Quick Answer
A commercial pasta boiler holds continuously boiling water with individual portion baskets, an overflow channel, and a drain, cooking portioned pasta in 60 seconds to 4 minutes. A 24-litre tank suits up to about 60 covers per service; above that, step to 40 litres. Expect £600–£1,900 depending on type.
Caterzone supplies commercial pasta boilers and pasta cookers to Italian restaurants, pizzerias, and street-food operators across the UK, and the argument for one over a stockpot is entirely about service. A stockpot cooks a batch; a pasta boiler cooks six separate portions at six different stages simultaneously, which is what a table of six ordering six different pastas actually requires.
This guide covers how pasta boilers work, tank sizing, gas versus electric, starch management, UK gas safety, and running costs, so you can specify the right commercial pasta boiler for your kitchen.
What is a commercial pasta boiler?
A commercial pasta boiler is a dedicated tank of continuously boiling water fitted with individual portion baskets, an overflow channel, and a drain. Each basket holds one portion and is timed separately, so fresh tagliatelle at 60 seconds, dried penne at nine minutes, and filled ravioli at four can all run at once and land together on the pass.
That is the capability a stockpot on a range cannot replicate. In a stockpot, everything shares one water temperature, one start time, and one increasingly starchy body of water; separating portions means fishing them out with a spider and hoping. A boiler also recovers temperature faster, because the element or burner is sized specifically to hold a rolling boil against the thermal load of cold pasta being dropped in every few minutes — a domestic-style pot on a ring drops off the boil and stays there through a rush, which is why pasta cooked during service tastes different from pasta cooked at four in the afternoon.
What size pasta boiler do you need?
Tanks are quoted in litres. The common UK formats are 24–28 litres in a 600mm module and 40 litres or more in a 700mm or 900mm module. More water is better for two reasons that are easy to underestimate: thermal stability, because a larger volume drops less when cold pasta goes in, and starch dilution, because the same amount of released starch is spread through more water.
- 24–28 litres — suits up to roughly 60 covers per service. A Combisteel Base 600 electric pasta cooker is the standard 600mm specification.
- 40 litres and above — for 60+ covers, or where pasta is the dominant order. The Combisteel Base 700 electric pasta cooker covers this bracket.
- Two smaller units — worth considering over one large tank, since it lets you separate gluten-free production entirely and keeps you trading when one is being descaled.
Basket count matters alongside volume. A tank that physically fits six baskets but only holds enough water to keep a rolling boil with three in it is sized wrong. Ask how many baskets can run simultaneously at full load, and buy spare baskets — at £100–£200 each they are worth stocking, because a bent or corroded basket takes a station out of service.

Gas or electric pasta cooker — which is better?
Gas pasta boilers reach a rolling boil faster and cost substantially less to run at UK energy rates — roughly 7–10p/kWh for natural gas against about 28p/kWh for commercial electricity. On a piece of equipment that boils water for the entire service, that gap is the single biggest cost difference between the two, which is why high-volume Italian kitchens default to gas. A refurbished Blue Seal G47 single-tank gas pasta cooker is a well-proven example.
Electric units install without a gas connection and hold temperature very precisely, which suits smaller sites, food halls with no gas supply, and kitchens where the extraction arrangement makes an additional gas appliance awkward. They are also simpler from a compliance point of view.
Put numbers on it. A 9kW appliance running six hours a day at, say, 60% duty uses roughly 32kWh. On electricity that is about £9 a day, £3,300 a year. On gas, roughly £2.60 a day, under £1,000 a year. The £2,000+ annual difference will usually outweigh the higher purchase price and installation cost of a gas unit within the first year on a busy site — but only if you already have gas and extraction in place.
How do you stop pasta water going starchy?
Cooking pasta releases starch that thickens the water, makes it foam over, and eventually coats the pasta in a gluey film that stops sauce adhering properly. In a stockpot the only fix is to stop and change the water, which means a dead station in the middle of service.
A properly specified boiler solves this mechanically. A continuous overflow channel runs around the top of the tank and skims the starch-rich foam off the surface, carrying it to drain — starch concentrates at the surface, so skimming there is far more effective than dilution alone. An autofill connection then tops the tank back up automatically as water is lost to overflow and evaporation, holding the level and the boil without anyone touching it.
Together these let you run a full service without stopping. If you are comparing two boilers and only one has an overflow and autofill, that is not a minor feature difference — it is the difference between a machine that works through a Saturday night and one that needs draining at nine o'clock. For gluten-free service, note that neither feature makes a shared tank safe for coeliac customers: cross-contamination in shared pasta water is real, and a genuinely gluten-free offer needs a separate tank or a separate basket-and-water regime you can document.
Gas Safe, water treatment and UK compliance
A gas pasta boiler must be installed and commissioned by a Gas Safe registered engineer, and serviced annually by one. You will also need a gas interlock system linking the appliance to your extraction canopy, so gas cannot flow when ventilation is off — this is a standard requirement in UK commercial kitchens and one your insurer and EHO will both expect to see. Keep the Gas Safe certificates; they are routinely requested at inspection and at insurance renewal.
Water treatment deserves the same attention as it gets on a dishwasher or steamer. A pasta boiler evaporates water continuously, and every litre leaves its dissolved minerals behind. UK water averages around 243 ppm hardness, so in a hard-water area limescale will build on elements and tank walls within months, cutting efficiency and eventually burning out an element. Fit scale reduction on the fill supply and descale on the manufacturer's schedule.
On the food-safety side, the controls are straightforward but real. Cooked pasta held for later service must be chilled below 8°C — and cooled from hot to chilled within 90 minutes — or held hot at 63°C or above. Drain and clean the tank daily; a tank left with standing starchy water overnight is a microbiological problem and smells like one by morning. Electric units should be PAT tested annually.
How much does a commercial pasta boiler cost in the UK?
Countertop electric pasta cookers cost around £600–£900. Base-mounted 600 and 700-series electric units run £850–£1,500, and gas models £1,200–£1,900. Refurbished units from established brands typically sell at £1,500–£1,800 and represent good value, since the tank, burner, and stainless body are simple, durable components with little to degrade invisibly.
Budget for consumables and accessories separately. Spare baskets cost £100–£200 each — a replacement pasta cooker basket is worth holding in stock — and scale reduction cartridges add perhaps £150–£300 a year in a hard-water area. Against a running cost difference of £2,000 or more a year between gas and electric, these are small numbers, but they are the ones that keep the machine in service.
Frequently asked questions
What is a commercial pasta boiler?
A commercial pasta boiler is a dedicated tank of continuously boiling water with individual portion baskets, an overflow channel, and a drain, built to cook portioned pasta to order in 60 seconds to 4 minutes. Each basket is timed separately, so six portions can be at six different stages at once — something a stockpot on a range cannot do.
What size pasta boiler do I need?
Tanks are quoted in litres, typically 24–28 litres in a 600mm module and 40+ litres in a 700 or 900mm module. More water means better thermal stability and less starch concentration through service. A 24-litre tank suits up to about 60 covers per service; above that, step up to 40 litres or run two units.
Gas or electric pasta cooker — which is better?
Gas pasta boilers reach a rolling boil faster and cost less to run at UK energy rates — roughly 10p/kWh against 28p/kWh for electricity — which matters on equipment running all service, so they suit high-volume Italian kitchens. Electric units install without a gas connection or Gas Safe certification and hold temperature precisely, suiting smaller sites.
How do you stop pasta water going starchy?
Cooking pasta releases starch that thickens the water, makes it foam, and eventually coats the pasta.
