Plumbright Southern carries out hot water cylinder replacement in Hedge End. If your cylinder is leaking, slow to heat or running out too fast, we remove it and fit a new one sized for your home.
Look for water around the base, rust or green marks on the copper, or hot water that runs out quicker than it used to. A cylinder that takes much longer to heat up is another clue. Once the inside starts to corrode, repairs rarely last, and a replacement is the safer choice.
More Information
A vented cylinder is fed by a cold water tank in the loft, so pressure depends on gravity. An unvented cylinder runs straight off the mains, which gives stronger showers but needs safety valves and a yearly check. We explain which suits your home and your water pressure.
Much of south Hampshire has hard water. Over time, limescale builds up on the heating coil and immersion heater inside a cylinder, which slows heating and wastes energy. When we fit a new cylinder, we can talk you through ways to cut down on scale, such as a scale reducer on the incoming supply.
Most hot water cylinders last around 10 to 15 years, though some go on longer. Age alone is not a reason to replace one. Leaks, rust, slow heating or a failed coil are the usual signs. If yours is showing any of these, we can take a look and give you an honest view.
A like for like cylinder swap is usually done in a day. Changing from a vented to an unvented cylinder takes longer, as it involves new pipework, safety valves and a discharge pipe. We will tell you how long your Hedge End job should take once we have seen the setup.
Yes, but only for part of the day while the old cylinder is drained and the new one is fitted. Your cold water can usually be turned back on sooner. We plan the work so that, in most cases, you have hot water again by the end of the job.
Plumbright Southern has replaced hot water cylinders in Hedge End for 25 years, from old copper tanks in airing cupboards to modern unvented models. Swapping a cylinder means draining down, disconnecting the old one, fitting the new cylinder and controls, then refilling and testing. Our engineers are Gas Safe registered too, so we can check the boiler that heats the cylinder at the same time.
