OUR PICK OF THE BEST

QUOOKER FLEX

PROVIDES cold, hot, filtered cold and ‘true boiling’ water, and has a flexible, pull-out spray tap, too.

PRICE: From £1,150, including installation, quooker.co.uk

PROS: Good safety features — a safety stop means boiling water cannot be activated if the hose is in use, while child-proof double push and turn handles stop children selecting the boiling water function. Water flows as a fine spray, rather than a fast jet, thus reducing the risk of scalding.

CONS: Not as sleek as some rivals. 8/10

GROHE RED DUO

A 3-IN-1 tap for dispensing kettle-hot, hot and cold water, with swivel head for ease of rotation and a child-proof feature for safety.

PRICE: £1,799 plus VAT and installation, grohe.co.uk PROS: Sleek look. CONS: Despite its insulated sides, parts of the tap feel hot. 7/10

INSINKERATOR 3N1

ONE handle gives instant boiling water, while another does normal hot and cold (pictured left). PRICE: £729 including installation, insinkerator.co.uk PROS: The price. CONS: The water reached a maximum of 96 degrees. 6/10

CLAIMED to be the world’s most advanced drinking water appliance. The premium model (right) has boiling, chilled, still, even sparkling options.

PRICE: From £2,886 including VAT, plus £ 300 installation, water coolersdirect.com

PROS: Energy-saving auto-sleep mode and 25 times better filtration than water filter jugs.

CONS: The cost. 8/10
