Radiant floor heating problems and solutions

If used correctly, the floor radiant heating in running costs than convection heating system can usually be reduced 20%, 40%.
In the room floor, the room, the wall heat preservation condition, toward the window size and whether to adopt double hollow glass, have the house from a heat preservation, cooling condition, such as monomer villa more directly with the wall outside contact cooling more, if the heat preservation is bad, the room to reach the same temperature, heating quantity required may increase exponentially. Secondly, the use of every family habits and different families need comfortable temperature varies 2 ~ 5 ℃, also some family habit morning and evening two half hour window natural ventilation, all of the operation cost the influence. Floor heating way USES radiation heating, heating accord with human body physiological demand curve, indoor set temperature even than streaming heating low 2 ~ 5 ℃, also can make people have the same warm feeling, and floor heating low-temperature heat source temperature difference heat loss greatly decreased, and the heat convection heating is greatly improved, and this can make the system operation cost reduce 20 to 30%. If selected, use the control system is proper, can not only improve the room comfort, more can make the system operation cost reduced from 40% to and many more.
Usually, people think that "radiant floor heating" is specially designed for the independent heating, actually central heating the user may in their laid pipe, become air convection for the floor radiation, but adapted to pay attention to control temperature.
Heating or central air conditioning of central heating area hot water supply temperature of 60-90 ℃, if direct connection floor heating system obviously temperature is too high, it will not only for high temperature surface caused by human body unwell, also reduced the life of floor heating system. If the door in the central heating set up mixed flow bypass connections floor heating system, and will floor heating water temperature control of the system in the ground for 30 to 50 ℃ temperature, can use floor heating system.
Now all qualified decoration market, real wood floor, solid mu fu joins a floor board, aggrandizement wood floor, stone, ceramic tile, linen, wool carpet carpet, ShuiNiZhuan, rubber floor and the adornment material such as DeBanGe can be used for floor heating. But the ground heating floor use environment is much more complex, the processing technology requirements are higher. Generally, the installation of geothermal system room should try to choose aggrandizement wood floor, because the thickness of aggrandizement wood floor is mostly in about 8 mm, it's very easy to geothermal system to produce a quantity of heat conduction to the surface, and the surface of the aggrandizement wood floor for metal oxide wear-resisting layer of, quantity of heat in the earth's surface and evenly spread quickly. Real wood floor thicker, installation also play keel, so not easily to the surface heat conduction; In addition, the heat transfer coefficient of the wood is very low, easy to crack, also can cause the waste heat surface temperature and uneven--Composite Wood Outdoor Flooring.
Smooth layer family general in typical position (sitting room, advocate lie) installed a temperature control device, temperature control devices connected to wall-hang boiler, the thermostat according to room temperature and the temperature setting directly regulate boiler water supply temperature, operation of each room temperature rise with with drop. You can please professionals with experience manual adjustment for water ball valves, to a different circuit valve opening Settings, change different circuit flow, which regulates the relatively high and low at different room--Wood Plastic product.
Jump layer family more using zoning control, common in each floor alone setting for water, put a thermostat will area temperature feedback to the water inlet water valve, regulate water flow, and then adjust the temperature in the floor, the same floor with liters each room temperature with drop.
As for single-family villa owners, might be in comfort the demand is higher, and greater difference between use function room (advocate bedroom, children room, toilet, garage, guest room, gymnasium, function hall, etc), that requires points room control, that is, the same water of the device on the different circuit to adjust temperature respectively--wood plastic composite.
