Chapter 7 Central heating systems

Fan convectors tend to be larger than traditional radiators and they also require
a mains electric connection, usually via a switched fuse spur. There are two
separate types of fan convector, as follows.
1 Wall mounted: these tend to be quite large in size. The manufacturer’s data
should be consulted to allow the correct heat output to be selected.
2 Kick-space heaters: specifically designed for kitchen use where space to
mount a radiator is limited. They are installed under a kitchen unit and blow
warm air via a grille mounted on the kick plinth.
Tubular towel warmers

These are available in a range of different designs and colours, and are often
referred to as designer towel rails. They can be supplied for use with wet central
heating systems with an electrical element option, for use during the summer
when the heating system is not required. They are usually mounted vertically on
the wall and can be installed in bathrooms and kitchens.

Towel warmers with integral panel radiators
Less popular than tubular towel rails, these heat emitters combine a towel rail
and radiator into one unit. They allow a towel to be warmed without affecting
the convection current from the radiator. They are generally installed only in
bathrooms.
Skirting heating

Skirting heating consists of a finned copper tubular heat exchanger in a
metal casing that replaces the skirting boards in a room. It is usually used
where unobtrusive heat emitters are required. Skirting heating can be used
as perimeter heating below glazing or for background heat in some areas.
