How much heat you will need will depend on the outside temperature, and whether you just want to keep the greenhouse just frost-free or a bit warmer.
Has the heater got a thermostat?

as has been said it depends on many things just go online and see what heater would be best for you an electric heater very good choice if you can afford to run it because I've used electric heaters in the past and when the electricity bill arrived  i thought i was paying for the street and yes the greenhouse was lovely and warm and the plants loved the heat no sure if the wife was in favour of using the electric greenhouse heater though that soon went

so I went with a gas heater using bottled gas that to was quite expensive and i failed to lag the greenhouse with bubble wrap that mite have helped conserve the heat then there's the good old paraffin that i found a bit messy and seemed to attract white fly

it is a minefield finding the best greenhouse heater because whatever you go for its going to cost you that's why i packed up trying to heat our greenhouses because it got to dam expensive to heat them  i would think very carefully about what its going to cost you before making your mind up and yes a thermostat would be worth considering anyway good luck with what you buy
