- This instant under sink water heater quickly and efficiently provides hot water for a wash basin with hotter water delivered than the Perfect 35 water heater.
- Water runs through the unit and is heated up using the latest in heating element technology for efficient, instant supply
- Traditional tank type water heaters have to heat litres of water before supplying hot water to you. So for washing your hands, you may use up to 10 litres of cold water before the hot water arrives. With an instant water heater, the water is supplied hot instantaneously cutting down on wasted water and associated bills.
- If your basin is a distance from your central heating water source, we highly recommend installing a perfect water heater
- Suitable for use with any taps from single to monobloc, with peak performance found with spray fittings
- The unit will not supply a shower or bath with water.
- 19.6 amps fuse needed
- Minimum water pressure required 10psi or 0.7bar

Good instructions..easily fitted ..seems a good quality water heater.. perfect for undersink water heating, saving me lots of money as I now don't have to heat a full tank of water for occasional use

Had purchased before cheaper under sink heater, this started to leak within six months, got a new one under garuantee this also started to leak within three months,
Decided then to get hopefully a better more expensive heater, twice the price of previous one, on opening package immediately felt it was sturdier and better made.
Easy to fit, instructions ok, works well better hot water output from previous one, so far so good, but it is early days!
