Older Terraces: Often require careful system compatibility checks, pipework upgrades, and precise flue routing to accommodate modern combi or system boilers.
1930s & Larger Homes: Typically feature extensive radiator circuits and higher heating demands that require robust boiler capacity and proper system balancing.
Limescale Protection: Combating local hard water scale build-up that can reduce boiler efficiency, damage heat exchangers, and shorten component lifespan.
