I think this is what you are looking for

Well said 
If you use hot water everyday and a lot, then getting a dispenser is really useful

For my family, we seldom use hot water at home as we brew our coffee in the office with a 1.5L kettle.

For Low usage, not worth getting bcoz :
1. Water Dispensers require maintenance due to the calcium build up and etc inside the machine & storage tank which you need to get technicians to clean it. Servicing will cost you $$ unless you purchase the machine with a rental scheme.

2. The machine will use more electricity as it will need to reheat and keep the water hot, if you use very little hot water you will be wasting $$ on electricity and also elderly says it is not healthy to keep on boiling the same water over and over again.
(Note : The machine doenst boil 24hours non-stop, when temperature drop til certain degree only it will reheat)

For low usage, just get a 1L kettle, only take awhile to boil compared to the conventional 5L kettle. Boil the water only when you need it to get fresh & high quality water for consumption.

Aquaphor does not manufacture water dispenser but i could order a korean dispenser to be coupled together with Aquaphor Crystal Eco.
