What Type Of Boiler Do You Need?

Combi boiler

Combi or combination boilers combine water and space heating into a single, compact design. Combis differ from traditional boilers because they don’t need a separate tank for hot water storage. These boilers simply heat water from the main water supply whenever hot water is needed. They are usually powered electrically or with gas.

Combi boilers are best for smaller homes with low hot water demands.

They are the most energy-efficient boilers on the market because they heat water and rooms only as needed. Because of their minimal parts and piping, combis are also the most affordable to install.

System boiler

System boilers work similarly to combi boilers. They heat water from a main water supply and store it in separate hot water tank, ready for use.

System boilers are best for larger properties, with many bathrooms requiring a significant amount of hot water. They are also ideal for medium and large businesses with multiple hot water faucets.  System boilers are quite large and take up considerable space as they need space for the hot water tank.

Various materials can fuel system boilers, including gas, electricity, and liquified petroleum gas (LPG). However, natural gas is the most common fuel for system boilers.

Conventional boiler

Conventional or regular/traditional boilers are common central heating systems in older homes and are among the most used heating systems in the UK. They have more parts than a combi or system boiler, including a hot water and cold water cylinder, which take up a lot of space. 

Conventional boilers are known for being reliable and robust in heating large residential and commercial properties with multiple faucets and radiators. However, they aren’t the most energy-efficient as they are powered mainly by oil or liquified petroleum gas.

Conventional boilers constantly run, heating water even when not needed. They are also being slowly phased out because of their negative environmental impact, specifically due to their carbon emissions. This has motivated households and businesses to invest in a better long-term plan and replace their existing conventional boilers with more sustainable ones. These include system boilers (for commercial properties) or combi boilers (for smaller homes).

electric boiler

Electric boiler

Electric boilers run solely on electricity to generate heat, making them highly energy-efficient. An electric boiler is a great option if you want to replace your existing conventional boiler with a fossil-fuel-free heating solution. 

Electric boilers are compact and extremely quiet when compared to other boiler types. The only downside to consider with an electric boiler is the running costs.  However, using an electric boiler can be cost-effective if you use renewable power sources like solar or wind generators. 

Consider replacing your home or apartment boiler with an electric boiler. The energy and cost efficiency will be worth the switch.

Biomass boiler

Biomass boilers are heating systems fueled by renewable materials like wood, wood chips, or wood pellets. They are one of the most environmentally friendly and sustainable boilers because they don’t use fossil fuels. They are slightly larger than gas or electric boilers, as they must accommodate a separate compartment where the natural material burns as fuel to produce heat.

Because of its size and heat output, a biomass boiler would be best for commercial properties, which have greater heating demands but also have the space for a larger boiler type.

How Much Does It Cost To Install A New Boiler In Horsforth, UK?

The cost of a new boiler in Horsforth will depend on several factors, including:

  • The type of boiler you are installing 
  • How complicated the installation will be
  • Whether you are replacing your boiler with the same type as your current boiler.
    For example, replacing a conventional boiler with a combination boiler is much more complicated than replacing like-for-like, which will increase the cost.

Below is a table with average costs for new boiler installations for homes and commercial businesses.

Large Business

Larger businesses will need much more powerful boilers than small or medium-sized businesses. They are estimated to require heating over 250 rooms resulting in a high demand for hot water. Large businesses require boilers that generate power outputs between 100 and 200 kW. This is why installing boilers in large businesses is normally quadruple the cost of small or medium-sized businesses.

A Gas Safe registered heating engineer is the best choice for boiler installations. You should never try to install a boiler yourself, nor should your plumber install your boiler!

The lifespan of a boiler is estimated at around 10-15 years. This is just an average; some boilers may last longer if you regularly service them. Regardless, replace your boiler as soon as you notice that repairs are becoming too regular or more expensive than purchasing a new boiler. This will save you money in the long run.

A quick swap out and installation of the same boiler in the same position on the property will take 4-6 hours. For more complex installations, like installing a new type of boiler to your old one or changing the location of the boiler, this could take 1-4 days.

Boiler installation costs vary depending on the type of boiler you have installed. However, the average range is from about £2750 to £2790 for a combi, system, conventional or electric boiler. A more complicated boiler, like a biomass boiler, can cost up to £16000 to install.
