The continuous flow technology is electronically controlled and the compact design allows for an appeasing look.

A convenient safety feature that is available, as an optional extra, with the Bosch 4000S External continuous flow hot water heater is the temperature remote controller.

This handy feature allows you to pre-set your desired water temperatures for different wet areas within your home. This is convenience at its best as you will no longer need to constantly fiddle with your hot and cold taps to find your required water temperature – all you need to do is turn on your hot tap and once your pre-set temperature has been reached that is where it will stay.

With the use of mixer taps becoming increasingly popular the temperature remote controller also provides you with greater peace of mind.

Mixer taps can be an attractive fixture for toddlers, who can usually easily flick the tap on themselves. If your single mixer tap was left in the hot position when this happens hot water scalding is highly possible.

Pre-setting your hot water temperature to not allow it to reach these boiling temperatures greatly reduces the risks of hot water scalding, not only to the young, but also to the mobility impaired who cannot move out of hot waters harm in a fast fashion.

Is the Bosch 4000S External hot water heater right for my property?

If your home, or unit, does not have the required space for an internally installed hot water heater then you will need to look at an external system. A hot water heater is a major appliance purchase for your property and one that needs to be made correctly.

Choosing the wrong hot water heater for your property can cost you valuable dollars going forwards due to the hot water heater having to constantly work in overdrive to meet up with your hot water heating requirements. Or, more than likely, you will be having more cold showers than you bargained for!
