Water Boiler vs Kettle – which is best for your business?

A commercial water boiler – often known as an instant hot water dispenser – is a time-saving alternative to traditional kettle. Ideal for both staffed and self-service use in office kitchens, common areas, event rooms, reception areas or canteens, our plumbed-in hot water dispenser is well worth considering if you’re looking to cut costs and boost productivity. 

While similar in terms of like-for-like energy consumption, there are other key differences to consider in the water boiler vs kettle comparison. It’s true that a boiler will become cheaper and cheaper to run the more you use it, but the main benefit of choosing a mains-plumbed countertop water boiler is the reduction in time spent waiting for water to boil throughout the day (or night shift).

Are water boilers more efficient than kettles?

It costs less to keep a water boiler hot than it does to constantly refill and boil a kettle lots of times. Here’s a working example of how kettle vs water boiler costs might look in your business.

Kettle - 80p per day

Assuming a department or small business has 20 staff, who all enjoy four cups of tea or coffee through the day. This adds up to 80 mugs between them, and with only 5 mugs on average from each boil your kettle won’t be get much of a break – even if your staff are.

16 boils @ 4 minutes each = 64 minutes boiling time every day lost to the kettle

That’s potentially over an hour of waiting every single day – and while they’re boiling instead of working, you’re paying for it in pounds and pence too.

An average kettle (3kW) takes 4 minutes to boil at each visit. A unit of electricity costs around 12p.

3kW x 0.07h = 0.21 kWh, 0.21 x 12p = 2.5p to boil a full kettle each time which means…

Staff Mugs Boils   Cost per day
20 80 16 16x2.5p 40p
30 120 24 24x2.5p 60p
40 160 32 32x2.5p 80p

Water boiler - 68.5p per day

A 3kW boiler on standby will use 0.07kW/h, that’s one unit of electricity (12p) in 14 hours (0.86p per hour), or 20.6p per day. In-use, a water boiler automatically refills and only boils the water used at each serving. It ‘heats’ for 30 seconds per mug of water drawn-off  (1 minute for 2 mugs, 2 minutes for 4 mugs and so on).

For 20 people drinking 80 mugs, the dispenser will be on for 40 minutes (0.66 hours) throughout the day (3kW x 0.66h = 1.98kWh 1.98 x 12p = 23.7p per day). Add this to the standby cost of 20.6p per day and we get…

Staff Mugs Cost per day
20 80 44.3p
30 120 56.6p
40 160 68.5p

Water boilers are built for business use, so they’ll last longer too. The heating element in a household kettles often found in the office kitchen simply aren’t up to the task, so in addition to the running costs outlined above, you can expect to replace them regularly if you stick with them.
