Back Boiler To Combi Conversion

Install a combination boiler to remove and replace a back boiler, hot water tank, and loft
tanks. This upgrade creates extra storage space by eliminating the back boiler, hot water
tank and water storage tanks in the loft. 

A combination boiler typically increases water pressure to mains water pressure. BoilerMax engineers will power flush your existing radiators, ensuring optimal results for your heating system.

BACK BOILER TO COMBI CONVERSION

Upgrade your heating system with our expert back boiler to combi boiler conversion services. We specialize

A back boiler to combi conversion involves removing an old back boiler system and replacing it with a combi boiler.

Combi boilers are more energy-efficient, compact, and provide hot water on demand unlike back boilers which need a hot water storage tank.

The cost can vary depending on the complexity of the installation, but it’s typically in the range of £2,500 – £4,500.

The process can take anywhere from 2 to 3 days depending on the complexity of the installation.

No, the conversion involves gas plumbing and should only be carried out by a Gas Safe registered engineer.

The new combi boiler is typically installed in a kitchen or utility room, but the location can vary depending on your property.

The old back boiler is usually removed and disposed of by your heating engineer as part of the conversion process.

While combi boilers have many advantages, they may not be suitable for all properties. For example, if you have multiple bathrooms and people often use them simultaneously, a system boiler or regular boiler may be a better choice.

There will be some disruption, such as noise and dust, but a professional heating engineer will aim to keep this to a minimum.

Combi boilers are more energy-efficient, require less space, and provide hot water on demand. They also tend to have fewer moving parts, which can mean they are less likely to break down.

  • Converting a back boiler to a combi boiler involves several steps and is typically done by a professional heating engineer. Here’s a general overview of the process:

    1. Removal of the Old Boiler: The first step is to remove the old back boiler, which is often located behind a fireplace. This can be a complex job that involves carefully dismantling the fireplace and removing the boiler without causing damage.

    2. Drain the Heating System: Before the new boiler can be installed, the existing heating system must be drained of all water.

    3. Installation of the New Combi Boiler: The new combi boiler will typically be installed in a different location, such as a kitchen or utility room. It needs to be connected to the gas supply, the water supply, and the heating system.

    4. Connection to the Flue: The combi boiler needs to be connected to a flue, which allows waste gases to be safely vented outside.

    5. Testing: Once the new boiler is installed and connected, it needs to be tested to make sure it’s working correctly and safely.

    Remember, this is a significant job that involves gas plumbing and should only be carried out by a Gas Safe registered engineer. The cost for converting a back boiler to a combi boiler can vary, but it’s typically in the range of £2,500 – £4,500.

    Please note that while combi boilers have many advantages, such as being more energy-efficient and providing hot water on demand, they may not be suitable for all properties. For example, if you have multiple bathrooms and people often use them simultaneously, a system boiler or regular boiler may be a better choice.

    Before making a decision, it’s recommended to take advice from a professional heating engineer who can assess your property and recommend the best solution for your needs.
