Countless UK homes and businesses are making the switch to energy-efficient boilers for the sake of the environment and to save on monthly costs.

If you’re planning to do the same, not only is it important to choose the right type of boiler, but to get experts to assist you with your boiler installation in Dewsbury.

This is where Eco Happy comes in. We’ve helped thousands of homes and businesses navigate the complexities of boiler installation, ensuring they can start reaping the rewards sooner rather than later.

What Type of Boiler Do You Need?

There are a number of factors to consider before you invest in a boiler. The size of your home, existing insulation, hot water requirements and your budget are just a few of the considerations.

To help make this decision a little easier, let’s look at the different types of boilers that are available to you.

Conventional boiler

Conventional boilers are what you would originally find in most UK homes, but they are slowly being phased out due to the high levels of carbon emissions they produce.

Conventional boilers consist of a boiler unit, hot water cylinder and expansion tank. Water is heated in the boiler and then stored in the hot water cylinder until it’s needed. Even though these boilers are ideal for homes with high hot water demands and they can serve multiple bathrooms and taps at once, they’re not the best long-term investment.

Combi boiler

Combi boilers have become a popular choice among homeowners because of how energy-efficient they are.

These boilers heat water on demand, which means they are ideal for single-bathroom households that have low hot water demands. Homeowners can choose between an electric and gas combi boiler. However, gas is the more affordable option.

Electric boiler

Electric boilers are compact and do not require a flue or exhaust, making them ideal for smaller spaces or apartments where gas boiler installation might be impractical.

These boilers also have fewer moving parts, which means less maintenance is generally required. When paired with other renewable energy sources, such as solar panels, electric boilers can be an efficient hot water and home heating source.

System boiler

Homes and businesses with high hot water demands would benefit from a system boiler as they can run multiple taps and showers at once.

The only downside with a system boiler is that it takes up more space because they require storage tanks, so larger properties would be a better fit. System boilers can run on electricity, liquefied petroleum gas and natural gas, which can help with cost savings.

Biomass boiler

If environmental impact and fuel availability are important to you, a biomass boiler is another option.

Properties that have high heating demands, such as larger homes, multi-building properties, farms, or commercial premises, can benefit from biomass boilers. Biomass boilers are ideal in areas with ready access to fuel sources like wood pellets, chips, or logs.

How Much Does It Cost To Install A New Boiler In Dewsbury?

The cost of a new boiler installation depends on the type of boiler you decide on, the complexity of the installation and your existing boiler system.

Fortunately, UK homeowners and businesses can also take advantage of several boiler upgrade schemes, including the Boiler Upgrade Scheme (BUS), the Home Upgrade Grant (HUG) and the Warm Home Discount Scheme.

Here’s a general idea of the costs you can expect:

What Size Boiler Do You Need?

Boiler size is another factor that needs to be considered prior to installation. Most boilers have an output range of: 

  • 24-27 kW
  • 28-34 kW 
  • 35-42 kW 

The size of your home as well as the number of radiators you have will determine what size boiler you require.

Below are general guidelines for the approximate boiler sizes needed for various residential and commercial properties.

When Should You Install a New Boiler?

Many people don’t realise that there is an ideal time to get a new boiler installation. It’s also important to know when to install a new system based on issues you’re experiencing with your existing boiler. 

If you’re noticing any of the following issues, you should consider installing a new boiler:

  • Strange noises: Unusual sounds like banging, whistling, or gurgling could mean you have air in the system, low water pressure, or imminent pump failure.
  • Poor efficiency: If your heating seems inadequate or if it takes longer than usual for your radiators to warm up, this might mean your boiler is not operating efficiently.
  • Unpleasant smells: If you notice unpleasant smells such as gas, it’s important to switch your boiler off immediately and contact a professional about a replacement.
  • Increased repair costs: Boiler repairs that cost you £150 or more per year are a clear sign that it’s time to replace your boiler.
  • Pilot light issues: A pilot light that keeps going out or appears yellow instead of blue can indicate a serious problem.
  • Higher fuel bills: An unexpected rise in your energy bills could suggest your boiler is no longer producing heat as efficiently as before.

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

The best time for boiler installation is during the spring and summer months. During these times, there’s typically less demand for heating, meaning heating engineers and installers are less busy. This can make it easier to schedule an installation, and you might even benefit from off-peak discounts.

Installing a new boiler during the warmer months also helps ensure that your central heating system is fully functional and efficient by the time colder weather arrives. This can help you avoid the discomfort and urgency of having to replace a failing boiler during the cold season when you need heating the most.

FAQs

What should I do with my old boiler?

The engineer who installs your boiler may be able to assist you with the disposal of your older model. If not, you can always contact your local council to take it away for you. As a last resort, you can take your boiler to a scrap yard to be recycled.

How do I know if my boiler is too big for my home?

You can usually tell if your boiler is too big if it runs for short cycles of time and turns off. Make sure that you check your heating requirements and the output of the boiler you’re considering prior to installation.

How long do combi boiler installations take?

Combi boiler installations tend to take around four to six hours and will include the removal of your older model. Installation times can vary should additional processes need to be carried out, such as a power flush.
