The other practical difference is capacity and recovery. Because an unvented cylinder is sealed and pressurised, it can be built with an immersion element, a coil, or both, and sized to match a property's actual hot water demand rather than what a loft tank happened to allow. That flexibility is a big part of why unvented systems are now specified so widely in new-build and refurbishment work.
Plumb2U carries water softeners and the resin, salt and spare parts to keep them running, at trade prices with next-day despatch across the UK, whether the job is a first softener install or a service call on an existing one, for trade buyers from Epsom to anywhere else in the country.
Length matters just as much, and not only for reach. A flexi flexible hose supplier that is too long for the gap it is bridging tends to kink or sit under unnecessary strain, both of which shorten its working life. Too short, and it is either fitted under tension or simply does not reach, forcing a compromise on the install that causes problems later. The right length sits with a gentle curve, not a tight bend, and not stretched taut.
For anyone new to the category, the parts worth understanding are the resin tank itself, the brine tank that holds the salt, and the control valve that manages the whole cycle, timing when regeneration happens and how much water and salt it uses. Cheaper units tend to run on a fixed timer regardless of actual usage; better-specified ones meter flow and regenerate only when the resin genuinely needs it, which uses less salt and less water over a year.
Cost is the other real variable. Braided hoses cost more than rubber equivalents, and for buyers working through volume on multiple jobs, that difference adds up over a year of trade supplies. The right call is matching hose type to the duty and visibility of the specific connection, rather than defaulting to one type across every job regardless of application.
Neither option is a universal upgrade over the other; each solves a different starting condition, and the right call is decided by the pipework already in the property, not by brand preference.
