Outstanding Heat Dispersion & Coverage
Sierra Radiant Cone Patio Heaters in multiple installations provide gentle warmth
over an area of up to six metres diameter (dependant on ambient weather conditions).
This is sufficient to accommodate four to five tables in the eating area of a
typical
installation.
The number of heaters required and their mounting height may be determined from
the chart below.
