          Heating radiator ( radiator) purchase consideration should be given to attention problems and points are mainly the following ten points:

          In 1, choice of consumer satisfaction or after sale service trustworthy home furnishing market.

          In 2, around three, in the same style, the same brand of goods, from the quality, price, service and other aspects of comprehensive consideration.

          3, security of the security performance of radiator is the most important. Relating to the safety performance of many factors, including the radiator pressure is a very important, many domestic and foreign radiator with bar as unit, most of the work pressure is above 10bar,1bar can withstand the equivalent of 10m10bar100m water column pressure, water pressure, for the broad masses of users10bar or above the radiator should be is a reasonable choice.

          4selection selection should be clear, own import and export requirements at room temperature, room temperature, heat load, sill high and wide, their use is single or double pipe heating system and other factors, there is a selection formula: Q = K t S (t inlet temperature outlet water temperature and room temperature + Q; indoor heat load, K, radiator and air conduction coefficient; S - living area ). That is to say the radiator to heat load and rooms, to meet our own heating requirements, thus to obtain the heat load value corresponding to businesses that find out corresponding table selection type radiator.

          In 5, the firm has many years of production of heating equipment experience, whether the products meet the national standards.

          6, whether can provide good after sale service, there is no professional plumbing measuring installation team.

          In 7, is the choice of type or column type radiator. The small size of the space, such as a toilet, can choose the column type radiator, because it adopts hanging type, can save indoor space; the transverse column can be hung on the towel or baking the small clothes; for larger room, suggested buying plate radiator, the increase in convection board, radiation and convection heat sinks can be to make room in the shortest time to achieve the best cooling effect, and can save a lot of energy.

          8, heat flux and the import and export of pipe sizes no actual relationship, mainly to see water in the heating of the velocity, as long as the velocity of water can reach the standard, heat dissipating capacity will also be guaranteed. Think heating pipe import and export of large size, heat dissipation is good view is wrong.

          9, invoice, contract must specify the name of the radiator, specifications, quantity, price, amount.

          In 10, the host unit and the manufacturer's name, address, contact person, telephone, so that any quality problems can contact address.
