Frequently Asked Questions
Is the 10-year warranty better than the Reliable tier's 7-year warranty? Yes — it covers you for three additional years, meaning more protection against the cost of any manufacturer-related faults over the boiler's lifetime.
What does the system filter actually do? A system filter removes debris, rust, and sludge that builds up in your heating system over time, protecting your new boiler from damage and helping it run efficiently for longer. It's included as standard with this tier.
Is Premium worth the extra cost compared to Reliable? If you want the longest warranty available and smart heating controls, yes — the extra cost reflects genuinely different included features, not just a mark-up. If those aren't priorities for you, our Reliable tier is a strong, more cost-effective option — see our Reliable Boiler Installations page.
