Dreo Atom 316 Review: The £50 Fan Heater That Out-Heats Its Size
Dreo’s little cylinder is the heater its UK shop and Amazon listings push hardest, and two UK testers who lived with it came away impressed. It is a 1.5 kW fan heater, though, so it is only cheap to buy. Below you will find what it costs to run an evening at the October 2026 price cap, and the three things that annoy owners.
Where the reviews line up
Our evidence comes from three places: a metered test by Trusted Reviews, a two-week home test by Ideal Home, and the buyer ratings on Amazon UK, where most of these heaters are sold. They agree on most points.
It heats far more than its size suggests. Trusted Reviews logged a medium bedroom going from 17.6°C to 22.4°C in half an hour, and Ideal Home found it warmed a 17 m² bedroom quickly. It is small and light at about 1.25–1.3 kg with a carry handle, so it is easy to move from the office to the bedroom at night. Eco mode is the feature that saves money. In Trusted Reviews’ test it used about a third of the full-power energy once the room was warm.
All the sources make the same complaints. The touch buttons are hard to see because they do not light up. The remote needs a clear line of sight. And it does not oscillate, so it warms whatever it points at. It is also not as quiet as the 34 dB on the box. The testers measured 36 dB and 44 dB at maximum.
What decides whether to buy it is running cost. Flat out it draws 1.5 kW, which is about 39p an hour or £1.58 for a four-hour evening at 26.32p/kWh (our sums). It works well for warming one room for an hour or two. Used as your main heating, it gets expensive quickly.
The three reviews this summary is built from
- Trusted ReviewsEditorial test with a power meter: measured kWh, measured dB and room temperatures.
- Ideal HomeTwo weeks’ use in a bedroom and an open-plan room, February 2026.
- Amazon UK buyers4.6/5. Reported as “nearly 10,000” ratings (TechRadar, 2 Feb 2026) and as 589 on one listing (Latest Deals). We could not open Amazon ourselves.
Before the review: which Dreo is this?
Dreo sells several small heaters with confusingly similar names. The Atom One that dominates US reviews and YouTube is an oscillating heater for the US market. In the UK, Dreo’s own shop lists the Heater 316 (Atom series, model DR-HSH006) at £49.99 in gold or silver, and this page reviews that model. Currys sells two siblings instead. The Atom 416 (£49.99, same cylinder shape, 1.5 kW, no oscillation, 49 dB(A) on Currys’ spec sheet) and the Atom Core (£68.99, 1.5 kW, oscillating, 34 dB(A)) are different products. Check the model number on the listing before you order.

Trusted Reviews
Who they are: Trusted Reviews is a UK tech and home review site whose editors use each product and pair that with industry-standard tests in equipped facilities; it says manufacturers don’t vet its reviews and it never takes money to test, so it is a strong hands-on source.
This is the most useful source we found, because it measures the things that matter. On maximum in a medium-sized bedroom, the air near the heater rose from 17.6°C to 22.4°C in 30 minutes and reached 23.1°C after an hour. A wall thermostat further away read 16.6°C rising to 19.5°C over the same hour. Those are good results for a heater the size of a small pedal bin. The ceramic element reaches full heat in under ten seconds.
The meter readings are what you need for running costs. Flat out it used 0.79 kWh in 30 minutes and 1.5 kWh in an hour. On Eco, which turns the power down once the room reaches the target temperature, it used 0.27 kWh and 0.51 kWh over the same times. The meter also caught a brief start-up peak of up to 2.4 kW. The reviewer measured 47.9 dB at 15 cm and 44 dB at a metre on maximum, both well above Dreo’s 34 dB. The criticisms are about the controls: buttons that are hard to see and not tactile, and an “H1” setting that is easy to misread as “HI”. The fan also runs on for 30 seconds after the heat stops. The verdict is a great choice for a cheap, portable room heater, but not powerful enough for big or draughty rooms.

Who they are: Amy Reeves is an Ideal Home contributor and experienced interiors and renovation journalist who spent five years as Assistant Editor of sister title Homebuilding & Renovating, which is why her two-week home test is worth weighting.
Ideal Home’s tester used the heater for a fortnight in two very different rooms. In a 17 m² bedroom it warmed the room quickly. In an open-plan kitchen, dining and living room it took about 30 minutes to lift the temperature from 15.9°C to 19°C, after which she turned it down. That is about the most you should expect: it can warm a large room, but not quickly. She confirms the three power levels as 1000, 1300 and 1500 W and costed them at 28p, 36p and 42p an hour on the earlier 27.67p/kWh cap. At today’s 26.32p those become 26p, 34p and 39p (our sums).
She measured up to 36 dB on maximum and thinks the advertised 34 dB is the low-setting figure. She found it quiet in use. Her complaints match Trusted Reviews: the touch buttons do not light up, the remote has to be pointed straight at the display from within about four metres, and the child lock can only be set on the heater itself. She would also have liked oscillation. Her verdict is that it is the best value for money on the market right now.

