iHeat New Boiler Costs

Boilers can be a daunting purchase for many people as they’re an appliance with a lot of responsibility, providing heat for you and your family is something you want to get right. Boilers aren’t exactly a quickly disposable item either, potentially lasting you a decade.

Effectively, new boiler cost can be split into two segments: the first is the actual boiler itself (unit price), and the second is the cost of the boiler being installed (set up) in your property by an expert engineer. 

Here at iHeat, we want to remove all of this undue stress and make the decision making process of upgrading to a new central heating system, as easy as possible.

Boiler costs can vary depending on a number of factors including their brand, model, fuel, output, warranty, labour and installation type. Typically a new boiler will cost between £1,845 and £3,500, below is a list of average boiler installations offered by iHeat (guide only).

Are ATAG Boilers Energy Efficient?

This efficiency can help reduce household energy bills and lower the home's carbon emissions, aligning with both economic and environmental benefits.

Why Does My ATAG Boiler Keep Losing Pressure?

If your ATAG boiler keeps losing pressure, it could be due to several reasons such as leaks in the heating system, a faulty boiler component (like the pressure relief valve), or issues with the expansion vessel. Sometimes, the problem can be as simple as needing to repressurize the system after bleeding radiators. However, if the pressure loss is rapid or recurrent, it's advisable to contact a certified engineer to diagnose and resolve the underlying issue to prevent further damage or inefficiency.
