“ The Xtrafast is a new generation of combi providing hot water to the tap in just 5 seconds. That means less water and gas being used waiting to get usable hot water, making it more environmentally friendly. Also allows hot water to be run at a stable temperature „
Made by Saunier Duval in Nantes, NW France. Very well made, very user friendly and good looking, though big!Extremely good value, 5 years without a hitch and the micro-accumalator means instant hot water. Many features.Some of these still around as S-D Isofast or G-W Xtrafast. Same animal - S-D ones usually cheaper - just the badge is different!!Buy one! Soon..
