A pensioner invented and patented a device for economical heating of a summer cottage

Hello everyone! I want to tell you about a talented resident of the Tambov province, who invented with his own hands and mind economical heater, which today successfully and inexpensively heats his country house under Tambov.

Author of the patent - Alexey Igorevich Zuev, retired engineer with his first education and a builder with his second education. Patent number: 182950. If you are interested, look in Yandex. Patents.

The device that Zuev invented is suitable both as an independent and as a backup heating system for a country house or summer cottage.

The source of energy for the heater is very simple: it operates from an electrical network with a capacity of up to 230 volts (it also works at a reduced voltage in the suburban electrical network to 130-140 volts).

Constructive

Heater Zuev - a hermetically sealed flask made of thick glass, inside of which a heating element made of nichrome, an alloy of nickel and zinc or a carbon thread is installed through the end sleeves.

In addition to the heating element, a coolant is pumped into the flask for its entire volume - an ordinary purchased coolant from a hardware store.

In this case, the main feature is that the coolant was pumped into the flask in an already hot state and only then the flask was sealed from both ends.

The efficiency of such a heater is 99.5%, which means that almost all 100% of the electricity spent on heating is converted into heat energy.

The main plus, according to the inventor, is that with such a system you do not need an expensive electric boiler.

Thanks to the built-in thermostat, the device is not afraid of overheating and reduces power (and electricity consumption) in the event of a threat of overheating.

Device cost: 1000 rubles
