One of the most common questions I get asked is "what's the best form of heating?"
Much to the frustration of most people, I usually answer "it depends…" The best type of heater for you and your home does depend on many factors, however there are some guiding principles that apply to all cases.

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.
