Depth around 25mm **Q: Can I use it outdoor?** A: It is not waterproof, so short answer is a definite “NO” (as indicated by its description “Indoor”; there is no mention of IP certification). For external use, it would have to have an IP rating (such as IPXY, where Y=4, or 5, or 6, e.g., IP44 at a minimum for rain protection, and IP46 for higher water protection – Google it). **Q: Would this work for electric underfloor heating?** A: Yes it will be fine as long as the underfloor heating load is not above 13 amps. Most underfloor heating is well below this as it needs to be cost effective, but just check. **Q: Can the transparent cover be left off ?** A: It’s probably OK, but the cover is to stop ingress of dust/ dirt which if left off completely might impair the unit operation ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable and easy-to-use mechanical timer. *by Y***R on 16 February 2026* This HBN 24-hour immersion heater timer works exactly as expected and is very straightforward to set up.

Good value and suitable for everyday household use. ### ⭐⭐⭐⭐⭐ 16amp timer unit. *by M***Y on 29 July 2026* Perfect item, easy to install has it comes with instructions, very easy to set the control times, definitely recommend this timer. ### ⭐⭐⭐⭐ Relatively simple to install and easy to use *by J***H on 11 December 2022* Purchased so that I could add timer functionality to my bathroom electric towel rails as they were currently on simple on/off switches, which were a pain to remember to turn on and off when needed. I am not an electrician but have installed similar timers and switches before, if unsure hire a professional. Items arrived quickly (bought two, one for each bathroom) and the timer was in small cardboard packaging, no plastic, good for recycling. Box contained the timer, some clear instructions (the same as on the product page) and 2 spare backplate screws to screw to the back box. Installation was a process of removing the old switch leaving the original back box in place. I then unscrewed the backplate from the timer switch and screwed that in to the back box. Yes the screws are fairly tight, and you will need a small Phillips head screw driver to get in the recesses. Remember the orientation when you install it as it needs to match with the timer. Luckily for me the old switch had clearly labeled wiring and it was a case of replicating that on the new switch. However, and this is really where the 1 point is deducted, there are no earthing terminators, which meant that I had to use a separate wiring connector block to connect the earthing wires (see photo for type). Not a big problem, but it may require a trip out to the shops to get them (bought mine in Wilko), and there is enough space left in the back box to store it. It's an additional few £'s if you don't have them already. My wires were solid core, so fitting and screwing the timer switch on to the back box was a bit of a pain, but otherwise straightforward. I suggest partially screwing the bottom screw first so you can see the alignment, then the top screw. Timer itself works fine so far. The guide says to push the timer pins "in" for the times you want it to turn on is correct, it's just how you interpret the word "in". I assume it is meant to be taken as pushing them down and "in" as they become more recessed than when they are "out". The timer took me a few seconds to understand, basically the outer time selection dial is 24 hours, and the inner clock is 12 hours, both on one dial, so you rotate it to the correct AM/PM time. The current 24 hour time is shown by an arrow at the 2 o'clock position on the dial. The inner "clock" is slightly redundant I think as you can just focus on the outer 24 hour dial time. It's good that it allows control over a 24 hour day, each "pin" is a 15 minute segment and simple to set up morning and evening on times. I have tested it and it works on the timer when set in the middle position on the red switch, as well as just switching it to on or off. The orange light at the bottom left signifies when the switch is "on", it's not very bright but in a dark room it may be distracting. The clear plastic cover clips on with 3 clips, the cover needs slight pressure on each clip to remove, which should keep young children from removing it, but it's by no means secure. Overall a good purchase, both items were equally well built so no variance that I could see, I would buy them again if the need arose. ## Frequently Bought Together - HBN 24 Hour Indoor Energy Saving Mechanical Immersion Heater Segment Timer Switch with Waterproof Cover, White, 16 Amps - Schneider Electric Lisse White Moulded - Single Surface Pattress Box, 16 mm Deep, GGBL9116S, White - Schneider Electric Ultimate White Moulded - Single Surface Pattress Box, 25 mm Deep, GU9125, White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/60272140-24-hour-indoor-energy-saving-mechanical-immersion-heater-segment-timer](https://www.desertcart.tn/products/60272140-24-hour-indoor-energy-saving-mechanical-immersion-heater-segment-timer) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-26*
