How many gas unit to run central heating

sazale

I was wondering if anyone knew roughly how many units it takes per hour to run a combi condenser boiler a rated with 7 radiators. I would appreciate any help as currently using 100 units per week and only have central heating on gas. everything else is electric. Thanks.

Depends on so many factors - how big your house is, how well insulated, how warm you have the rooms and how many you use, how long you have the heating on for, how much HW you use.

7 Radiators doesn't mean much as they can vary in size so much.

You can't really calculate how many units per hour it will use.

Assuming you have a Metric Meter(most are) a unit is approx 11.5kWh so approx 1,150kWh a week(say £25-£30) That would normally, at this time of the year, heat a large property.
