watts and Kwh whats the diffrerence

TotalDespair

Hi

Ive got the chance of purchasing a free standing coal effect fire (Dimplex Sprinbourne), to help supplement my storage heaters.

The heat settings on the fire are 1800 watt or 2000watt (per hour??)

My electric costs me with Npowers E7 tariff

26.2p for the first 2 hrs then 14.9p there after and my night rate is 4.9p in the evening rate

I will be out most of the day making my storage heaters well cooled down by the time I return by 5.30pm most evenings so would be relying heavily on this fan heater type coal effect stove effect fire to supplement my heating.
So before I purchase this could someone please tell me the likly hourly rate this would cost to run per hour and how to convert wattage to Kwh.

Sorry if this sounds a bit muddled up but hey I am blonde lol and thats my excuse( TD ducks from all the verbal :mad::mad: from other blondes)

Any help would be most gratefully received.

I live in a one bedroomed D energy rated ground floor flat with single brick wall construction and badly fitting sash windows and badly fitting doors as the Landlord says antique doors think thatsan excuse lol haha he is too mean to replace them lol so this fire would be belting the heat out for at least 4 hrs per evening and Im not even going to think about all day at weekends if we have a winter like last year.

Many thanks

1,000W = 1Kw

1800W = 1.8Kw

2000W = 2Kw

So at 14.9p per Kw/h your heater will cost approx 30Pence per hour, for each hour it is on FULL. It is likely controlled by a thermostat though, so will cost a little less to run once the room has warmed up.

No it is actually 1000 Watt or 2000 Watt

No it is 26.2p for the first 728 kWh used each year (calculated pro rata on your bills). The 4.9p rate is for seven hours cheap rate during the night NOT the evening e.g. 1:00AM till 8:00AM (depends on your region).

A heater rated at 1000 Watt (1 kW), operating for one hour uses one kWh of energy - one unit. Therefore on the 1000 Watt setting, it would cost 14.9p per hour and on the 2000 Watt setting it would cost 29.8p per hour to run.

This is a simple two setting flame effect fan heater with no thermostat.

Thank you Andy_WSM and expresso for the quick and explanatory answer to my question, very very much appreciated .

I have now worked out the cost of running this heater and thank you expresso for pointing out my E7 rate hours through the night, I will check with nPower what exactley these are, although another resident said to me this morning it was the local electricity distributor that chose the times of the E7 and not my electric supplier who is correct please.
this is a minefield to likkle old me but once again thank so much for your explanation and imput has helped me no end..

Yes it is "the local electricity distributor that chose the times of the E7 and not my electric supplier".

That is expensive daytime electricity, which is unfortunately what has become associated with E7 tariffs. Not sure what else you can do in rented property, but if you get very little benefit from the storage heaters during the hours you are there, maybe do some sums for the hours you need heating and hot water using the best non E7 tariff and consider panel heaters in the rooms.

I disagree, if you have a time switched meter it is the meter operator who sets the switching time on the meter based on what he has been told to do by your supplier.

If you have a tele switched meter then this is controlled remotely and is dynamic.

Wouldn't want to disagree if there are different methods out there, but this is what most suppliers put in their notes.
From the EDF ratecard:
* Economy 7
Night kWh will be supplied for a total of 7 hours between 10pm and 8am (actual times set by the local network operator) and these will be charged at the Night kWh rate. All other kWh will be charged at the day kWh rateV.

Not all will switch on at the same time, imagine all of those storage heaters coming on at once. Two neighbours I know, one comes on at 11.00 and one at 11.30.
