Frequently Asked Questions

A Quooker tap does not require routine servicing. Maintenance is only needed if performance declines, for example due to limescale or reduced water flow. To ensure your tap is always kept in the best condition, clean the tap with only hot water and a soft cloth. We strongly advise against the use of other cleaning agents and scouring pads.

Basic maintenance such as cleaning and descaling can be done yourself. For safety and reliability, full servicing should be carried out by Quooker or a qualified professional. For more information about maintenance, click here.

At Quooker, sustainability has been high on our requirements list right from the first product concept. Our tanks are manufactured with vacuum insulation that ensures that the energy loss is minimal. This has always been the case, and will remain so in the future. The introduction of the label qualification by the EU confirms that Quooker boilers are sustainable.

The energy label that an appliance carries is determined by its energy efficiency. Due to energy loss in the generation of energy in power stations in 2015, an electrical appliance can achieve a maximum energy efficiency of 40%. The loss (non-beneficial use of the energy) that an appliance suffers, in Quooker's case the standby power consumption, reduces this efficiency further still.

Because a Quooker is fitted with high-vacuum insulation cladding, the energy loss, is only 10 watts. Due to this, the total energy efficiency for the Quooker COMBI tank is 36% and this results in an A label for the Quooker COMBI tank in the XXS category.

A Quooker clicks when it turns on and off, but otherwise is silent. The heating element heats the water to optimum temperature and the tank stores it. The water supply pressure ensures that the water does not ‘bubble’ and therefore the appliance is silent.

In order to verify the calculations conducted, a practical test is conducted on the energy efficiency of the Quooker COMBI tank. The report with the detailed results from this test, conducted in accordance with the standard ‘NEN-EN 50440 Efficiency of domestic electrical storage water heaters and testing methods’, can be requested from Quooker.

The Quooker COMBI tank is a product that delivers hot water as well as boiling water. Because the COMBI tank complies with these requirements, it falls into the category “boilers” and it is mandatory to label it.

The energy label an appliance carries depends on its energy efficiency. Due to the energy loss in the generation of energy in power stations in 2015, an electrical appliance can achieve a maximum energy efficiency of 40%. The energy loss (non-beneficial use of the energy) that an appliance suffers, in Quooker’s case the standby power consumption, reduces this efficiency still further. Because a Quooker COMBI reservoir is fitted with high-vacuum insulation cladding, the energy loss is only 10 watts. Due to this, the total energy efficiency for the Quooker COMBI tank is 36%, resulting in an A label for the Quooker COMBI tank in the XXS category.

If you have a chrome, stainless steel, nickel or gold tap, use glass cleaner or water with a soft cloth. If you're using glass cleaner, spray a small amount on a damp cloth (not directly on the tap) and then wipe the tap. Wipe it dry with a clean cloth straight away.

If you have a patinated brass, rose copper or black tap, use warm water and a soft cloth only. Dry the tap immediately after cleaning.

• The Quooker PRO3 tank requires 50 cm of height space and is 15 cm in diameter.
• The Quooker COMBI tank requires 58 cm of height space and is 20 cm in diameter.
• The Quooker COMBI+ tank requires 53cm of height space and is 20 cm in diameter
• The CUBE system requires a 500 mm in height, 223 mm in width and 340 mm in depth
• If you have specified a Flex tap please note we require at least 500 mm deep x 200 mm wide space below the tap position under the worktop in the cupboard. This is required to allow the weight that operates the Flex hose to move freely up and down. If it becomes restricted it will not operate as intended.

• Connection is to existing services that must be live and working, and we must be provided with clear details of where we can isolate either the water and or the power if required when we attend
• Services required - 13 amp power socket (2 x 13 amp if a CUBE is specified) waste, hot and cold water supply. These services must be within 500mm of the intended install location below worktop height and fully accessible. If only one socket is available and a CUBE is required, a Powerswitch can be added
• The minimum hot and cold water pressure required is 2 bar. COMBI tanks only require a cold water supply
• Space for the tank and any accessories required

If the criteria above have not been met on the arrival of the engineer, a return visit may be required which will be charged to the ordering party at cost of £125 inc. VAT. You can read more about Quooker installation requirements by clicking here.

A Quooker doesn't need any special maintenance, but if you live in a hard water area, there's a chance that limescale could build up in the end of the tap.

If water is flowing more slowly than usual, unscrew the nozzle and take out the ‘aerator’ from the tap end. Soak it in a small cup of white vinegar for one hour. Rinse off any limescale and put the tap back together.

If the water is still flowing slowly, there might be limescale inside the tank. If that’s the case, it will need to be cleaned.

Quooker can arrange this for you. You can book a routine maintenance here.

If you'd prefer, you can clean the tank yourself at home using our maintenance kit, which can be ordered here. Just enter your serial number to find the correct kit for your Quooker.

Provided the water is potable, with a pH between 6.5 and 9.5, no excess salt, the softener is maintained in line with the manufacturer's instructions, and there is good inward water pressure of 2 bar or more, your Quooker can be connected without issue.

Yes, as long as the installation requirements are met.

If you're installing a Flex, Front, or Fusion tap, you won't need an additional hole to be drilled in to your worktop as this will replace your existing mixer tap.

If there isn't enough space under the sink for your Quooker tank you can use a Quooker extension hose to install the tank up to two metres from the sink. You can order an extension hose as an optional extra at the same time you order your Quooker.

All Quooker taps dispense boiling water with a push-push-turn of the bezel, which is the ring at the base of the tap spout.

