To date I've been switching on and off manually, when I remember! I bought this unit to take out the manual element and it is fantastic. It is easy to programme and instructions were very clear, works the same as most electronic programmers, taking only a few minutes to set up. It does protrude quite a bit from the wall box but that's not an issue for me where it is located. When I wired it up I had to add an electrical joint for the earth wires as there is none fitted to this unit, which wasn't a problem but did make it a bit tight to fit in a standard wall box. Don't really know why there isn't an earth point fitted to the terminal block as standard which would have saved me rummaging around for a suitable terminal block myself, but not an issue really. Had it all wired in and operational in about 45 minutes and am delighted with the silent operation. The display light goes off after a few seconds of not pressing buttons and the red power light stays on all the time but is not obtrusive. The green light comes on to indicate when power is being supplied to the towel rail. Overall a nice piece of kit that does just what it says on the package. Highly recommended and will be fitting another when I revamp my main bathroom in due course. Review: This timer is great! Fitted it to control the heater element in ... - This timer is great! Fitted it to control the heater element in my 23 year daughter hot water tank. The reason for fitting was she kept leaving the heater on for hours and forgetting to tun it off. You can imagine the electricity bills which were high for someone living on their own. Fitted the timer and set it to come on for an hour in the morning and the same just before she came home in the evening this has now reduced the electricity bill by over 50% in the first month. The other advantage is this timer has a boost button were you can switch the heater on at any time just to quickly heat up the water and it will then automatically switch off after an 1 hour or you could set it for 2 hours if needed, so it does not matter if you forget.. Instructions that came with the heater the print is very small and difficult to read. I when onto the internet found the instructions the the Timeguard web site which made things a lot easier. The only extra purchase which was needed to install this timer was a deep switch box as the standard switch box is to shallow to allow room for the wiring and connections. Very easy to install and set timer and is now proving its worth in savings. ## Features - 4 on/4 off easy-set programme periods per day, 28 on/28 off programmes per week - Extra large 'easy view' Screen with blue LED backlighting - Red LED 'mains on' And green LED 'output' Indicators for easy viewing - 16(4)A load rating ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BJIB97K | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 21,232 in DIY & Tools ( See Top 100 in DIY & Tools ) 38 in Timers | | Colour | White | | Customer Reviews | 4.5 4.5 out of 5 stars (831) | | Date First Available | 1 Jan. 2010 | | Display style | LED | | Finish | Smooth | | Included Components | Heater Timeswitch | | Item Package Quantity | 1 | | Item Weight | 171 g | | Item model number | NTT03 | | Manufacturer | Timeguard | | Material | Plastic | | Part Number | NTT03 | | Plug profile | Tabletop | | Power Source | Corded Electric | | Product Dimensions | 11.7 x 16.9 x 23.2 cm; 171.1 g | | Size | 12 | | Style | Compact | | Voltage | 230 Volts | ## Product Details - **Brand:** Timeguard - **Model name:** Current - **Product dimensions:** 10D x 10W x 10H centimetres - **Controller type:** Hand Control - **Special feature:** Programmable - **Colour:** White - **Specific uses for product:** Boiler - **Included components:** Heater Timeswitch - **Power source:** Corded Electric - **Item weight:** 0.17 Kilograms ## Images ![Timeguard NTT03 24-Hour/7-Day Compact Electronic Immersion Heater Timeswitch,White - Image 1](https://m.media-amazon.com/images/I/41XA45fQ9IL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very high quality and easy to set up: highly recommended *by G***K on 30 July 2015* I have a heated towel rail which is run on central heating when on but in summer uses an electrical element.

As our oil fired water heater died, we are entirely reliant on the immersion heater for hot water at the moment. However as it was fitted with an ordinary on/off switch there would be little or no hot water first thing in the morning and it was far too easy to forget to turn it off, which soon starts costing a fortune. The water heater is now programmed to come on for a half hour before anyone gets up (and while the power is cheaper) and to turn off at several times throughout the day (in case it somehow gets turned on and forgotten). We can also get a 1 or 2 hour 'boost' on demand and not worry about forgetting to turn it off. The NTT03 fits into a standard pattress box, but it might be a bit of a squeeze if you have a lot of excess wire. There is no Earth connector on this switch, so you might want to have some wire nuts on hand in order to securely connect the earth wires together if there is no earth terminal in the pattress box. Wiring took ~15-20 minutes, including removing the old switch. The terminals are clearly labeled and the instructions straightforward. The only caveat is that the screws holding the bezel in place have _very_ shallow phillips heads (none of my crosspoints could actually get any grip on them). I had to resort to a small flathead screwdriver to get them in and out or risk stripping the head. The instructions for setting up the timer are straightforward (pretty much identical to every other unit of this sort that I have ever used) As an added bonus, The display is backlit while in use so it's easy to see what you are doing. Unit has a built in rechargeable battery so it should keep settings for a good while if it loses mains power or gets turned off at the breaker/isolator. Straight forward installation, Straightforward operation. Does what it's supposed to. I docked a star for the needlessly cheap bezel screws which could have easily been stripped making the whole process a lot more difficult. Note. that this unit NTT03 is set up 'out of the box' for an immersion heater, the included instructions suggested that the NTT04 'general purpose' switch would also be suitable but might need additional adjustments during installation. ## Frequently Bought Together - Timeguard NTT03 24-Hour/7-Day Compact Electronic Immersion Heater Timeswitch,White - Schneider Electric Lisse Gang Surface Pattress, 25 mm - Timeguard FST24 24 Hour Fused Spur Timeswitch Storage/Immersion Heater --- ## 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.kg/products/48057978-timeguard-ntt03-24-hour-7-day-compact-electronic-immersion-heater](https://www.desertcart.kg/products/48057978-timeguard-ntt03-24-hour-7-day-compact-electronic-immersion-heater) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-05-06*
