Heidenfeld vs Könighaus infrared heater
Updated: 22 October 2026
Heidenfeld vs Könighaus infrared heater is the question you reach when the HF-HP panel you wanted is not in an amazon.co.uk basket and a Könighaus Smart Dual is. They are different companies. A Smart Dual can do some of the same jobs, a slim electric panel with a thermostat in a dry room, and it cannot wear a Heidenfeld badge or inherit Heidenfeld warranty wording. This page stays on that gap. Patio tubes and halogen towers are on the [Heidenfeld infrared heater comparison](/hub/heating/heidenfeld-infrared-heater). Prices are GBP from listings read on 20 October 2026. Peter F. checked them. A qualifying purchase can earn us a commission at no extra cost to you. This is not a lab test.

What a Heidenfeld HF-HP panel is meant to be
Heidenfeld sells infrared panels through continental retailers under HF-HP style model names: wall and ceiling formats, sometimes picture or mirror faces, with thermostat options and long warranty language on those retail pages, often IP20 rather than a patio rating. That is the product a UK shopper pictures when they type the brand. It is not a row in this comparison. Research on 20 October 2026 found no in-stock Heidenfeld panel on amazon.co.uk. The only Heidenfeld infrared listing in the search was the outdoor IH100 tripod heater, and that page was unavailable. The IH100 is not an HF-HP and should not be used as a stand-in for a wall panel.
Euro prices on continental shops are not amazon.co.uk prices. Importing an HF-HP adds a plug question and a warranty that may be honoured only by the shop you bought from. A Könighaus box does not inherit a Heidenfeld promise because both heaters are flat and white.
What the Könighaus Smart Dual listings actually include
Two Könighaus panels sit in this batch. The Smart Dual 450 W is about £99.90, 70 × 70 × 1.3 cm and 5 kg, with feet, a wall kit, a remote, Wi-Fi, a towel rail and IP44 printed on the listing. Amazon UK shows 3.8 out of 5 from 582 reviews. Reviewers who use it under a desk or on one floor say the spot warms within a couple of minutes. Several warn it is not for a large or open-plan room. The maximum temperature setting in the spec table is 40 °C. Owners often call the surface too hot to touch, including the back, and some do not trust the thermostat or the app as a reading for the whole room. One review describes a carton that arrived without instructions, feet or the remote.
The Smart Dual 800 W is about £169.90, 90 × 90 × 1.3 cm and 9 kg, with the same feet, remote, Wi-Fi, towel holder and IP44 line, and 4.1 from 159 reviews. The maximum setting is 70 °C. No square metres are printed, and one review said 800 W still suited a small room. A bullet about mounting the 450 W panel conflicts with the 800 W spec table, so check the live page. Origin on both listings is China. At an illustrative 26 p/kWh the 450 W panel is about 12 p an hour and the 800 W about 21 p. The hourly sum is on the running cost page. The Energy Saving Trust’s point still applies: electricity costs several times gas for the same energy, so neither panel replaces a boiler.
Where the features line up and where they do not
Both are electric infrared panels rather than glowing patio tubes, so line of sight matters: government user research on infrared heat is about comfort in the beam, not about warming the room behind you. Both sides of the market talk about thermostats. Könighaus puts the thermostat, the remote and Wi-Fi in the Smart Dual carton, which is more control in the box than a basic panel that expects you to add a switch. Heidenfeld’s retail descriptions also offer thermostat control on HF-HP models. Having an app on one brand does not mean the other brand’s app, account or schedule will load. You would be starting again.
IP ratings are not aligned. Könighaus prints IP44 and names the bathroom among uses. Heidenfeld panel pages in this research are associated with IP20 language, which is a lower ingress mark and still not a bathroom design. Neither number is a BS 7671 zone diagram. IP44 does not by itself allow a portable or plug-in panel in zone 1. Fixed bathroom wiring in England and Wales is Part P work. If a bathroom was your reason for preferring one brand’s IP line, stop and ask a registered electrician before you treat either listing as permission.
