Essential Interview Questions For Oil Boiler
1. What is the purpose of the oil boiler in a central heating system?
The oil boiler is the central component of a central heating system that uses oil as fuel. It is responsible for heating water that is then circulated throughout the system to provide heat to radiators, underfloor heating, or other hot water outlets in the house.
2. Describe the different types of oil boilers?
- Conventional boilers: These boilers heat water in a tank for storage and later use. They are less efficient than other types of boilers and have a limited hot water supply.
- Combi boilers: These boilers heat water on demand, eliminating the need for a storage tank. They provide both heating and hot water and are more energy-efficient than conventional boilers.
- System boilers: These boilers are similar to combi boilers but require a separate hot water storage cylinder. They are more efficient than conventional boilers and can provide a higher hot water flow rate.
3. Explain the combustion process in an oil boiler?
- Air is drawn into the boiler and mixed with oil, creating a fine mist.
- The mist is ignited by an electric spark or flame, initiating combustion.
- The heat generated by combustion heats water passing through a heat exchanger.
- The combustion gases are then expelled through a flue.
4. How do you determine the efficiency of an oil boiler?
The efficiency of an oil boiler is measured by its Annual Fuel Utilization Efficiency (AFUE) rating. A higher AFUE rating indicates a more efficient boiler that wastes less fuel. The AFUE rating is typically between 80% and 95%, meaning that 80-95% of the fuel’s energy is converted into heat for the home.
5. What are the common maintenance tasks for an oil boiler?
- Regular cleaning and inspection
- Flue and chimney inspection
- Oil filter replacement
- Pump and valve maintenance
- Annual servicing by a qualified technician
6. Describe the safety features of an oil boiler
- Flame failure devices to shut off the burner if the flame goes out
- Overheat protection to prevent the boiler from overheating
- Pressure relief valves to release excess pressure
- Spill trays to contain any oil leaks
- Flue gas analyzers to monitor carbon monoxide levels
7. What troubleshooting steps can you take if an oil boiler is not working?
- Check if the boiler is receiving power and fuel
- Reset the boiler
- Check the thermostat and ensure it is set correctly
- Inspect the flue and chimney for blockages
- Contact a qualified technician for further assistance
8. How do you calculate the size of an oil boiler required for a property?
The size of the boiler required depends on factors such as the size of the property, insulation levels, and hot water demand. Generally, a larger property or one with poor insulation will require a larger boiler. A qualified heating engineer can perform a heat loss calculation to determine the appropriate boiler size.
9. What are the advantages of using an oil boiler over other heating systems?
- Fuel efficiency: Oil boilers are highly efficient, converting most of the fuel’s energy into heat.
- Reliability: Oil boilers are generally reliable and have a long lifespan.
- Cost-effectiveness: Oil can be a cost-effective fuel source, especially in areas where gas is not available.
- Ease of installation: Oil boilers can be installed relatively easily, especially if there is an existing oil supply.
10. What are the disadvantages of using an oil boiler over other heating systems?
- Fuel storage: Oil boilers require a storage tank for fuel, which takes up space and needs regular filling.
- Maintenance: Oil boilers require regular maintenance, including cleaning and servicing.
- Environmental impact: Oil is a fossil fuel, and burning it releases greenhouse gasses.
- Cost of fuel: The cost of oil can fluctuate, potentially affecting running costs.
