Exceptional Duration Built in high quality alloy bare heating element, the instant electric water heater is corrosion-resistant and acid-resistant; flowing water prevents limescale from building up, which prolongs its service lifespan. Review: Neat and compact - The unit works well and is beat and unibtrusive. I have it set to produce a temperature if 40°C at the handbasin. This is a comfortable temperature for my young grandchildren. The installation instructions were clear. The unit requires 4mm cable from the distribution box and a 32 Amp breaker and double pole switch for safety and isolation purposes. I am very pleased with it. Please note it is not designed to produce hot water for a shower but is great for a handbasin where a small amount of hot water is needed. Review: I wouldn't waste your time and money - So, it sounded like a good idea and simple fix for no hot water in the location of a new utility sink. Its 5.5kw so should be able to heat the water sufficiently considering the flow rate you get from other over sink hand instantaneous hand washers, that are around 3kw. To get the kind of heat you need from this, for example 40degrees, the water had to be dribbling out of the tap, so much so, the heater would then intermittently turn off as the flow was so little it though the tap was off... the air temp is around 10 degrees so nothing particularly low. It might be sufficient in the summer, but defo not the winter by any stretch. It will just have to be a storage tank which is slightly annoying as the sink is occasional use so will be a little wasteful for the time the water is being heated but not used. long story short. its not fit for purpose. ## Features - 【2S INSTANT HEATING & ENDLESS HOT WATER】- Turn on the water tap and endless hot water will come out within 2 seconds on demands when require, hence you will never run out of hot water and only pay for what you really use.

It was installed by a qualified electrician. When the heater is on all the lights in the house flicker?** A: Check your neutral connections, especially at the consumer unit. **Q: Does the water heater require a special unvented mixer tap?** A: Hi, the 5.5kW electric water heater doesn't need a special tap. You can connect it to two outlets. Hope it helps. Thermomate **Q: My bathroom fitters have told me this requires a pull cord type switch. Is that corect or can it be installed on a 13amp switched fused socket?** A: as far as I know it does not require a pull cord. due to its rating I do not think it will work from a 13 amp socket. I had a higher rated cable run. it will need an isolation switch. **Q: by how many degrees will it raise the temp working as a booster heater? Also does it switch off once the water feed is over a certain temperature** A: Hi, when the outlet water flow rate is up to 3L/min, the temperature will raise by 20-25 degrees. The water heater will be switched off automatically once the temperature is up to 60℃. Hope it helps. thermomate ## Customer Reviews ### ⭐⭐⭐⭐⭐ Neat and compact *by G***A on 23 December 2024* The unit works well and is beat and unibtrusive.
