The first rule anyone looking to purchase a new boiler should know is that you should always use a Gas Safe registered installer for any boiler replacement, this will ensure that your warranty is valid and accurate.
A lot of home owners will be tempted to go for the cheapest models in order to cut corners and save their money. This isn’t the right way to approach this situation. You should, however, carefully consider which brand you want to purchase as performance and reliability can vary between different brands.
We’ve designed this guide to buying a new boiler to help you to understand the basic costs involved in purchasing different types of gas boilers. We’ll walk you through all the important areas that impact your when looking for a new boiler; not just the initial outlay but also maintenance and operating costs.
How Much Does an Installation Cost?
There are always pros and cons when buying something new, especially something as important as a boiler or heating system. In such circumstances it may be a good idea to consult a Gas Safe registered installer who can guide you to the right decision.
Conventional Boiler Costs
- They send water to lots of taps at the same time, without the flow of water getting weaker.
- You get a cold-water tank and hot water cylinder as well.
- We can fit an electrical immersion heater to the hot water cylinder at the same time we install your new boiler. Then you’ve got a back-up, just in case your boiler breaks down.
- They particularly suit larger homes that have more than one bathroom.
Conventional boilers are typically found in older homes that already have a traditional heating and hot water system. Typically, if you already have one fitted, your conventional boiler replacement should cost between £1,500 and £2,500.
System Boiler Costs
In a system boiler, cold water enters the boiler directly from the mains supply. The water is heated via a heat exchanger, which transfers energy from the gas jets to the water. Once heated, the water is pumped to the hot water cylinder, where it is stored until required. Because there is a large reservoir of hot water always available, a steady supply can be maintained even if multiple taps or showers are in use.
If you already have a boiler fitted, then your boiler replacement should cost between £1,600 and £3,000.
If you are replacing your boiler, then the new boiler costs will be less if you chose a system boiler over a conventional boiler. This is because you won’t need to fit a cold-water storage tank in your loft. As a rule of thumb, you should expect to pay £2,000 – £3,500 for a new install.
Combination Boiler Installation
A combination or ‘combi’ boiler is both a high efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold-water storage tank in the roof space.
They are also very cost-effective and energy-efficient as water is heated instantly rather than being heated and then stored in a cylinder. An added benefit is that hot water is delivered at mains pressure, which means that you could get a powerful shower without the need for a separate pump.
How to Save Money
When buying a new boiler, it’s also important to think about ways you will be able to save money on energy bills and general maintenance. The Energy Saving Trust estimate that replacing your old boiler with a brand-new unit could lead to savings of £340 per annum and remove up to 1500kg of Co2 from your annual carbon footprint. A new boiler cost of £1500 could be paid off in less than five years whilst also helping the environment.
Always make sure to check your installer before buying a new boiler. Getting a wide range of quotes and references really will minimise the risk of problems later down the line and helps you get the best deal on a new boiler.
