Time for a new cylinder?
Signs a repair won’t cut it any more
When a cylinder is past saving, the symptoms are clear. These are the signs we see before recommending a replacement across Manchester.
No hot water in the apartment
Nothing coming through hot at any tap. Often a tripped immersion, failed heater element or a control fault ‑ we’ll find it fast.
Hot water only getting lukewarm
Water heats but never gets properly hot, or runs out fast. Usually a thermostat, element or blending-valve issue.
Faulty immersion heater
The immersion won’t heat, keeps tripping the electrics or has burnt out. We replace immersion heaters and elements.
Faulty thermostat
Water too hot, too cold or wildly inconsistent. A failed cylinder thermostat is one of the most common causes.
Blending / mixing valve issues
A seized or failed blending valve can leave you with scalding or lukewarm water. We test, adjust and replace them.
Expansion vessel problems
Dripping, banging pipes or discharging water often points to a failed expansion vessel. We recharge or replace them.
Pressure relief valve issues
Water discharging outside or from the tundish usually means a PRV or expansion fault. We diagnose it safely.
Tundish dripping
That little clear fitting dripping or overflowing is a warning sign ‑ we’ll find why it’s discharging and put it right.
Cylinder making noise
Banging, rumbling or hissing from the cylinder or pipes. Often limescale, expansion or valve related ‑ and fixable.
Hot water cylinder leaking
Water pooling around the cylinder or in the cupboard below. We identify the source and advise repair or replacement.
High-rise & apartment systems
Pressure, flow and shared-system quirks in flats and towers. We work in city centre developments every week.
Emergency hot water
No hot water and can’t wait? We offer emergency hot water repairs across Manchester where possible ‑ just call.

Unvented cylinder replacements in Manchester
Hot water cylinders don’t last forever. After years of heating hard Manchester water, an unvented cylinder can corrode, scale up, spring a leak, or simply stop holding heat the way it used to. At that point, pouring money into repairs is often a false economy ‑ a new, correctly sized cylinder is more reliable, more efficient, and fixes the problem for good. HotFix supplies and fits electric and unvented cylinders across Manchester apartments, and we’ll always give you honest advice on whether it’s genuinely time to replace.
Signs your cylinder needs replacing rather than repairing
You don’t need to be technical to spot these. Customers call us when they notice:
The cylinder is leaking from the body
A leak from a valve or joint can be repaired. A leak from the cylinder body itself ‑ rust, weeping seams, water tracking down the tank ‑ means the cylinder has failed, and it needs replacing before it causes damage to your flat and the one below.
Hot water keeps failing
If you’re calling out repairs again and again ‑ lukewarm water, tripping immersion, recurring faults ‑ an ageing cylinder that’s fighting limescale and worn parts may be telling you it’s reached the end of its life.
It’s old, noisy or inefficient
Loud banging, slow reheating and rising running costs are all signs of heavy limescale and a tired element. A modern, well-insulated cylinder heats faster and holds heat longer ‑ which matters on an electric system.
Correctly sized for your flat ‑ not just like-for-like
Fitting the wrong size cylinder is a classic mistake. Too small and you run out of hot water; too big and you waste money heating water you never use. We size your new cylinder around how you actually live ‑ number of bathrooms, showers and occupants ‑ and the space available in your apartment. Whether it’s a straight like-for-like swap or a better-suited unit, you get the right cylinder, not just the nearest one on the van.
We fit the common apartment brands ‑ OSO, Megaflo, Gledhill, Santon, Heatrae Sadia, Telford and similar ‑ so we can usually match or upgrade what you already have.
Tidy pipework and a proper certificate
A cylinder replacement is only as good as the installation around it. We take the time to leave the pipework clean and level, the valves accessible, and the discharge (the safety pipe that releases water if pressure ever gets too high) run correctly. Because unvented cylinders are pressurised, the work must be done by a G3 qualified engineer ‑ that’s simply the recognised qualification for working safely on these systems. Every replacement we fit is certified, so it’s safe, legal and ready for its warranty.
Replacements for Manchester apartments and landlords
We work across the city’s apartment areas ‑ Manchester city centre, Salford, Deansgate, Ancoats, the Northern Quarter, MediaCity, Castlefield, Hulme and the surrounding developments. We’re used to the practical realities of city-centre flats: tight airing cupboards, shared risers, high-rise pressures and parking. For landlords and letting agents, we can replace failed cylinders quickly to get a property back in use, with clean paperwork and per-property invoicing.
Straight-talking quotes, no pressure
HotFix is the specialist hot water arm of City Centre Maintenance MCR Ltd ‑ registered and fully insured. We give clear quotes with the cylinder, the labour and the certification set out, so there are no surprises. If we think a repair would still serve you well, we’ll say so rather than sell you a new cylinder you don’t need. Every installation is invoiced and guaranteed.
How long does a cylinder replacement take?
A straightforward like-for-like unvented cylinder replacement is usually a one-day job. If the pipework needs reworking, or access is tricky ‑ common in high-rise Manchester flats ‑ it can take a little longer, but we’ll give you a clear timescale with your quote so there are no surprises on the day.
Common questions about cylinder replacements
How long should a hot water cylinder last?
A well-made unvented cylinder that’s been serviced typically lasts around 10-15 years. Hard water, a lack of servicing and a worn expansion vessel all shorten that. If yours is getting on and causing repeated faults, planning a replacement beats an emergency failure at the worst possible moment.
What size cylinder do I need?
It depends on how many bathrooms and people the flat serves, and the space available in your cupboard. We size it around how you actually use hot water, so you don’t run out ‑ and don’t pay to heat water you never use.
Will you take away my old cylinder?
Yes. We remove and dispose of the old cylinder and leave the airing cupboard clean and tidy, with the new unit installed, tested and certified.
