A boiler is one of the most important elements of your home, especially in the colder months. Combi boilers are the most popular choice amongst British homeowners: they provide a fast and efficient supply of instant hot water, taking water directly from the mains and heating it as required, and occupy very little space. They only heat water when a tap is on, thus eliminating the need for a storage tank.

What are the benefits of a small combi boiler?

  • A combi boiler is a device that continuously supplies hot water with exceptional efficiency and great space-saving advantages. For this reason, it’s the country’s favourite heating method, present in 70% of households.
  • Because it’s so compact, it’s especially recommended for small houses.
  • It works as both a space and water heating solution.
  • By installing a combi boiler you will be benefiting from huge savings on your (increasingly higher) bills.

Types of boilers

Gas combi boilers

These systems are the most compact ones because they don’t need a cylinder to store hot water, unlike traditional boilers. Gas combi boilers basically heat water on demand, directly from the mains. For that reason, the hot water flows instantly and you won’t have to wait for it to warm up. Moreover, the thermostat controls avoid temperature fluctuations, so you won’t be surprised by sudden cold water streams while you shower.

Because this system is less complex than traditional boilers, installation is fast, easy and cheap. Most importantly, this boiler gives you the highest savings on bills and respects the environment by being the most energy-efficient on the market. The initial investment might be high, but the great savings will help you pay back the installation cost in a short time.

The only thing you should keep in mind before making the investment is that s gas combi boiler may not be the right choice for you if you have a large number of showers and taps running at the same time, because the pressure for each will be significantly lower.

Heat-only boilers

A heat-only boiler is the best choice for large households where multiple taps need to be used simultaneously, such as those with two or more bathrooms. The installation and replacement of heat-only combi boilers is made easier by the fact that they integrate perfectly with previous central heating systems.

Unlike gas combi boilers, they work perfectly even when water pressure is low. However, these systems take up much more space, because they need storage cylinders for the water they use. Moreover, the cylinders can only store a limited amount of water and it isn’t heated straight away, so it takes longer to heat if more people are using it. Insulation must also be considered to avoid heat loss from the water tanks.

Combi boiler installation cost

The installation of combi boilers is quite easy, since they incorporate all the functions of traditional boilers in one compact device. However, installation is not cheap. They are complex systems and the installation may require the removal of old water tanks. If your are replacing a traditional boiler, the installation may require a few days, if not it’s not going to be longer than 2 hours.

This doesn’t mean that you should only consider them for new buildings. In fact, after going through these few adjustments, maintaining and replacing your combi boiler will be fast and easy. Moreover, you will be saving a lot in the long term, which will more than make up for the initial costs. The lower the efficiency of your old boiler, the shorter the payback period will be, starting from approximately 7 years. You will be saving up to £240 annually on gas bills. Adding a combi boiler may also add value to your home.

You can shorten the payback by taking some energy-saving steps. For instance, you should insulate your walls, windows and loft. Your boiler should be serviced regularly to make sure it’s running at full capacity.

When is the best time to invest in a combi boiler?

  • When repairing your existing boiler is not economically worth it anymore, replacing it is the best choice.
  • If your old boiler does not turn off once the desired temperature has been reached: this feature (called “dry cycle”) wastes a lot of energy.
  • If you can’t control the temperature as you wish, e.g. if there’s no thermostat. A new boiler will help you reduce your energy consumption.
  • Old boilers with a visible flame (pilot light) are huge gas wasters.
  • If you’re building a new house, renovating or selling your home.
