Electricty used by gas heating

First of all I don't want to get into a discussion but kiloWatt/hour is a measure of how much energy you're using per hour (kilowatts per hour). The total amount of electricity I have taken from the grid in a day is measured and charged in kilowatts. (e.g at 4 pm I was consuming 4 kwh but only until 4.30. Therefore I had consumed 2 kw)

@jrawle

day 1     Electric oven used for 1 hour, washing machine 40degree cycle, various low power lights on and off, hot water on for 20 minutes, NO HEATING ON……………     5.2 kW

day 2     Microwave for 4  minutes, hot water for 20 minutes, various low power lights on and off, HEATING ON   ……..  10.7 kW

Unfortunately you're very confused about the difference between power (kW) and energy (kWh), so that must cast some doubt on your conclusions.

Power doesn't depend on time.  A 100W bulb or 2kW two-bar fire is still 100W or 2kW respectively whether it's used for a minute, a couple of hours or a week.  However, the energy they use will vary according to the period involved, e.g. the two-bar fire will have used 4 kWh after two hours and 24kWh after 12 hours.

Thanks Victor

I can place the In-House Display right next to the boiler so I will be able to see both ar once (to see if boiler is firing)

A 10 second update on power consumption will be handy

Regarding pump ....  I read somewhere that they only kick in at the beginning of a "session" and then let gravity do the heavy lfting. Do you know if that is true?

Thanks Gerry1

Not confused at all... yesterday I consumed 11.4 kilowatts of power

But as I said "I don't want to get into a discussion"

 I know it's not true.

Very carefull measurements have been taken hourly, 4 times a ady, twice a day, daily, weekly,and monthly
They all show that when the heating is on we are using significantly more electricity


@jrawle
Nothing else being used, no electric heaters, no electric blankets etc etc
I will give you an example
day 1     Electric oven used for 1 hour, washing machine 40degree cycle, various low power lights on and off, hot water on for 20 minutes, NO HEATING ON……………     5.2 kW

day 2     Microwave for 4  minutes, hot water for 20 minutes, various low power lights on and off, HEATING ON   ……..  10.7 kW

smart meter  being installed next week !!!!


@zagfles  Thanks for reply.   Are you saying that freezer and fridge drawer significantly more in a colder room?

I appreciate not wanting to get into a discussion but your statement is incorrect.

kW(kilo/Watt) is a measure of the electricity you are using at any point in time. kWh(kilo/Watt/hour) is a measure of how much electricity you have used in a given time.

Thus an appliance using, say, a constant 2kW for 3 hours will have consumed 6kWh and you will be charged for 6kWh(6 units on a meter) - Look at your bill to see how you are charged.

Thanks Victor

So the pump will be running as long as demand from thermostat and therefore boiler firing ?

Completely confused, I'm afraid.  What you are claiming is the equivalent of "yesterday I drove 30 miles per hour".  What you consume and pay for is energy.  Power is the rate of energy consumption.  Remember those old filament light bulbs?  If you ran a 100 W light bulb for an hour you would have used 100 Wh in energy or 0.1 kWh.  If you ran the bulb for 3 hours you would consume 0.3 kWh, That's kiloWatt hours and not kiloWatts per hour.  Look on your bill if you don't believe it.

Our actual smart meter from British Gas gets the kW vs kWh thing wrong and displays misleading nonsense, so I don't blame OP for the confusion.

MikePh, ignore the "smart" display homepage and get to the actual meter reading. You might find this by digging through the display's menus or you might have to go to the meter itself. Take it at intervals with the heating off and on in order to get to the bottom of the strange usage.

@Cardew, appliances use POWER in WATTS, not kWh
