What is the key characteristic of 'Centralised' hot water systems?

• Water is heated to a specific temperature

• Water is heated on demand when hot water outlets are opened

• Water is heated and/or stored centrally in the building

• Water is heated and/or stored locally to one specific draw-off point area

In which hot water system is water heated on demand when hot water outlets are opened?

• Stored

• Centralised

• Instantaneous

• Localised

What is the primary characteristic of 'Localised' hot water systems?

• Water is heated to a specific temperature

• Water is heated and stored centrally in the building

• Water is heated and stored locally to one specific draw-off point area

• A cylinder of water is heated to temperature before distribution

In a centralised - stored hot water system, where is the hot water cylinder typically located in a domestic property?

• Under the sink

• In the kitchen

• Centrally located in an airing cupboard

• In the garden shed

What type of boiler is commonly used in a centralised - instantaneous hot water system for smaller domestic properties?

• Oil-fired boiler

• Combination boiler

• Electric boiler

• Solar-powered boiler

In which type of properties is the centralised open-vented indirect gravity system commonly found?

• Newly constructed homes

• Older properties

• Industrial buildings

• Commercial office spaces

How does heat transfer from the boiler to the cylinder in a centralised open-vented indirect gravity system?

• Through a pump

• By electrical conduction

• Via convection

• Using a heat exchanger

How is heat transferred from the boiler to the cylinder in a centralised open-vented indirect pumped primaries system?

• Through conduction
