The boiler's high efficiency rating of 89.6% means you'll save on energy bills while keeping your home cosy.
Keston S30 System Boiler Performance and Efficiency
Packing an impressive 30kW of power output, Keston's S30 system boiler delivers reliable heating performance that'll keep your whole home cosy without breaking the bank. The boiler achieves an excellent SAP seasonal efficiency rating of 89.6%, earning it an ErP A-rating for heat.
| Feature | Specification |
|---|---|
| Power Range | 6.1-30.3kW at 70°C |
| Efficiency Rating | 89.6% SAP |
| Gas Consumption | 0.622-3.135m³/hr |

Keston S30 System Boiler Pros and Cons
While impressive performance specs are valuable, understanding both strengths and limitations helps you make a well-rounded decision about the Keston S30.
On the plus side, you'll love the flexibility of the twin flue system that can stretch up to 27m, perfect if you're dealing with tricky installation spots. The compact size means it'll tuck nicely into a kitchen cupboard, and the 7-year warranty offers solid peace of mind.
However, there are some trade-offs to evaluate. The 30kW output might leave you wanting more if you've got a larger home, and you'll need space for a separate hot water cylinder.
The price tag is also a bit steeper than some competitors, and you won't find the widest range of models in Keston's lineup.
How Does The Keston S30 System Boiler Compare To Similar Models From Other Manufacturers?
When comparing the Keston S30 against its major competitors, you'll find some interesting differences worth noting.
While the S30 matches its rivals with a 30kW output, it falls slightly behind in efficiency at 89.5% compared to the 94% offered by Worcester Bosch, Vaillant, and Ideal models.
The S30's 7-year warranty is decent but doesn't quite match the 10-year coverage you'll get from the competition.
Price-wise, you're looking at similar costs to the Ideal Logic+, though Worcester Bosch and Vaillant tend to command higher prices.
The S30's unique twin flue system might be your saving grace if you're dealing with tricky installation requirements.
However, when it comes to overall reputation and reliability, Worcester Bosch and Vaillant have stronger track records in customer satisfaction.
How Much Does A Keston S30 System Boiler Cost?
Looking to budget for a Keston S30 system boiler? You'll typically pay around £1,100 (including VAT) for the unit itself, though prices can range from £1,094.79 to £1,400 depending on your supplier and when you purchase.
Don't forget to factor in the installation costs, which usually run between £500-£1,000.
You'll also need to budget about £300 for essential extras like the magnetic filter and flue system.
All in, you're looking at a total investment of £1,900-£2,400.
It's worth noting that the S30 sits at a slightly higher price point than some competitors – about £250-£400 more than the Worcester Bosch 4000 (30kW).
However, with its 89.5% efficiency rating and 5-7 year warranty options, it could save you money in the long run.
Keston S30 System Boiler Warranty and Service Support
The Keston S30 system boiler comes with solid warranty protection for your investment.
You'll get a standard 5-year parts and labour warranty, which extends to 7 years when you install it with a Keston System Filter. Just remember to register within 30 days of installation to activate your coverage.
You'll need to schedule annual service to keep your warranty valid, but that's actually a good thing for your boiler's health.
If you ever need help, Keston's helpline is available seven days a week, with extended hours on weekdays.
The warranty covers mechanical and electrical breakdowns, but there are some exclusions.
Issues from scale build-up or incorrect installation aren't covered, and you'll need proof that a Gas Safe registered engineer installed your boiler.
Final Verdict
After carefully weighing all the evidence, you'll find the Keston S30 system boiler delivers solid performance for medium-sized homes.
With its 89.5% efficiency rating and 30kW output, it'll keep your house cosy while helping manage those energy bills.
The compact design and flexible twin flue system make it a practical choice for most installations, even in those tight kitchen cupboards.
You'll appreciate the user-friendly controls and clear display when you're checking up on your heating system.
While the £1,900-£2,400 price tag isn't the cheapest around, you're getting decent value with the 7-year warranty and modern features.
Just keep in mind that customer reviews are mixed on reliability.
