For reheating onion gravy on a small worktop, compare external dimensions and the space needed around the microwave before choosing by capacity. A 17L solo model can suit modest portions if your microwave-safe jug fits and rotates freely; a compact 20L model gives you more room for other dishes, but still needs a placement check. Consider a built-in model only after confirming the cabinet and installation requirements for that exact appliance.
If you mainly heat modest portions of gravy, sauces or leftovers, start with the appliance’s external dimensions. Russell Hobbs lists its RHMM701R at 451 mm wide, while the Haden 212443 listing gives an approximate width of 420 mm; both still need space for the clearances specified in their instructions.
If the same microwave must also take plates and larger bowls, measure your usual dishes as well as the worktop. Panasonic specifies a 255 mm turntable for the 20L NN-E27JW, compared with the 24.5 cm turntables stated for the cited 17L Russell Hobbs and Haden models.
If keeping the worktop clear matters more than being able to move the appliance easily, a built-in microwave is another route. The CDA VM551SS is described by Joybuy as a built-in wall-unit model, but cabinet fit must be checked against its exact installation instructions.
Consider it when: Small portions are the main task and a compact appliance fits your measured worktop.
Trade-off: The 24.5 cm turntables stated for the Russell Hobbs RHMM701R and Haden 212443 may limit which larger dishes can rotate.
Consider it when: You also want room for everyday plates; Panasonic specifies a 255 mm turntable for the NN-E27JW.
Trade-off: A larger cavity does not settle worktop fit: the NN-E27JW measures 443 × 330 × 258 mm externally, according to Panasonic, before any required clearance.
Consider it when: Freeing the worktop is the priority and you have a suitable cabinet.
Trade-off: Cabinet cut-out, ventilation and electrical requirements must match the exact model; a built-in product description alone cannot establish fit.
| Concern | What to check | Who this matters to |
|---|---|---|
| Worktop space | Measure usable width, depth and height; check the exact model’s external dimensions, door opening and ventilation instructions. | I need the microwave to leave room for preparing food, so placement comes before cavity size. Around 50% of consumers put worktop fit first. |
| Gravy reheating | Look for suitable power and timing controls, and check that your microwave-safe jug rotates freely. Follow stirring and standing instructions where provided. | I want to pause, stir and check a small serving rather than leave it heating unchecked; for around 30% of consumers, controlled reheating is the main concern. |
| Other everyday uses | Compare turntable diameter with your usual plates and bowls; consider defrost and other controls only if you will use them. | If I also heat full plates or larger leftovers, dish room matters beyond the gravy jug. Around 20% of consumers prioritise those wider uses. |
Microwaves with the same cavity capacity can have different external dimensions. Litres alone cannot tell you whether an appliance and its required clearances fit the intended position.
Measure the available space in millimetres, then compare it with the exact model’s dimensions and placement instructions.
Microwave heating can be uneven. Food Standards Agency home guidance says to follow packaging instructions on stirring and standing; GOV.UK food hygiene guidance for businesses advises reheating until food is steaming hot throughout and reheating it only once.
Follow applicable product or recipe instructions, stir carefully during reheating and check that the gravy is steaming hot throughout before serving.
A built-in description does not establish the cabinet cut-out, ventilation arrangement or electrical requirements for your kitchen.
Check the installation manual for the exact model against your cabinet and electrical arrangement before ordering.
The Joybuy listing for Haden model 212443 states one year in one area and two years in another, so neither duration should be assumed to govern your purchase.

The RHMM701R is a compact freestanding solo-microwave example for straightforward reheating.
The NN-E27JW illustrates a compact 20L solo-microwave option when gravy is not the only food you heat.
The Classic 212443 is a manual 17L, 700W solo-microwave example for small-portion reheating.
These freestanding solo microwaves offer different capacities and worktop dimensions for reheating gravy and other food. Measure your space and usual microwave-safe dishes before choosing; a built-in installation is a separate decision.

Consider this 800W model if you want five stated power levels for short reheating sessions. For placement, compare its stated 43.95 cm width and 35.9 cm depth with your worktop, then check the required clearance in its instructions.
No image available
Consider this 700W manual model if you prefer setting reheating time yourself. Its stated approximate dimensions are 440 × 345 × 259 mm; check placement clearances and make sure your gravy jug can rotate on the turntable.

Consider this 900W model if you also need to accommodate larger dishes. Its stated width of 51.3 cm and depth of 42.9 cm make careful worktop and ventilation-clearance checks particularly important.

Consider this 800W model if your usual dishes need more room than a small gravy jug. Check whether its stated 48.5 cm width and 39.3 cm depth fit with the required clearance, and confirm the controls for this exact model before buying.
Choose by the space the exact appliance and its required clearances occupy, not by its litre capacity alone. For reference, the Haden 212443 listing gives approximate appliance dimensions of 420 × 320 × 250 mm, while Russell Hobbs specifies 451 × 326 × 258 mm for the RHMM701R. Check the relevant placement instructions before deciding either fits.
Yes, if the gravy has been stored safely and is reheated until steaming hot throughout. Follow applicable packaging or recipe instructions, including stirring and standing where directed. GOV.UK food hygiene guidance for businesses also advises reheating food only once.
It can be, provided your microwave-safe jug fits and rotates freely. The cited Russell Hobbs RHMM701R and Haden 212443 17L models have stated 24.5 cm turntables; measure your jug, especially if you also expect to heat plates or larger bowls.
A built-in microwave can move the appliance off the worktop, but it is suitable only when its exact cabinet cut-out, ventilation, electrical and installation requirements can be met. Check those instructions against your wall unit rather than relying on a built-in product title.
Confirm the warranty terms for the exact model with the retailer or manufacturer. The Joybuy listing for Haden Classic 212443 gives different durations in different sections, so keep the final terms supplied with your purchase.
