What Type Of Boiler Do You Need?

Read on to decide which of the boilers listed below best suit the needs of your home or business.

Combi boiler

Combi boilers provide heat to water outlets and central heating systems from one single unit and can be fueled with either gas or electricity. These nifty little systems are ideal for houses, flats and offices with one bathroom. Combi boilers are efficient, compact, easy to install and have hot water instantly available. Water is taken directly from the mains, so good water pressure is needed.

The use of multiple appliances is not possible with combi boilers, and the lack of an immersion heater means that there is no backup if your boiler were to break down. It’s also important to note that combi boilers are not compatible with power showers.

system boiler

System boiler

These boilers are perfect for larger commercial businesses and homes with multiple bathrooms. A heat exchanger provides hot water to outlets and heating systems within your property. System boilers can be either LPG, gas or electric, but can also run on solar power. Adequate water pressure is required as the water supply is taken directly from the mains.

A separate storage cylinder means that hot water can be supplied to multiple areas and appliances simultaneously. System boilers are a great option for businesses and households with high heating demands.

Unlike combi boilers, hot water is not instant and needs at least 30 minutes to heat up if the timer has not been set. If the water in the cylinder has run out, additional time is needed for the new supply to heat up.

Conventional boiler

Also known as “traditional boilers” or “heat-only boilers”. These are the oldest models on the market. Despite being widely used throughout the UK, they are being phased out due to their high rate of carbon emissions. This is a result of their need for oil or Liquefied Petroleum Gas (LPG) to operate.

Conventional boilers have a more complex installation process and require both hot and cold water tanks. Traditional boilers are suited to homes or businesses with high heat demands but might be made obsolete in keeping with the UK’s Net Zero drive.

electric boiler

Electric boiler

These boilers work very much like an electric kettle. An internal heating element within the boiler heats up the surrounding water. Electric boilers are highly efficient (up to 99%), have low installation costs, and have fewer components than a traditional gas boiler which means lower maintenance.

These systems are environmentally friendly and are known for operating quietly. Electric boilers are best suited to smaller properties and businesses. It is worth noting that the running costs of these boilers tend to be higher than conventional boilers, but they are compatible with solar panels.

Biomass boiler

Biomass boilers supply heat to central heating systems and hot water boilers by burning specialised organic materials. These materials are either wood chips, pellets or logs and are considered to be a carbon-neutral fuel source. Biomass boilers are reliable and have an efficiency of up to 97%.

They are perfect for bigger homes and businesses with high heat demands and large heat delivery systems such as underfloor heating. Large areas are required for the installation of these boilers as well as storage for the fuel.

The running costs of a biomass boiler are relatively low in comparison to gas boilers, however, the installation costs are around the £18,000 mark.

How Much Does It Cost To Install A New Boiler In Birstall, West Yorkshire?

The costs of installing a new boiler will depend on more than the type of boiler. Existing traditional boiler systems can entail a complex removal process. The disconnecting and removal of pipes along with the installation of new systems mean additional labour costs.

Below, we have provided estimated costs for installing new boilers in both homes and businesses.

What Size Boiler Do You Need?

When discussing boiler sizes, we are referring to the kW output and not their physical size. Standard boiler sizes range between 10kW and 70kW which is the range for domestic and commercial use. As discussed, anything above 70kW is industrial.

When determining the optimum boiler size for your property, you should consider certain factors. For example, poor insulation would need to be offset by a larger boiler to combat heat leaks.

Likewise, a higher number of radiators, bedrooms and bathrooms will also need a higher power output to meet heating demands.

Below, we’ve provided estimated boiler sizes appropriate for various types and sizes of properties.

What does a boiler servicing include?

The specific checks will depend on the type of boiler. Gas boilers for example will have more areas and components that require inspection compared to a combi boiler. In general, things that are checked during this procedure include:

  • Visual inspection of the unit.
  • If the boiler isn’t already on, it will be fired up to check that water is being heated.
  • Removal of the casing to inspect internal components and check for corrosion, faults and weak points.
  • Flue checks if required.
  • Gas pressure checks if required.
  • Checking of boiler controls and the area surrounding the unit.

What if my property is poorly insulated?

As previously mentioned, poorly insulated properties will require boilers with a larger power output. However, heating engineers should check the insulation quality of the property and may advise that certain implementations be carried out to ensure that your boiler’s heat is being optimised.

How long does it take to Install a new boiler?

Boiler installation can vary between 6 hours to four days. This is determined by the boiler type, size and the removal of existing boiler systems. Some commercial and industrial installations are larger and more complex jobs which require more time.
