Understanding Your Hot Water Tank Repair & Replacement Options
When your hot water tank needs attention, knowing whether you have an open-vented or unvented system is important. Each system operates differently, which can affect both the repair process and replacement options. At Metro Plumb, we service both types, ensuring expert care regardless of your setup. Discover the key differences to help you make confident and informed decisions for your hot water system.
Open Vented Hot Water Systems
Open-vented hot water systems consist of two tanks. The hot water storage tank is typically located in an airing cupboard, while the cold-water feed tank sits at the highest point in the system, often in the loft. The feed tank fills with cold water from the mains supply, which is then sent to the hot water tank to be heated. Heating is typically achieved either by an immersion heater or a coil inside the tank connected to a gas boiler. These systems use gravity to create water pressure, which often results in lower pressure levels.
Once the standard for hot water systems, open-vented systems were widely used until the introduction of combi boilers in the 1980s. They are still common in older homes but can present some challenges. Issues such as a stuck float valve in the feed tank can lead to low water levels, while their open design makes them vulnerable to contamination. Additionally, they are incompatible with combi boilers, so upgrading to this newer technology requires a complete system update.
Unvented Hot Water Systems
Unvented, or pressurised, hot water systems feature a storage tank fed directly from the mains water supply, providing higher water pressure. Unlike open vented systems, they do not require a loft-based tank for expansion and venting, which is where they get their name.
These systems heat cold mains water within the unvented cylinder, storing it until needed. Water can be heated using immersion heaters, a gas boiler through an indirect coil, or increasingly via energy-efficient methods like solar power. Unvented cylinders are versatile, serving both small applications, such as under-sink heaters, and larger domestic or commercial needs.
While generally reliable, these systems have components like pressure-reducing valves, non-return valves, and temperature relief valves that can develop issues over time. Heat source failures can also occur. Unvented cylinder owners must have their system inspected at least once a year to ensure continued safety and efficiency.

Hot Water Tank Repair FAQs
Can I have an unvented hot water system fitted?
As long as you have space in the property with access to mains water supply. The ideal space would be in an airing cupboard.
Can I increase the water pressure from my open-vented hot water system?
Yes, if you have low water pressure coming from the hot water cylinder, we can fit a booster pump which will improve the water pressure across the property.
Why is an unvented hot water system needed?
An unvented hot water system is essential in large properties to ensure mains pressured water is supplied to all appliances. It also removed the need for tanks in the roof space.
How often does an unvented hot water system need to be serviced?
An unvented hot water system should be serviced at least once a year to ensure it remains in optimal working condition.
Is there a problem with my hot water system?
A typical sign of a problem with your hot water system can be water passing through to the warning pipes. If this happens, it is likely the system is gaining too much pressure. Another typical sign you have a problem is lower pressure than normal coming from your taps, if this happens it’s likely you have an issue with your water supply.
What qualifies a plumber to work on unvented hot water systems?
Regardless of the work required, in you are hiring a plumber to conduct work on your unvented hot water system you should ensure they are G3 qualified. At Metro Plumb, we have a growing network of G3 qualified plumbers. Find your local plumber here.
What is the first thing to check when there is no hot water?
Start by ensuring your water heater has power or fuel. Check the circuit breaker for electric systems or the pilot light for gas systems. Confirm that the thermostat is set correctly and the water supply is turned on. If everything appears fine, but there’s still no hot water, the issue may require professional diagnosis and repair.
How long does a hot water cylinder usually last?
A well-maintained hot water cylinder typically lasts 8 to 12 years. However, factors such as water quality, usage, and regular servicing can influence its lifespan. Annual inspections and timely repairs can extend its functionality, helping you avoid unexpected failures.
Is it worth it to repair a hot water heater?
Repairing a water heater can be cost-effective if the issue is minor, such as a faulty valve or thermostat. However, if the unit is older or the repair costs approach hot water cylinder replacement expenses, upgrading to a new, energy-efficient system can be the better long-term option.
Can I install a hot water cylinder myself?
Installing a hot water cylinder is a complex procedure that requires professional expertise. Incorrect installation can pose safety risks, such as pressure issues or leaks. A qualified engineer ensures the system meets legal and operational standards, providing peace of mind and compliance.
