Are you thinking of upgrading your old, dusty boiler to a more modern and super-efficient one? If so, you might want to consider switching to a new, compact combi boiler system if you’re still running a system with a separate hot water tank or cylinder or simply need to replace your old combi boiler.

Let’s break down the advantages and disadvantages of combis, and how you can switch your existing boiler system to a shiny, new combi system.

What are the advantages of combi boilers?

Combi boilers have many benefits over conventional or system boilers, such as:

  • Energy efficiency: Combi boilers are highly efficient, as they only heat water when you need it. This means that they waste less energy and reduce your carbon footprint. According to the Energy Saving Trust, replacing an old gas boiler with an A-rated condensing combi boiler can save you up to £300 a year on your energy bills.
  • Space saving: Combi boilers are compact and do not require a separate hot water tank or cylinder. This frees up valuable space in your home, especially if you have a small property or a loft conversion. You can also install a combi boiler anywhere in your home, as long as there is access to the gas supply and the water mains.
  • Hot water on demand: Combi boilers provide instant hot water at the turn of a tap, without waiting for the tank or cylinder to heat up. This means that you can enjoy a hot shower or bath anytime you want, without running out of hot water or having to schedule your usage.
  • Lower installation costs: Combi boilers are easier and cheaper to install than conventional or system boilers, as they require less pipework and components. You also don’t need to pay for the installation of a hot water tank or cylinder, which can be expensive and time-consuming. This can lower your new boiler cost significantly.
  • Safety: Combi boilers are safer than conventional or system boilers, as they do not store hot water in a tank or cylinder that can leak and lose efficiency over time. They also eliminate the risk of legionella bacteria, which can grow in stagnant water and cause serious health problems.

What are the disadvantages of combi boilers?

Combi boilers are not suitable for every home or situation, as they also have some drawbacks, such as:

  • Water pressure issues: Combi boilers rely on the water pressure from the mains supply, which can vary depending on the demand and location. If you have low water pressure in your area, or if you use multiple taps or showers at the same time, you may experience reduced water flow or temperature fluctuations. You may need to install a pump or a booster to improve the water pressure, which can add to the cost and complexity of the installation.
  • Boiler breakdowns: Combi boilers can be more prone to breakdowns than conventional or system boilers, as they have more moving parts and components. But this can be mitigated if you keep up with annual boiler servicing. If your combi boiler breaks down, you will lose both heating and hot water until it is fixed.
  • Limited hot water output: Combi boilers can only produce a certain amount of hot water at a time, depending on their size and power. If you have a large household or high hot water demand, you may find that a combi boiler cannot cope with your needs. You may need to choose a larger or more powerful combi boiler, which can be more expensive and take up more space.


How much does a new combi boiler cost?

The cost of a new combi boiler can vary depending on a couple of key factors, such as:

  • The type of boiler: The type of boiler you choose can affect its price, as different types have different features and specifications. For example, gas combi boilers tend to be cheaper than oil or electric combi boilers.
  • The size of the boiler: The size of the boiler you choose can affect its price, as bigger boilers tend to be more expensive than smaller ones. However, choosing an oversized or undersized boiler can also cost you more in the long run, as it can waste energy and money or reduce your efficiency and performance. You should choose a boiler that is suitable for your home size and heating and hot water needs.
  • The average new gas boiler cost (without installation) in the UK ranges from £600 to £900, while a mid-range model falls between £900 and £1,200. If you’re looking for a premium combi boiler, prices can vary from £1,000 to £2,000, depending on the boiler’s size. On the other hand, a budget model of a new system boiler is priced at £600 to £900. For a mid-range system boiler, the cost is between £900 and £1,300, and a premium model can range from £1,300 to £2,500. The pricing is influenced by the size and specifications of the boiler.
