Why Choose Us?

At Grunwerg we have a long history of supplying top-end vacuumware such as flasks, cafetieres, teapots and serving dishes, and we only ever work with the very best of manufacturers to ensure top quality products.

We have been working with stainless steel for over 70 years and it is a material that we have a lot of confidence and experience with so you can be well assured that our steel, dual-walled vacuum kettles are durable and well molded. 

Having undergone rigorous testing, our Vektra kettles have proven us right in believing that they are a worthwhile, economical investment. In brief, the tests carried out were to estimate; the time it takes to boil a full kettle, the noise created as said kettle boils, heat retention every hour for four hours and the amount of energy used to boil the kettle at full capacity. 

It was observed, throughout every test, that the Vektra kettles (Grunwerg) beat their competitors on each test. For more in-depth information, please see the link below.
