The deceptively cute Gray Jay is one of the most intrepid birds in North America, living in northern forests year-round and rearing chicks in the dark of winter. Highly curious and always on the lookout for food, Gray Jays eat just about anything, from berries to small animals. They may even land on your hand to grab a raisin or peanut.
A thermal insulator is something that prevents heat from moving from one place to another. There are 3 main ways that heat can travel: convection, conduction, and radiation. Typically the phrase 'thermal insulator' refers to a material that blocks conduction.
An accumulator is a tank designed to store a volume of hot water, and the vessel should be very well insulated to reduce heat loss. The size of the accumulator or buffer tank depends on the system performance required, and the size of the heating load.he benefits gained from using an accumulator are substantial. Because the heat is stored, the wood boiler can be fired and stoked at a convenient time, and the heating and hot water timed independently with a timer / programmer when required.
