## Questions & Answers

**Q: In order to have hot water in the kitchen sink and bathroom sink, do I need to install two of these? Many Thanks**
A: One for each should be ok I have 1 under the kitchen sink yit is fine

**Q: What size water fittings/adapters are supplied and or needed ?**
A: I fitted these a while ago and can quite remember. What I can remember is I used 15mm JGSpeed fit hose and standard fittings for it. 
Not much help but I hope it’s of use. The device comes with a selection of fitments.

**Q: Is that tap suitable to heat the water in a mobile/portable sink that’s not plumbed in just using electric?**
A: The water would need to be pumped to the heater and you would also need 220 volts.
But in theory yes it should work fine.

**Q: Does this unit need a pump or is one built in?**
A: no it does not need a pump as it is a direct feed  from  the cold water supply

## Customer Reviews

### ⭐⭐⭐⭐⭐ 7KW one drives a shower fine
*by K***E on 6 August 2023*

Used to drive a shower in an already fully integrated bathroom, replacing an old hot water tank fed from the loft.Fitted as close to the shower tap as possible and only wired in the hot supply, capping off the cold. Then you just turn it up to the maximum on the temperature dial and control the temperature using the flow dial (fast/slow).The result is perfectly usable and as good as any electric shower I have ever used.

### ⭐⭐⭐⭐ Delivered promptly
*by M***O on 18 December 2022*

I bought this to save energy heating litres of water by the combi boiler to reach the bathrooms miles away, so you end up washing hands in cold water anyway and all the hot in the pipes is wasted. In that respect, this will be a great saving, as it does heat quickly to warm enough for hand and face washing, but the flow rate is necessarily slow. At 3.75 kW, it seemed to blow a 13amp fused spur and cut out, so it may need a higher rated connection. We did that and it works. We've plumbed it in a way that can easily switch back to boiler if necessary, or f energy prices ever revert to something like normal.

### ⭐ Dangerous
*by A***N on 8 August 2023*

This was a temporary solution to replace a unvented under sink water heater which split and leaked everywhere. As working in commercial building maintenance it was easy for me to fit but at first leaked at the joints. This is not a good product, the pressure is bad, just dribbles out, Electrically the main issue is it melts the 16Amp switched fused spur and the cable super heats. I would recommend to avoid buying this product.
