Electricity costs a lot in Europe. Years ago I’d heard the cost was generally six times as high as in the USA. As a result, the Europeans are more careful about the way they use energy. They try not to waste it.
Many Irish homes use electric storage heat. The system mimics adobe construction of the southwestern United States. It uses “thermal mass” (in the form of bricks) to soak up heat when it’s free (from the desert sun) or cheaper (at night when purchased from the utility company in Ireland).
The bricks hold the heat until the air on the outside gets colder than they are, and then they release the heat they are holding into the air to warm it.
I’ve posted photos of Keith, the maintenance guy for my apartment building, checking one of my electric storage heaters. They’re a bit difficult to get started at the beginning of the winter season. Mine needed extra attention because a toddler who used to live in this apartment stuffed small plastic items into the heating units. Keith had to clean them out.
In any case, I hope this technology keeps getting used and improved, as it’s a system that makes a lot of sense environmentally.
