30kW Boilers – Everything You Need to Know
So you’ve done your research and know that you need a 30kW boiler for your home. However, there are still a few other factors to consider, such as which type of boiler you want and what kind of fuel you want to use.
There are a variety of different types of boilers out there, all of which also have a range of high-quality models to choose from. Therefore, it’s important to get an overview of your options and compare them – in this article we’ll help you with just that.
30kW System Boilers
There’s a lot to know about system boilers but essentially it is a type of boiler that works in conjunction with a separate cylinder for storing water.
System boilers come in a range of sizes including 30kW. Generally, they’re best suited for larger homes that have a higher demand for heating and hot water. A 30kW boiler tends to be best suited for homes with approximately 20 radiators.
Below we’ve mentioned some of the best system boiler 30kW options to give you an idea of what’s available.

As you can see, there are plenty of viable options to choose from when it comes to 30kW system boilers. However, what may make or break which model you choose are the installation costs. Installation costs can vary vastly depending on the specific installation company’s rates and whether or not you’re having a like-for-like boiler replacement.
That’s why it’s important to compare quotes to make sure you get the best price possible. To do this, you normally can call local installers one-by-one and repeatedly explain what you’re looking for. But this can take a lot of your valuable time. Luckily, GreenMatch has a much faster way to do this.

30kW Combi Boilers
First thing’s first – what is a combi boiler? Basically, it is a compact boiler unit that doesn’t require extra components such as a hot water cylinder. It provides hot water on demand and is the most popular type of boiler in the UK.
Combi boilers generally come in smaller output sizes. However, there are some more powerful combi boilers with 30kW available. A 30kW combi boiler is usually recommended for homes with up to 15 radiators.
What is the best combi boiler available in 30kW, then? We’ve listed some of the UK’s favourites below to help make your decision-making easier.

30kW Heat-Only Boilers
A heat-only boiler, also commonly known as a conventional or regular boiler, is the UK’s traditional boiler heating system. Features of a heat-only boiler include having a water tank in your loft and a hot water cylinder in an airing cupboard.
There are various pros and cons of a conventional boiler, such as being able to meet high hot water demands but at the cost of taking up a lot of space in your home. If you feel like this type of boiler is the right choice for your home, then you can check out a selection of the top conventional boilers below:
1. Baxi 830 Heat 30kW regular gas boiler
We already mentioned the combi version of this boiler above. Due to its popularity, it’s also available as a conventional boiler. If you have up to 15 radiators in your home then the combi 30kW boiler is likely more suitable for you. Whereas if you have around 20 radiators then this 30kW conventional boiler might be a better fit.
- Central Heating Max. Output: 30kW
- LPG compatible: No
- Efficiency: 93%
- Band rating: A-rating
- Warranty: 10 years
- Estimated price (excl. installation): £944
2. Vaillant ecoFIT Pure 430 (30kW) regular gas boiler
Another great Vaillant 30kW boiler option is the ecoFIT Pure 430 conventional boiler. This particular model is also available in 4 smaller sizes (12.3kW, 15.2kW, 18.3kW and 25.4kW) and 1 larger size (34.8kW). So, if you’re having second thoughts about whether a 30kW is right for your home, with this range you’re still likely to find a size that works for you.
- Central Heating Max. Output: 30.5kW

This is another boiler from Ideal’s Logic flagship range. The 30kW boiler is the most powerful boiler in the Logic Heat Max range. If you’re not 100% sure whether the 30kW boiler is right for your home, you can also go one size down with the 24kW boiler.

- LPG compatible: Yes
- Efficiency: 93%
- Band rating: A-rating
- Warranty: 10 years
- Estimated price (excl. installation): £1,117
It’s important to note that conventional boilers are generally only recommended in the case of like-for-like boiler replacements (updating an old conventional boiler with a newer model). Since this boiler type requires additional parts installed throughout the house, it can be especially disruptive and costly if you’re changing from a combi or system boiler.
30kW Electric Boilers
Electric boilers can be a great option when used in conjunction with solar pv panels. However, unfortunately, 30kW electric boiler options and other larger output sizes are not common. In general, electric boilers are more suitable for smaller homes that require smaller output sizes. For example, if you live in a house with 10 radiators then it may be worth considering a 15kW electric combi boiler.
30kW Biomass Boilers
Biomass boilers can be a great option for those who live in rural areas and want a potentially low-carbon heating option. This boiler type is one of the best boilers for 5 bedroom houses as they require a lot of space for both the boiler itself and storing the fuel.
There are a few manufacturers in the UK which offer 30kW biomass boilers, such as Froling and Grant. So, you have enough options to choose from. However, when it comes to biomass boilers you will also need to make other decisions, such as which type of biomass fuel works best for you. On top of that, there are also restrictions on biomass boilers depending on where you live in the UK.
This is why it’s always important to seek advice from a professional heating engineer to help you figure out which type of biomass boiler best fits your needs and circumstances. At GreenMatch, we can provide you with free quotes from up to 4 local boiler installers so that you can objectively compare and choose the best deals. Simply click the button below to get started.
