## Questions & Answers

**Q: Could i use a timer to have the unit come on  and be ready for when i want it**
A: Dear Customer,

Thanks for your question. A timer cannot be used as the unit is designed to have a constant power supply.

At your disposal for further clarification.

Thank you.
Regards.

**Q: Can I set this product to heat up on a lower power - more slowly. 1kw or so would be ideal.**
A: Good Morning,

Thank you for your question. 

The regulation options on this product allow you to set a lower temperature, not a slower heating up. The front dial on this product allows you to choose the water temperature inside the tank. The ‘E’ economy setting marked on the dial would get you a temperature of about 55-60 °C. You can set the temperature lower than that if you prefer.

Kind Regards.

**Q: Is it insulater , how long would the water stay hot , would it keep topping the heat up**
A: Dear Customer,

Thank you for your question. The unit has a thermostatic control which keeps the water inside the cylinder at a set temperature and has an Insulation wrapped around the cylinder between it and the outer plastic shroud.

At your disposal for further clarification.

Thank you.
Regards.

**Q: Can this product be used with a water softener**
A: Dear Customer,

This is Not recommended, because of the different water PH, but still can be used with artificially softened water.
It needs to be serviced every 12 months and the sacrificial anode needs to be checked and replaced if necessary.

At your disposal for further doubts.

Thanks,
Regards.
