Hey,
I am looking for a new directly heated water cylinder for my home. What I am stuck on is the correct size of water cylinder.
Reading around online I can see suggestions of 30 to 45l per person, however it also states that a mains pressure shower system can use about 18 litres of water per minute. Which means 180 litres gone in 10 minutes. This makes a 400l tank seem small for even a 3 person house hold. I do not want the water going cold and then having to wait for it to heat up at any point during the day. Like wise I do not want the immersion heater on 24 /7. What would you guys suggest, does it really cost that much more to heat say a 500l tank vs a 300l tank? Once a tank is heated, how is it much cheaper just to maintain that heat via the tanks inbuilt thermostat?
Any input from plumbing experts?
