Part 1 Phase 3 9189 Central Heating Technologies Quiz

What has revolutionized domestic heating ?

• Environmentally friendly technology

• Zero carbon and carbon neutral fuels

• The re-emergence of underfloor heating

• The advent of heat pumps and solar systems

What is one of the benefits of new central heating technologies ?

• Increased reliance on carbon-rich fuels

• Higher installation costs

• Lower carbon footprint of domestic properties

• Limited availability to select few

What is the main requirement of Approved Document L for central heating systems?

• Installation of solar panels

• Use of energy-efficient light bulbs

• A boiler interlock

• Installation of double-glazed windows

According to the Building Regulations, how many heating zones must a home be divided into?

• At least one

• At least two

• At least three

• At least four

What is the purpose of a boiler interlock in a central heating system?

• To increase water pressure

• To prevent the boiler from cycling when there is no demand for heat

• To reduce noise levels

• To enhance air circulation

What must be controlled by a thermostat in living and sleeping areas according to Approved Document L?

• Humidity levels

• Air quality

• Temperature

• Lighting

What is the minimum standard for boiler interlock in gas-fired wet central heating systems?

• The boiler and pump should remain on at all times.

• System controls should be wired so that when there is no demand for space heating or hot water, the boiler and pump are switched off.

• The boiler should be manually turned off when not in use.

• The pump should operate independently of the boiler.

For dwellings with a total floor area greater than 150 m², what is the zoning requirement?

• One space heating zone is sufficient.

• No zoning is required.

• At least two space heating zones, each with an independently controlled heating circuit.

• Zoning is optional.

What is a recommended good practice when replacing components of gas-fired wet central heating systems?

• Use manual controls for all systems.

• Upgrade gravity-fed systems to fully pumped.

• Avoid using any interlock systems.

• Use a single time control for all heating needs.

What is the minimum standard for hot water cylinders in terms of energy loss?

• Energy losses should not exceed Q = 1.28 x (V^2) kWh/day.

• Energy losses should not exceed Q = 1.28 x (0.2 + 0.0521V^2/3) kWh/day.

• Energy losses should not exceed Q = 1.28 x (0.5 + 0.0521V^2/3) kWh/day.

• Energy losses should not exceed Q = 1.28 x (0.1 + 0.0521V^2/3) kWh/day.
