## Description

HBN 24 Hour Indoor Energy Saving Mechanical Immersion Heater Segment Timer Switch with Waterproof Cover, White, 16 Amps : desertcart.co.uk: DIY & Tools

Review: Reliable and easy-to-use mechanical timer. - This HBN 24-hour immersion heater timer works exactly as expected and is very straightforward to set up. The mechanical segments are easy to adjust, allowing precise control over on/off times, which is useful for managing energy usage. The unit feels solid and well built, and the waterproof cover is a helpful feature for added protection in utility or boiler areas. Once configured, the timer operates consistently and switches the load reliably. Overall, a dependable and practical timer switch that helps automate heating schedules and improve energy efficiency. Good value and suitable for everyday household use.
Review: did the job - I used this to control outdoor lighting, as the timer needs power itself you can’t just run the switch wires from the lighting to it as it needs a neutral, it was very easy to fit although I used a very thin patress and needed to dress back where the screws fit as the mounting plate fouled a little but this may have been the make of the patress, overall very pleased (wanted something basic and easy to use) will be buying another for the next project.

## Questions & Answers

**Q: How deep does the mounting box need to be please - in mm?**
A: It's surface mounted not inset. 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

### ⭐⭐⭐⭐ Inexpensive Timer - works well once installed.
*by C***. on 23 November 2022*

This timer was already inexpensive before the Black Friday sale brought the price down to just over £10 - very good value. The format is a fairly conventional analogue/mechanical timer - simple to set-up or re-set, especially after a power cut. The instructions are fairly clear, with a good wiring diagram. There are 2 reasons I have only given a 4 star rating - first, as others have commented, the instructions have the "time on" set by pushing the timer segments inwards - they need to be pushed outwards - fairly easily sorted, with a bit of experimentation. Secondly, a less easily solved and more annoying issue - the 2 screws which secure the unit to its mounting plate, need to be removed so as to attach the timer to a pattress or back box. These screws are buried at the bottom of deep recesses at 2 of the units corners, and are accessed from the front. Unscrewing these cross-head type screws was for me a major annoyance. The access only allows for a narrow screwdriver shaft and the screws seem to have been inserted over enthusiastically with a powerful mechanical driver. This meant the "cross notch" in the screw head was burred, which prevented ANY purchase with a typical cross head or Phillips screwdriver. The entire unit cannot be properly mounted without the removal of these screws ! I finally resorted to drilling them out and inserting fresh self-tapping screws. Once the unit could be separated, and thus correctly mounted, the remaining installation was straightforward, and to date the timer seems to be working fine. This unscrewing problem may be a "one-off", but it could have resulted in the return of what is basically a strongly made and good value unit.
