How Central Vacuum Systems Work
A central vacuum cleaner is a type of vacuum cleaner appliance, installed into a building as a semi-permanent fixture. Central vacuum systems are designed to remove dirt and debris from homes and buildings, sending dirt particles through tubing installed inside the walls to a collection container in a remote utility space. The power unit is a permanent fixture, typically installed in a basement, garage, or storage room, along with the collection container. Inlets are installed in walls throughout the building that attach to power hoses and other central vacuum accessories to remove dust, particles, and small debris from interior rooms. Most power hoses typically have a power switch located on the handle.
Cleaning the house may not be your idea of a fun activity. But while vacuuming may never be fun, there is a way to make the job a little easier.
Most of us vacuum with the standard moveable unit, but have you ever thought of installing a central vacuum system in your home? Central vacuum systems are becoming more common.
Health benefits: With central vacuum systems that exhaust completely out of the home, no dust or allergens can be re-circulated through the interior air, as is the case with traditional vacuums.
Operation: To use a central vacuum, the vacuum hose is taken from storage and fitted with any needed cleaning accessories (such as a brush). The other end of the hose is inserted into a wall-mounted vacuum inlet, after opening the spring-loaded cover door. In some designs, opening the door switches on the vacuum motor; in other designs, insertion of the metallic hose-end fitting bridges two electrical contacts, signaling the motor to turn on. Other alternative designs feature a remote on/off switch located at the tool end of the vacuum hose, which communicates either via a pair of wires embedded in the hose, or via wireless signaling.
Drinking Water
Drinking water or potable water is water safe enough to be consumed by humans or used with low risk of immediate or long term harm.
Some health authorities have suggested that people drink at least eight glasses, each (240 ml), of water per day (64 fl oz, or 1.89 liters),and the British Dietetic Association recommends 1.8 liters.
Tap water or public water is treated at municipal water treatment plant and it is safe to drink but it is not pure as it contains traces of salts such as magnesium, calcium, carbonates, bicarbonates and others.
How heating and cooling systems work?
Most of us take heating and cooling for granted. We expect our heating systems to keep us warm during the winter, and we depend on air-conditioning to keep us cool during the summer.
When the house is cold in winter or hot in summer, the natural reaction is to call for professional service. Fortunately, there is an alternative. You can cut service costs drastically and keep your heating and cooling systems working efficiently by doing some maintenance and quick fixes yourself. But first, it's important to know how the basics of how heating and cooling systems function.
All climate-control devices or systems have three basic components: a source of warmed or cooled air, a means of distributing the air to the rooms being heated or cooled, and a control used to regulate the system (e.g., thermostat). The sources of warm air, such as a furnace, and cool air, such as an air conditioner, in a house often use the same distribution and control systems. If your house has central air conditioning, cool air probably flows through the same ducts that heat does and is regulated by the same thermostat. When a heating or cooling system malfunctions, any of these three basic components may be causing the problem.
