The following section details the product features and relevant technical data of the
components of the Dimplex solar offering. Where applicable a general description of the
component’s function is given.
4.1 Dimplex solar collector SOLC220
4.1.1 General description
The Dimplex solar collector SOLC220 is a solar thermal flat plate collector. A cross sec-
tional drawing of the Dimplex SOLC220 is given in Figure 8 detailing the individual col-
lector components.
Figure 8 – Flat plate collector components
Due to its construction, a flat plate collector is subject to conduction, convection and
radiation heat losses. The sum of these heat losses and the design and production qual-
ity are summarised in the thermal collector efficiency which is empirically determined
through independent third party testing and expressed in Equation 1. The heat loss
modes of a flat plate collector are shown in Figure 9.
