We bought this as a Sabbath hot water urn - but it's so big that we can use it for hot water all week with just a topoff. All the cheaper ones we purchased failed in some way during the return period or shortly thereafter. With pump pots, the air pump typically fails within the first year and none of the vendors provide replacement parts. We're not permitted by our religious laws to use the electric pumps on Sabbath, so the urn is then useless, which is why we opted for the spigot design. The Garvee will boil a full pot of water in about 5 minutes. It keeps water at about 185 and starts reheating instantly after topping off. A few notes: 1. The sides are not as cool as with some other double-walled urns, but not too hot to touch. The top, as usual with these, is not insulated at all so we keep a folded towel on top to retain heat. 2. We do not use this for coffee, so we cannot comment on the percolator function. 3. The sight glass is graduated for the percolator function so some interpolation is required for hot water use. So far so good - the best urn we've had in 20 years.
