What is the main purpose of central heating?

• To provide thermal comfort in one room

• To provide thermal comfort in every room

• To reduce energy consumption

• To cool down the rooms

What is the purpose of background central heating?

• To cool down the rooms

• To take the chill out of the rooms and heat them to a lower temperature

• To heat all rooms to a specific temperature

• To provide selective heating

What type of central heating system allows some rooms in a property to be heated at the same time to a specific temperature set by the customer?

• Full central heating

• Background central heating

• Low pressure, open vented systems

• Selective central heating

What is the main characteristic of most central heating systems?

• They use gas to transport heat

• They use oil to transport heat

• They use water to transport heat

• They use electricity to transport heat

What is the main disadvantage of low pressure, open vented systems?

• They are not compliant with Building Regulations Part L
