Why coastal installs need coastal-spec components
It's not a marketing line. A standard external condensate pipe, painted-mild-steel flue terminal and plastic isolation valve on a coastal property in Hartlepool will start to fail in 2–4 years. Stainless flue terminals, frost-protected and insulated condensate runs, and brass isolation valves cost very little extra at install and add a decade to the life of the install. We don't quote it as an upgrade — it's our default Hartlepool spec.
