106KWh per day Gas consumption?

[EdMarsh]

Too much.? My elderly (95) Mum lives on her own in a small detached 2 bed , with gas combi boiler 5 years old. Her most recent gas bill with actual meter readings says she has used 39000 KwH in the last 12 months, thats more than 106 per day, Shes at home all day. Boiler timer is set on from 7am to 10pm, with thermostat set to around 24.
Boiler also heats water on demand.
Can this be right? Any suggestions other than the usual insulation and clsoe doors options?? thanks

Anywhere near 17,000 kw/hrs can be considered average use, according to ofgem. Your mums is a little high, although her operating times are lengthy.
It may pay to get the system and boiler checked, and also review what rooms are heated and insulate as much as you can.

heeelllooo and welcome EdMarsh

put another jumper on and reduce to 21/22 degrees will save a fortune

if you have thermostaic radiator valves turn them down to 18 in other rooms not used much during the day and 15 in rooms not used

24 ° C is likely to have the boiler on most of the time during the programmed 15 hours, even though it will modulate down. There is also DHW usage to consider. As posted, the high programmed temperature and the length of time the heating is on will amount to well above average gas consumption for the size of house.

My elderly mum also used to turn the heating up, and put the gas fire on as well, even in summer.

Sadly extravagant usage does result in high bills.

If you take accurate meter readings more often, you will be able to identify patterns of daily usuage.

I've done some simple calcs, the boiler is on 15 hours a day at a set point of 24'c in cold weather it is unlikely that 24'c will ever be achieved

106 Kw'h per day divided by 15 hours = 7.0 Kw/h which is about right for what the system is being asked to do.

Improving the thermal insulation of the property, turning down rads in un-used rooms and reducing the set point to say 21'c will all help reduce costs

thanks all for your comments, very helpful. Ed

The average US house takes 6 BTU per square foot per Heating Degree Day, and 100,000 BTUs = 29.3 kwh. My leaky old house comes in at 11 and a tight new house comes in at 2.

If you can find temperature data and insulation data for a typical house in your area of similar construction you can gauge how reasonable this is.
