Central heating provides heat only when the customer can afford it

An open fire is used to cool down a room while central heating heats it up

Central heating is less efficient than an open fire

When is thermal comfort attained according to the text?

When the desired heat balance between the body and surroundings is met within the customer's economic constraints

When the heating system is turned off

When the heat balance is too high for the body to handle

When the property is heated by an open fire

Which of the following is NOT a method of heating the home mentioned in the material?

Wet central heating (hydronic heating)

Is the warm air heating system shown in the learning material commonly used in the UK?

What does full central heating allow in a property?

Heating all rooms to a specific temperature set by the customer at the same time

Heating only selected rooms to a specific temperature

Heating all rooms to different temperatures at different times

Cooling all rooms to a specific temperature set by the customer

What must the comfort temperature reach with selective central heating even when the outside temperature is -1°C?

It must reach the temperature set by the customer

It must reach a standard temperature set by the manufacturer

It must reach a temperature higher than the outside temperature

It must reach a temperature lower than the outside temperature

What is the main reason for installing background central heating instead of full or selective heating systems?

To install the system mainly on a cost basis

To provide a higher temperature in all rooms

To achieve the customer's desired comfort temperature at any outside temperature

To use a larger boiler for heating efficiency

What is the purpose of using a smaller boiler or heat emitters in background central heating?

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

To heat the rooms to a higher temperature

To ensure the system achieves the customer's desired comfort temperature

To increase the cost of the heating system

Under what condition would a heating system be classified as background heating?

When it cannot achieve the customer's desired comfort temperature and the outside temperature is −1°C

When it can achieve the customer's desired comfort temperature at any outside temperature

When it uses a larger boiler than usual

When the outside temperature is exactly 0°C

What is now preferred to an open fire for heating and why?

Central heating, because it heats up the whole property

Central heating, because it is cheaper

Electric heating, because it is more modern

Gas heating, because it is more efficient

What has central heating development over the years seen a change from and to?

From solid fuel to gas, oil, and electricity

From electricity to solid fuel, gas, and oil

From gas to solid fuel, oil, and electricity

From oil to solid fuel, gas, and electricity

Why might running costs be a consideration for customers when choosing a system?

Availability of modern technologies

What is a disadvantage of a low-efficiency system?

It can be harmful to the environment and expensive

It has faster heat recovery times

What aspect of performance might be important for a proposed system?

Heat recovery times and hot water generation

The color and design of the system

The complexity of the installation process

What might intimidate a client about the controls of a system?

The complexity of system operation and control

The aesthetics of the control panel

Modern domestic central heating systems are categorized based on what aspect?

The way the system is filled with water and the pressure it operates at

The size of the building they are installed in

The brand of the heating system

What type of system is fed from a feed-and-expansion cistern located at high level?

Low-pressure, open-vented systems

Which type of modern domestic central heating system incorporates an expansion vessel to manage the expansion of heated water?

Low-pressure, open-vented systems

Which type of heating system uses two two-port motorised valves?

System using two two-port motorised valves

What is a characteristic of sealed (pressurised) systems?

They include a system boiler option

Which system is known for having a two-pipe reversed return?
