What pipe should I use to keep warm?

At present, the pipe connection of radiator adopts aluminum-plastic composite pipe or PPR steady pipe. At present, there are two kinds of common metal pipes, which are stable, firm and durable. Iron pipes also have heat dissipation function to increase the heat dissipation area. If the plastic pipe is worn, the floor heating coil is used more, which is oxidation-resistant, corrosion-resistant, rust-proof and paint-free. Easy to install and maintain when exposed.
