Expansion tank - The tank at the top of on open system, allowing you the expanding hot water in the cylinder to spill out and become stored.
Expansion vessel - A little tank used in finished water heating systems and domestic warm water systems to absorb excess water pressure, which can be caused by thermal improvement as water is heated. The vessel itself is a small container divided in two by a rubber diaphragm. One side is linked to the pipe work with the heating system and consequently contains water. The many other, the dry side, contains air under pressure. This is not much like an expansion tank.
Because of this, TRVs are the environmentally friendly valve choice as these people prevent energy wastage.
Towel radiator - A radiator that is designed specifically to warm towels and a room, often used with bathrooms or kitchens.
Small towel rail - Historically that phrase just meant a rail for hanging bath towels, but over recent a long time this phrase has come to mean a radiator that's designed to keep towels warm and dry. It can be now used in both instances. Other terms used included heated towel rail and towel radiator.
TRV : See "Thermostatic Radiator Valve"
Un-pressurized system- see "Open System"
Valve - A tool that regulates, directs or controls the flow of a fluid by opening, closing, or partially obstructing various passageways. In radiators and central heating systems, valves are utilized to control water flowing around a pc and particularly in and using radiators.
Wall tie - a tool used to attach a radiator or akin to a wall. Sometimes called a wall stay.
Watts : A derived unit of power in the International System of Versions (SI), named following your Scottish engineer James Watt (1736-1819). The device, defined as one joule per second, measures the rate of energy conversion. In heating, watts are used to measure the heat output given by a heat source for example a radiator.
75-65-20C operating temperature- Water for a hot water piped process will leave the boiler at 75C and return to the boiler at 65C losing a nominal 20C across the whole system. See also Dt 50C
90-70-20C operating temperature- Water on a hot water piped system will leave the furnace at 90C and return to the boiler at 70C losing a nominal 20C across the whole system. See also Dt 60C
If you ever can't find the information you would like above or need help with choosing a radiator, then contact a specialist.

http://community.atom.com/...AB500080182A7B3 The ski chalet industry is now through rapid change as consequence of the influx in private chalet operators since turn of the Millennium. Reports such as Morzine, Val d'Isere and Verbier in particular have seen their ski resorts turn into a tiny outpost of current colonial Britain. However the ski resort containing probably seen most change in respect of the British inflow is Chamonix. An all year resort and well-known for Mont Blanc, Western Europe's highest mountain at 4, 810m, Chamonix's affinity with your British goes back centuries due to its climbing heritage and in later years skiing. In fact Britain's romance with the Alps together with Chamonix dates back as much as the 18th Century, a long time before alpine skiing was devised.
