Almost Embarrassed To Ask

[Flashheart]

But not too embarrassed....

Got one of those digital electricity meters but there is no info on it. Is 1 unit equivalent to 1kW?

I'll get my coat......

My one is a watt per hour meter

One unit of electricity = 1kWh = 1kW consumed for one hour!

Thanks Matthew, I thought it probably was. Just looking at buying an ecofan (fan with peltier cell that sits on top of woodburner and turns when woodburner is hot - free electricity) but at £102 I can run my normal electric fan 24hrs a day for almost 5yrs for the same price in electricity.

Theoretically then, using it for 4 hrs a night means I will probably die before I spend the same amount.

It really isn't worth trying to save the planet sometimes!

Um, a fan that sits on the woodburner?

So you need to make the surface hot for the fan to cool you down?

I think the fan is meant to circulate the warm air around the room.

I had one of those woodburner stoves and it was so efficient we had to open the windows to let the heat out

With a bit of patience you could make a thermopile generator to power the fan. This may be more effective than a Peltier effect generator. It is a fairly simple task, low cost materials but time consuming to assemble.

There are commercially available ones and they generate a significant amount of power.

Thanks a lot Bernard, that is exactly what I have been looking for. I have the same problem as everyone with a woodburner - it gets too hot! I am considering putting some ducting up through the register plate so I can vent some of the air upstairs but in trials I have done there is little airflow. I thought some kind of fan would do the trick and if it can be powered for free then I'm all for it.

Time to make a thermo-electric generator. This will be a laugh!

A heat exchanger to generate electricity and sell it back to the National Grid? There's loads of those eg http://www.e-energy-enterprise.com/...rgy-enterprise/images/eee-system-overview.pdf

Yet another good idea - not sure about the 20 ft shipping container that they say contains all the electrical generating equipment

One unit of electricity = 1kWh = 1kW consumed for one hour!

Or 3.6MW consumed for 1 second! (Replace the service fuse with a nail and your tails might actually last that long)


















Disclaimer - your safety may go down as well as up if you replace your service fuse with a nail.

Care to elaborate? It of course assumes that you get as far as surviving inserting said nail, which would be far from certain![/b]

Hmm...

1unit = 1kWh = 3.6MJ

(since 1 watt-hour = 1 Joule)

 

[bernardgreen]

Hmm...

1unit = 1kWh = 3.6MJ

(since 1 watt-hour = 1 Joule)

Or maybe 1 Joule = 1 watt-second
