The heating expert came to see it. Is that a return pipe? Please help.

How to distinguish the water inlet and outlet pipes: Generally, the water inlet and outlet pipes of radiators are left in and right out.

Heat up the bedroom radiator, which means it wasn't hot before? Or do you want him to be warmer ?

● The reflective film is installed behind the radiator.

By reflecting hot air, the indoor temperature can be increased. Specifically, aluminum gusset plates with metal surfaces, metal films of kitchen stoves or metal films for baking food can be installed on the wall between the radiator and the wall to play the role of heat preservation and heat reflection of the radiator.

● Install sealing strips on doors and windows.

Some old houses are still using aluminum alloy doors and windows or steel windows without sealing strips, and some doors and windows are new. However, after using sealing strips for a period of time, there will be the problem of aging sealing strips, which will lead to indoor heat loss. This requires installing sealing strips and replacing sealing strips. Especially for the entrance door of the room, if the sealing strip of the security door is aging and falling off, the heat loss is serious.

● Glass thermal insulation film and thermal insulation coating.

In winter, 40% of indoor heat is lost through window glass, especially in some rooms with floor-to-ceiling windows, and the indoor temperature is bound to be lower in winter. In this case, the methods of sticking glass insulating film and brushing glass insulating paint can be adopted. Tested by the Indoor Environmental Monitoring Committee, the indoor temperature can be increased and heat loss can be prevented without affecting the light transmission function of glass.

● Change the interior decoration style.

In addition, for the visual warmth effect, fabric furniture can be used instead of solid wood or iron rattan furniture in winter, and wooden seats can also be wrapped with fabric materials. The living room and bedroom should be carpeted with stones and tiles. Lighting equipment should also be replaced by warm light sources, tapestries should be hung on the walls, and curtains with heavy texture and dark colors should be replaced.
