GuidesReplacing your boiler can be a stressful and costly process. That’s why we have written this helpful article to show you your options when it comes to buying a new boiler.
Has your boiler stopped working, then you are now in need of a replacement, you should consider replacing it with a combi boiler if you haven't already got one.
Combi boilers are a brilliant replacement for when you want to increase efficiency and space in your home. We have a great range of best combi boilers available through iHeat.

A combi or combination boiler combines a water heating system and central heating unit into a single body, acting as a unified way to handle heating and hot water without needing two separate boilers and produces hot water on demand.
This means there is no need for a separate water tank system and therefore takes up much less space in your home, which is a major benefit for smaller homes.
Another great benefit of a combi boiler is its efficiency. By heating water on demand as opposed to constantly heating stored water, you can save energy and cut costs on your fuel bills.
A new combi boiler should be around 90% efficient, so replacing your old boiler could save you up to £300 according to The Energy Saving Trust.

The efficiency of your boiler plays an important role in how well your boiler operates as well as the cost of your fuel bills.
The higher the efficiency of your boiler, the lower your fuel costs. The Energy Saving Trust estimates that you could save up to £300 a year by replacing your old inefficient boiler with a new A-rated one (90%+ efficient).
All iHeat boilers are A-rated for efficiency, so you know you can rely on us to help you save money and reduce your carbon footprint.
Paying for a boiler on finance spreads out the cost to make it more affordable on a monthly basis instead of paying for it all at once.
With iHeat you can buy a brand new boiler on finance using our super simple to use website with an instant quote and fixed price.
We offer great plans such as 0% APR for 2 years or as little as £10.32/month for 10 years. These prices include the boiler, installation and up to 10 Years Warranty which is activated by the installer as soon as the job is done.
At iHeat, we’re happy to move your boiler from one place in your home to another, providing it is practical.
For example, if your old boiler was taking up far too much room in your kitchen cupboard, you can replace it with a boiler that fits in your airing cupboard. However, you should consider if moving your boiler is worth the extra labour cost.
When we talk about boiler size, we’re often referring to the output in kilowatts (kW) as opposed to the physical dimensions of the boiler itself. Kilowatts are the measurement of energy that is output by the boiler in the form of heat.
The right kW boiler for your home depends on a number of factors, including your demand for hot water, the number of bedrooms, bathrooms and radiators.
In general, the higher your demand for heat and hot water, the higher the output you will need.
Size of Home | No of Bedrooms | No of Bathrooms | No of Radiators | Boiler Size |
Flat / Bungalow | 1-2 | 1 | Up to 10 | 24-29kw |
Medium terrace/semi-detached | 3-4 | 1-2 | Up to 15 | 30-35kW |
Large semi-detached/detached | 4+ | 2+ | Up to 20 | 35-43kW |
Considering these options before buying a new boiler can really help you to save money on the boiler, installation and fuel bills that follow.

The average cost of a new combi boiler in the UK is between £1,800 and £3,500, including installation, depending on the brand and model.
A typical combi boiler service in the UK costs around £80 to £120, depending on your location and the company providing the service.
Plumbers typically charge between £500 and £1,500 for the labour to replace a boiler, depending on the complexity of the job and location.
A combi boiler usually needs replacing every 10 to 15 years, depending on its condition, maintenance, and overall efficiency.
Combi boilers are being phased out as part of the UK's drive toward renewable energy and more environmentally friendly heating solutions, such as heat pumps.
If your 10-year-old combi boiler is showing signs of inefficiency, frequent breakdowns, or rising energy costs, it may be worth considering a replacement for better performance and savings.
Switching to a combi boiler can be a significant job, especially if you're changing from a conventional system. It typically involves removing tanks and reworking pipes, taking 1-3 days to complete.
