(3) price: due to the purchase of raw materials and processing technology, the market price of similar-looking products but there are high and low, consumers can not be considered when buying low price. Some manufacturers for the pursuit of profit, the use of inferior parts in the production and manufacturing to reduce costs will bring safety hazards to consumers.
(4) type: consumers can choose according to their own use of the environment and conditions: electric heating oil heating surface temperature is low, comfort and thermal security is good, suitable for people, places with children, but its thermal inertia, slow warming, the volume is also slightly larger. Heater small size, easy to move, warming up fast, but energy consumption is relatively high, easy to have a dry feeling.
(5) after-sales service: in general, the well-known brands of after-sales service will maintain about 3 years, while substandard products are often difficult to do door-to-door maintenance and even manufacturers. In addition, consumers in the use of electric heating must be in accordance with the instructions for operation, instructions such as "shall not be placed under the socket to use" "prohibit the coverage" and other warning terms, especially to pay attention to.
3, water underfloor heating purchase points:
(1) look at the main material: low-temperature hot water underfloor heating the first look at the pipe, PERT pipe and PB pipe is the world's first floor heating piping system, pipe of course, we must choose the name brand, the production of PERT pipe and PB pipe manufacturers at least more than 10 years of production history.
(2) look at the insulation material: water floor heating system under the insulation material can not only maximize the reduction of heat loss downward, but also can avoid long-term use of insulation materials under the aging phenomenon, the ground material should be the first choice of more than 2 cm extruded plastic insulation board, if you choose to use polystyrene foam board, the density should not be less than 30kg / m3. In addition, the insulation board should be a fuel-blocking, which is very important. very important.
(3) look at the intelligent thermostat or other auxiliary devices: the use of intelligent thermostat can improve the comfort of underfloor heating, and effectively reduce energy consumption. It is also worth recommending the secondary water mixing device, as the floor heating system development trend, the secondary water mixing device can avoid frequent startup of the boiler, directly reduce energy consumption, or to protect the pipeline from excessive high water temperature.
(4) installation design: water floor heating as a HVAC professional a new technology, invention and use of only a few decades, the introduction of the country is only a few decades, the design is more complicated than the traditional radiator system, design research and experience in the province is not yet mature, the design of water floor heating system should be designed after a rigorous and careful calculation and detailed research.

The procurement of heating system should not only emphasize on good products, but also on good technical support and lasting and stable after-sales service behind the products.
4, electric floor heating purchase points:
(1) the main material selection: electric floor heating as a new type of floor heating, and can be divided into several kinds, such as heating cable floor heating, electric film floor heating, carbon crystal floor heating and so on. And according to underfloor heating experts, among all electric underfloor heating, heating cable electric underfloor heating is currently the safest, the most reliable, the most popular and the most convenient to use.
(2) choice of auxiliary materials: electric floor heating, although auxiliary materials relative to the water floor heating is less, but the insulation board, reflective film and steel wire mesh, these should be strictly in accordance with the data provided by the designer to purchase, so as to avoid the quality of auxiliary materials caused by the failure of the entire heating system, it is not worth the loss.
(3) thermostat selection: heating cable electric floor heating, in addition to the heating cable, another big thing is the thermostat. Among them, the thermostat is the operating end of the user's control of the electric floor heating system, so it is also very critical. Daewoo floor heating experts say that the quality of the thermostat depends on its own quality and the quality of the control program. Dual temperature dual control type intelligent thermostat for underfloor heating can control the system temperature in six periods a day, which is more convenient to use.
(4) floor heating system installation: floor heating system in the industry has always been "three points of the product, seven points of the installation", so the installation of electric floor heating is very important. As a whole set of heating system, not than to buy a simple electrical appliances, so be sure to choose a professional builder, otherwise it is easy because of improper operation, resulting in damage to the heating cable line, which in turn makes the electric floor heating system can not run normally.
5, wall-hung boilers to buy key points:
(1) choose the right power products: should be based on the size of the house area, structure and whether the need for hot water and gas to choose the right wall-hung boilers. First of all, first of all, through the house area to roughly calculate the choice of which power of the wall-hung boiler, here is a recommended formula for calculating the approximate power: the house floor area × 65% × 150w.
(2) choose high-quality accessories: through the wall-hung boiler within the configuration of the parts and components to determine the purchase. Such as European imported parts of better quality, its price is higher, generally in the 5000-10000 yuan, such products in all aspects of performance, safety and energy saving more advantageous.
(3) choose to have the advantage of service products: buy wall-hung boilers to look at the brand, the brand is good quality is guaranteed, and more importantly, can guarantee the safety of after-sales service. The general service life of the wall-hung boiler in more than 15 years, in addition to the two-year warranty there is a minimum of 13 years of charges maintenance guarantee, if there is no good service escort, problems can only spend expensive replacement of new products.
(4) the best choice with anti-freeze function products: purchase wall-hung boiler must have perfect anti-freeze function, in order to prevent accidents in winter. Automatic anti-freeze function of one, when the water temperature drops to 5 ℃, the boiler must be able to automatically start. The second, when the gas is cut off, at 5 ℃, the pump should run continuously.
(5) focus on product energy efficiency: as the whole winter to use the wall-hung boiler, which requires special attention to the energy efficiency of the wall-hung boiler, choose a good energy-saving wall-hung boiler, not only can reduce the cost of consumption, but also to improve the quality of life.
6, carbon crystal wall heater to buy points:
(1) stability should be good: it is understood that look at the wall heater substrate, density and internal bonding strength, the higher the internal bonding strength, indicating that the carbon crystal wall heater to withstand temperature changes in the ability to the better, not to the occurrence of cracking and other phenomena, only the substrate for the relatively dense carbon crystal wall heater to ensure that the long term at high temperatures do not crack, do not deform.
(2) formaldehyde emissions can not exceed the standard: this requirement in the conditions of prolonged heating, formaldehyde emissions will not exceed the standard. Consumers choose carbon crystal wall heater, must choose as low as possible formaldehyde content, because the higher the temperature, the more formaldehyde release, in a relatively closed apartment, plus formaldehyde release caused by other items indoors, indoor formaldehyde may exceed the standard, harmful to the human body.
(3) heat transfer should be fast: in the market, the current can provide thermal conductivity coefficient of the brand is not much, consumers should pay attention when buying. General coefficient of high products in heat conduction better performance. Not afraid of high temperature, because the carbon crystal wall heater has to withstand high temperature heating for a long time, the requirements of the product decorative layer performance is stable, in the long time high temperature conditions will not appear fading, brown light phenomenon.
(4) Choose a well-known brand: carbon crystal wall heater is best to choose a well-known brand, so that if there is a problem in the process of use can be good and timely solution. And there is also a great guarantee of quality, not to use a period of time on the problem.
