Commercial High-Speed Oven Buying Guide: The Complete UK Guide (2026)
A commercial high-speed oven combines convection, microwave, and (in some models) impingement air to cook portions in 30–120 seconds — replacing a salamander, microwave, panini grill, and small static oven in one ventless 13A box. This guide covers what high-speed actually means, how to choose between the three production models in stock at Craven Cooling, the throughput maths that justifies the spend, and the kitchens it should not be sold into.
- Plug-in operation: every model in this category runs on a standard 13A single-phase plug. No three-phase. No DNO upgrade. No £2,500+ supply works.
- Ventless: catalytic conversion plus filtered exhaust means no extraction canopy is required for most installations — confirm with local building control on a high-volume site.
- Real cook times: 12″ pizza ≈ 90 seconds; panini ≈ 45 seconds; pasty reheat ≈ 60 seconds; pre-cooked protein finish ≈ 60–90 seconds; frozen pastry warm ≈ 30 seconds.
- Cavity sizes: Merrychef ConneX 12 / 12e cavity is 12″ × 12″ — fits one panini, one personal pizza, one plated portion. Lincat CiBO+ at 23 L holds two personal pizzas or four paninis.
- Replaces 3–4 appliances: salamander + microwave + small static oven + panini grill in one footprint.
- Power draw: 3.0 kW total — at the limit of 13A continuous. Some sites move to a dedicated 16A radial for headroom.
- UK price tiers (ex VAT, April 2026): entry compact £3,400–£4,000 (Merrychef ConneX 12e); standard £4,400–£5,500 (Lincat CiBO+, ConneX 12); pro/specialist £6,000–£10,000+ (TurboChef Sota, Pratica Forza STi).
- Annual energy cost: 3.0 kW × 6 hr/day × 6 days/week × 50% duty cycle × 27p/kWh ≈ £760/year — about a quarter of a typical electric combi.
The high-speed oven category exists for one reason: cafés, QSR sites, takeaway operators, sandwich shops, and bakery cafés do not need a 6-grid combi cooking 100 covers a service. They need 60-second panini, pizza, pasty, and frozen-protein finishing — at high throughput, on a 13A socket, with no canopy build-out. That is exactly what this category delivers, and exactly why a £4,000 high-speed oven often makes more business sense than an £8,000 combi for that operation.
This guide is written for the trade buyer making that call — café owner, QSR operator, hotel breakfast manager, bakery owner, or operator looking to free up bench space. We cover the technology, the three production models in stock at Craven Cooling, the throughput maths, and the year-one total cost of ownership that consistently lands lower than any combi.

What Counts as a “High-Speed Oven”?
The category sits between the microwave (cooks fast but does not brown) and the convection or combi oven (browns and cooks but takes minutes, not seconds). High-speed ovens combine two or three heat sources in one cavity to do both at once.
Convection — a heating element heats air, a fan circulates it. Browns surfaces, cooks the outside. Slow on its own.
Microwave — drives moisture to vibrate, cooks the inside fast. Does not brown.
Impingement — high-velocity hot-air jets aimed at the food top and bottom. Faster heat transfer than standard convection. Used by Merrychef ConneX 12 (impingement plus convection plus microwave) and Pratica Forza STi.
A high-speed oven runs two or three of these at the same time. That is the difference between 60 seconds for a panini in a high-speed oven versus 4 minutes in a panini grill.
| Appliance | Cooks | Browns | Speed (1 panini) | Footprint |
|---|---|---|---|---|
| Microwave | ✓ | ✗ | 60–90s heat-through, no crust | ~50 cm wide |
| Salamander | surface only | ✓ | 2–3 min | ~60 cm wide |
| Panini grill | ✓ | ✓ | 3–4 min | ~38 cm wide |
| Small static oven | ✓ | ✓ | 4–6 min preheated | ~50 cm wide |
| High-speed oven | ✓ | ✓ | 45–90s | ~52 cm wide, single unit |
Real Cook Times by Food Category
These are field-typical times on a Merrychef ConneX 12 or Lincat CiBO+ at full setpoint. Times vary by load size and starting temperature.
Panini / toastie
45–60 seconds- From chilled, single portion
- Crust + melted core in one cycle
- 3-mode (conv + MW + impingement) fastest
Personal pizza (10–12″)
75–110 seconds- From frozen or chilled
- Crisp base via base-plate or impingement
- Pratica Forza STi 60% faster on this category
Pasty / sausage roll
60–80 seconds- From ambient, pre-cooked
- Pastry crisp restored, core to 75°C
- HACCP-compliant reheat cycle
Pre-cooked protein
60–90 seconds- Chicken supreme, salmon fillet, joint slice
- From chilled to 75°C core
- Probe pilots not fitted — set by program
Frozen pastry / Danish
30–45 seconds- Warm-through and crust restoration
- Replaces the slow toaster-oven step
- Hotel breakfast staple
Tray bakes / cookies
90–180 seconds- Single tray batch, conv-only mode
- Effectively a small static oven
- Replaces a counter-top oven on quiet shifts
UK High-Speed Oven Buying Tiers (April 2026)
Pricing splits into three brackets. The compact 12″ cavity covers 80% of the UK use cases; specialist tiers exist for larger pizzas and contract-grade throughput.
High-Speed Ovens We Stock at Craven Cooling
Stocked April 2026. Prices ex VAT. Lead time on stocked units is typically 3–7 working days; ask sales for a current ETA on any specific SKU.
- Convection + microwave (2-mode)
- 3.0 kW total — 13A plug
- 12″ × 12″ cavity
- easyTouch 2.0 controls
- Ventless catalytic conversion
- Made by Welbilt — strong service network
The economy-tier ConneX. Drops the impingement third heat source for a lower entry price. The right call for a café running paninis, pasties, and reheats — not full-service cooking. Pays back fastest as a salamander/microwave replacement on a constrained 13A site.
View Merrychef ConneX 12e →- Convection + microwave + impingement (3-mode)
- 3.0 kW total — 13A plug
- 12″ × 12″ cavity
- easyTouch HD touchscreen, 1,024 programmes
- Ventless catalytic conversion
- USB / network programme transfer
The full Merrychef. Adds impingement air-jets to the convection and microwave, dropping panini and pizza times by another 25–30% versus the 12e. The 1,024-programme bank is the right fit for chain operations standardising menu cooking across multiple sites.
View Merrychef ConneX 12 →- Tri-heat: base plate + convection + microwave
- 3.0 kW — 13A single-phase
- 23 L cavity (195h × 340w × 350d mm)
- Eco mode drops idle to ~1.0 kW
- UK-built, Lincat service network
- Footprint: 395 × 665 mm
Lincat’s response to the Merrychef. Slightly larger 23 L cavity holds four paninis or two personal pizzas at once. The base plate gives a real grilled-bottom finish that the ConneX 12e cannot match. Eco mode at 1.0 kW idle is a meaningful annual saving on long-shift sites. The right call for cafés trading panini and pizza volume.

