Providing your home with endless hot water is no easy task, especially if you have a large family (or teenage girls). With the installation of an instant water heater, however, you will be able to take advantage of a seemingly never-ending tank that is also energy efficient. Three Phase This type of instantaneous electric hot water system is best suited to homes with multiple outlets (more than one bathroom). They are quiet energy efficient, which is good for both the environment and your hip pocket, and are incredibly easy to install. There is also no need for ventilation, safe trays or flues, so they can be installed wherever you have the room. Single Phase This type of system is best suited to homes with much smaller water demands (a single bathroom). They are also quite energy efficient, allowing you to do your bit for the environment without draining your bank account, and are also very easy to install. Like three phase units, there is no need for ventilation, safe trays or flues and they can fit in even smaller spaces. Point of Use This type of system is suitable for any home, as they are installed at the outlet itself, but they are considered ideal for isolated sinks (the laundry, kitchen and bathroom). These units also don’t require ventilation, safe trays or flues, and will ensure that there are no long wait times for warm water.
