A Compact Instant Water Heater
This compact water heater is ideal when you’re tight on space. It fits neatly under your sink, where it’s easy to hide out of sight, and provides hot water to any sink or wash basin. If an immersion heater or water boiler isn’t practical – for example, in a small, isolated workshop or shed – this instant water heater is the perfect solution.
Dramatically Reduces Waste Energy
As it doesn’t store hot water at any point, this instant water heater dramatically reduces the amount of energy you’ll waste. It means you’ll only ever heat up water as you use it, and it’ll stop using energy as soon as you shut your tap off.
Ideal for Sheds, Workshops, and Other Areas Without Hot Water
For some places, it’s not always practical to plumb in hot water. Fitting boilers and hot water tanks often requires invasive and expensive building and plumbing work, and if you have a shed or garage that needs hot water, it might not seem worth it. This instant water heater is small and simple to install, fitting neatly beneath your sink. This means it can be installed almost anywhere with minimal cost and effort.
Provides Hot Water at a Fast Flow Rate
When used under sinks and wash basins, it provides hotter water at a faster flow rate than most other instant water heaters. It can provide 1.5 litres of water a minute at a temperature of 62 degrees. Faster flow rates will be slightly cooler, but the 5kW heating element inside the unit means it can give warm water at flow rates of up to 3 litres a minute.
Permanent 6.5 Bar Water Pressure
This water heater pumps water at a perfectly even 6.5 bar water pressure, providing an even flow rate even if you fully open your taps.
Designed to Use with Any Tap
As it fits into the pipework below your sink, you can use this water heater with any tap. This gives you the freedom to use it with any sink or wash basin.
