Ravenheat CS90 Combi Boiler Pros and Cons
Savvy homeowners weighing their boiler options will find plenty to like about the Ravenheat CS90, though it's not without its drawbacks.
You'll appreciate the compact, lightweight design that won't hog your wall space, along with its impressive 90.3% efficiency rating. The built-in automatic bypass and large digital display make operation a breeze, while the integral valve kit saves you money on extra parts.
However, you'll want to take into account some limitations. The 2-year warranty falls short compared to other brands, and if you've got a busy household with high hot water demands, this mightn't be your best bet.
You'll also need to budget for a separate programmer since one isn't built in.
The good news? Installation's straightforward thanks to those handy removable side panels and flexible condensate pipe.
How Does The Ravenheat CS90 Combi Boiler Compare To Similar Models From Other Manufacturers?
When comparing the Ravenheat CS90 to its competitors, you'll find it sits comfortably in the middle of the pack for most key features.
Its A-rated efficiency matches industry standards, while its 12 litres/min flow rate is decent but falls short of premium models like the Vaillant ecoTEC plus.
The CS90's price point of £1,393 – £1,893 makes it more affordable than Worcester Bosch but pricier than budget-friendly Alpha models.
However, its 2-year warranty is especially shorter than many competitors who offer 5-10 years of coverage.
Where the CS90 shines is in its compact dimensions and straightforward installation.
While it mightn't have the advanced features of German-engineered Viessmann or the smart controls of newer Bosch models, it's a reliable workhorse that'll get the job done without breaking the bank.

How Much Does A Ravenheat CS90 Combi Boiler Cost?
So you're looking to purchase a Ravenheat CS90 combi boiler? Let's break down the costs you can expect.
The CS90 30kW unit itself typically costs £593 including VAT, with prices ranging from £525 to £700 depending on where you buy it.
But that's just the beginning of your investment.
You'll need to factor in installation costs, which usually run between £500 and £1,000, plus about £300 for essentials like the filter and flue.
All in, you're looking at a total cost between £1,393 and £1,893 for a complete installation.
Word to the wise: if someone quotes you under £1,000 for the full installation, that's a red flag.
While the CS90 is one of the more affordable options in Ravenheat's range, it's worth investing in proper installation by a qualified engineer.
Ravenheat CS90 Combi Boiler Warranty and Service Support
Protection for your investment comes in the form of Ravenheat's 2-year warranty on the CS90 Combi Gas Boiler.

You'll also need to keep up with annual servicing by a qualified technician to maintain coverage.
While the CS90's 2-year warranty might seem modest compared to other Ravenheat models offering up to 10 years of coverage, you'll still get solid service support.
The company provides next-day delivery on 95% of spare parts and offers extensive online resources for troubleshooting common issues.

At £593-£605 for the unit itself, plus installation costs between £1,393-£1,893, it's one of the more affordable options in its class.
