Every homeowner will eventually find themselves wondering, “What type of boiler is best for my needs?”
Choosing the right boiler is essential not only for comfort but also for energy efficiency and cost savings. This decision affects your home’s heating efficiency, and knowing what works best for your property can help save you money now and in the future.
If your boiler has recently broken, deciding on the perfect replacement can ensure your home stays warm and comfortable without any hassle.
What needs to be considered before buying a new boiler?
Several factor play a key role in determining which type of boiler is right for your home. One of the most important considerations is the amount of available space. Larger systems, such as traditional regular boilers, require more space, while more compact options, like combi boilers, are ideal for homes with limited room.
If space is a concern, you may want to consider a combi boiler like the Vitodens 050-W or a storage combi like the Vitodens 111-W, or even a system boiler. These options are designed to fit into smaller spaces while still delivering reliable performance.
Water pressure and hot water demand are also crucial factors to consider. If your home has multiple bathrooms or a high demand for hot water, you may need a system that can handle simultaneous use across multiple outlets without a drop in pressure. Choosing the right boiler type is vital to ensure your home’s heating and hot water needs are met efficiently.
In this guide, we’ll cover all the different types of boilers available, how they work, and which one might be best suited for your needs. We’re here to answer the question: “What type of boiler do I need?” and help you make an informed decision based on your specific requirements.
What types of boiler are there?
Let’s explore the most popular types of boilers available in the UK, starting with the most traditional option.
Open Vent Boiler (Regular Boilers)
An Open Vent Boiler, also known as a regular boiler or conventional boiler, is often used to replace older systems. It includes an open vent with a cold-water storage tank and an expansion tack, typically located in the attic. There is also a hot water cylinder that stores heated water.
This setup allows the hot water to be easily distributed to taps or showers throughout the house, making it a good choice for properties with multiple bathrooms or high-water demand.

An open vent could be the right fit for your home if:
- Your current system is already an open vent boiler, and you want to avoid the cost of converting to another type.
- The pipework in your home is too old or fragile to handle the pressure required by combi or system boilers. It may need a power flush to clear out any sludge build-up.
- Your experience low water pressure, particularly in homes with multiple bathrooms or high-water usage.
Combi Boiler
Combi boilers are the most popular choice in the UK. They provide hot water on demand, meaning water is only heated when you need it. This efficient approach helps to save both energy and money. Combi boilers are compact, with all their components housed in a single unit. This means that they don’t require a separate storage tank or hot water cylinder, saving space in your home.
Water for combi boilers is drawn directly from the mains. When you turn on a hot water tap, the gas burner ignites, heating the water instantly, without wasting any time or energy.
A combi boiler could be the best option if:
- You want instant hot water on demand without waiting for a hot water tank to warm up.
- You need to save space, as combi boilers are compact and can be installed in smaller areas like kitchen cupboards.
- You’re looking to reduce energy bills, as combi boilers heat water only when required, minimising waste.
- You have good water pressure in your home, allowing the combi to supply multiple outlets simultaneously.
Popular combi boilers include the Viessmann Vitodens 100-W and 050-W. They are often the best choice for properties, with many being recipients of the ‘Which? Best Buy‘ award.
System Boilers
A system boiler is a great option for homes with higher water demand. Like a combi boiler, it draws water from the mains, but it also needs a hot water cylinder to store the heated water. This setup allows system boilers to supply hot water to multiple outlets simultaneously without loosing water pressure.
System boilers are often considered the “middle ground” between combi boilers and open vent boilers. They offer the convenience of mains pressure hot water, but with a storage cylinder for higher capacity.
A system boiler might be the best choice if:
- You have multiple bathrooms or a high demand for hot water at the same time.
- You want a system that doesn’t require a cold-water storage tank, saving space.
- You prefer faster installation and lower costs than a traditional open vent boiler.
- You prefer faster installation and lower costs than a traditional open vent boiler.
What to Consider Before Buying a Boiler
When selecting a boiler for your home, several important factors should guide your decision:
- Space availability: Is your home suitable for a large system like an open vent boiler, or do you need something more compact like a combi boiler?
- Current system: Is your existing system an open vent, system, or combi boiler? Sticking with a similar type can often simplify installation and reduce costs.
- Water pressure: Your home’s water pressure will influence the type of boiler you need. Combi boilers are ideal for homes with good water pressure, while system or open vent boilers may be necessary for homes with lower pressure.
Take time to assess your home’s specific needs, including the size of the property, the number of people living there, and your hot water usage.
