Not really, and for the rest I must (regretfully) say it is rather badly written.
Biggest dose of heat is not what I would say. The unit of heat is Joules.
A Watt is a Joule per second.
A kWh is a kilowatt times hour which makes it Joules again (which you probably know).
I hope the title is a typo.
