Full analogues do not exist, which is confirmed by the fact that the design of “Termanik” is patented. There are some boilers of this type on the market, but with a different design of the secondary winding, i.e. heat exchanger. Other frameworks of heat exchangers that are used by other manufacturers may be less resistant to scale formation, local overheating and unequal magnetic field distribution. Such designs are less reliable, more difficult to repair, more material-intensive, and therefore more expensive for the buyer.
