Passive Solar Greenhouse Case Studies: http://bit.ly/2ERJKtY
In this video I talk about thermal mass and passive solar greenhouses. In our greenhouse we use a Rocket Mass Heater and it works great.
Thermal mass is crucial to your success if you want to extend seasons. Water’s often talked about as the ultimate thermal mass, but it can freeze and make a mess. Even though they have a quarter of the thermal capacity of water, I’m a fan of stone, used concrete or cob – you don’t have to worry about them during the winter.
If you are using water as thermal mass, use 8-12 L of water per square foot of glazing. If you’re using stone, concrete or cob, go with 40-60 kg per square foot.
