When should you replace your boiler with a new boiler?
With regular servicing, some models can withstand many years of use.
However, there are some circumstances where the overall cost of repairs determines that a new boiler installation is a must.
Here are some issues to look out for:
- Your heating bills are suddenly more expensive, with no explanation.
- Frequent issues require you to have it serviced more than once a year.
- Your boiler and radiators are making unusual noises.
- Your boiler smells sulphurous when it’s on.
- Your boiler leaks.
- Replacement parts are expensive and hard to find.
If you’re experiencing any of these major issues, it may be time to say out with the old, and in with the new.
In that case, it’s time to call us for a replacement boiler.
What type of new boiler should you choose?
After you’ve decided new boiler offers is the right decision for you, make sure you consider what boiler will be most efficient for your home needs.
Help with a new boiler is always available at Boiler Central but below we have listed some of the main features to look out for.
The main things to factor into your decision are:
- Hot water usage: Large families that use a lot of hot water will find a regular boiler more efficient. A home with fewer occupants will benefit from a combi boiler.
- Home size: Because combi boilers don’t require hot water cylinders, we can install in a home with less space.
- Solar water heating compatibility: If you’re using solar water heating, it’s important to know that many combi boilers are less compatible and inefficient with this heating system.
Many old gas regular boilers and oil models are just boilers with hot water cylinders to live in the airing cupboard and cold water tanks to live in the loft.
When replacing regular boilers or system boilers, you may be able to keep the hot water cylinder to go with your new boiler installation.
Combi boilers are the most popular in the UK, combi boilers, also known as combination boilers are a 1 unit system which lives in a kitchen cupboard.
Combi boilers are brilliant unless you require a high demand for water at once to multiple taps. In this case, you would be better with a regular boiler.
Here is some information about the different boiler systems available:
Boiler Replacement – Heat only boilers
Heat-only boilers also known as conventional systems or regular boilers.
These models store hot water in a cylinder and cold water in a storage tank.
A regular boiler produces hot water more efficiently than combi boilers and can supply multiple taps at once with water.
The circulation pump is housed as an external component, along with feed and expansion tanks.
These typically feature an on and off switch. This means you can heat the water in the storage tank when you know you’ll be using it. You’ll conserve energy when it’s not in use.
- Conventional boilers work well with large households.
- Large amounts of hot water can supply multiple taps at once.
- Replacing a conventional boiler with a combi can be a complicated process.
Boiler Replacement – Combi Boilers
Combination boilers, also known as combi boilers, are the most popular type of home boiler systems registered in England.
They provide a combination of instant hot water and efficient central heating.
When you request heated water, a sensor signals the boiler to burn fuel, either gas, electric, or oil.
- Gas combi boilers don’t require any external components, making it appear sleek and compact.
- Hot water is available on demand without the use of cold water or a feed and expansion tank.
- They are more affordable to install than regular models.
- More internal moving parts means there are more potential malfunctions. These issues may be more expensive to fix than with a conventional boiler.
- Hot water from a combi boiler system can only support one user at a time. This makes combi boilers less ideal in a larger home.
Boiler Replacement – System Boilers
System boilers are known as closed vent boilers.
These are perfect if you prefer a heat-only boiler but would like less external components.
Like a combi boiler, these models have their external components built into the body of the heating system.
System boilers contain a hot water cylinder, but the feed and expansion tanks are supplemented with an expansion vessel located in the new boiler.
This is where the circulation pump and the valves are housed.
- System boilers work well with large homes where heated water is needed for more than one task at a time.
- They don’t require the space needed for a conventional new boiler.
- System boilers are very efficient in areas with low water pressure.
- They require space for the heated water cylinder.
- Installation costs are higher than with basic combi systems.
- They are less efficient than combi systems since they lose heat from stored water in the hot water cylinder.
- One has to wait for it to heat up again after heated water has emptied from the cylinder.

What will replace gas boilers in 2025?
According to the Committee on Climate Change, approximately 14% of greenhouse gas emissions are emitted from our homes.
The primary source is from gas heating systems. Because of this statistic, it has been decided that after 2025, no new homes will be using the gas grid.
Eventually, we will replace with low-carbon energy options with high energy efficiency.
Many homeowners are wondering what these replacement options will look like.
Here are some of the many upcoming heating alternatives for an energy-conscious home:
Heat pumps are one of the more commonly known replacements to gas heating systems.
Using a refrigerant, heat pumps absorb the natural heat that is found in the ground, water, or air. The refrigerant is compressed to increase the temperature, which is then used to warm the cold water.
When the water is heated, it is then pumped to your radiator and water taps.
Unlike a traditional boiler, heat pumps don’t need any gas or oil to run. Instead, they work by only using electricity and other natural, renewable energy sources. This results in no additional carbon emissions.
There are many advantages to using a heat pump.
A heat pump is more durable than a gas model. Some even offer cooling capabilities during the summer months in addition to the heat they provide in winter.
An electric model works very similarly to a gas one. Instead of gas, it uses electricity to heat the water.
These are usually more compact than gas versions, whilst remaining just as efficient.
Like heat pumps, an electric model can’t be 100% CO2 neutral if it uses electricity produced from burning fossil fuels.
Options like using solar panels or other forms of renewable energy are available to reduce your electric boiler’s carbon footprint.
Solar heating systems
Solar (thermal) heating systems reduce fossil fuel usage considerably, even though they don’t eliminate the use of gas.
Unlike electric, solar panels, thermal heating systems use heat from the sun to warm up your household water.
Using solar panels on the roof of your home, heat is absorbed and transferred to a tank similar to conventional boiler systems.