The patented operation was inspired by a child-safe medicine bottle to prevent children, and people who have never used a Quooker before, from accidentally dispensing boiling water.

A Quooker system consists of a small tank in the kitchen cupboard that is connected to the Quooker tap on the worktop.

Our patented vacuum insulation system holds water under pressure at the optimal temperature.

This lets you have 100°C boiling water whenever you need it, without the need to continually boil water, or bring water up to the boil for each use.

With a CUBE tank added underneath the sink you can also have chilled filtered and sparkling water, all from the same tap.

• Verify that the power supply is functioning and the power LED is illuminated.
• If the failure LED is illuminated, press the reset button.

• Check the flow and pressure controller for functionality.
• To test, close the outlet flow. If the pump continues to run, replace the controller.

• Ensure there is a proper feed supply to the pump.
• Check that the feed supply and inlet are clear of debris or any material blocking the flow.

Loss of air charge in vessel, too much air charge in vessel, check inlet for debris, pressure/flow switch clogged, leak in system, toilet valve passing.

• Make sure the pump is properly primed.
• Check that the priming port is fully tightened.
• Verify that water is not leaking from the pump elsewhere.
• Inspect the pressure controller to ensure it’s working correctly.
• Check the flow direction to ensure the pump is running in the correct direction.

Yes, flexi hoses will reduce vibration noise from booster pump.

Test the capacitor to ensure it’s functioning properly and replace it if needed.

Tucson MetaBoost booster pumps are maintenance free pumps, however we recommend the operator / installer ensures to inspect and clean the inlet filter once a year or as required.

Should the pump be used infrequently, it is advised that the pipework is removed for inspection and to allow the pump to be drained before restarting.

For storage purposes, all main components should be cleaned of debris and provided with a rust-proof treatment, then stored in a dry and ventilated area.

The extra cable is for Pulse Width Modulation – operates like a switch which constantly cycles pump on and off thereby regulating the amount of power the pump gains. This is not usually required in domestic applications.

The Tucson 8m circulating pump incorporates an Automatic Air Venting mode feature, it does not have a conventional screw type manual venting system – see attached guide for using this feature.

Circulating pumps generally require little maintenance. However, it's a good idea to regularly inspect for leaks and ensure the pump is functioning correctly. If the system operates in an area with hard water, the pump may need occasional cleaning to prevent buildup.

Yes, it is possible to install a circulation system in homes that use tankless water heaters. However, it is important to make sure the hot water recirculation pump is capable of providing the necessary minimum flow rate to activate the tankless water heater properly.

Yes, in most cases, a hot water circulation system can be added to an existing plumbing setup. However, the installation process and its complexity will depend on how your current system is laid out. To determine the best approach, it’s a good idea to consult with a qualified plumber or HVAC professional who can evaluate your home’s specific requirements.

Yes. Tucson circulating pumps are built to meet ErP (Energy-related Products) regulations, ensuring high energy efficiency and alignment with EU standards. This means you’re not only saving energy but also staying compliant with modern environmental legislation.

While circulation provides instant hot water, it can increase heat loss through the pipes. This can be minimised with insulated piping and smart pump control. Tucson pumps support programmable or demand-based operation to reduce run times, helping cut energy use without sacrificing comfort.

Not necessarily. Hot water recirculation typically requires only a low flow rate, so oversized pumps aren’t needed. In fact, using a pump that’s too powerful can cause noise, increased wear on pipes, and unnecessary energy use. Tucson pumps are specifically engineered for domestic systems, offering the right balance of performance and efficiency.

Hot water circulation can be managed using several smart methods, including temperature-based activation, or demand-driven systems that use sensors to detect usage patterns.

Tucson circulating pumps settings include;
CP (Constant Pressure) – Systems with TRVs with an auto bypass and underfloor heating.
PP (Proportional Pressure) – Systems with TRVs with no minimum flow requirements.

Domestic hot water circulation is a method used in plumbing systems to ensure hot water is readily available at fixtures like sinks and showers. Instead of waiting for water to heat up, the system circulates hot water through the supply lines so it's immediately accessible when a tap is opened.

Additional Information:
Without a circulation system, the water sitting in the pipes between the heater and the fixtures cools down over time. As a result, when you turn on a tap, the cold water must be flushed out before the hot water arrives—often taking several minutes in larger setups. This delay not only wastes time but also a considerable amount of water.

To improve energy performance and reduce environmental impact, these systems often include pumps that meet ErP (Energy-related Products) compliance standards. This ensures the circulation components are energy efficient and adhere to current regulatory requirements.

Any components of the pump that come into contact with water should be made from corrosion-resistant materials. This is important because tap water contains dissolved oxygen and salts, which can be highly aggressive toward metal parts.

The pump’s hydraulic performance should be properly matched to the actual needs of the system. Hot water circulation typically requires only a low flow rate, so using a high-powered pump is unnecessary. An oversized pump can lead to higher energy consumption, increased noise, and accelerated wear on piping—especially if the system runs continuously.

To reduce heat loss, it’s also important to limit the circulation period. This can be efficiently managed using smart or automatic control modes, which help maintain comfort while minimizing energy use.

In addition, the pump should comply with ErP (Energy-related Products) regulations, which set minimum efficiency standards for energy-using equipment within the EU and other regions. Using an ErP-compliant pump ensures better energy performance, reduced environmental impact, and alignment with current legislative requirements.

A hot water circulating pump in homes brings multiple benefits, including quick access to hot water and a noticeable reduction in water usage. It also enhances water safety by inhibiting the growth of Legionella bacteria, which has led to such systems being required in several countries.
