Heating Systems phase 1.1/2

What was the main reason for the development of fully pumped heating systems in domestic heating systems?

• To increase the use of gravity circulation

• To eliminate gravity circulation

• To reduce the number of motorised valves

• To make the system less efficient

What is considered wasteful in gravity circulation heating systems?

• The use of a circulating pump

• The use of motorised valves

• The use of heat energy and fuel

• The inclusion of a storage cylinder

How is temperature control maintained in the described heating system?

• By using a single thermostat for the entire system

• By using a room thermostat and a separate cylinder thermostat

• By manually adjusting the motorised valves

• By eliminating the use of thermostats altogether

What type of valve does the Honeywell Y Plan use?

• A two-port motorised zone valve

• A three-port motorised mid-position valve

• A three-port motorised diverter valve

• A four-port motorised valve

Which Honeywell plan uses a three-port motorised diverter valve?

• Honeywell Y Plan

• Honeywell W Plan

• Honeywell S Plan

• Honeywell X Plan

How many two-port motorised zone valves are used in the Honeywell S Plan?

• One

• Two

• Three

• Four

What is one of the benefits of fully pumped systems in terms of system design?

• Limited choice of system design

• Reduced choice of boiler position

• Greater choice of system design

• Mandatory positioning of components

With fully pumped systems, why is it no longer necessary to have the cylinder higher than the boiler?

• Because the system requires manual operation

• Because gravity circulation has been eliminated

• Because it is less efficient

• Because it is a requirement by law

What is a benefit of fully pumped systems regarding the heating times of hot water?

• Slower hot water heating times

• Quicker hot water heating times

• No impact on hot water heating times

• Periodic hot water heating times

What is the function of the mid-position valve in the Honeywell 'Y' Plan fully pumped heating system layout?

• To control the flow of water to the central heating circuit only

• To control the flow of water to the hot water circuit only

• To control the flow of water to both the central heating and hot water circuits

• To provide electrical power to the heating system
