Ideal Home’s Renovation Editor tested the Morphy Richards HeatFlux 2.5kW digital oil-filled radiator at home for two weeks. The review describes a modern-looking design, straightforward controls and measured temperature rises in two rooms, but does not establish how its running costs compare with other heaters.
Ideal Home’s Renovation Editor has tested the Morphy Richards HeatFlux 2.5kW digital oil-filled radiator in two rooms at home, reporting that it raised the temperature in an approximately 18-square-metre living room by 3.5°C in an hour and 5.2°C in two hours. The review, which also notes its digital controls and contemporary appearance, gives readers practical test results for a portable heater advertised for rooms up to 25 square metres.
The reviewer used the radiator in the living room and kitchen diner of a 1970s three-bedroom home for two weeks. The living room measured about 18m²; the kitchen diner was about 22m². In the living room, the reviewer said the temperature rose by almost 1°C within 10 minutes on high heat, then by about 3.5°C after an hour and 5.2°C after two hours. These are results from that home test, not a guarantee of performance in other buildings.
In the larger kitchen diner, the reported ambient temperature increase was 2°C over two hours. The reviewer said the room felt less cold after about 30 minutes, wherever they stood. The test account does not specify the starting temperatures, outdoor conditions, energy use measured during the test or how the readings were independently verified.
The unit has low, medium and high heat settings, an eco mode, a thermostat adjustable from 5°C to 30°C, a timer and remote control. Its 2,500-watt rating and stated suitability for rooms up to 25m² are product specifications. Ideal Home lists a recommended retail price of £99.99, a weight of 9.9kg and dimensions of 46.4 by 63 by 24.5cm. It is offered in grey and white, and has no smart features, according to the review.
Measured Warm-Up in Two Rooms
The test offers a household-scale account of how one portable electric heater performed in rooms within its advertised size range. Readers comparing ways to heat a single room can use the reported temperature changes and warm-up times as a point of reference, while keeping in mind that results depend on factors such as insulation, room layout, starting temperature and weather.
The controls may also matter for day-to-day use. The reviewer found the display and touch buttons straightforward and said the remote offered the same functions as the controls on the unit. A timer can be set to switch the radiator on or off after one to 24 hours, while eco mode adjusts power based on the target and ambient temperatures, as described in the review.
However, the report does not show that the heater is cheaper to run than central heating or another electric heater. Its listed hourly running-cost range is 26–66p per hour, but the source does not give the electricity tariff or calculation assumptions behind that estimate. Buyers should treat it as a listed estimate rather than a measured cost from the two-week test.

A Portable Heater for One Room
The review frames the product as a way to warm the room being used, rather than heating an entire home. Oil-filled radiators are electric portable heaters; this model’s 2.5kW rating describes its stated power, while the manufacturer’s suggested room limit is 25m². The source does not report a comparison with other products tested under the same conditions.
Setup took the reviewer less than five minutes, including attaching the wheels. The radiator weighs 9.9kg, and the reviewer said turning it over for assembly was manageable. The remote control did not come with its required CR2025 battery, an added detail for shoppers to factor in. The review also notes cardboard packaging alongside a plastic bag and polystyrene.
““My first thought when using the Morphy Richards HeatFlux 2.5kW digital oil-filled radiator was just how user friendly it is.””

Limits of the Home Test
The review describes results in one home over two weeks, but does not provide a full testing log, the rooms’ insulation details, outdoor temperatures or the starting temperatures for each heating session. Those conditions can affect how quickly a room warms, so the reported increases should not be read as universal performance figures.
The source also does not report measured electricity consumption, a cost comparison with central heating, or a comparison against competing radiators. While it lists running costs of 26–66p per hour, it does not state the tariff, date or calculation method behind the range. The material provided does not include a final verdict on whether the reviewer recommends buying the radiator or considers it worth its £99.99 recommended price.

Check Costs Before Buying
The review provides a two-week test account but does not identify a follow-up test or a future product update. Readers considering the heater can check the current retail price, confirm the electricity tariff used for any running-cost estimate and compare the unit’s size and controls with their room and heating needs. The stated 25m² room limit and test results should be weighed against the conditions in the reader’s own home.
Any future assessment would be more useful if it reported energy use and costs under stated conditions, alongside comparable results for other heaters. Until then, the confirmed evidence here is limited to the reviewer’s observations in two rooms and the product specifications supplied in the source.

Key Questions
What did Ideal Home report about the HeatFlux’s heating performance?
The reviewer reported that in an approximately 18m² living room, the temperature rose by about 3.5°C in an hour and 5.2°C in two hours. In a roughly 22m² kitchen diner, it rose by 2°C over two hours. These are results from one home test.
How large a room is the radiator designed for?
The product is listed as suitable for rooms of up to 25m². The source does not establish that it will heat every room of that size equally; insulation and other room conditions can affect performance.
What controls and settings does it have?
The radiator has three heat settings, eco mode, a thermostat adjustable from 5°C to 30°C, a timer and a remote control. The reviewer said the remote could perform the same functions as the on-board controls.
What is the price and what does the review say about running costs?
The source lists a £99.99 recommended retail price and an estimated running-cost range of 26–66p per hour. It does not state the tariff or calculation behind that estimate, and it does not provide measured running costs from the home test.
