Terraced propertyBoiler Installation in the South East: Common Challenges & Solutions
Hard Water Protection Is Essential
The Context: The South East has some of the hardest water in the UK, particularly across Kent, Surrey and Berkshire. Limescale build-up can damage boiler heat exchangers, reduce efficiency, and shorten your boiler's lifespan.
The Solution: Every WarmZilla installation includes a magnetic system filter to safeguard your warranty.
Combi vs System Boilers
The Context: Choosing the right boiler type ensures optimal performance and lower energy bills. Combi boilers are ideal for most 2–4 bedroom homes with good mains pressure in the region.
Our Advice: System boilers suit larger properties. We recommend based on your home’s actual suitability.
