Huge Gas Usage of 32,000 kWh per year - Help !

If you have no need for hot water in the morning, just run it for a few hours in the evening. Looks like you have a pressurised hot water tank there, so leigonella will be a near zero risk. Running at 45-50°C shouldn't cause any problems.

When I have need of (really) hot water during the daytime, I'll boil a kettle - This has helped to reduce my gas consumption considerably.

We will hopefully have a heating engineer coming in the next week or so . 

Is he going to fit some more TRVs & give you a quote for a replacement, condensing boiler?

Are you supplying a power station?

Perhaps you could run your heating (radiators ON) for say 2 hours. Let us know what your gas consumption was for the 2 hours. 

Also give us the number of radiators in the house.

I have a VERY OLD boiler, that uses a pilot light. I have calculated the pilot light burns about 9 KWH a day, as a reference point. We are in the process of selling our house, where the new owners will no doubt upgrade the heating system.

Just did some calcs - 4 'normal' showers (300 litres) of hot water will need about 12kwh, 85% boiler efficiency = 14kwh per day so that is probably your target - plus any hot water you use for washing up etc.
