Hydronic Heating

Posts Tagged ‘Passive Solar Heating’

a) Is it a crazy idea to put a hot water bottle in it at night? Or pour hot water in a bucket at the bottom? (It doesn’t get enough direct sun for passive solar heating.) Should I do it as soon as the sun goes down, or later when I go to bed?

b) Should I insulate the floor? It’s standing on concrete paving stones. Will the thermal mass help or just make it colder?

It’s this kind of greenhouse; small and plastic. I’ve got a fleece cover for it but it’s still too cold at night.

We want to replace a low-quality hollow-core door in our 1899 cottage with an antique solid exterior-rated door with 10 panes of beveled glass but are concerned about energy-efficiency.

We live in San Francisco and almost never use heating and never use air conditioning. We both agree that the door with the panes would be much more attractive.

I think that the glass-paned door could provide us with passive solar heating through the panes (we don’t have any windows on that side of the house), but my sweetie thinks that the heat loss from the panes would negate any solar heating effect.

Is the hollow-core door more energy-efficient than the solid door with glass? And if so, how much more? Or is weatherstripping more of an issue?

Thanks!
