Brand Heritage and Market Position
When comparing two heavyweight brands like Main and Intergas, their impressive histories tell quite different stories.
Main got its start back in 1874 in Milwaukee, while Intergas kicked off operations in 1939 in the Netherlands.
You'll find Main has grown into a global powerhouse, with over 16,000 employees across 37 countries.
They've built a rock-solid reputation in both residential and commercial heating solutions.
Intergas might be the younger sibling, but they're no slouch.
They've dominated the Dutch market and are steadily gaining ground in the UK.
Their claim to fame? They revolutionised the industry with their two-in-one heat exchanger in 1996.
Both brands pack serious market punch today.
Main's part of a global market valued at £4.34 billion in 2023, while Intergas caught the attention of heating giant Rheem, who acquired them in 2019.

Available Product Lines
Both brands pack impressive performance ratings, but let's look at what they actually offer on the shelves.
Main's Eco Elite series keeps things straightforward with two product lines: combi boilers in 25kW and 30kW outputs, and system boilers at 24kW and 28kW. You'll also find water heaters and cylinders if that's what you need.
Intergas brings more variety to the table with their extensive range. Their lineup includes the popular Combi Compact HRE, the eco-friendly ECO RF, and the premium Xclusive series. They've got system and regular boilers too, with outputs from 12kW all the way up to 40kW.
| Feature | Main | Intergas |

| Combi Range | 25-30kW | 24-40kW |
| System Range | 24-28kW | 18-40kW |

Warranty Coverage and After-Sales Service
Peace of mind comes down to solid warranty coverage and reliable after-sales support. When comparing Main and Intergas, you'll find some notable differences in what they offer.
Main provides relatively standard warranty periods of 3-5 years, though you can extend this through their Baxi Works installer programme. They'll cover parts and repairs within 30 days of manufacture, and their after-sales service includes maintenance plans starting at £24.99 monthly.
Intergas really shines in the warranty department. Their premium Eco RF and Xclusive ranges come with impressive 10-year warranties, while the Xtreme and HRE models offer 7 years of coverage.
Even their basic Rapid boiler includes a 3-year warranty.
Both brands require annual servicing by Gas Safe registered engineers to keep your warranty valid. They also offer fixed-price repairs for out-of-warranty units and guarantee any replaced parts for one year.
Installation Requirements and Flexibility
When it comes to installing a new boiler, you'll want to carefully consider the space requirements and system flexibility of different brands. Both Main and Intergas offer practical solutions for tight spaces, but there are some key differences to note.
Main boilers need just 5mm clearance on the sides and 200mm on top, while Intergas requires 5cm above for front panel removal. If you're planning to tuck your boiler into a kitchen cupboard (a popular choice!), both brands will work fine with proper ventilation.
The connection options are quite flexible too. Main uses 22mm male connections for central heating, while Intergas offers both 22mm for CH and 15mm for hot water.
You'll find that both brands give you choices for flue positioning – whether through the roof or wall.
What's particularly handy about Intergas is its 30° arc on components, making it easier to access parts in cramped spaces. This can be a real lifesaver during maintenance!
Smart Technology Features
Modern smart technology has revolutionised how we interact with our boilers, and you'll find impressive features in both Main and Intergas models.
Both brands let you control your heating from your smartphone, so you can warm up your home before getting out of bed on those chilly mornings.
Intergas takes the lead with its proprietary ComfortTouch thermostat and Service Dashboard, which allows installers to monitor your boiler's performance remotely.
They've also integrated voice control through Alexa and Google Assistant, so you can adjust your heating with a simple command.
Main isn't far behind, offering compatibility with popular smart thermostats like Nest and Hive.
Their models include weather compensation technology that adjusts your heating based on outdoor temperatures – pretty clever, right?
Both brands support OpenTherm technology for smarter communication between your boiler and thermostat, helping you save energy and money while maintaining ideal comfort levels.
Environmental Credentials
Today's environmentally conscious homeowners will find Intergas leading the pack with impressive green credentials. With efficiency ratings up to 95.8% for household hot water and high-performing eco modes, you'll slash both your energy bills and carbon footprint.
When it comes to materials and recycling, Intergas really shines. Their boilers are 90% recyclable, and they've kept plastic usage to a minimum – just three components in total.
That's quite a difference from many manufacturers who seem to think plastic is the answer to everything!
While we couldn't find specific environmental data for Main boilers, Intergas is actively pushing the sustainability envelope. They're part of Rheem's "A Greater Degree of Good" initiative, focusing on eco-friendly design, manufacturing, and delivery methods.
If you're looking to make your home greener, Intergas's commitment to reducing environmental impact makes them a solid choice.

Cost Analysis and Value for Money
Beyond environmental benefits, the pounds and pence of a new boiler matter to every homeowner.
When comparing Main and Intergas, you'll find some interesting cost trade-offs that might affect your wallet both now and later.
If you're looking at upfront costs, Main boilers are generally the more budget-friendly choice, with their combi models ranging from £620 to £710.
Intergas units start higher at £625 and can reach £1,210 – quite a jump if you're watching your pennies.
But here's where it gets interesting: Intergas boilers might save you more in the long run.
With efficiency ratings up to 95.8% compared to Main's 93%, you could see lower energy bills over time.
Plus, Intergas offers longer warranties (up to 10 years versus Main's 5 years) and has fewer moving parts, potentially reducing repair costs.
Your choice might depend on whether you want to save now or later – it's a bit like choosing between a budget airline ticket and a premium one with extra perks.

Customer Reviews and Satisfaction
Sorting through customer feedback reveals quite a gap between these two brands.
While Main has a documented 67% satisfaction rate (below the industry average of 82%), Intergas's customer satisfaction data is harder to pin down – it's like trying to find a plumber on New Year's Eve!
Main's 2-star customer score might raise some eyebrows, but it's worth noting that installers often praise the Eco Compact range for its reliability and build quality.
They've even dubbed it a "hidden gem" in the industry, particularly popular with landlords.
When it comes to Intergas, while direct customer reviews are scarce, the brand earns positive marks from heating engineers who appreciate its innovative condensing technology.
Plus, their confidence shows in their warranty – offering up to 10 years compared to Main's 5-year coverage.
If you're big on customer reviews, Main's documented feedback gives you something concrete to work with, even if it's not all glowing.
