Why change your boiler?
Reasons to replace or upgrade your heating system can vary. Your existing boiler may be faulty or not effective enough for your household. If you need hot water and radiators on regularly, it may be worth checking if your boiler can cope. A performance that’s too low makes the house less comfortable. And putting too much pressure on an inadequate system can lead to damage and costly repairs.
Generally, there are two common reasons why UK homeowners start boiler projects:
- Because replacing an old boiler is more cost-effective than repairing all its problems
- Or the property simply needs a better heating system to deal with a busy household and fluctuating temperatures
Types of boilers

The next decision you should make before browsing Ideal boiler costs and models is the type of heating system you need. There are three popular systems to choose from, each best suited for particular household habits and building structures. Unless you already know everything about them, here’s a helpful breakdown of the difference between combi, system and heat-only boilers.
Combi boilers
As the most popular design on the home heating market at the moment, it’s likely that you already have this system. Compact and practical, a combi boiler draws water directly from the mains and contains the heater and central heating boiler in one.
The best combi boilers around – Ideal, Worchester, Viessman – go the extra mile and create sleek, high-tech systems for maximum appeal and efficiency. But there are downsides you should be aware of.
Advantages
- Compact system that can fit in a corner or cabinet
- Doesn’t need a cylinder or water tank
- Mains pressure distributes water faster throughout the house
- Often simpler and cheaper to install than other more complicated systems
- Typically includes smart features for better heating control – analogue configuration is also available
- Easier to maintain and repair
- Efficient prevention of sludge build-up
Disadvantages
- Can only send hot water to one outlet at a time
- So, not the best choice for a large household that may need to use multiple taps or showers simultaneously
- Can’t have a combi boiler and a power shower
- Performance and suitability depend on the mains’ pressure and condition
- Old pipework may need replacing to cope with the new system
System boilers
Key similarities between a combi and system boiler: both get water directly from the mains and can come in very sleek, efficient designs. From there, the latter option deviates into its own strengths and weaknesses. It’s definitely worth considering for a large property and household, but you need to make sure you have the space for it. Let’s go into a bit more detail.
Advantages
- Can cover high hot water demand, supplying multiple outlets at the same time
- Installation is easier than heat-only boilers because of the compact design of the unit minus the cylinder
- Decent water pressure from the mains
- Fewer required tanks mean a system boiler doesn’t take up too much space
- Compatible with solar thermal configuration
Disadvantages
- The cylinder takes up room
- Hot water can run out
- And takes time for the system to heat up more water
- The cylinder needs good insulation to regulate temperatures
- Without insulation, heating bills are difficult to manage
- Problems with the mains affect the boiler’s performance
Heat-only boilers
This is the oldest system available, but not the first choice for homeowners. The amount of room its two tanks take up – one for hot water and one for cold – is the main reason why. This sometimes leaves limited living space to enjoy. But this is more or less the only downside. So, if you do have the right place for it and like the sound of a conventional system’s benefits, you should explore what providers have on offer.
Advantages
- Can be cheaper overall
- Covers multiple water outlets
- Straightforward system to install
- Uses stored water, so problems with mains affect the heating system less than other designs
Disadvantages
- Not the best water pressure
- Needs room for the two tanks, typically fitted in the loft
- Installation can take time because of different and awkward components
- Insulation may be necessary to cut down on heating bills
Are Ideal boilers any good?
The truth is there are many good brands out there that can provide the hardware and services you need. And, yes, Ideal is among them for several good reasons. The company is famous for producing a wide range of models for every kind of household. So, if you’re wondering what makes Ideal Logic a good boiler, keep reading for a summary of the popular brand’s ins and outs, from models and benefits to prices.
Awards
The first thing to note is that Ideal has won a lot of awards for its innovative and performance-boosting boilers. In addition to Product of the Year a few years back, the brand’s Logic and Logic+ ranges boast a number of Queens Awards for Enterprise. These alongside their Vogue boilers have each also earned a Good Housekeeping status over the years.

- Decent innovation and customer service
- Good warranties that cover boilers for several years after they’re installed
Ideal boiler disadvantages
- To keep costs low, some boilers are of lesser quality – expect reliability issues

- Customer service and energy efficiency are not always up to par
Boiler ranges
Now that you know more or less what to expect from this brand, you can figure out which models offer the best value for money.

