Two weeks ago i had my old boiler (old gravity fed system) replaced with a worcester bosch 37 cdi and have noticed that my gas usage has increased from approx 2 units to 5 units per day.
The settings on the thermostat are still the same, 21 degrees from 8.00am to 10.00pm and the 16 during the night. The shower is electric and there has not been an increase in hot water usage.
The house is a standard 3 bed semi.
I thought that a new condesnsing boiler would reduce the amount of gas used.
Any help or advice will be much appreciated.