The towel rail is a rail on a hot panel, and the feet let you stand the 450 W model without drilling. Coverage is the shared hole: Könighaus prints no square metres, and continental HF-HP size names are not a UK test you can paste onto the Smart Dual. Warranty is the sharpest gap. Heidenfeld’s retail story is a long manufacturer-style guarantee. The Könighaus files in this extract do not state an equivalent multi-year manufacturer warranty in the technical table. Your UK rights against the amazon.co.uk seller still exist under the Consumer Rights Act 2015. That is not the same document as a ten-year Heidenfeld guarantee, and it does not transfer a German brand promise onto a Könighaus serial number.
Who should buy the Smart Dual and who should wait
Buy the 450 W Smart Dual if you want a small occupied spot, feet plus an app, and a price under £100, and you have read the 3.8 star line. The comparison marks that 450 W panel as best value in the wider set. Open-plan rooms are outside what those reviewers describe. Buy the 800 W Smart Dual if you have measured the wall for a 90 cm square and about £169.90 is acceptable. Confirm 800 W on the live spec table.
Wait for Heidenfeld if the badge, a named HF-HP size, or the long warranty from a Heidenfeld seller is the point of the purchase. A Könighaus panel will not become those things after delivery. If the job is a gazebo, use an outdoor row on the main table instead. For a small room and an app this week, the recommendation is the Könighaus 450 W, unless the room is clearly too big for 450 W and the 800 W face fits. One pick per job, including the patio rows, is on the best Heidenfeld infrared heater page.
Common questions
Is Könighaus made by Heidenfeld?
No. They are separate brands. The Smart Dual listings name Könighaus and give China as the origin. Heidenfeld’s HF-HP range is a different catalogue, mostly seen on continental retail sites in this research, and it was not in stock as a panel on amazon.co.uk on 20 October 2026. Similar shape does not mean the same factory or the same guarantee.
Which Heidenfeld model matches the 450 W Smart Dual?
There is no official pairing. The 450 W Smart Dual is 70 × 70 cm and does not print a square-metre band. Heidenfeld HF-HP names on other shops refer to that maker’s own sizes and wattages. Match a future Heidenfeld listing by watts, centimetres and mount, not by assuming HF-HP and Smart Dual are twins. Until that listing exists on amazon.co.uk, you are comparing a present Könighaus panel with an absent Heidenfeld one.
Do both have app control?
The Könighaus Smart Dual 450 W and 800 W listings include Wi-Fi, a remote and a thermostat. Heidenfeld retail descriptions offer thermostats on HF-HP models, but that is not this app and not a shared account. If you already own Heidenfeld controls, a Smart Dual will not join them. Read the app name on the Könighaus live page, and treat room-wide temperature claims with the scepticism the 450 W reviews already show.
Is IP44 on Könighaus enough for a bathroom?
The listing prints IP44 and mentions the bathroom. That is not a BS 7671 zone drawing and not a Part P certificate. Portable or plug-in heaters are not the usual answer for zone 1, where fixed equipment and an electrician belong. Heidenfeld’s IP20-style panel language is not a stronger bathroom claim. Ask a registered electrician before you drill in a wet room.
Can I compare UK prices directly?
You can compare the two Könighaus rows with each other: about £99.90 for 450 W and about £169.90 for 800 W, both on amazon.co.uk in this set. You cannot turn a euro HF-HP price into a fair pound comparison without the UK listing. When a Heidenfeld panel appears on amazon.co.uk, use that GBP price, the plug type and the seller’s returns policy. Until then, the Smart Dual price is the one you can pay here.
Does the Heidenfeld warranty transfer to Könighaus?
No. A warranty follows the brand and the seller who offered it. Consumer Rights Act 2015 rights against a UK Amazon seller apply to the Könighaus unit you buy. They are not a ten-year Heidenfeld guarantee. The Könighaus technical tables in this extract do not print an equivalent long warranty line.
