Duronic Bathroom Wall Heater BFH20

If you have a bathroom without a radiator, or perhaps you do have one and it’s just not enough to warm up the room to your liking, then this bathroom wall heater will be perfect for you.

There is nothing worse than getting undressed for a bath or shower in a cold room or coming out of a warm bath into the cold air. Well, at Duronic we have found the ideal solution for you!

From the moment you switch on this wall heater, warm air will start to blow out from the downflow vent and quickly warm up the area around it. After a few minutes, the room will be much warmer and cosy, so you will no longer dread walking into the cold bathroom.

Thanks to its customisable heat settings, this electric heater can be used on full power (2000W) or half power (1000W). In addition to this, the BFH20 fan heater boasts many more features to make your life easier…

PLEASE NOTE: We advise users to not plug the heater into an extension lead or power adapter as the heater is too powerful for it. Using an extension lead or adapter with this heater is a fire hazard and may cause damage to the heater or the user. Additionally, an electrical extension lead is not safe to use in a bathroom environment.

    It didn’t take long for my electrician to install this. It’d a great heater and although it uses 2kwh of energy within 5 minutes of being on the room is to temp. I haven’t used the controls to set a timer as I only use the bathroom once a day so I turn it on when I’m in and turn it off when I’m done. This didn’t come with a remote control or instructions but I was sent instructions via email through the amazon store if I needed them. The only downside is like all fan heaters it’s a bit loud and it runs for 1 minute cold before switching itself off when the room reaches temp

    What remote control? None with my heater.
    Not needed though as it is easy to operate and heats the bathroom quickly

    I installed it in my bathroom and I am very satisfied. Heats up fast, has two modes of heating which helps to save energy.

    I am satisfied

    We bought this to replace our existing heater and were pleased with the speed at which it heated the shower room. It is very adaptable and adjusts the temperature during the operating time. If it reaches the set temperature it switches off for 30 secs and then comes back on. There is a 30sec cool down period after it is switched off but the air it circulates is still warm. We have not used the timer function. Would recommend as a efficient alternative to the others on the marke

    Was it suppose to have a remote control – sadden no manual – otherwise it’s a good fire for the Bathroom – energy efficient – glad I did not have to programme it though – quite challenging for the electrician though!

    Replacement bathroom heater. Excellent to use as a simple fan heater (we do not need the programming features). Just need to remember to hoover out the vents at the back regularly – before the dust builds up. Vents are accessed by (turning of power from isolator switch before) undoing top screw.

    I would just like to mention how great they were in communication- my first heater didn’t work unfortunately, but they replied so quickly, sent free returns labels and sent a new one out within days! And the new one is marvellous! HIGHLY RECOMMEND! 5*

    I use it in a mid size bathroom. It warms up the bathroom in less than 5 minutes. I use this rather than already installed oil radiator.

    Probably designed for a commercial setting. Works to a set of high and low temperature times during the day. Customisable programme. However, there is no manual switch to get the bathroom toasty before a bath.

    Arrived on time. Well packaged. Great little heater. We have hard wood floors so it is a little noisy but when we put a rug under it not so. Love that you can programme it which is really easy.

    A little louder than expected, compared to other floor type fan heaters I have but nothing ridiculous. Programmability is a bonus and fit our needs perfectly so big plus.

    Heats up the small bathroom very quickly and cycles to maintain temperature well. Needs a quick manual override in order to heat the bathroom when it’s outside of the planned time

    Great value

    Golden Review Award: 4 From Our UsersI really like this heater. I have mounted it high on the wall in my bathroom as a replacement for an old storage heater.

    The heat output is good and it warms the room in a few minutes to the selected temperature. I love that you can set a timer or use one of the inbuilt programmes to keep your room warm when you need it. The fan does make a noise when it is on but it is not too bad.

    The only slight issue is that when the heater reaches the required temperature and shuts off the residual heat warms the unit so it thinks the room is warmer than it is for about ten or fifteen minutes until it cools off again. This can leave the room a few degrees colder than the set temperature so to allow for this I have set the thermostat a couple of degrees higher. It is not an ideal solution but it is inevitable that this will happen with this type of heater.

    So overall this is a really good heater. It is very controllable and produces a good amount of heat.

    Golden Review Award: 2 From Our UsersPurchased for an outdoor toilet. The heat is instant so the small room is heated in seconds. Will buy again when required.

    Golden Review Award: 3 From Our UsersGreat heater! Much better quality than the standard bathroom fan downflows. It’s very powerful which makes it a little noisy but that’s ok as there are lots of programmable or pre programmed timer modes eg on all day or just weekends. Check your sizes and was easy to fit to my existing bathroom suitable electrical fitting (came with a UK standard plug which I removed in 15 seconds). Actually looking forward to winter so my bathroom will be like a Turkish bath 🙂

    Golden Review Award: 4 From Our UsersThe heater looks very smart although due it being summer, I have only tested the heater and used it briefly to assist with drying the newly plastered ceiling. The instructions for programming are easy to follow, and there are plenty of available options for different days of the week. I won’t say that I’m looking forward to the colder weather, but I’m confident the bathroom won’t be cold first thing in the morning owing to this purchase. The fitting was easy if you are upgrading from an existing fan heater.

    Golden Review Award: 8 From Our UsersEasy installation and easy operations. Clear manual with instructions for programming – only had a look at pre-programmed setting but had no need for using them so far (maybe in the winter time) It’s only been in use for 2 weeks and so far it’s working good. Heats the bathroom quickly. You can choose what temperature you want to achieve and when turned on it shows the current temperature too. It’s a bit quieter than my previous heater – bonus there. Let’s hope it will last longer. One feature that isn’t documented anywhere – after you turn it off to what’s called standby mode it runs the fan only for about 1 minute so no heat output during this time – just fan. I believe it’s the same after it reaches programmed temperature – heater switches off and fan runs for about a minute – unless the temperature will drop during that time.
