Frequently Asked Questions About Boiler Installation

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:
Frequent service calls might mean it's time for a new boiler.
• 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 could indicate a problem with your boiler and require professional service.
• 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: If you have an older boiler and the pilot light goes out frequently, it may need to be repaired or replaced. .
• Yellow flame instead of blue: A yellow flame on a gas boiler can mean there is incomplete combustion or a dangerous carbon monoxide leak. Seek immediate assistance from a qualified professional.

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.

How do I turn off my boiler?

To turn off your boiler, consult your boiler's manual for specific instructions, but most boilers are turned off at the main control panel. Ensure you understand which controls are for hot water and which are for central heating.

How do I repressurize my boiler?

If the pressure gauge on your boiler is reading below 1 bar, you'll need to add water to the system. Consult your boiler's manual for specific instructions, or follow these general steps::1. Turn off your boiler and allow it to cool.2. Locate the filling loop. This is usually a flexible braided hose connected to your mains water supply and boiler, under the unit. Sometimes, the loop is built in; other times, it is external. 3. Open both valves on the filling loop slowly, If your boiler uses a lever-type handle, consult the manual. Listen for the sound of filling.4. Keep an eye on the pressure gauge. When the pressure reaches the appropriate pressure, close both valves on the filling loop firmly.5. Turn your boiler back on. If the pressure is still low, repeat the process.. If you're not sure how to repressurize your boiler, it's best to consult a professional. Incorrectly repressurizing the system can cause damage.

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. They are much smaller than traditional boilers, saving valuable space. 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.
