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.
Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated PVC, is the third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene.PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible.The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used for bottles, other non-food packaging, and cards (such as bank or membership cards).PVC, also known as rigid PVC, is extensively used in the building industry as a low-maintenance material, particularly in Ireland, the United Kingdom, in the United States and Canada. In the USA and Canada it is known as vinyl, or vinyl siding.
