LK Wood 22 Underfloor Heating Install Demo

LK Wood 22 Underfloor Heating Install Demo
This video shows a demonstration of laying the LK “Wood 22” system. LK Systems Wood 22 is an underfloor heating system which is laid over joists with insulation beneath. It is a load bearing floor made of 22mm chipboard, routed to accomodate the underfloor heating pipe. Wood 22 brings the underfloor pipe closer to the final covering than a conventional joist plate or foil system. This equates to a lower energy bill and/or a greater heat output per m² than other joisted underfloor heating systems.

Air Conditioning – NRG Heating and Air Conditioning

Air Conditioning – NRG Heating and Air Conditioning
HVAC is an acronym for Heating Ventilation and Air Conditioning. Basic residential HVAC systems consist of 3 varying types:

The first kind, which is also the most common, is called the Split System:
-This HVAC system consists of an Air Conditioning Condenser (the unit sits outside, usually on the side or back of the home or on the roof), the Evaporator Coil, the Furnace, and the Air Duct System.
-The condenser compresses the refrigerant, transforming from a gas to a liquid state, and is then transferred to the Evaporator Coil.
-The air then passes over the Evaporator Coil, where it is cooled. The Furnace uses natural gas via burners located in the furnace to heat the home
-The Evaporator Coil is always situated with the Furnace, whether horizontally in the attic or installed as an upflow/downflow, which would be situated in a closet or the garage.
-As the air is sucked in by the Furnace through a return air grill, it then blows over the Evaporator Coil, which cools it, and then into the ducts, which blows the air into the home.
-The air travels throughout the home via a flexible polyurethane Air Duct System.

Another type of HVAC system is the Packaged Unit:
-This HVAC system is usually situated on top of the roof and contains both the heating and cooling components in one piece of equipment (hence the “packaged” name).
-it uses both natural gas and electricity
-The air is brought in the system, heated or cooled depending upon the desired setting, and pushed down into the air duct system.

The 3rd type of HVAC system is called the Heat Pump System
-This HVAC system runs solely on electricity and heat and cools via the refrigerant in the system.
-The system consists of a Heat Pump Condenser (which usually sits on the side or back of the home or on the roof) and an Air Handler.
-The Heat Pump Condenser uses refrigerant to heat and cool the air (through reversing valves), which is then sent into the Air Handler.
-The Air Handler pushes the air into the Air Duct System with blower motor.

Why Underfloor Heating
The majority of the population now spends at least 22 of every 24 hours in some kind of artificial climate. Underfloor heating is far from a new concept, it was first used by the Romans whose dwellings were constructed with voids through which air, warmed by an open fire, would pass, thus heating the structure.
Underfloor heating is not a new concept in this country either. In the past electric heating elements were buried within floor screeds. These were heated over night using ‘cheap rate’ electricity. However, this method was expensive to run and uncontrollable and the building would over heat during the day but in the evening, when heat is generally required, no further heat was available.
Utilising today’s modern multilayer pipes, control systems and high efficiency boilers, the underfloor heating systems of today are extremely comfortable and controllable. Radiators are no longer needed so giving more room space. The heat is more evenly distributed and dust is not circulated.
Underfloor heating from the whole floor area of the house gently warms the air above, eliminating cold spots. The warm air convects from the floor surface losing approximately 2 degrees centigrade at 2.0 meters above the floor, which makes the system ideal for all ceiling heights. Independent tests reveal that the most acceptable indoor climate is one in which the floor temperature ranges between 19-29°C and the air temperature at head level ranges between 20 and 24°C. With radiator or convector heating systems a vertical temperature gradient is produced; colder at foot level than at the head.
Underfloor heating has made it possible to reduce energy consumption by using low water temperatures. These systems, based on the development of complex and very high quality plastic pipe, such as the multilayer pipe, now account for over 60% of some European heating markets.
