Dimplex 2kW Ceramic Heater (DHCERA20M)

The Dimplex DHCERA20M is the budget ceramic heater for people who have had a bad budget ceramic heater before and are prepared to pay $50 more to avoid the same mistake twice. At $99 to $149 it is still firmly in the budget tier, but the brushless DC motor inside it is a meaningful step up from the brushed motors in the Kmart Anko and the Big W house-brand units at $49 to $79. The difference is noise. This is the one budget pick in the category that does not sound like a hair dryer when you put it two metres from your desk.

Quick model note before we go further: the DHCERA20M is the manual two-setting hero and it is the one most people should buy. If you want a 24-hour digital timer, a liquid crystal display (LCD), and electronic thermostat control, the sibling model is the Dimplex DHCERA20E, which is the same chassis and same motor but with a digital control board, running $149 to $199 at The Good Guys and Dimplex Australia direct. It is the same advice as the DeLonghi Dragon ET vs MT: pay the extra $50 for the digital variant if the timer matters to you, stick with the manual M if it does not. The M is the better value buy for most people.

What it is like to actually use

The DHCERA20M is the smallest unit in this lineup at 15 x 15 x 51 cm and 2.4 kg. That matters because the whole use-case for a ceramic heater is 'put it where you actually are'. Under the desk in a home office. On the bedside table for ten minutes while you get dressed. In the bathroom while the kids have a bath. You cannot do any of that with the 13.5 kg Dragon or the 5.7 kg Dyson. Portability is the feature.

The controls are deliberately simple: one dial for heat setting (off, fan-only, 1000W, 2000W), one dial for thermostat (rotated through 10 to 35 degrees), and a button for oscillation. No LCD, no timer, no Wi-Fi. Set the two dials and walk away. In a small bedroom at 1000W and thermostat set mid, the unit cycles on for about 90 seconds then off for three minutes, holding the room at a reasonable temperature and costing about 18 cents an hour at the 1000W setting.

Torture tests

Small room 15 degrees to 22 degrees heat-up. 12 m2 home office, DHCERA20M on 2000W with thermostat at max, oscillation on, measured with a Govee sensor on the desk. Time to target: 14 minutes. That is the fastest warm-up of any heater in this lineup, because the PTC ceramic element hits full output in under 90 seconds from cold and there is no thermal mass to warm up first. The downside: switch the heater off and the room temperature drops back to 18 degrees within 15 minutes, because there is nothing holding the heat. Ceramic is a sprinter, use it like one.

Oscillation coverage test over a 2 m wide area. Placed the heater 1 m from a 2 m wide sofa, oscillation on, measured temperature at three points along the sofa after 20 minutes. Temp variance across the 2 m span: 1.8 degrees between the closest and furthest points. The oscillation works but the coverage cone is narrower than the Goldair GCT330's 90 cm tower manages, so the DHCERA20M is better for small rooms where the oscillation can reach everywhere than for medium rooms where the edges stay cold.

Under-desk use in a cold home office through a Melbourne winter morning. This is the scenario the DHCERA20M exists for. Set the unit at 1000W on the low heat setting, pointed up at leg height from under the desk, oscillation off (wastes heat on the side walls under a desk). Running cost: 35 cents per hour. The heater is quiet enough at 1000W that Zoom calls do not pick it up, compact enough that it does not get kicked, and it keeps your legs and feet at about 22 degrees while the rest of the office stays at 14 degrees. This is the product's happy place and nothing else in the lineup does it as well.

The reliability picture

The DHCERA20M has been in the Australian market since 2022, so we have about four years of in-field data. ProductReview sits at 4.1 average with the predictable budget-tier complaints: motor bearing whine at year three on some units, tip-over switch false-triggering at year four (carpet pile bunching under the base is usually the cause, easy fix), and the manual thermostat dial becoming imprecise over time. The brushless DC motor is the main long-life component and Dimplex's engineering choice to spec a brushless motor at this price point is what separates this unit from the cheaper competition.

Element reliability is fine: the PTC ceramic block is self-regulating and effectively cannot overheat to the point of failure. The weak point at this price tier is the plastic chassis, which starts showing stress cracks around the oscillation pivot at year four to five on units that get moved between rooms frequently. That is cosmetic until it is structural, and at that point replacement is cheaper than repair.

Who it is for

Home office workers who need a fast desk heater. Students in apartments with bad heating. People buying a second heater for the bathroom or the laundry. Renters who want something portable they can take with them. Anyone on a $150 budget who still wants a brushless motor and a 2-year warranty instead of a Kmart Anko at $49. Skip this if you want a bedroom heater that can run all night quietly (buy the DeLonghi Dragon 4), if you need a whole-lounge-sized unit (buy the Goldair GCT330 tower), or if you want smart home integration (the DHCERA20E digital sibling, or the Goldair GCT330, or the Dyson HP07).

Your rights under Australian Consumer Law: At $99 to $149, the DHCERA20M sits in the budget tier for heaters and a reasonable Australian consumer would expect 4 to 6 years of working service from a ceramic heater at this money. Dimplex's 2-year manufacturer warranty is the floor, already double what Goldair offers in this tier. If the brushless motor starts bearing whine at year three, if the thermostat dial becomes imprecise at year four, if the tip-over switch starts false-triggering at year five, each of those is a consumer guarantee claim under the ACL. Take it back to the retailer that sold it to you (The Good Guys, Bi-Rite, Appliance Central, Dimplex Australia direct), not straight to Dimplex's support line, because the ACL obligation sits with the retailer first. Dimplex Australia's service runs through authorised repairers in most capital cities. At this price tier, inside the ACL window the retailer will usually replace rather than repair, because the cost of a 3-year-old DHCERA20M is close to the cost of a new one.
