What is Instant Hot Water Dispenser
An instant hot water dispenser(also known as an instant hot water tank) is a kitchen appliance that provides near-boiling hot water on demand, eliminating the need to wait for a kettle or stove to heat up. It typically consists of a small, insulated tank connected to a special faucet that stores and heats water, delivering it quickly and conveniently for tasks like making beverages or cooking

Types of Instant Hot Water Tanks
Non-pressure hot water tank
A non-pressure hot water tank, also known as an open-loop thermosiphon system, is a hot water tank that operates without an external pump. These tanks are generally cheaper and simpler to install than pressurized systems but are designed to operate at or near atmospheric pressure, making them safer than pressurized hot water tanks.
Our non-pressure hot water tanks also feature an expansion chamber system that automatically regulates pressure and prevents dripping by back-priming when the tap is closed.
When considering a dependable and safe hot water system, a non-pressure hot water tank is an excellent choice for many households.
Pressure hot water tank
A pressure hot water tank is a modern water heating solution that provides high-pressure hot water throughout your entire home. Unlike older gravity-fed systems, a pressure hot water tank connects directly to the mains water supply. This direct connection ensures strong, consistent water pressure to all your taps, showers, and appliances simultaneously. Also known as an unvented cylinder, this type of hot water tank can be powered by various energy sources, including electricity, gas, or even solar power, making it a versatile and efficient choice for contemporary homes and apartments

Benefits of Instant Hot Water Dispenser
They’re built to last
Because they get a lot of daily use, hot water dispensers need to be robust, sturdy, and capable of withstanding moves, knocks, and multiple uses. Each of our dispensers is easy to use, built using premium-grade stainless steel, and comes with a 100% warranty for complete peace of mind.
Ultimate convenience
With smaller tanks of either 2.4 or 4-litre capacities, each instant hot water dispenser gives you the ultimate in efficient convenience. And, depending on your choice of model, our dispensers are small enough to be installed on a worktop or even wall-mounted.
Hot water on demand
After an initial heat-up time, each dispenser can give you up to almost 4 litres of hot water on demand every hour. Heating the water to 98ºC, the in-built system keeps the water hot and prevents any over-boil or boil-dry issues.
Energy efficient
Instant hot water dispensers are more energy efficient, especially for eco-conscious workplaces and offices aiming to reduce their energy outgoings.
Limescale reduction
If you live in an area with hard water, you may notice a build-up of a white, chalky residue in your kettle. This is limescale. Over time, limescale can come off the kettle and ruin a hot beverage, while its flavour will affect the quality of your cuppa on a daily basis. Limescale reduction filters in hot water dispensers help avoid this problem.
Stylish design
Mains-fed water dispensers, have a design that prizes style as much as substance. Features guarantee the dispenser will never run dry and provide water at the desired temperature with mechanisms ensuring the safety of all users. All this within sleek, polished models which are as much a feature of a contemporary office kitchen as they are a space and time-saver.
