Combi Boiler Installation

 

A combi boiler is an energy-efficient and space-saving solution that has become increasingly popular among homeowners. This versatile heating system combines a central heating unit and a high-efficiency water heater in a single compact unit.

If you are considering a new boiler for your home, this guide will help you understand various aspects of combi boilers, such as new boiler costs, combi boiler installation cost, maintenance, and repair.

What Is a Combi Boiler?

A combi boiler is a compact, high-efficiency heating system that serves a dual purpose: providing both central heating and hot water for a home or building. Unlike traditional boiler systems that require separate water storage tanks for hot water and central heating, a combi boiler directly heats the water from the mains supply as it is needed, eliminating the need for a separate hot water storage tank or cylinder.

The key advantages of a combi boiler include:

Space-saving: Since they don’t require a separate hot water storage tank, combi boilers are ideal for smaller homes or areas with limited space.

Energy efficiency: Combi boilers are typically more energy-efficient than traditional boiler systems, as they only heat the water when it is needed, reducing heat loss from stored hot water.

Cost-effective: Combi boilers can be more cost-effective to install and maintain because they have fewer components than traditional systems.

Convenience: Hot water is available on demand, with no need to wait for a tank to heat up.

Combi boilers last between 10-15 years.

New Combi Boiler Installation and Replacement

When it comes to purchasing a new combi boiler, the cost is a significant factor to consider. Additionally, combi boiler installation requires a skilled professional to ensure the system functions correctly and safely. Combi boiler prices can vary greatly depending on the brand, size, and efficiency of the unit.

Most Common Combi Boiler Problems and How to Solve Them

We understand how important it is to have a functioning boiler, especially during the colder months. Our expert plumbers are trained to handle a wide range of boiler issues, including:

Low Combi Boiler Pressure:

Appropriate pressure is crucial for your boiler to maintain the water flow throughout the system. If the pressure drops too low, the boiler often locks out and displays a low-pressure error code. Checking the pressure gauge usually reveals low pressure.

An issue may be present if the pressure gauge on your boiler indicates less than one.

Potential causes for low boiler pressure include water leaks, malfunctioning valves, or bleeding radiators.

Solution: Assessing the boiler pressure is quite straightforward; just examine the built-in pressure gauge. If the needle falls below 1, it signifies low boiler pressure, which is likely affecting the proper functioning of your central heating system.

Inspect the boiler for any visible leaks. If you find any, reach out to a certified engineer. If no leaks are present, reset the boiler pressure according to the instructions provided in your boiler’s manual.

Radiators Not Heating:

Have you observed that your radiators aren’t as warm as they once were?

When radiators have cold areas at the bottom or inconsistent heat distribution, it’s typically due to excess air or an accumulation of sludge.

Solution: Try bleeding the radiators. If this doesn’t help, the system might need to be flushed by a certified central heating technician. Avoid trying to remove the sludge yourself. Reach out to a heating expert who can utilise chemical flushing to cleanse the system and remove the sludge.

Boiler Making Strange Noises:

A mild humming sound is a common noise emitted by the boiler. However, if your boiler makes a noise similar to a boiling kettle, an accumulation of sediment or scale is likely to obstruct the water flow. This issue is particularly prevalent in regions with hard water.

Solution: Luckily, these issues can be resolved fairly easily through regular boiler upkeep or when they occur.

During your annual combi boiler service or as required, a boiler technician can cleanse your system using chemical treatments and high pressure to enhance the quality of the water. At Atapos Heating, we offer a limescale filter to prevent mineral deposit buildup.

No Hot Water:

The diverter valve filters hot water before it reaches the faucets and is responsible for heating as well. Initially, the hot water is directed towards the taps, and when they are closed, it heats the home.

Over time, the buildup of sediment and debris can clog the valve, affecting the hot water supply.

Solution: To address this problem, contact a heating specialist who can perform a chemical flush to clear the blockage.
