What Types of Boilers Can I Choose for My Home?

There are three main types of boilers for homeowners: combi, system, and conventional. Each type is suited to different household sizes and hot water demands.

Combi Boilers

Combi or combination boilers provide central heating and hot water directly from the boiler without needing a separate hot water cylinder.

Combi boilers are compact and ideal for smaller homes or flats with limited space. They are highly efficient but may need help to meet the high demand for hot water in larger households.

System Boilers

System boilers require a hot water cylinder but do not need a cold water storage tank. This boiler type suits homes with multiple bathrooms or moderate to high hot water demand.

System boilers provide a consistent hot water supply and are more efficient than conventional boilers, though they require additional storage space for the cylinder.

Conventional Boilers

Conventional boilers, also known as heat-only or regular boilers, use both a cold water tank (usually in the loft) and a hot water cylinder.

These boilers are best suited for larger homes or properties with older radiator systems that may not be compatible with modern combi or system boilers.

Conventional boilers are ideal for homes where multiple taps or showers may be used simultaneously, but they take up more space due to the extra components required.

What Are the Benefits of Upgrading to a New Boiler?

Upgrading to a new boiler offers several key benefits:

Energy efficiency: New boilers operate at 90-94%, reducing energy consumption and lowering gas or electricity bills.
Reduced carbon footprint: More efficient boilers produce fewer carbon emissions, making them more environmentally friendly.
Increased reliability: Modern boilers are less prone to breakdowns and require fewer repairs, reducing maintenance costs.
Improved home comfort:
A new boiler provides more consistent heating and hot water, improving home comfort.
Property value: Upgrading to a modern heating system can increase the resale value of your home and appeal to potential buyers.

How do I know which boiler suits my home’s heating needs?

To determine which boiler suits your home’s heating needs, consider several key factors, such as property size, hot water demand, energy efficiency, and fuel type.

Property Size

The size of your home plays a significant role in choosing the right boiler. A combi boiler is usually sufficient for small to medium-sized homes because it provides heating and hot water on demand without needing a separate storage tank.

A system or conventional boiler may be more appropriate in larger homes with more rooms and multiple bathrooms, as these boilers can handle higher hot water demand and provide consistent heating throughout larger spaces.

Hot Water Demand

A system or conventional boiler is likely the best option if your household uses multiple taps or showers simultaneously.

These boilers store hot water in a cylinder, ensuring a reliable supply to meet higher demand. In contrast, a combi boiler is more suited for homes with lower hot water usage since it heats water directly from the mains and may struggle to supply hot water to multiple outlets simultaneously.

Energy Efficiency

For maximum energy savings, look for an A-rated boiler with high efficiency, typically between 90% and 94%.

Combi boilers are more efficient for smaller properties since they heat water only when needed. In contrast, systems and conventional boilers may have higher standing heat losses due to the need for hot water storage.

Fuel Type

The availability of fuel in your area can also influence your decision. Gas boilers are the most common and cost-effective in areas with access to the gas grid.

However, if your home is off-grid, you may need to consider an oil, LPG, or electric boiler. Electric boilers are highly efficient but have higher running costs than gas or oil systems.

How long does a boiler installation take?

A boiler installation typically takes between 1 and 3 days. The exact duration depends on the complexity of the installation, the type of boiler being installed, and any additional work required.

Straightforward like-for-like replacements, where the new boiler is installed in the same location as the old one, usually take one day.
Relocating the boiler to a different part of the house or upgrading the heating system, such as replacing pipework or adding radiators, can extend the process to 2 or 3 days.
Additional tasks like power flushing the system or installing a new flue can also add time to the installation.

Before installation, the engineer will assess the scope of work and provide an estimated timeframe based on your home’s specific needs.

Are there any additional costs during or after installation?

Additional costs can occur during or after a boiler installation. These may include system upgrades such as new pipework, radiators, or smart thermostats, which can add to the overall price.

If a power flush is required to clean the system before installing the new boiler, this typically costs between £300 and £500. Relocating the boiler or modifying the flue can also increase costs.

After installation, you’ll need to factor in annual servicing, which generally costs £80 to £120, to maintain the boiler’s warranty and ensure long-term performance.

Can I replace my old boiler with an energy-efficient model?

You can replace your old boiler with an energy-efficient model. Modern A-rated boilers are designed to be highly efficient, operating at 90-94% efficiency, which helps reduce energy consumption and lower utility bills.

Replacing an older boiler, especially if it’s more than 10-15 years old, can improve energy efficiency by up to 30%, significantly cutting heating costs.

Additionally, upgrading to an energy-efficient model may qualify you for government grants or incentives to reduce carbon emissions, making the investment even more cost-effective.

How often should boilers be replaced?

Boilers should be replaced every 10 to 15 years, depending on their efficiency and maintenance history.
Signs that a boiler needs replacing include:

Frequent breakdowns: Replacing the boiler may be more cost-effective if it requires constant repairs.
Rising energy bills: Older boilers become less efficient over time, increasing energy usage and higher bills.
Uneven heating: Inconsistent heating across the home or delays in hot water delivery are signs the boiler needs help.
Strange noises: Banging, whistling, or gurgling sounds often indicate internal component failure, signalling the boiler is nearing the end of its life.

Regular servicing can extend a boiler's lifespan, but once it nears or exceeds 15 years, replacing it with a more efficient model is often more cost-effective.

Will a new boiler lower my energy bills?

A new boiler can significantly lower your energy bills by improving energy efficiency. Modern boilers, especially A-rated models, operate at 90-94% efficiency, meaning they use less fuel to provide the same level of heating compared to older models.

If your current boiler is over 10-15 years old, it may run at less than 70% efficiency, increasing fuel consumption.

Switching to a high-efficiency boiler can reduce energy consumption by up to 30%, leading to noticeable savings on your gas or electricity bills.

How do I maintain my new boiler to ensure long-term performance?

To maintain a new boiler and ensure optimal performance, follow these key steps:

Annual servicing: Have a Gas Safe registered engineer service the boiler annually to check for faults, clean components, and maintain efficiency.
Pressure checks: Regularly check the boiler pressure (1 to 1.5 bar) to ensure proper operation.
Bleed radiators: Bleeding radiators remove trapped air and ensure even heat distribution.
Check for leaks: Inspect the system for any leaks around the boiler, pipework, or radiators and address them immediately.
Monitor thermostat settings: Ensure your thermostat is set at an appropriate level to avoid overworking the boiler.

Do you Offer Financing Options for Boiler Installation?

Financing options for boiler installation allow homeowners to spread the cost over time. Depending on the installer, these options often include 0% interest payment plans, low-interest finance agreements, or buy-now-pay-later schemes.

Most providers offer flexible repayment terms, ranging from 12 months to several years, making it easier to manage the expense of a new boiler.

Eligibility and terms may vary based on the installation company and your credit profile, so it's advisable to inquire about specific financing packages before installation.

What certifications and experience should I look for in a boiler installation company?

When choosing a boiler installation company, ensure they have the following certifications and relevant experience:
