Types of Boilers

There are various boiler types, depending on what you are after.

Having the correct boiler installed is important as it could lead to you paying much higher rates on your bills than you initially wanted.

Not only this, but it could also lead to delays on your heating on not forging as much heat as you want.

Here are the different types of boilers you can find:

Combi Boilers

A combi boiler is the most popular type of boiler in 2024.

Supplying hot water and central heating directly to you, a combi boiler is an efficient boiler that requires only a small space in your home (no need for an extra water tank!).

Benefits of Combi Boilers

You will be able to experience a mass amount of benefits when you have your combi boiler installed. Here are some to mention:

  • Cheaper – A simpler structure requires fewer parts to replace and repair, saving you £300 a year.
  • Efficiency – Combi boilers have an efficiency rating of 98%. Only when the heating is needed will the combi boiler be in use.
  • Cleaner – The build-up of grime, debris, and sludge is minimal compared to other boiler structures.
  • Safer – As the water in the combi boiler is directly from the mains, it is always drinkable and safe!
  • Quicker – The heated water will be available on-demand; you won’t need to wait for a water tank to warm up.
  • Compact – A smaller structure with fewer parts (no water tank) means this boiler is suitable for homes and smaller spaces.

How Much Does a New Combi Boiler Cost?

When looking at having a combi boiler installed, the price you are looking at will be in the range of £1,500- £3,000.

It is difficult to give a specific price for a combi boiler as many factors will make the price a variable.

Some of the factors that will differ the price consist of:

  • The brand.
  • The type of boiler.
  • The Location.
  • Any additional parts.

Heat Only Boilers

Heat-only boilers are regular boilers that involve a structure of two tanks, a hot water cylinder, and the boiler.

You will often find this specific style of boiler in a larger property to fulfil its usage and deliver hot water across a building for multiple taps.

A heat-only boiler is filled with water from the mains, and the cylinder will heat up to supply you with hot water to deliver to your taps.

Benefits of Heat Only Boilers

Many advantages come along with a heat-only boiler.

Here are a few to mention:

  • Less effect on water pressure.
  • High demand usage (multiple taps at once).
  • Larger- more water can be heated for further usage.

How Much Does a New Heat Only Boiler Cost?

A heat-only boiler is usually between £700- £2,000.

It is difficult to put an exact price on a heat-only boiler as there are limiting factors that should always be discussed.

Some of the variables you should be aware of are:

  • The type of boiler chosen.
  • The location.
  • The brand.

System Boilers

A system boiler is a high-demand heating supply usually installed for a large home or building that uses a stainless steel heat exchanger to transfer energy from gas to water.

System boilers are, unlike combi boilers, not connected to the cold mains. This new boiler only requires a boiler, cylinder, and a pump. (An expansion tank isn’t always necessary).

System boilers are best for a larger space when needing to deliver hot water to multiple taps and showerheads.

Benefits of System Boilers

Benefits are important when choosing your boiler as you want to ensure you get the best out of your heat supply.

We have listed some of the amazing advantages that you can experience with a system boiler below:

  • A large supply of hot water at once.
  • Smaller than a regular boiler.
  • Hot water is always available.
  • Affordable to run.
  • It can be used with solar thermal systems.

How Much Does a New System Boiler Cost?

When installing a system boiler, you will look at the pricing between £500 and £2,000. The more ‘premium’ boilers will be from £1,500 upwards.

To state an exact price for a system boiler would be incredibly difficult as the prices change depending on some limiting factors; here are some to mention:

  • The type/ model.
  • The brand.
  • The location.
  • Added extras.

What is a Boiler Company?

A boiler company will deliver, install, and service a boiler for its customers. Your boiler must be serviced to be certain that your boiler is safe to run whilst being efficient.

The engineers installing your combi, system, or regular boiler should be registered with Gas Safe and should have installed the heating systems within 30 days.

It is important to work with a reputable boiler company as trust is key when working with your boiler. Safe heating is essential as it can be life-threatening as carbon monoxide leakages can occur.

Why Should I Buy a New Boiler?

Replacing your old boiler is always a good idea, especially when changing your old gas model to an energy-efficient boiler.

Not only will you be saving money on heating prices, but you will also be doing your part to reduce environmental harm with detrimental gasses.

Usually, people consider replacing their old model with a new boiler after 10-15 years. After this time scale, an old gas boiler will be less effective with heating, and the efficiency will drop.

Replacing your old boiler with an energy-efficient model is the best idea as you can experience plenty of benefits and look more pleasing to the eye, which is always an advantage!

How to Choose the Best Boiler Manufacturer

When choosing a boiler brand manufacturer, you should be on the lookout for these specific factors:

  • Highly rated customer reviews.
  • Customer service performance strength.
  • High-efficiency ratings.
  • Trustpilot reviews.
  • Awards (Which? Best Buy Awards are great for boiler manufacturers).
  • Years of experience.

What Size Boiler Do I Need?

You should choose your boiler size by the number of radiators you have around the space.

The more radiators you have, the larger the boiler size you should have installed.

When you have under ten radiators in your location, it is recommended for you to have a 24-27 kW boiler. For 10-15 radiators, you should have a 28-34 kW boiler installed, and 15-20 radiators would need a 32-40 kW model.

How Do Boiler Companies Make Money?

Boiler companies make money from the services they provide. Each boiler company differs in service types; however, many companies project the same services (often at differing prices).

The services usually provided by a boiler company would be the installation and the servicing of the boiler.

Boiler Companies to Avoid

Finding the best and most reputable boiler company when installing a new boiler is important.

You should look out for certain traits when considering a boiler company.
