Frequently Asked Questions About Boiler Installation
Planning a new boiler installation? Find answers to common questions about boiler installation, costs, and finding qualified installers.
What type of boiler is best?
The best type of boiler for your home or business depends on several things, including your available space, fuel preferences, and budget. Here are some of the most common types of boilers:
Combi boilers: Combination boilers provide both heating and hot water instantly, saving valuable space. They are compact, efficient, and well-suited for smaller homes or apartments.
Condensing boilers: Condensing boilers are one of the most efficient types of boiler. They extract more heat from the fuel by condensing the water vapor in the exhaust gases, thus saving energy. Because of increased efficiency, condensing units can help lower your carbon footprint and reduce heating costs.
System boilers: System boilers are designed for larger homes and store hot water separately. They are a good option for properties with multiple bathrooms or high hot water demands.
Regular boilers: Regular boilers, also known as conventional or traditional boilers, are the most traditional type of boiler, and they generally require the most space. They are a reliable option for continuous hot water throughout a home.
Consult with a qualified heating engineer to discuss which boiler type is most appropriate for your specific requirements.
How do I bleed my radiators?
If your radiators have cold spots or are not heating up efficiently, they may need to be bled to remove trapped air. This straightforward process can help improve your heating:1. Turn off your central heating system and wait for radiators to cool.2. Locate the bleed valve on the radiator. It's usually a small, square-shaped valve on one of the top corners. .3. Place a radiator key if you don't have a radiator key on the bleed valve and carefully turn. You should hear a hissing sound as air escapes..4. Hold a cloth or container under the valve to catch any water that may drip.5. Continue turning the key until water begins to flow steadily.6. Tighten the valve securely.7. Repeat this process for all the radiators in your home.8. Once you have bled all the radiators, turn your central heating system on and monitor boiler pressure. Confirm that your system pressure is in the normal range for optimal boiler performance. If not, consult with a professional HVAC technician. Adjust the pressure if needed. If unsure, contact a qualified engineer. By bleeding radiators, you can improve their effectiveness and the overall performance of your central heating system.
What is a boiler’s AFUE rating?
The AFUE rating measures a boiler's overall energy efficiency. It's expressed as a percentage. For example, an AFUE of 90% means that 90% of the fuel energy is converted into heat for your home, with only 10% wasted. . The minimum AFUE for new boilers is typically 80%, but higher-efficiency models are available with AFUE ratings exceeding 95%. Prioritize energy efficiency when choosing a boiler to reduce costs and your carbon footprint.
What is a condensing boiler?
A condensing boiler is a very efficient boiler. They recapture and reuse exhaust heat. Condensing boilers increase efficiency and lower heating costs. They're better for the environment as well.
What type of boiler is best?
The best type of boiler for your home or business depends on several things, including your available space, fuel preferences, and budget.Common boiler types include: :
Combi boilers: Combination boilers provide both heating and hot water instantly, eliminating the need for a separate water tank. . They are compact, efficient, and well-suited for smaller homes or apartments.
Condensing boilers: Condensing boilers are highly efficient . They recycle heat from waste gases, improving energy efficiency. Because of increased efficiency, condensing units can help lower your carbon footprint and reduce heating costs.

How do I bleed my radiators?
If your radiators have cold spots or are not heating up efficiently, they may need to be bled to remove trapped air. Here's how to bleed your radiators: :1. Turn off your central heating system and allow the radiators to cool down completely. 2. Locate the bleed valve on the radiator. A special key is often needed.3. Place a radiator key or a flat-head screwdriver on the bleed valve and slowly turn it counterclockwise. . You should hear a hissing sound as air escapes..4. Hold a cloth or container under the valve to catch any fluid that may drip.5. Continue turning the key until the hissing stops and water starts to come out steadily. .6. Tighten the valve clockwise .7. Repeat this process for all the radiators in your home.8. Once you have bled all the radiators, turn your central heating back on and monitor boiler pressure. Confirm that your system pressure is in the normal range for optimal boiler performance. If not, consult with a professional HVAC technician. If the pressure is too low, you may need to top it up using the filling loop, if your boiler has one. If unsure, contact a qualified engineer. By bleeding radiators, you can improve their effectiveness and the overall performance of your central heating system.
What is a boiler’s AFUE rating?
The AFUE rating measures how efficiently a boiler converts fuel to heat over a year. It's expressed as a percentage. For example, higher AFUE ratings indicate higher efficiency, resulting in less wasted fuel and money. The higher the AFUE, the more efficient the boiler and the less fuel you'll need to heat your home, resulting in cost savings.. Look for a high AFUE rating when shopping for a new boiler.
What is a condensing boiler?
A condensing boiler is a very efficient boiler. They recapture and reuse exhaust heat. Condensing boilers increase efficiency and lower heating costs. They're better for the environment as well.
