Thanks danny_rosariorc! So far I have not seen in stores that I visited 16 liters, only 7, 12 and 14 liters. It happens that those of 14 liters already make me expensive to pay, so a larger one I assume must be very expensive. It is for a house with 2 bathrooms, one on each floor, about 64 m2
Thanks servimat1 and a doubt, if I put a gas thermos, it should be 120 liters, or a smaller one? It is for a house with 2 bathrooms, that is, one on each floor. What I noticed with the electric that for example in winter takes about 3 hours to warm up to get a shower, my girlfriend takes a shower and I can't take a bath to the touch, but I have to wait another hour to recover, I don't know if this is the same may happen with a 120 liter thermos, that delay in the initial load and the delay of one hour in recovery. More than anything the electric I want to change it because it consumes me 3 kw / h
