byecold Infrared Panel Heater Built-in Thermostat, LED Light Ceiling Mounted Radiators Remote Control with Timer, Energy Efficient Far Infrared Heater Panel Heating - 840W

Have put 2 if the 800w panels with LED lights, in a 6m x 3m kitchen, it has freed up walls by removing the radiator.The panels each have a control panel which can be positioned anywhere in the room, these allow lighting and heating to be controlled separately.When switched on, you can feel the radiant heat within minutes, timer options are available and the heating is very effective and looks great on the ceiling, and provide great lighting. As they become active very quickly I only turn on when working in the kitchen... keeping the running costs down.As a 800w devise they are not designed to be wired into lighting fittings but require properly wiring into the electric ring.

Bought this as our Triton Body Dryer finally caved.Infrared was a new concept. Fitted to ceiling no problem. Best to make a screw template using the cardboard from the box.A slow build up to desired heat hence the need of a timer thermostat. Initially fiddly to set but once I remembered to switch Timer to ON it's all good. The LED lights are cute and use less power than 6 halogen downlighters.Early days but so far so good.It's not a robust item so handle with care. The several footprints on the box courtesy of couriers was disconcerting!

Decent infrared heater, I installed the 840w in the ceiling on one the bedrooms (3.0m x 3.7m) in November. Saves a lot of space and has a nice dimmable led light included.There was an issue with the delivery because the company does not use Amazon delivery service, it gave the panel to Evri that could not deliver it because of the size (!!!!), and this resulted in a lot of hassle for me and 20+ days delay on the estimated delivery day. Not the best start.The panel itself heats up realtively quickly, but I don't share the hype about infrared being superior to conventional heaters. It depends of course to what it is compared to, in my case I have a 750w storage heater in the other bedroom (same size) and to be honest the storage heater performs better in almost all aspects. Some details:1) infrared does not consume less. It consumes the same if not more, as in you can leave the ir panel on non-stop for hours and it does not reach above 21-22°c. The storage heater takes about 2 hours to heat up the same room and from there it stays on about 50% of the time. I can also tell from the smart meter that the ir panel consumes sensibly more. Probably if you compare it to an obsolete/cheap electric heater then yes, it's cheaper to run. Otherwise it's same consumption or worse.2) It does not feel like standing under the sun, it feels like standing in front of a woodburning stove and personally I don't like it. I much prefer the traditional heating.3) The panel only really heats the area right in front of the heating surface. If you install it in the ceiling, the heat does not reach even close to the walls and the corners of the room which are left a lot colder. For bigger rooms I would definitely suggest several smaller units rather than a single large one.4) The installation is straight forward. It is always tricky to install things on the ceiling, this was no exception. I managed in the expected time and the remote control setup was also very easy. I was worried about the battery life as when they run out you loose the programming but mine have been installed in November and they still show full capacity so I think they will last a very long time.5) I have the feel that this panels would perform better on hard floor rather than carpets due to the nature of IR heating, but I can't be quite sure. I will install one more in the kitchen next winter, to see if it is better with laminate flooring.All in all, I would have give it 4 stars on overall quality and performance, because in the end it works and heats albeit not as effectively as I hoped, it still takes the same time as my other heater to warm up the room. I dropped another star due to the delivery issue.

I slightly regret not buying a 'smart' WiFi controlled version of this device; my partner found a cheaper and seemingly better version after I'd installed this one. On the whole, it's probably the right one, though, as we needed one for the ceiling and the built-in light means that we were able to remove the old pendant light.I won't dwell on the practical aspects, as more erudite reviewers than I have already done that.Being a software engineer I have been able to convert this into a 'smart' device so that we can ask our assistant (smart speaker) to turn the light on/off. I did this by analysing and replicating the radio signal the remote control sends out when you press certain buttons. Strangely, the controller sends the same signal for on or off, meaning that the light and heat are controlled by two 'toggles' in effect. This complicates matters as it's easy for the smart speaker to go out of step with the light. E.g. when you turn off all devices in your home, it might turn the light back on. I'd like to fit a sensor to tell the computer I use whether or not it's already on.If you want to have a go yourself, here are some technical pointers:The remote control uses the popular 433MHz band: channel 35 (433.925MHz). This is the one used by inexpensive 433MHz transmitter/receiver modules (compatible with Arduino etc.). Don't do what I did and assume the smaller one is the receiver!There's no point me providing the full coding as I suspect that each command incorporates a unique serial number anyway, but it seems that a stream of about 416 bits. I arranged these into 32-bit numbers, sending m.s.b. first. My heater's light toggle command starts: 0xAAA00145, 0x11554555. It looks like they're using Manchester coding (or something like it as there are 3 or more clear bits at times... quite what it is, I don't know, but simply resending all the bits does the trick).Each bit lasts for 500uS (i.e. toggling bits would result in a 1kHz square wave) and I simply bit-banged these out to the 433MHz transmitter having first disabled interrupts.Next, it was a question of the smart-home set-up. For this I used Sinric Pro; they let you set up three devices for free and practically write the code for you. I used Arduino IDE to compile it for an ESP32 and it works fine.For the light sensor (i.e. to determine whether the light is actually on), I'm thinking of exploiting the fact that, unless the light is totally off or full brightness, you can detect a 7.8kHz pulsing from the LEDs. So, maybe the trick is to ensure the light is at least partially dim (by sending the dim light command) then looking for the characteristic pulsing. That would give you some confidence that you're not just picking up stray light.Hopefully the above will save you a few hours! Good luck :-)

Only good thing is the dimming on light. Does not heat a small area

I like the innovation of this light and heater for bathroom ceiling once the installation and controls sorted which required some additional instruction and then it's been OK to use and control.

Looks like a nice product but no accurate measurement of the actual unit itself led to it being returned as it was too big. The small square unit measures 705mm x 705mm.
