Expect to pay as much as $5,000 to $7,500 for a ground-source heat pump system. Air-source heat pumps can be found for much cheaper, averaging around $1,500 to $4,000, because the units tend to be simpler, and installation is easier. The cost required to run and repair a heat pump varies with the type of system.
PVC decking. PVC decking is composed entirely of Polyvinyl chloride (PVC) and contains no wood. PVC decking is a more expensive option in the decking industry, but it provides significant fade and stain resistance and lower maintenance requirements compared to other products. Contents.
PVC (polyvinylchloride) is generally seen as a har â¦ d plastic. It is made from vinyl chloride monomers which are pieced together to form a long chain. These are then placed alongside each other to form a coherent strand. This strand can be made into almost any shape with the use of heat and pressure.lastic resins are, in turn, used to produce many different types of plastic. The majority of what we know as plastic today is made from materials that are extracted from crude oil. Often the same type of crude oil that is used to produce the fuels for cars.
