Determining the cost of replacing a gas boiler isn’t always straightforward. Several factors impact the price. Let’s break it down simply.

- Installation location: Internal wall installs tend to be more expensive than external wall installs.
- Pipe upgrades: Undersized gas pipes may need upgrading which adds to the cost.

Factors to Consider When Replacing with a Combination Boiler
While the cost estimates provided above give a general idea of prices, there are some additional factors that may affect the quote. Choosing a combination boiler requires paying attention to a few key elements.
Gas Pipe Size: If your current boiler’s output is below 24KW, the gas line may need upgrading. Combination boilers heat water instantly on demand, requiring a sizeable energy output. The pipe’s size, proximity to the meter, and other appliances must support the increased demand.
Removing the Hot Water Cylinder: Combination boilers eliminate the need for stored hot water storage. However, repiping will be needed to redirect the hot water line from the cylinder location to the new combi unit.
Hot Water Demand: Combination boilers work best for small homes and families. Higher demand households may find the 10-15 liter per minute flow rate inadequate, especially during morning showertime rushes.
Incoming Water Pressure: Combi units require minimum inlet pressure and flow to operate. A pump is often needed to meet specifications.
Electric Showers: If you have an electric shower, consider upgrading to a mixer model for better compatibility with an on-demand hot water system.
Considering these additional elements will help develop a more accurate quote and ensure a combination boiler is the right choice for your specific needs.