They’re the next step up in this range with better features and multiple awards. If you want cost-effective efficiency, definitely include Logic units in your research.

Combination boilers
Logic Combi
Combination boilers are Ideal’s strength, so you’ll find a good variety of options. Something vital to keep in mind is the size of your property. Each range typically comes in a number of models to cover different output demands. This particular option has three of increasing price and performance with a two-year labour and parts warranty if your register within 30 days of installing the system.

Logic Max Combi
The key perks of this model are LPG compatibility, superior smart controls and an Ideal System filter. This boosts the boiler’s ability to flush out impurities. If you’re sure you want a combi boiler, this is one of the highest performing options on the market. You’ll probably find Viessman models that surpass it, but when it comes to getting good heating in a small house and with a limited budget a Logic Max unit is a decent choice.

Alongside frost protection and a smooth, compact look, you can add LPG conversion to a C30 or 35 system and a flue configuration of your choice. The warranty for this range is seven years.

System boilers
Logic+ System
This range features the exact same luxuries as combi boilers, but with a system configuration and Quiet Mark accreditation. This is on top of the other Logic+ awards. Installing it can be more complicated because of the cylinder and piping required. But the Ideal boiler cost can actually be lower than combination units.
Take a look at what the Logic+ System models have to offer and decide for yourself whether any of them are worthwhile. There are two warranties to keep in mind. Parts and labour are covered for seven years, while the heat exchanger is for ten.

But the warranty will cover parts and labour for a good seven years.

How much is an ideal boiler in [phpmu snippet=3]?
The price of the boiler itself takes up a large part of a project’s budget. But there’s more to it than that. Unless you’re an engineer yourself, you’ll need a professional to install the system. And an Ideal boiler service cost can vary depending on the extent of work required. For example, are you replacing, upgrading or relocating the boiler? Each direction affects how the final bill will add up.
What to budget for
Let’s be more specific about what goes into an Ideal boiler installation cost. You may need to save up for a number of different tasks. So go through our handy checklist as you think about your project’s needs. Then you can research exactly what these demands are worth.
- Boiler – your choice of brand, model and system determines the cost
- Installation – a replacement, upgrade, relocation or whole conversion affects the overall cost
- Labour – the professional’s quote should include standard work, but anything extra, like special features or alterations, will boost your budget
- Extra fees – in addition to labour, factors like overtime, travel, waste disposal and other costs can pile up
Ideal boiler costs
Type of residential service | Approx. cost |
Combi boiler | £600 – £1,000+ per unit |
System boiler | £800 – £1,000+ per unit |
Heat-only boiler | £700 – £2,500+ per unit |

How to manage Ideal boiler expenses

Carefully planning and overseeing your project is a good step in managing your expenses. But there’s even more you can do to help with the process. If you’re happy to keep researching, here are three key areas you’ll find very useful. They expand your understanding of Ideal boilers, home improvement projects and how to save up for it all.
Set a realistic budget
Get to know your home and what heating system suits it best. Make a note of the issues you have in your area, like temperatures and the condition of water mains. These will help you create a checklist of the exact features you need to stay comfortable in your house. Then narrow down your boiler options to those that match your demands. This is how you work out if the cost of Ideal logic combi boilers is worthwhile.
Learn the features and benefits of Ideal boilers
You can turn yourself into an Ideal boiler specialist. The brand provides detailed PDF guides for most of its models. So there’s plenty of information to explore in your search for the best possible boiler. Want to know the dimensions of the different flues available? What does l2 mean on an Ideal boiler? What’s the layout of the condensing system? All the answers are literally at your fingertips. Even minor details like these can help you make a good investment.
Financial assistance
Keep in mind that Ideal offers a monthly payment scheme to help manage your expenses. Otherwise, you may be eligible for a boiler grant. If you’re a low-income household and your boiler is over ten years old, there’s a good chance you’ll get a new unit for free. If not, your home insurance provider may be able to help with your finances. Keep in mind, though, that services like British Gas HomeCare will only cover your Ideal boiler cost when the existing unit is faulty or damaged. Despite the various conditions, there’s plenty of support for UK homeowners.
Conclusion
This is a lot of information to take in, but Ideal boilers should be easier to understand now. Even though the brand is perfect for low-cost efficiency, you can spend a bit extra and get a high-tech system. Browse through your options and decide what feels right for your property and pocket. Also researching all you can about designs and professionals makes it easier to plan a successful project.