Year-One Total Cost of Ownership
This is where high-speed beats combi most clearly on the spreadsheet. Same 6 hour/day, 6 day/week café, comparing the ConneX 12e (high-speed, £3,449) with the cheapest credible 6-grid combi (Convotherm Mini Standard 6.10 at £4,300 ex VAT) on the same 13A vs three-phase site.
Two important caveats. First, the comparison is fair only when the operation actually fits the high-speed cavity — single-portion, fast-finish cooking. A combi is the right tool for a 100-cover Sunday lunch service no matter how the spreadsheet looks. Second, the £3,800 extraction line item is avoided by both units only if you do not already have a canopy; on a refurb of an existing kitchen the comparison narrows.
UK Compliance for High-Speed Ovens
Compliance is comparatively light. The category was designed around the 13A plug and ventless operation — which removes most of the building-control burden that combis carry.
Cooked and reheated food must reach 75°C core (Reg 852/2004 retained). High-speed ovens with programmed cycles auto-deliver this for trained cooks; for ad-hoc cooking, use a probe to verify. Hot-hold remains 63°C.
3.0 kW is at the continuous limit of a 13A plug (3,120 W theoretical, BS 1363 derated for prolonged duty). Most installs run on a 13A socket. For multi-shift sites a dedicated 16A radial gives headroom and longer plug life; ask your electrician.
Ventless catalytic conversion typically removes the need for a Type II canopy. On high-volume sites or where the unit is run alongside a fryer or grill, building control may still require a make-up air check. Ask before fit-out.
High-speed ovens do not generate steam. The Pressure Systems Safety Regulations 2000 do not apply, removing the Written Scheme of Examination overhead a combi requires.
All electrical cooking equipment falls under WEEE Regulations 2013 (SI 2013/3113). Producers placing 5+ tonnes/year on the UK market must join a Producer Compliance Scheme; the unit goes back through the supply chain at end-of-life.
Installation and Use Checklist
-
Confirm the socket One dedicated 13A socket or 16A radial within reach of the unit’s lead. Do not run on an extension lead — it is not safe at sustained 3.0 kW draw and voids most warranties.
-
Check clearances Most models need 50 mm to the rear, 25 mm each side, and 50 mm above the cabinet for catalytic converter exhaust. Confirm before sliding into a worktop run.
-
Stable, heat-resistant surface Stainless steel worktop or equivalent. Plastic laminate worktops are fine in most cases but check the manufacturer specification.
-
Cleaning protocol Daily wipe of cavity and door seal with manufacturer-approved cleaner. Catalytic converter typically needs no maintenance for 3–5 years; replacement when it fails the periodic service check.
-
Programme set-up Allow half a day with the manufacturer trainer or your kitchen manager to lock down the 8–12 most-used programmes. Operator-level training takes 30 minutes.
-
Service plan Manufacturer service plans run £350–£500/year for a 4-hour SLA. Worth it for a single-point-of-failure unit in a one-grill café — a dead high-speed oven on a Friday lunch costs more than a year of cover.

A commercial high-speed oven combines convection, microwave, and (on premium models) impingement air to cook portions in 30–120 seconds. Every model in the category runs on a standard 13A single-phase plug, is ventless (no extraction canopy needed in most installs), and removes the steam, water, and PSSR overhead a combi carries. The category replaces a salamander, microwave, panini grill, and small static oven in one ~52 cm-wide footprint, reclaiming about 1.4 metres of bench space. Year-one total cost of ownership on a £3,449 Merrychef ConneX 12e in a 13A café typically lands around £4,800 — roughly a third of the same kitchen's TCO on a 6-grid combi. Craven Cooling stocks three production units in this category: Merrychef ConneX 12e at £3,449 (entry, 2-mode), Lincat CiBO+ at £4,449 (tri-heat with base plate, larger cavity), and Merrychef ConneX 12 at £5,210 (3-mode with impingement and 1,024-programme bank). The decision between them is mostly about throughput volume and chain-recipe standardisation, not about cooking quality — all three deliver 60-second panini and 90-second pizza on a 13A socket.
