So last couple of months we've averaged 11kWh of Gas per day and 10kWh of electricity per day. Somewhat disappointed that this is that high given that our only gas usage would be for our system boiler to heat our 300L hot water tank to about 56C and every single lightbulb in the house is a low energy LED (bar one actually, in the kids bathroom - which is a halogen). I haven't insulated the tank yet, so will do that this month, but I've at least insulated the pipes. Electricity seems high, though I do work from home and we do a lot of laundry as we have two young kids and we watch a lot of TV. How's your energy usage at the moment? Particularly interested to hear from those who also have a gas heated hot water tank. I've now turned the thermostat on the tank down to about 53C to see what difference this makes. It's difficult to know the exact temp it's set to as the analogue dial shows 45C and 65C and then two equally spaced increments in between which should be equivalent to 51.67 and 58.33.

My plumber is telling me I need to allow 100L per person per day (implying 400L tank), whereas my architect is telling me I should go for 300L because plumbers always over-specify. Our water usage pattern is as follows: The way things will be in the immediate future: we run one bath for both kids to share every evening - the bath we will have requires approx 125L of (blended water); we each shower for about 12-15 minutes in a fairly good rain shower, usually in the evening but occasionally in the morning. No idea of water usage for that. once or twice a week, I run a large bath (250L of blended water required), instead of the daily shower. In the future, things for us adults will stay the same but I imagine the kids will eventually want to bathe separately, so that will be an extra 125L per day of blended water and when they are teenagers I'm assuming showering will replace bathing. So what indirect unvented tank should I go for: 300L or 400L? Struggling to understand how much I should plan to heat on an everyday basis and how often I should use the "extra hour" feature. For example, would a 300L tank suffice as long as for my once or twice weekly giant bath I used the extra hour feature. How does washing up impact the above? We mostly use a dishwasher, but there are still large pans to do in the sink etc.
