Looking for an efficient portable electric heater

matttaylor

Winter is here and I've typically heated my home using the gas central heating.
Earlier in the year though I had some solar panels installed and I'm thinking that even though it's bloomin cold outside if the sun's shining I can use this free energy to warm the house.

Does anybody have any advice on what kind of heater would make most efficient use of the energy.

Thanks,

Matt

All electric heaters have exactly the same efficiency, (100%), so simply buy the cheapest.
You don't say what the peak output of your system will be, but I doubt that it'll power a typical 2kW domestic heater.
Gas is approx one third of the cost per kWh if you are drawing from the grid.

Ah that's good to know. Thanks.
It's a 4KW system.

I plan to turn heaters things on until the meter starts turning.

Don't you get paid up to 16p/kWh for leccy you feed into the grid?

Why would you prefer to use this than pay less than 4p/kWh for gas?

Well I've an old meter and just get paid half what I generate whether I use it or not.

On domestic installs the input back to the grid is estimated at 50% of generation, not metered. So whatever you can use yourself direct is effectively free.

Exactly, that's why I want to make the most of it.
