Prices of boilers are dependent on many factors, from the type of boiler you need to the size of your home.

If looked after properly, the average lifespan of a system boiler is around 10-15 years. Regular boiler servicing is advised as it can mean your boiler should last longer.
We'd recommend replacing your boiler when repairs get too expensive as this should then be more economical and save you money long-term.
Some other signs to look out for are:
- It's making noises. Gurgling, hissing, whistling and banging can be a sign something is wrong and might be a build-up of sludge.
- The flame isn't blue. Your boiler flame should be blue so if it is orange, yellow or white then the oil is not burning properly. This can also be a sign that there is dirt in the burner or that your boiler is producing carbon monoxide and you should contact a heating engineer.
When replacing your boiler, it might also be time to replace your hot water cylinder or upgrade its insulation. If you're not sure whether your system boiler and/or hot water cylinder could do with an upgrade, get in touch with us and our experienced engineers can talk through your options.
We recommend a system boiler is serviced at least once a year to ensure it is functioning safely and efficiently.
Servicing your boiler will help diagnose any faults that may appear throughout the year, possibly preventing problems or heading-off long-term issues to your boiler.
An annual service is also ideal to ensure any warranties or guarantees are still valid.
If you're not sure whether your boiler needs to be serviced, or if you'd like to arrange a boiler service get in touch with us and our experienced engineers can talk through your options.
Yes, you can switch your system boiler to a combi boiler. Making the switch could save you space, time, money, and energy.
Here’s a brief overview of the process:
Consider Your Needs: If you have a system boiler with a water tank in the loft and need more space, a combi boiler might be a good option. However, be aware that a combi boiler might not be suitable if you have low water pressure. Our heating engineers can advise you further.
Get Quotes: Compare boiler prices and get a quote to understand the costs involved.
Consult an Expert: Discuss your heating and hot water usage patterns with one of our expert heating engineers to choose the right boiler.
Installation Process:
- Drain the existing system.
- Remove the old boiler, tanks, and controls.
- Install the new combi boiler and filters.
- Perform a chemical flush on the entire system.
Switching to a combi boiler can be done. To discuss your needs further and to find out if changing your boiler is suitable for your home, contact us today.
A hot water cylinder in a system boiler is a storage tank specifically designed to hold hot water for domestic use. It works in conjunction with the system boiler, which heats water and then stores it in the cylinder until needed. This setup ensures a ready supply of hot water for multiple taps and showers simultaneously.
The cylinder is typically well-insulated to maintain the water temperature, improving energy efficiency. Unlike combi boilers, which heat water on demand, system boilers with hot water cylinders can provide hot water at higher pressure and in greater volumes, making them ideal for larger households.
A hot water cylinder is typically installed in an airing cupboard, a utility room, or a dedicated cupboard within the home. The exact location depends on the layout of the house and the plumbing system. Ideally, it should be placed centrally to minimize heat loss and ensure efficient distribution of hot water to various taps and showers. If space allows, placing it close to the system boiler can reduce the amount of pipework needed, further enhancing efficiency.
