Episode 5: Central Heating

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.
