Great for high temperatures/not recommended for 175F temperature
on December 19, 2011
I own this particular model along with a couple CD-LCC models and other boilers. Hand down, Zojirushi is the best for having large amount of hot water ready at home or small coffee shops.
Please note that CV-DYC40 was mainly designed for holding water at 208F and 195F. The unit is designed to be plugged in 24/7 and refilled as needed. Note that a whole gallon of water is contained in an extremely well insulated container while the boiler heats to 212F every single time one adds water! It takes about 2hrs for the insulated units to cool to 175F, which is painfully slow. If you insist on holding water at 175F, I suggest getting a non-insulated CD-LCC model. A workaround for CV-DYC40 is to boil about 2/3 of the water and top off with cold water.
The battery function is very nice as you can take the boiler anywhere in the house, coffee shop, outdoors for parties, catering etc. If you own a small coffee shop and are looking for a boiler/kettle for americanos and hot chocolate consider that this boiler is very slow (30-40min to boil a 4 liters) and you may end up using this boiler as more of a 'fancy' carafe, still using a regular kettle to boil water.
Lastly, for those of you who are tea aficionados, part of the tea flavor comes from oxidation. As the water sits in the boiler at, say, 195F or 208F oxygen and other gases escape which may lead to some teas tasting slightly different. But, hey! If you can't tell a difference then who cares?
