(57) By the new technical solution is achieved maximal using of transmission of heat to
water what is enabled flowing of water around the heater (1) which is in the tube
(2). By the particular solution of the indicator of flowing (3) is enable using of
boiler for any nominal pressure in city's water supply. Indicator of flowing (3) is
solved in such way, that is damage of boiler is impossible / explosion of too big
pressure , switching on without water, etc. /. Heater switchs on itself in section
over the reed switch (5), resistor of breakthrough of voltage. The complitly technical
solution enable saving of electricity around 80% and is very easy for assembly-line
production.

The field of technology
[0001] The field of invention is heating of water or any other medium, by means of electric
power for heating of medium in flowing.
Technical problem
[0002] Technical problem is solved by the heating of medium in flowing and maximal using
of transmission of heat to medium which heats itself / water, oil, etc./ like a same
system of switching on the boiler.
The state of technology
[0003] Previous technical solutions which are known to me, haven't maximal using of transmission
of heat and former boilers weren't multi-purpose that mean they weren't adopt of work
on any nominal pressure in tubes / city water supply, etc./
Description of technical problem
[0004] In contrast to existing boilers of passage at this boiler of passage, heating is
achieved in tube through which flowing the water / or smth. similer/ and there is
in the middle of the tube, throught the entire length, the electrical heater which
heats water in flowing.The way of switching on the boiler calls out moving of driving
magnet in indicator of flowing of water, in any flow and in any pressure and than
pull toward by the magnetic forces the contacts of reed switchs.
[0005] On that way close the power circuit through " the zero guide " and resistor, and
give the inducing power to triac / gate / and switch on full power of heater under
voltage.
[0006] By this way, can be achieved exceptional incontenstablement and safety of working,
especially at low flowings and pressures of flowing of water, can not produce pressure
of overheating and switching on boilers is impossible without pressure in water-supply.This
technical solution can be used for any nominal pressures.
The boiler of passage is technicly solved for maximal using of transmission of thermal
energy to water indicated that heater 1 is put in tube 2 which is mechanical combined
with indicator of flowing 3 which because of that switch on through the driving magnet
4 and reed switch 5 triac 6 and by the resistors 7 and 8 pass through the maximal
energy on heater 1.
