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.

Oil Heat Boiler FAQs

The Basics

As someone living in the Greater Boston area, you know how harsh winters can get. You hopefully also realize how hard your boiler works to keep you and your family comfortably warm. And you’ve probably noticed your need for heating oil has increased. Thankfully, you’ve got a dependable heating oil provider. You can always count on Scott Williams for heating oil service, heating oil delivery, and great heating oil pricing. We also provide expert boiler installation, boiler repair, and boiler maintenance in Boston’s South Shore.

You depend on heating oil and on your boiler to keep your household warm, but how much do you know about heating oil and boilers? Keep reading to find out.

What Is Heating Oil?

Heating oil is made from crude oil that has gone through a refining process called distillation. Through the process of distillation, hydrocarbons are removed from the crude oil and become a substance that can be further purified and blended to make the heating oil that works in your home’s furnace or boiler.

However, Scott Williams doesn’t just deliver conventional heating oil. As part of our commitment to fuel efficiency and energy conservation, we deliver B10 Bioheat® fuel, a blend of ultra-low-sulfur heating oil and 10% biofuel that’s made from renewable sources. This is just one of the ways we strive to provide our customers with the best value possible.

Furnace vs Boiler

Some people use the words furnace and boiler interchangeably, but they’re not the same thing. It is true that both appliances heat your home, but each goes about it in a slightly different way.

What is the difference? A boiler heats water while a furnace heats air. A boiler’s circulator pumps the hot water through a system of pipes, distributing the water to radiators, baseboards, or air handlers throughout the home. Some older boilers are designed to create steam. The pipes are connected to steam radiators throughout the home.

The easiest way to tell if a home has a boiler or a furnace is to check for radiators and vents. A home that has radiators (or baseboards) also has a boiler. A home with vents has a furnace.

How Do Boilers Work?

Boilers use hot water or steam to heat your home. For this reason, a boiler is called a hydronic heating system. A boiler can either be a hot water boiler or a steam boiler.

If you have a hot water boiler, your boiler burns fuel to heat water. That hot water is then pumped through pipes to baseboards, radiators, in-floor radiant tubing, or other sealed hydronic devices throughout your South Shore home. Then the water returns to the unit and the cycle repeats.

If you have a steam boiler, the process is very similar to that of a hot water boiler. However, in the case of a steam boiler, the water is converted to steam before being circulated throughout your home.

Boilers run quietly and generate comfortable warmth. They don’t rely on fans or blowers, so they don’t contribute to the blowing of dust, dirt, or allergens in the air.

Is My Boiler Efficient?

How do you determine the efficiency of your boiler? You look for its Annual Fuel Utilization Efficiency (AFUE) rating. The higher the AFUE, the more energy-efficient the unit is.

Here are the ranges:

• 56 – 70 AFUE: low efficiency
• 80 – 85 AFUE: medium efficiency
• 90 – 98.5 AFUE: high-efficiency

According to the US Department of Energy, older furnaces and boilers have efficiencies in the 56% to 70% range. However, modern heating systems can have an AFUE as high as 98.5%.
