Types of Boilers We Install

Choosing the right boiler for your home

Combi Boilers

Best for: Small to medium homes with 1-2 bathrooms

Combi boilers heat water directly from the mains when you turn on a tap, eliminating the need for a hot water cylinder or cold water tank. They're space-saving, energy-efficient, and provide instant hot water.

Instant hot water on demand
No water tanks needed
Lower installation costs
Ideal for smaller properties

System Boilers

Best for: Medium to large homes with 2-3 bathrooms

System boilers work with a cylinder to store hot water, making them perfect for homes with high hot water demand. They can supply hot water to multiple taps simultaneously without loss of pressure.

Multiple taps at once
Constant hot water supply
Compatible with solar panels
More efficient than regular boilers

Regular Boilers

Best for: Large homes, traditional systems, or low mains pressure

Also known as conventional or heat-only boilers, regular boilers work with both a cylinder and a cold water tank. They're ideal for properties with existing traditional heating systems.

Works with existing systems
Good for low water pressure
Simultaneous hot water supply
Suitable for large properties

Boiler Installation FAQs

How long does a boiler installation take? ▼

Most boiler installations are completed within 1-2 days. A straightforward combi boiler replacement (like-for-like) typically takes one day. More complex installations, such as converting from a regular boiler to a combi, or significant system modifications, may take 2-3 days.

Do I need to replace my entire heating system? ▼

Not necessarily. If your radiators and pipework are in good condition, we can often connect a new boiler to your existing system. However, we'll assess everything during our survey and recommend any upgrades needed for optimal performance and efficiency.

What size boiler do I need for my home? ▼

Boiler size depends on several factors including the number of radiators, bathrooms, property size, and hot water demand. As a rough guide: 1-2 bed properties typically need 24-28kW, 3-4 beds need 28-35kW, and 5+ beds need 35-42kW. We'll calculate the exact size needed during our survey.

Can I get finance for a new boiler? ▼

Yes, we offer flexible finance options to spread the cost of your new boiler installation. Contact us to discuss available payment plans and find a solution that works for your budget.

What warranty do I get with a new boiler? ▼

Standard manufacturer warranties range from 2-5 years, but as approved installers, we can often provide extended warranties of up to 10 years on select models. We'll also provide our own guarantee on the installation workmanship.

Will a new boiler save me money? ▼

Yes! Modern A-rated boilers are far more efficient than older models. Replacing a boiler over 10 years old could save you 20-30% on your energy bills. A typical household could save £300-£400 per year, meaning the boiler pays for itself over time.
