A new boiler is a significant investment, so choosing the right one for your home is essential. But with so many choices, not to mention which fuel type you should go for, it can seem like a nightmare choice to make.

In this article, we’ll help you to understand the things you need to consider so that you can make the right choice.

Signs That You Need A New Boiler

If your boiler is over 12 years old, it may be time for a new one. Here are some other signs that you need to replace your boiler:

  1. Your boiler used to be more efficient.
  2. You have to constantly repair your boiler.
  3. Your heating bills have gone up.
  4. Your boiler doesn’t heat your home evenly.
  5. You hear strange noises coming from your boiler.

If your radiators are leaking, then it might mean that it’s that part of your heating system that needs replacing rather than the boiler. There is now a vast selection of radiators available, and we’ve found that sites such as Radiator Outlet offer excellent service at very competitive pricing. 

If you’re unsure whether or not you need a new boiler, it’s always best to consult a professional. They can help you assess your situation and make the best decision for your home.

Boiler Fuel Types

Depending on where you live, you may have a choice of the type of fuel that will fire your boiler. The three most common types of boilers are electric, gas, and oil.

  • Electric boilers are the most efficient type, but they require a lot of upfront investment.
  • Gas boilers are less expensive to operate than electric boilers, but they produce emissions that can be harmful to the environment.
  • Oil boilers are the least efficient type, but they are often the most affordable option.

The Different Types Of Boilers

Three main types of boilers are available on the market: combination,  system, and conventional. Each boiler type has its own pros and cons that you should consider before making a purchase.

Combination Boilers

Combination boilers are the most popular type in the UK. They are compact and easy to install, and they provide both heating and hot water on demand. The only downside to combination boilers is that they can’t provide hot water at more than one tap at a time.

System Boilers

System boilers are similar to combination boilers, but they have a few extra features that make them ideal for larger homes. System boilers come with a built-in cylinder that stores hot water, so you can immediately get hot water on demand.

Conventional Boilers

Conventional boilers are the largest type of boiler, and they are typically used in homes with two or more bathrooms. Conventional boilers need to be installed by a professional, and they require a separate hot water cylinder. However, they are the most powerful type of boiler and can provide hot water for multiple taps at the same time.

How To Decide Which Is The Best Boiler For Your Needs

When it comes to choosing a boiler, there are a few things you need to take into account in order to make sure you’re getting the best one for your needs.

Size Of Your Home

First, think about the size of your home – you’ll need a boiler that’s big enough to heat all the rooms adequately.

Hot Water Requirements

Second, consider how much hot water you’ll need on a daily basis – if you have a large family or often entertain guests, you’ll need a boiler that can produce plenty of hot water quickly.


Finally, factor in your budget – boilers can vary widely in price, so it’s important to find one that’s affordable for you. Once you’ve considered all of these factors, you’ll be well on your way to finding the best boiler for your needs.

The Installation Process For A New Boiler

Once you’ve chosen the perfect boiler for your home, the next step is to have it installed by a qualified technician. The installation process can vary depending on the type of boiler you’ve chosen, but all boilers must be properly vented in order to work correctly. This means that a hole will need to be drilled in an exterior wall so that the flue pipe from the boiler can be properly vented.

Gas Boiler Installation

If you’ve chosen a gas boiler, the technician will also need to run a gas line to the boiler. This is usually done by tapping into an existing gas line, but in some cases, a new gas line will need to be run. Oil boilers require an oil line, which is usually installed by running a new line from an exterior oil tank.

Electric Boiler Installation

The installation process for an electric boiler is generally much simpler, as they do not require any venting or gas lines. However, it is still important to have the work done by a qualified technician to ensure that the boiler is installed correctly and safely.

After the installation is complete, the technician will test the boiler to ensure that it is working properly. Once everything has been checked and verified, you’ll be able to enjoy the warmth and comfort of your new boiler.


When it comes time to replace your boiler, be sure to consider all of the factors we’ve mentioned. Doing your research and taking the time to find the best boiler for your home will save you money in the long run by ensuring that your heating system is energy efficient and meets all of your needs.
