What Type of Boiler Do You Need?

​​Purchasing a new boiler for your property is a significant investment, so you need to make the right choice. Here are the factors to consider when deciding which type of boiler you will need: 

  • The size and layout of your property
  • Your property’s insulation features.
  • Your typical hot water requirements.
  • Your budget.
  • Whether or not your property is connected to the gas grid.
  • Environmental considerations (some boilers have a far greater environmental impact than others).
  • Your water system pressure.

Here are the most popular types of boilers and their suitability for various properties.

Conventional boiler

Conventional boilers, also known as regular boilers, are found in approximately 23 million homes and businesses across the UK. A major reason for their popularity is their ability to keep up with high hot water demands, as several taps and showers can receive hot water at the same time.

Conventional boiler systems are typically made up of a hot water storage tank and a cold water cylinder. These boilers are fuelled by oil, natural gas, or LPG (Liquefied Petroleum Gas). These gases can be dangerous, so expert Gas Safe boiler installation is required for a safe connection to your heating system.

Despite their popularity, conventional boilers are being phased out because of their environmental impact due to high carbon emissions. Climate experts advised that all gas boilers in the UK should be banned by 2033 to reduce the nation’s contribution to climate change. Considering this fact, a conventional boiler may not be the best long-term choice.

Combi boiler

Around 80% of boilers sold in the UK are combi boilers, which can be run on gas or electricity. These boilers combine water heating and central heating in a single unit. Water is drawn from the mains supply so hot water can be provided on demand.

Combi boilers are compact, energy-efficient, and easy to install. The only drawback of this heating solution is that it struggles to provide hot water to multiple taps at the same time. Therefore, combi boilers are a great choice for small office spaces, apartments, and houses with just one bathroom.

Electric boiler

An electric boiler refers to any type of boiler that runs on electricity. There are a few different types available, including electric combi boilers, conventional electric boilers, and electric system boilers. Heating solutions that run on electricity typically have lower installation costs and reduced maintenance needs when compared to gas alternatives.

Electric boilers are a great choice for homes and businesses that do not have a mains gas connection. These boilers also don’t produce any on-site carbon emissions, making them an eco-friendly choice. If you are interested in reducing your environmental impact even further, you could always connect your electric boiler to a solar panel system.

System boiler

If your house or commercial property has more than one bathroom, you may be interested in investing in a system boiler. These boilers have built-in pumps and expansion vessels which save valuable space and make them easy to install and maintain.

One of the main advantages that system boilers offer is that they provide constant hot water to several different taps/showers at the same time. System boilers are also compatible with solar panels and heating controls (which allow you to heat water in advance).

Because system boilers are directly connected to the mains water supply, there is no need for a cold water tank. Although, a hot water tank is necessary for storing hot water. The fuel source for system boilers is typically gas or oil. 

Biomass boiler

Are you looking to reduce your carbon footprint and become more energy efficient? A biomass boiler could be a great choice. Biomass boilers use organic matter, such as wood chips and logs, for fuel. These resources are significantly cheaper than fossil fuels like gas or oil.

The only downside to biomass boilers is their installation cost, which could easily cost you upwards of £10,000! The good news is that the UK Government’s Boiler Upgrade Scheme offers grants of £5,000 to homeowners and businesses looking to invest in a biomass boiler.

How Much Does it Cost to Install a New Boiler in Featherstone?

When it comes to boiler installation, there are a few factors that determine the overall cost These include:

  • The type of boiler you want to have installed.
  • The type of boiler you currently have.
  • Whether or not your pipes require upgrading.
  • The size of your home or commercial building.
  • If you need to relocate your boiler to another room.
  • Whether or not your radiators require upgrading.

Because of the various contributing factors, it’s difficult to provide the exact costs involved. Below are the estimated costs for residential properties and commercial businesses.

  • The type of boiler (combi boilers typically require higher outputs).
  • The size of your building and the number of rooms.
  • Your building’s insulation levels.

When Should You Install a New Boiler?

If you are spending upwards of £300 a year on boiler repairs, you may want to think about getting a new boiler. Here are a few signs that it’s time for a replacement:

  • Your current boiler is older than 10 years and has not been looked after properly.
  • You receive exorbitant heating bills each month.
  • You’ve noticed that your boiler makes strange noises, like high-pitched whistling or grinding.
  • You feel as though you are constantly spending money on boiler repair services, including fault finding and leaks.
  • It takes a long time for your hot water and radiators to heat up properly.

While some of the above problems are fixable, if your boiler issues persist, you need to invest in a new boiler. Older boilers have low-efficiency ratings, so upgrading to a more modern boiler could save you hundreds of pounds when it comes to your energy bills.

When is the best time of year to install a new boiler?

The best time of year to invest in a new boiler is during the warm, summer months. This way, you’ll be properly prepared for winter well ahead of time. Boiler engineers are usually not as busy during the summer months and you could also benefit from more competitive pricing.
