Why heaters are not equipped with a thermostat, if regulators are so necessary?
Thermostat and heater are
two different devices independent from each other. For example, for the same reason bulbs are not supplied with switches because there can be few light bulbs in the
room, but you only need one
switch. Number of thermostats is selected according to the
temperature zones, so you can buy
them from us as many as you want.
