hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

I have a little cabin in my backyard. Recently, i have dug out a 1000 Watt air heater and installed in the cabin.

I like to find out how long i need to run the heater to warm up to the room temperature of 21 ºC from the ambient of 12 ºC. Either the heater needs to be bigger or let it run longer to heat up the room

I initially start the calculation with this equation Q = m Cp delta T. Re-arrange the equation and it becomes m = Q / (Cp * delta T). Once i have find the mass flow rate, i know the volume of the room and the density of the air. I can calculate the time right?

However, one of my main concern is about the insulation and the infiltration which changes the time to heat up the room right? but that equation does not state any U value or R value. so... did i do something wrong or use the wrong equation?

Thanks
