What's your Heating and Hot Water Schedules?

I have set our water at 8am till 8.25 and then 3pm till 3.25 that's with 3 of us. We share a bath butt anything after 2 baths your struggling to have hot water in the evening

Obviously depends on your boiler/system, but six hours of hot water seems excessive although presumably it isn't heating all the time. I would have thought an hour in the morning for hot water sufficient if you are showering only. Heating seems to come on early and go off early in the afternoon/evening but again depends on your working hours etc.

Don't have schedule as combi boiler and 2nd shower is electric. 

How much does it cost per day currently with that setup ?
We have a combi boiler but we're using approx £11 per day gas and electric to have the heating on 20.5 degrees from 8am-10pm and 4 ppl having showers every day.
As already mentioned above it can be better to keep heating at a constant temperature rather than to have the heating coming on and off for long periods as it takes a long time to heat back up which costs more than short blips through the day to keep the constant temperature set (edited)

We have tankless. 18 degrees 24/7. If I set it to go down to 16 overnight, it takes ages and uses just as much gas to get it back up to tempature. Costing about £4 a day in mild winter, and £10 when it went -8.

Only takes 20mins to heat up a water tank depending on your boiler and will stay hot for a few hours

Heating when needed generally 30min in the mornings and on again for 15 twice for drying clothes.

Hot water is on demand as we have a combi2 bed flat for 3

That does seem a long time for the hot water to be on; do you have a cylinder thermostat? If so set it to 55-60C and regardless of the timings it should shut off when the temp is reached. (Should not be any lower than that, to keep legionella bacteria at bay and no need really to have it any higher than that I'd say). If you don't have one then look into getting one fitted (you might be able to do this yourself depending on how comfortable you are with wiring it in). Also ensure your tank is well insulated.

I'm not sure whether the hot water being at the same time as the heating makes any difference. If they're on together the hot water coming from the boiler will (or should) be split between the two so effectively taking twice as long to do each job, whereas if you have them at different times then each will get 100% so I don't think you'd see a massive difference either way. (as long as all the valves are working correctly and diverting to each side as appropriate)

Heating set to 16
Water 30 mins in the morning and On-demand if required in the evening. Tank set to 60c. (edited)

I'm on White meter electric and I used to get my off peak hot water boost through the night, I was happy enough to let it boost every night but since the price hikes what I've now taken to doing is just switching the boost heater off and using the hot water up until it goes cold and only then boosting it so that's normally 3 days worth of hot water. I have also cut out baths completely in favour of showers.

Combi boiler so no water schedule. Hot water is set to 50 degrees on the boiler which gives a nice hot shower. It was set a bit higher than that because my OH loves an absolutely boiling bath, but she has those so rarely it can just be turned up when needed.

Heating goes on at 07:30 (half an hour before alarms go off) and stays on at 15 degrees until 22:00. Quite often gets turned up a bit more than that in the evenings mind you and sometimes during the day/weekends, but I find it fine for WFH (office is usually a few degrees warmer than the room the thermostat is in)
Peak gas usage according to Flow was £9.31 on the worst day during the cold snap, but closer to £3/£4 recently with the milder weather.

Interesting thread. As a tip anyone with an electric shower can switch there hot water off. If I need hot water in the kitchen I will boil the kettle.
