Today, I will expose the secrets of the floor heating industry, so that those customers and friends who are ready to install floor heating or want to install floor heating can have a look.
This article may offend many colleagues. I suggest you collect it and read it patiently.
First, especially our customers and friends in Nanjing, when you install floor heating, you must remember to pay attention to one of the most critical issues, that is, the insulation of floor heating houses, because we are completely different in the south and the north. The inner and outer walls of the south house are not insulated, while the inner and outer walls of the north house are insulated, so the main reason for your high energy consumption every month is directly related to the insulation.
Second, the power of the wall-hung boiler can be chosen to be small rather than large. If you ask me why, there is too much content, you can tell me in private.
Thirdly, the coil spacing of our floor heating should be as close as possible, which is like pouring the same water into different plates or cups, and its heat dissipation effect is different.
Fourth, it is traffic. I don't care whether you buy a 18kW wall-hung boiler or a 36kW wall-hung boiler, then the standard water pump in the boiler is 6m. If you want to rely on the water pump of this boiler to radiate heat evenly in every room, it is absolutely impossible. Therefore, for larger units, this secondary system must be added. There is also a water separator that we use. We can choose stainless steel instead of brass. Brass is not copper. Brass has holes.
Fifth, it is the reflective film commonly used in floor heating. Reflective film is just a screen cloth, its main function is to distinguish the distance between pipes during construction, and the others have no effect.
Sixth, many of our customers are struggling with the choice of floor heating pipes. Now many merchants blindly recommend pexc pipes and aluminum-plastic composite pipes, forcing brainless differentiation. In fact, qualified oxygen-resistant PERT floor heating pipes are enough to meet all the requirements of our floor heating water supply.
Seventh, it is the electric actuator of the water separator, which is the most prone to problems and has no other requirements. You just need to ask your HVAC engineer to write you a warranty in the contract and replace it for free within five years.
Eighth, don't choose the floor heating system of wall-hung boiler brand. I've seen too many people step on the pit. You bought a floor heating system instead of a wall-hung boiler system.
