The new ensuite we are planning will have longer pipes runs from the HW cylinder than the current main bathroom, which takes ages it seems.
(House is an L shape, kitchen/utility on one leg, with the HW tank above and just a bit along from the kitchen in a room which is technically a bathroom, but not used as such - though is to be refitted and used again. The ensuite and current house bathroom, are on the other bit of the L . If I was starting from scratch no I wouldn't start from here, but i'm not, so I am)
So, considering putting an additional HW cylinder for the ensuite.
Going for a bit of luxury, (the room is much bigger than ur old bathrrom in the old house) We will have a decent pumped shower (no, I'm not interested in a electric shower), and a nice big bath (I like having the space for a proper ). So maximum draw in normal use is likely to be a couple of consecutive showers, or a bath fill.
How big a tank do you reckon for this? My gut feeling is that the marginal cost of a bigger tank, or heating a bit more water is such that erring on the bigger side is a good idea.
Space for the tank is not an issue, we ahve a cupboard in the room with planty of space