Who they are: Amazon reviews come from its customers, with a Verified Purchase badge where Amazon confirms the item was bought there at a normal price; it screens every review with machine learning and investigators, and Vine reviewers get free products, so check the badges.
Most Atom 316s in the UK are sold on Amazon, which blocks the tools we use, so we have not read the ratings ourselves. We are reporting what two third parties say about them. Both agree on 4.6 out of 5, but the sample size varies hugely. TechRadar’s February deal post says nearly 10,000 ratings, with a headline claiming over 3,000 five-star reviews, and does not name the model number. Latest Deals shows 589 ratings on the listing it tracked. Amazon often groups colour variants under one listing, which may explain the gap. Treat these as retailer ratings, not purchase-verified feedback.
The listings back up the spec the testers report: Power Heat, Eco and fan-only modes, a 5–35°C thermostat in 1°C steps, a 12-hour timer, a child lock and a mute option, tip-over and overheat protection, and V0 flame-retardant materials. The prices are useful too. Deals have repeatedly cut the £64.99 “was” price to £39.99–£42.48, so if you pay more than Dreo’s own £49.99 you have probably paid too much.

What holds up
- Very good heat output for its size: a bedroom up nearly 5°C in 30 minutes in a metered test.
- Eco mode used about a third of the full-power energy in a metered test.
- About 1.25 kg with a handle, easy to carry from room to room.
- Tip-over and overheat cut-offs, a child lock and an optional 24-hour auto-off.
- Full heat in under ten seconds from the ceramic element.
- £49.99 direct and often under £43 on deals.
What people complain about
- Touch buttons do not light up and are hard to read; “H1” looks like “HI”.
- The remote needs line of sight and works within about 4 m.
- No oscillation, so it only warms the area it points at.
- Louder than the claimed 34 dB at full power: testers measured 36 dB and 44 dB.
- It is still a 1.5 kW resistive heater: about 39p an hour flat out at the current cap (our sums).
- Only a 12-month warranty, and you need your proof of purchase.
Who it actually suits
Buy it if you want to warm one room for an hour or two, such as a home office, a cold bedroom before bed or a box room, without heating the whole house. That is when a fan heater saves money, as long as you use Eco and the timer. It is a good match for a Hive Thermostat Mini setup where the boiler is scheduled down and one room gets a boost. A smart plug such as the Tapo P110 will also show you exactly what it is costing. Its 13 A (2,990 W) rating leaves plenty of headroom for 1.5 kW, even under TP-Link’s advice to keep long-running loads to 80% of that. Plug it into a wall socket, never an extension lead.
Look elsewhere if you need background heat for hours every evening. An oil-filled radiator is silent and keeps radiating after its thermostat clicks off, though a bigger one draws more power flat out, so it is not automatically cheaper. Also skip it if you want voice or app control. The 316 has no smart features, and saying “Alexa, turn on the heater” to an Echo Dot Max only works through a smart plug, which switches the power but cannot change the heater’s mode.
What we could not check
- Amazon ratings at first hand. Amazon blocks our tools. The 4.6/5 and both sample sizes (nearly 10,000, and 589) come from TechRadar and Latest Deals, and neither names the exact variant.
- A UK retailer other than Dreo and Amazon. Currys’ listing at the URL once titled “Atom 316” now shows the Atom 416. We found no Argos, B&Q or Currys listing for the 316 itself.
- Noise. Dreo says 34 dB; Ideal Home measured 36 dB at max; Trusted Reviews measured 44 dB at 1 m. We cannot say which figure your unit will match.
- Thermostat range on Dreo’s UK page. It says only “1°C” control; the 5–35°C range comes from Trusted Reviews and retailer listings.
- Room size. The 20 m² rating comes from Ideal Home; Dreo’s UK page does not state one.
- UK warranty terms. The 12-month term is from Dreo’s general warranty page, which does not say which country it covers; Currys quotes one year for the sibling 416.
- Eco-mode cost. The 13p-an-hour figure is from one Trusted Reviews room; a colder or draughtier room will cost more.
- The videos. All three were confirmed by search listing, not by opening them. We could not see who made them or whether each shows a UK-plug unit.
- Long-term reliability. No source we could read reports on failures after the first winter.
