The EMtronics 2000W Portable Convector Heater with Timer goes first because it is the newer design. ## About the De'Longhi HSX2320 The HSX2320 is a wall-hugging convector heater that stands on castor feet. The body is 683 mm wide, 460 mm high and about 90 mm deep, and the brand lists 200 mm deep with the feet fitted. It weighs 4 kg and has carry handles, so it moves between rooms easily. The heating element is a wire element, and the convection effect gives gentle, steady warmth rather than a fast blast. Power runs from 800 W to 2000 W. UK retailer Appliances Direct lists three heat levels, and the brand's page gives the range without naming the steps. A mechanical thermostat dial sets the temperature, so there is no readout, and there is no timer or remote. An anti-frost function switches the heater on if the room falls below 5°C, according to Appliances Direct. The brand lists a safety thermostat and double insulation. The cable is 1.5 m, per Appliances Direct. De'Longhi describes it as a spot heater for small and medium rooms, and says it is only suitable for well insulated spaces or occasional use. Appliances Direct puts it at medium rooms of 10 to 20m². The brand's page lists only the heater itself in the order summary. Note that the HSX2320F sold abroad is a different, fan-assisted model, and this one has no fan. ### Key specs - Power: 800 W to 2000 W (2kW), 230 V, 50 Hz - Heat settings: 3 (per Appliances Direct) - Thermostat: Mechanical dial, safety thermostat - Frost protection: Switches on below 5°C (per Appliances Direct) - Size (with feet): 68.3 x 20 x 46 cm - Size (body depth): 9 cm deep - Weight: 4 kg - Cable length: 1.5 m (per Appliances Direct) - Warranty: Brand's page lists a full manufacturer warranty and mentions 2 years with standard legal coverage - Colour: White ## What owners report about the De'Longhi HSX2320 We found very little owner feedback for this exact UK model on pages we could open, so we can't report a clear pattern. Retailer pages for this heater show a high overall owner score, but we could not read the review text, so we cannot say what owners praise or complain about. ## Who the De'Longhi HSX2320 suits It suits someone who wants a plain, low-profile heater for a bedroom, home office or small living room, with no menus or programming. It runs without a fan, and the dial and three settings are easy to work out. The anti-frost function also covers a spare room or porch that you want kept above freezing. Look elsewhere if you want to set a schedule or read the temperature. The EMtronics 2000W Portable Convector Heater with Timer and the Devola 2000W Convector Heater DVCH2BL both have a 24-hour timer, and the Devola adds a digital display and remote. For a large or draughty room, the Dimplex ML Convector Heater 3kW ML3TSTie7 has more output. The brand itself limits this model to well insulated spaces or occasional use. ## Questions about the De'Longhi HSX2320 ### Does the De'Longhi HSX2320 have a timer?

Too few review sites cover convector heaters for their verdicts to lead, so this ranking is led by owners. It ranks products by how happy owners are, holding back any product few owners have rated until more agree. How many rated it and how new it is only settle close calls, and value for money earns its own badge rather than a higher place. We compared 19 models for this guide before settling on these ten. Brands can't pay to be included or to move up. We last checked these picks in October 2026.
