What equipment does Heilongjiang use to keep broilers warm? We all use hot stoves here. I hear the water heater is good. I wonder if Heilongjiang can be used. ...

Water heaters are ok, but the equipment cost of water heaters is much higher. Whether installing radiators or water heating and air conditioning, it is much more expensive than installing hot air belts in hot stoves. There must be Heilongjiang. At present, there are many energy-saving and environment-friendly automatic temperature control hot stoves, which are also very good. You can choose from many aspects.
