JungleSeeds Greenhouse Heat Requirement Calculator

This section calculates the Power required to heat a greenhouse or conservatory structure in winter based on your input parameters. This calculation is intended as a guide for estimation purposes only . Other factors like wind shear heat loss can also significantly increase heating requirements.
Please enter here the square feet surface area of the structure. If you do not have these calculations, please go to our Structure Surface Area Calculator further down this Page.		sqft
Please enter here the minimum outside winter night time temperature in Centigrade that you want to protect		Min °C
Please enter here the minimum inside structure temperature in Centigrade that you want to maintain during the minimum outside temperature that you entered above.		Max °C
Please enter here the appropriate heat loss factor that equates to your structure from the table below.		Heat Factor
	Please hit calculate - This number is the Power that you need in Watts to achieve the desired temperature uplift. Please divide by 1000 for Kilowatts	Watts



Heat Loss Factor Parameters - Please chose the one that most represents your Structure
