  • Small Compact, Easy to Install Water Heater ideal for hand wash basins!
  • Undersink vented units are attractive because installation is very simple and no specialist accessories are needed.
  • Including a vented mixer tap rather than a spout and cold water tap.
  • The fact that the Handyflow Slimline Vented Undersink comes as a complete package and the user does not need to purchase a separate cold tap makes it an economic alternative to the Handyflow Vented Oversink. The vented mixer tap supplied with the water heater comes with flexible hose for ease of installation. 
  • It is normal for the vented hot water tap to drip slightly during the heating cycle, caused by the water expanding as it heats up. This occurs with all vented water heaters.   
  • Full Specification: 
  • 5L Capacity - POWER 2.0kW 
  • complete with vented tap and hose 
  • external temperature control 
  • 2kw element 
  • white corrosion proof case 
  • safety re-settable thermal cut out 
  • suitable for single outlet only 
  • wall bracket included for fast installation

Bought this as an under workbench water heater for my workshop. Delivery was fast considering most of the country was covered in snow. Installation was straightforward helped by clear instructions. Works beautifully.

Frequently asked questions

Would this be sufficient to service 2 hand basins ?
This is for use on 1 hand basin.
Is it connected to the Mains water supply.
Yes this unit has to be connected to the mains water.
Is there a minimun water pressure to be able to operate the HandyFlow ?
The minimun pressure is 1.0 bar
I have an under sink water heater (unvented) The tap permanently drips. called out a plumber who said it should drip !! Is this correct as it is not economical if losing water 24/7
This water heater is vented and it is perfectly normal for a vented tap to drip during the heat up process. This is caused by the water expanding as it heats up. 
Hi I have bought several of these now. Is it possible to change the washers? Thank you Michael.
There is no reason to change the washers. If you are thinking of changing the washers to stop the tap dripping, this is not necessary. The vented tap is designed to drip, as a means of releasing the pressure build up when water is heated.
