Description:

In today's cast, I complete our introduction to heating systems with a look at central heating. 

Common to all central heating systems are three main components:

1. The fuel

2. The engine or heater

3. The distribution system - pipes, ducts and outlets

There are two main mediums for transfering heat. Air is common with gas-fired heaters and large ducts but is not as effective as water based systems.

Air ducts can lose up to 1 degree per m of duct. 

Heating that is not true central heating includes inslab or undertile electric element heating, heat transfer and ventilation system.
