Keston Heat 2 45 Heat Only Boiler Pros and Cons
Making sense of any boiler's strengths and limitations helps you decide if it's the right fit for your home, so let's break down what the Keston Heat 2 45 brings to the table.
On the plus side, you'll appreciate its impressive 93% efficiency rating and flexible twin flue system that extends up to 18m. The built-in weather compensator and pump help optimise performance, while the 5-year warranty (extendable to 7 years) offers peace of mind.
However, there are some drawbacks to take into account. It's pricier upfront compared to similar models, and you'll need a professional installation due to its complexity.
Since it's a heat-only boiler, you'll also need space for both a hot water cylinder and cold water tank. Plus, you're limited to heating without cooling options.
How Does The Keston Heat 2 45 Heat Only Boiler Compare To Similar Models From Other Manufacturers?
Direct comparisons against similar 45kW heat-only boilers reveal how the Keston Heat 2 45 stacks up in today's competitive market.
When matched against the premium Viessmann Vitodens 200-W 45kW, you'll notice the Keston falls slightly short on efficiency (96% vs 98%) and warranty coverage (7 years vs 10 years).
However, it'll be gentler on your wallet.
The Baxi 800 Heat 45kW and Ideal Logic Max Heat 45kW offer similar efficiency ratings to the Keston but come with longer 10-year warranties.
They're also typically more affordable, making them compelling alternatives.
What sets the Keston apart is its unique 50mm muPVC flue system and built-in serviceable flue Non-Return Valve.
These features make it particularly valuable for tricky installations where standard flue options won't cut it.

All in, you're looking at a total cost between £3,025 and £3,525.
