Perfect 35 Instant Undersink Instant Water Heater - 3.5KW
The latest in water heater design and manufacturing for reliability and durability
This small instant hot water heater uses simple electronics to control water flow and temperature providing a reliable and steady flow of water to a bathroom hand wash sink. It is non vented and has a minimum pressure requirement of 10psi or 0.7 bar.
This low wattage water heater provides hot or warm water for wash basins (if you are looking for a similar unit for a lightly used sink or en suite conversion alongside a pre-installed electric shower, we would recommend the more powerful Perfect 55 water heater that produces hotter water for the same flow rate and hotter water in general).
Designed with space saving in mind
The unit (with its small size) fits under sinks and takes up less space than traditional tank water heaters. If the sink or basin you are using is a distance from your central heating hot water source, we highly recommend using a Perfect water heater. This avoids the need for litres of water to run wastefully whilst you wait for hot water.
Instant water heaters do not need to needlessly heat up 10-15L of water for only 5L to be used. This unit only heats up the water as it runs through the unit, saving you energy and water compared to traditional undersink water heaters.
Compatible with any tap from ordinary through to single or monobloc taps (peak performance is found with a spray tap fitting)
Easy installation with flexible hoses and rubber gaskets for simple connection by a qualified plumber (not supplied)
- Not suitable for use with a shower or bath
