## Features

- EFFICIENT FAST ELECTRIC WALL HEATER: The moment you switch on the BFH21 wall heater hot air starts to blow out and warm up the surrounding room. You can choose between using the heater on half power (1000W) or full power (2000W), depending on your preference and how quickly you want the room to heat up. This heater helps you to save energy thanks to its programmable time modes and the open window detection function
- 5 PROGRAMMABLE MODES AND TIMER: Customise the pre-set modes to ensure your bathroom is kept at the temperature you like when you want it. You may only want the heater on in the mornings, or evenings or perhaps even just weekends. Schedule and save up to 5 different modes. The reverse timer function allows the user to set a countdown time for automatic switch off, for instance, set for 2 hours and the heater will emit heat for 2 hours and then switch off
- OPEN WINDOW DETECTION TO SAVE ENERGY: Unique to this model, the BFH21 wall mounted heater has a Window Open Detection feature that detects when either a window or door is open and consequently allowing the heat to dissipate too quickly. IF the heater detects that despite blowing out consistent hot air the room's temperature isn't increasing properly, it will automatically switch off to save itself power and from overworking
- MADE ESPECIALLY FOR BATHROOMS: Rated IP24, this heater is waterproof and splashproof so it is ideal for bathrooms and similar environments. Please note that we recommend that this heater is installed at a height no lower than 120cm from the floor for safety purposes

## Questions & Answers

**Q: What is the length of the lead, from unit to plug?**
A: I wired mine in and didn't use the plug - so can't tell anymore. Maybe 1.5m

**Q: Can the lead be replaced with a longer one?**
A: The answer is yes, but by removing the existing plug and using a JUNESUN 13A InLine Connector Box 3 Terminal Join Flex Cable Wire Mains Electrical Joiner as sold by Amazon, then adding desired cable length.   That is what I did successfully.   The connector box can then be pushed together to form a safe connection

**Q: duronic wall mounted bathroom heater can youhelp how to set date and time**
A: If you go into the Duronic Website and at the top there is a section for different appliances when that open there is is section at the top User Manuals which will open the manual you require hop this helps

**Q: Will programming be stored if there is a power outage?**
A: I don’t know.  It is a complex heater that seems well made and is powerful. I have not learned how to program it after a couple of weeks.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Convenient control and good heat output
*by K***E on 19 March 2024*

Bought for the small bathroom of our holiday home. Installation was no problem, if you take time to mark and then ensure you double check the mounting screw positions. Heater output is sufficient for where we have it, and the thermostat works well enough. We had no reason to set the timer; it warms the bathroom within minutes of turning it on (this was while using it in the Alps at Xmas!).Looks good fitted to a wall, and the downward blower helps distribute the warm air more quickly to where it's needed, rather than it going straight out and up to the ceiling.Some complained that it's noisy. For us it's fine, but if you have it fitted in a living space (living room, kitchen) then I guess it might become more noticeable. For the duration of being in the bathroom taking a shower or whatever, the noise level wasn't an issue at all. Time will tell though; if the bearing on the fan starts to go, then it might get noisy. We'll see. For now I can recommend it.

### ⭐⭐⭐⭐⭐ very good heater
*by A***R on 27 October 2023*

what I liked was when fitted in the bathroom and put in use it has made it more pleasant when put to use, what I dislike was thre was (no instuctions to fit it) also it didn't come a box, only in a plastic bag, this isn't right, so in my mind I say has someone had the heater before & returned it to you, please explain, I await your answer, I spend a lot of money with youover the years,& I don't think it's,I await your answer soonest

### ⭐⭐⭐⭐ Functional but a bit complex.
*by J***H on 12 May 2025*

Works well and has lots of functions but a bit bulky, too complex with poor instructions to help. But, to be fair, it keeps frost at bay and quickly heats up a fitness room when needed
