New Boiler Guide, The cost for a new boiler replacement

The first thing you might think of when buying a new boiler is the possible cost. Boilers can be expensive but getting a good boiler is a good investment.

You will of course want your boiler to be efficient and to last for years to come.

The price for a new Boiler replacement can vary, depending on many crucial elements:

• The type of boiler you want to install in your house (e.g. combi, system or regular)
• Moving you boiler to a different location
• The model you aim to buy (e.g. mid-range vs. premium)
• Converting your current boiler with another type (e.g. system to combi)
• The extras you get (e.g. filters, a controller or smart thermostats)

Without a doubt, replacing your current combi boiler with another is cheaper than converting your system boiler to a combi boiler. Read our New Boiler Guide.

Converting your boiler requires more time, more labour and more materials. Not to mention how complex the whole process is.

Which model you pick also plays a huge role in determining the cost for a new boiler. Here at Let’s Heat, we offer some of the best brands in the boiler industry such as Alpha, Worcester Bosch and Viessmann.

With Let’s Heat, you can choose from the multiple ways of payment we offer to our customers. You can pay in cash or get a boiler finance plan that will enable you to pay monthly for your new boiler.

Some important factors to consider for a boiler replacement:

As has been noted, a new Boiler replacement might not be that cheap. So it’s important to consider some key factors before making your final decision.

The size of boiler you need (kW output)

To clarify, the higher the output of your boiler, the more powerful it will be. Nonetheless, it’s never a great idea to get the boiler with the highest output rating. A too high output rating would increase your energy bills. And a too low output rating will not meet your demand. Read our New Boiler Guide.

Through counting the number of bathrooms and radiators in your home, you can find the most appropriate output rating for you. This information can also help you have an idea of the level of demand for domestic hot water and central heating.

With this purpose in mind, we advise you to get a quote from a Gas Safe registered engineer. If you have a brand in mind, then you should check their website and guidelines. A lot of manufacturers, nowadays, offer advice on their websites.

Here is a table to guide you through what you need to know:

To point out, small homes with one bathroom and little or no space for a cylinder should consider getting a combi boiler.

Location of the new boiler

It will cost you less if you install your new boiler in the same location as the old one. Moreover, it will make the job more straightforward.

On the other hand, you can move your new boiler to a different location if you want to. But it goes without saying that you will have to pay more. 

The process of moving your boiler requires more work and materials. You will need a new flue installed and new pipework re-routing through your home. This process can be very messy though.

Energy efficiency 

If you want to reduce your carbon footprint, save some money and keep your house warm and fuzzy, then it’s important to get an energy-efficient boiler. 

At Let’s Heat, we offer modern A-rated boilers that can be bought with a smart thermostat in order to reduce energy wastage.

You can save about £340 and 1,500kg of carbon dioxide a year if you replace your old boiler with an A-rated boiler and set of heating controls according to the Energy Saving Trust.

Some replacement boiler installations take longer than others. Some are just more complicated than others.

For instance, replacing your combi boiler with another combi boiler might take around 1 day. 

Oh, the other hand, converting, for example, a combi boiler to a system boiler is probably going to take 2 days. Read our New Boiler Guide.

When should you replace your boiler?

Generally speaking, boilers are estimated to last around a decade (10 years). So if your boiler is that old, it’s a good sign that it’s time to replace it. Read our New Boiler Guide.

Additionally, there are other reasons as to why you should get a new boiler. These might be:

1. Your boiler is old and inefficient 

Boilers that are more than 10 years old are G-rated. They have an efficiency rating of around 70%. As a result, for every £1 you spend, 30p is wholly wasted. Modern boilers, on the other hand, are 90% efficient. 

2. Your boiler is too expensive to repair

In some cases, broken boilers are very costly to repair. Especially if you need to replace or repair parts like the PCB or the heat exchanger. In short, it might be more cost-effective for you to get a new boiler instead.

3. Moving your boiler 

If you want to change the location of your boiler, then it makes sense to get a new boiler installed with a brand new warranty.

4. Your boiler can’t meet hot water demands

It might be time to replace your boiler with a new model that has a higher power output if your current boiler is unable to meet your hot water demands.

What are the types of gas boiler replacement?

If you’re getting a new boiler, then you should know that there are three major types:

Combi boilers

• Their compact design makes them perfect for homes with limited space
• Do not require a hot water storage cylinder or a cold-water tank
• Unsuitable for larger homes with multiple bathrooms and a high demand for hot water
• Not suitable for areas with low mains water pressure

Regular (heat only) boilers

• Good for homes with multiple bathrooms and a high hot water demand 
• Perfect for areas with low water pressure from the mains
• Suitable for homes with older heating systems that may not be able to tolerate high pressure
• They take space since they need a cistern tank
• A tank in the attic can freeze in winter and might cause many problems if it starts leaking

System boilers

• Also recommend for homes with more than one bathroom and a high demand for hot water
• Do not need a tank in the attic
• Internal components can make installation much easier.
• Unsuitable for areas with low water pressure 
• Not suitable for homes with traditional heating systems that can’t tolerate high water pressure 
• You need to consider where to put the water tank if a system boiler is replacing your combi boiler.

What is meant by a Condensing Boiler?

The terms condensing and non-condensing can be confusing to people shopping for a new boiler. Read our New Boiler Guide.

Presently, it is stated by law that new boilers must use condensing technology. In short, you don’t have to worry about getting a condensing boiler.

Condensing is not a type of boiler, but rather technical feature. In a Condensing boiler, you get a much bigger heat exchanger. They also produce additional heat from the fuel. The same fuel that would have been wasted in a non- Condensing boiler. As a result, they are more efficient.

non-condensing boilers are less efficient by 50% since a lot of heat was lost in the combustion exhaust gases. On the other hand, new boilers would capture this heat and use it to heat water.

condensing boilers are energy efficient by 90%. They use excess energy to heat your property. Not to mention, they are environmentally friendly and reduce your heating bill.
