"Combi boiler" (https://en.wikipedia.org/wiki/Tankless_water_heating#Combina...). Are these not common elsewhere in the world? We got rid of our old tank and central heating system and replaced it with a combi a few years ago. We simultaneously gained lots of extra space - a whole walk-in cupboard and a lot of loft space - while gaining a new device which requires hundreds of pounds of replacement parts every year. Really the most unreliable of technologies, but also very convenient when it's working.
