"Different issues over the pond" Well depending on which pond you're talking about, we're actually on the same side :) " my kettle can draw 3kW :)" True, you have some special circumstances in your country. You'd still be better off with a boiling water tap, the cost of which (even when amortized over only a few years) is the same as using a kettle (when accounting for all costs - lost energy, water, installation costs etc). So for somebody implementing this in the UK, they'd have to budget for an additional 1500 pound up front cost - which has the potential to turn into a cost saver after 5-10 years (probably closer to 5, depending on how fast energy costs will rise - which I think is fair to expect will be at a higher-than-linear rate).
