be applied. The output of a given radiator can
be obtained by multiplying the quoted ∆t50 output by the
operating factor. Conversely, to derive a non ∆t50 output,
divide the heat output required by the relevant operation
factor. This ‘∆t50 equivalent output’ can then be used to
select a radiator from the standard tables.

minimising expansion and contraction noise.
The neat nickel-plated plug and vent provide a watertight
joint, whilst complementing the superior finish.
To facilitate easy one off replacement, nickel-plated brass
extension pieces are also available, complete with sealing washer,
in 20mm, 30mm and 40mm options. Recommended height
from the floor to the base of the radiator is 150mm minimum.
This allows adequate airflow when the radiator is placed on the
bracket.
CAUTION
When designing for domestic systems we recommend that the
Stelrad radiators are only used in heating systems complying
with British Standard Code of Practice for Central Heating for
Domestic Premises BS EN 12828:2012 and BS EN12831-1:2017.
