Factors That Affect the Installation Cost

Several factors can affect the installation cost. Some of these are detailed below:

Do You Need a Filter Fitted?

A boiler filter, often referred to as a magnetic boiler filter or system filter, is a device installed on the pipework of the central heating system.

Its primary function is to capture any debris, sludge, or rust that circulates through the system. This debris, if left unchecked, can cause significant damage to the boiler and reduce its efficiency.

The price of the filter varies depending on the brand, quality, and specifications. High-efficiency filters with advanced features tend to be more expensive.

Is a Thermostat Needed?

A thermostat is a device that controls the heating system in a home, allowing users to set the desired temperature.

Modern thermostats range from basic models that simply control heating settings to advanced smart thermostats that offer a range of features like remote control, learning capabilities, and energy usage tracking.

Thermostats vary widely in price. Basic models are relatively inexpensive, while smart thermostats, which offer features like Wi-Fi connectivity, programmability, and integration with home automation systems, are more costly.

Where is the Flue Situated?

The flue is a critical component in the installation of a boiler, especially for gas boilers, as it safely channels exhaust gases (such as carbon monoxide) away from the boiler and out of the building.

There are different types of flues, such as standard horizontal flues, vertical flues, and flue extensions. The type of flue needed depends on where the boiler is located and where the gases can be safely vented.

For example, a vertical flue, which exits through the roof, is typically more expensive than a standard horizontal flue that exits through a wall.

Baxi Reviews

Boxi has a great reputation throughout the UK, with a 4.6 rating from 54,713 reviews (as of 31 Jan 2024). Plenty of boiler fitters use Baxi as their number 1 choice of boilers.

Be sure that your boiler has an extensive warranty and don’t pay the minimum just because you can. Cheaper models may not last as long and may not be cost beneficial over the long run.
