Frequently Asked Questions About Boiler Installation

What is a power flush, and do I need one for my new boiler?

A power flush is a deep cleaning of your central heating system, using specialized equipment to remove sludge, rust, and other debris that can build up over time. This buildup can restrict water flow, reduce heating efficiency, and cause damage to your boiler and other components.While not always strictly necessary with a new boiler, a power flush is often recommended, especially if you're replacing an older system. It ensures that your new boiler is installed in a clean and efficient system, maximizing its performance and lifespan. A clean system also helps reduce noise and improve heat distribution.Signs that you might need a power flush include cold spots on radiators, slow heating, frequent boiler breakdowns, or noises coming from your heating system. Discuss with your boiler installer whether a power flush is advisable for your specific situation.

What is a combi boiler?

A combi boiler (combination boiler) provides both central heating and domestic hot water on demand, directly from the mains water supply. Unlike conventional boiler systems, a combi boiler doesn't require a separate hot water cylinder or a cold water storage tank in the loft, which makes them compact and ideal for properties where space is limited. Combi boilers are very popular in flats and houses with less hot water requirements since they deliver hot water instantly to taps and showers. If you use a lot of hot water at once, the temperature and pressure may decrease; however, the hot water is readily and immediately replaced by more heated water.

What is the average lifespan of a boiler?

The average lifespan of a boiler is around 15 years, though well-maintained systems might last considerably longer. Regular servicing can extend the life of your boiler.. If your boiler is nearing or exceeding its expected lifespan, it might be less efficient and prone to breakdowns, making it a good idea to consider replacing it.

What are the signs that I need a new boiler?

Several signs can indicate it's time to replace your boiler :

• Your boiler is more than 15 years old:
Older boilers are much less efficient than modern condensing boilers and are more likely to break down, so upgrading to a new, energy-efficient boiler could save you significant amounts on your energy bills over time.
• Your boiler keeps breaking down:
If your boiler requires frequent repairs, it might be more cost-effective to replace it in the long run.
• Your energy bills are increasing:
An inefficient boiler uses more energy resulting in costly increases to your heating bills. Consider replacing it with an energy-efficient model.
• Your boiler is making strange noises:
Unusual banging, whistling, or gurgling sounds might mean there is a serious issue with your boiler and should be investigated by a qualified heating engineer.
• Your radiators are not heating up properly:
Radiators taking a long time to warm up, or some radiators not heating at all could indicate a boiler malfunction, air in the system, or circulation problems.
• Low water pressure:
Low water pressure might mean your boiler is not functioning optimally. Have a heating engineer inspect the system.
• Leaks or drips near your boiler:
If you notice leaks or drips around your boiler, it's important to get it checked by a professional immediately.
• Pilot light goes out frequently: A faulty pilot light is often a sign of bigger issues to come.
• Yellow flame instead of blue: A yellow flame on a gas boiler can mean there is incomplete combustion or a dangerous carbon monoxide leak. If you see a yellow flame, turn off the boiler and contact a qualified technician immediately..

If you are experiencing any of these issues, contact a qualified heating engineer for a boiler inspection and get advice on whether a replacement is necessary.
