Scary Secret In An Old Fireplace

A fireplace is an architectural structure that is made to contain a fire. Fireplaces are used at the present time mostly for the relaxing ambiance they create. Historically they were used for the practical purposes of heating, cooking, and heating water for laundry and domestic uses.

A fire is contained in a firebox or fire pit; a chimney or other flues are built to allow exhaust to escape. A fireplace may have: a foundation; a hearth; a firebox; a mantelpiece; a chimney crane, used in kitchen and laundry fireplaces; a grate; a lintel; a lintel bar; over mantel; a damper; a smoke chamber; a throat; a flue.

On the exterior there is often a corbeled brick crown; the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.

Fireplaces have variable heat efficiency. Organizations like the Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a significant health risk.

Biggest Air Conditioning Fail Ever

Air conditioning is the process of altering the properties of air (usually temperature and humidity) to more favourable conditions. More generally, air conditioning can refer to any form of technological cooling, heating, ventilation, or disinfection that modifies the condition of air.

An air conditioner (often referred to as air con, AC or A/C, and not to be confused with the abbreviation for alternating current) is a major or home appliance, system, or mechanism designed to change the air temperature and humidity within an area (used for cooling and sometimes heating depending on the air properties at a given time). The cooling is typically done using a simple refrigeration cycle, but sometimes evaporation is used, commonly for comfort cooling in buildings and motor vehicles. In construction, a complete system of heating, ventilation and air conditioning is referred to as “HVAC”.


Air conditioning can also be provided by a simple process called free cooling which uses pumps to circulate a coolant (typically water or a glycol mix) from a cold source, which in turn acts as a heat sink for the energy that is removed from the cooled space. Free cooling systems can have very high efficiencies, and are sometimes combined with seasonal thermal energy storage (STES) so the cold of winter can be used for summer air conditioning. Common storage mediums are deep aquifers or a natural underground rock mass accessed via a cluster of small-diameter, heat exchanger equipped boreholes.

A Nasty Surprise Inside A Wardrobe

A wardrobe, also known as an armoire from the French, is a standing closet used for storing clothes. The earliest wardrobe was a chest, and it was not until some degree of luxury was attained in regal palaces and the castles of powerful nobles that separate accommodation was provided for the apparel of the great.

The name of wardrobe was then given to a room in which the wall-space was filled with cupboards and lockers, the drawer being a comparatively modern invention. From these cupboards and lockers the modern wardrobe, with its hanging spaces, sliding shelves and drawers, evolved slowly.

Etymological origins of the name can be traced to the Middle English rendering of the ancient French term, garderobe with the semantic import of a private store. Its more precise language origin is armoire for Francophone speakers. The 17th and 18th centuries marked the baroque period’s versatile exploitation of the wardrobe which helped it transmute to the modern type. In the Americas, oaken structures referred to as the tallboys were much in appeal though they later changed to the walnut types after the passage of oak as the hitherto preferred timber and partly due to the partial extinction in virgin forests of the latter wood. At first, the progress from the normal cabinet to the now fully-fledged structure was marked with bulky shelves and drawer-straddled wardrobes for a century or so before the now minimalist walled-in style became the functional norm.
