What does 'zoning' mean in the context of central heating systems?

• Adjusting the temperature of the entire house at once

• Dividing the heating system into areas that require separate time and temperature control

• Turning off the heating system completely

• Combining all heating areas into one control system

According to Building Regulations Approved Document L1A/B, how many independently controlled zones must a central heating system have in a single storey dwelling with a living area greater than 70% of the total floor area?

• 2 heating zones and 2 hot water zones

• 3 heating zones and 1 hot water zone

• 2 heating zones and 1 hot water zone

• 1 heating zone and 1 hot water zone

What are the minimum independently controlled zones required in a central heating system with stored hot water installed?

• 3 heating zones and 1 hot water zone

• 2 heating zones and 2 hot water zones

• 2 heating zones and 1 hot water zone

• 1 heating zone and 1 hot water zone

What is the benefit of installing digital programmable thermostatic radiator valves in rooms with solar gain?

• They reduce the overall temperature of the house

• They are only suitable for north-facing rooms

• They increase energy usage

• They react quickly when the room heats up

How does separate temperature control contribute to a more comfortable living environment?

• It only works in rooms with no solar gain

• It reduces the temperature in all areas of the house

• It allows for different temperatures in different areas of the house

• It maintains the same temperature in all areas of the house

What is the benefit of separate time control in a central heating system?

• It has no impact on energy usage

• It activates all zones at the same time

• It saves energy by activating zones only when occupied

• It increases energy usage by activating all zones at different times

What is the minimum number of heating zones required in a central heating system according to Building Regulations Approved Document L1A/B?

• 3

• 4

• 2

• 1

What is the purpose of zoning in a central heating system?

• To have only one control system for the entire house

• To heat all areas of the house at the same time

• To increase energy usage

• To prevent unnecessary heating of unoccupied spaces

What is the benefit of multi-channel programming in a central heating system?

• It is only suitable for single storey dwellings

• It reduces the overall temperature of the house

• It increases energy usage by activating all zones at different times

• It allows for timed activation of individual rooms or multiple zones set from a single point

What is the purpose of installing every zone with individual time and temperature control in a central heating system?

• To have only one control system for the entire house

• To increase energy usage by activating all zones at different times

• To reduce energy usage by activating zones only when occupied

• To have the same temperature in all areas of the house
