What’s in an image? Sometimes quite a lot, more than meets the eye.
I’m posting an image every two days (or as often as I can). A photo, an image from the internet, a diagram or a map. Whatever takes my fancy.
The Montalto Estate in County Down had an extensive fruit and vegetable garden to supply the house year round with freshly harvested crops. Greenhouses were an important feature, providing out-of-season crops and exotic fruits like pineapples and citrus. These greenhouses needed heating in the winter months and this was supplied by wide-bore cast iron pipes below the plant benches.
The remains of some of these pipes are visible in the photo. They usually ran in pairs; there were no circulating pumps, instead the boiler would be below ground in a stokehole and the hot water would rise and flow by gravity acting on the changes in density. Hot water rose in the system and the returning pipes contained cooler, denser water that flowed down, re-entered the boiler and warmed up again.
I remember greenhouse heating systems just like this from my childhood, my father had a role in the family business at that time, a nursery with greenhouses full of cuttings and seedlings and houseplants that needed heating during the winter. There was a wonderful smell of greenery, the pipes were always warm, yet never too hot to touch, delicate maidenhair ferns grew wild around the pipework below the benches and these were allowed to remain because the fronds were always useful in making bouquets and buttonholes for sale in the shop in town, or for weddings and other occasions. Even on cold, frosty days you’d want to take off your coat, hat and gloves if you went into a greenhouse!
Modern glasshouses are very different, they have oil or gas fired systems controlled automatically on demand by thermostats, and the heat may be distributed by water pipes or by fan-blown air circulation.
