Gas Boilers Combi and Heat Only

(2 Items)

Gas boilers are the UK’s most popular choice for heating and hot water: millions of households rely on them to keep their homes warm all year round. 

These boilers heat water that’s stored in a hot water cylinder until you need it. Unlike combi boilers, heat-only boilers require a separate cold water tank (usually located in a loft area), which then feeds water into the hot water cylinder.

The set-up of gas heating boilers makes them particularly suitable for larger homes or properties with multiple bathrooms, where the demand for hot water is greater. They provide a steady water supply to multiple tapes simultaneously and are a reliable choice for big families. 

Gas boilers can also perform better in areas with low water pressure since they’re not completely dependent on mains pressure for hot water. Newer models (like those you can buy online with Beesley & Fildes) are equally eco-conscious as they are efficient. 

Many of our new boilers for sale are classified under the 'A' rating for energy efficiency, meaning they’re over 90% efficient! With our products, more gas is converted into usable heat for your home, reducing waste and lowering costs.

Gas Boiler FAQs 

What type of boiler is cheapest to run?

The most cost-effective boiler to run depends on various factors, including your heating needs and the energy efficiency of your home. 

Generally, modern condensing boilers are considered the cheapest to run. These gas boilers extract heat from the flue gases, maximising efficiency. Combi boilers, which provide hot water on demand, can also be cost-effective as they eliminate the need for a separate water storage tank. 

However, the overall cost-effectiveness depends on factors like installation costs and the fuel type available in your area. It's advisable to consult with us to determine the best gas heating boiler type for your specific requirements.

Does a boiler use gas when heating is off?

No, gas boilers do not consume gas when the heating is turned off. However, if your new gas boiler is equipped with a pilot light, it will use a small amount of gas continuously. 

Modern gas boilers for sale often have electronic ignition systems, eliminating the need for a pilot light and minimising gas usage when the heating is inactive. 

It's recommended to refer to your new gas boiler's manual and, if concerned about gas consumption, consider upgrading to more energy-efficient model. Regular gas boiler maintenance and ensuring proper settings can also contribute to optimised energy use.

How do I know which boiler to buy?

Choosing the right gas boiler involves considering several factors. Assess your heating and hot water needs, considering the size and layout of your home. Combi boilers are ideal for smaller spaces, providing hot water on demand, while system and regular boilers suit larger homes with multiple bathrooms. 

Check the energy efficiency rating of your new gas boiler; an A-rated boiler is more efficient. 

Seek professional advice from us for a thorough home heating assessment, and review customer reviews for insights into performance and reliability. 

Ultimately, selecting a gas heating boiler tailored to your specific requirements ensures optimal efficiency and cost-effectiveness.

Should I replace my 20 year old gas boiler?

Considering replacing a 20-year-old gas boiler depends on factors like efficiency, reliability, and safety. Older boilers are typically less energy-efficient, leading to higher running costs. Modern boilers are designed with improved efficiency, potentially saving on energy bills. 

Safety is paramount; older gas boilers may pose risks due to wear and tear. If your boiler requires frequent repairs, upgrading to a new gas boiler could be cost-effective in the long run. Additionally, new boilers often come with extended warranties. A professional assessment of your boiler's condition, coupled with a cost-benefit analysis, can guide the decision on whether replacing the boiler is a prudent choice.

Which is better: Combi or Condensing boiler?

The comparison between a combi boiler and a condensing boiler involves understanding their distinct functionalities. A condensing boiler refers to a design that extracts heat from flue gases, optimising energy efficiency. 

On the other hand, a combi (or combination) boiler provides heating and hot water on demand, eliminating the need for a separate water tank. The choice depends on your specific needs and the gas boilers for sale; a combi boiler is space-saving and convenient for smaller homes, while a condensing boiler is efficient for larger homes with multiple bathrooms. 

Both types can be highly efficient, and the decision should align with your heating and hot water requirements. 

How much does it cost to run a combi boiler for an hour?

The cost of running a combi boiler for an hour depends on various factors, including the boiler's efficiency, the energy source, and local utility rates. 

As a rough estimate, a medium-sized gas combi boiler might consume around 28-30 kWh per hour. To determine the cost, multiply the boiler's consumption by the cost per kWh in your area. 

For example, if the cost is £0.05 per kWh, running the gas boiler for an hour may cost approximately £1.40-£1.50. It's essential to check your new gas boiler's efficiency rating and consult your utility provider for accurate cost calculations.
