Have a nice new electrical greenhouse heater. Its set to automatically

So as to calculate power use and hence cost of greenhouse heating anyone
know of a good inexpensive system of recording the duration the heater was
actually on?
Thanks

The meter in your cupboard? Do you really need it so precise? Why not
just compare your next electricity bill with the one for the
corresponding period last year?
If you're serious about energy saving, forget the built in thermostat
and get a proper one. Google Two Wests & Elliot for suitable ones.
