Comparing the Dimplex ML2T vs Eco Chico starts with one important difference: the ML2T is a 2kW convector, while the Eco Chico is a 700W oil-free radiator. They offer substantially different heating capacity. The smaller electricity draw is useful only if the smaller heater can do the job you need.
This is a research-based comparison using manufacturer information checked on 20 October 2026. We have not tested either heater or measured their warm-up speed, thermostat accuracy or real-room consumption.

Dimplex ML2T vs Eco Chico at a glance
| Feature | Dimplex ML2T | Dimplex Eco Chico |
|---|---|---|
| Format | Convector | Oil-free radiator |
| Maximum rated output | 2,000W | 700W |
| Main control | Rotary thermostat | Rotary thermostat |
| Best reason to shortlist | More heating capacity for the room | Compact supplementary heat where 700W is sufficient |
| Full-output cost at 25p/kWh | 50p/hour | 17.5p/hour |
Dimplex’s ML2T product page confirms 2kW output, a rotary thermostat, frost setting and carry handles. Its Eco Chico page identifies the OFRB7N as a 700W oil-free radiator with a rotary thermostat and one heat setting. Check the exact listing rather than assuming similarly named models have identical controls.

Choose heating capacity before the lowest wattage
Imagine a room losing heat at an illustrative 1,000W while you are trying to maintain your chosen temperature. A 700W heater cannot cover that loss by itself, even if it runs continuously. A 2kW heater has more capacity available and may cycle once the room reaches its target. This is an example to explain the choice, not a heat-loss estimate for your home.
The Eco Chico therefore makes more sense to shortlist for a modest top-up in a room that is already partly heated, or a small well-insulated space with a sufficiently low heat demand. The ML2T is the more sensible of these two to investigate when you need greater output. Neither should be chosen solely from floor area; draughts, windows and outdoor conditions change the requirement.
Which one costs less to run?
At full output for four hours, the ML2T uses 8kWh; at 25p/kWh that costs £2. The Eco Chico uses 2.8kWh and costs 70p over the same period. These are maximum-output scenarios at an illustrative tariff, not a measured comparison or a claim that both rooms would reach the same temperature.
A second scenario shows why wattage alone can mislead: a 2kW heater operating for 35% of four hours uses 2.8kWh, the same energy as a 700W heater operating throughout. Whether either pattern is realistic depends on heat loss and thermostat operation. Our our guide to 2kW electric heater running costs explains how to use your own tariff and operating hours.
Oil-free does not mean free heat
The Eco Chico contains no oil, so do not confuse it with an oil-filled radiator. Its format may suit your space and preferences, but “oil-free” is not evidence of a lower cost per unit of delivered resistance heat. Compare the appliance’s total energy consumption and the comfort it provides during your actual routine.
For the difference between radiator-style and fan-assisted warmth, see our oil-filled radiator versus fan heater comparison. It explains the broader choice of heating format; the Eco Chico itself is an oil-free model.
Practical buying checks
Measure the available position, including the manufacturer’s clearances, and check socket access without an extension lead. Consider whether the controls will be easy to reach and read. Verify the model number, UK plug, delivery cost, seller and return terms on the live listing. Prices and availability can change, so compare the total price rather than an old discount headline.
Follow the model’s instructions and Electrical Safety First’s portable heater advice. Keep heaters clear of combustible materials and switch them off when unattended or before sleep. A frost setting is not a guarantee that every pipe in a room will remain above freezing.
Our buying verdict
Shortlist the ML2T when you need the greater heating capacity and want simple thermostat control. Shortlist the Eco Chico when compact supplementary heating is the priority and you have established that 700W is enough. Buying an underpowered heater to obtain a smaller hourly cost can leave the room cold.

Is the Eco Chico an oil-filled radiator?
No. The OFRB7N is an oil-free radiator. Use the exact model documentation when comparing specifications.
Does the ML2T use 2kW all the time?
Its rated output describes operation while heating at that power. A thermostat can switch the element off when the target is reached, so the average over a session may be lower.
