Supply ventilation combined with channel air conditioning (part 2 - water)

I want to share my experience in the design, installation and operation of my fresh air system combined with duct air conditioning. The system
was assembled in 2012-2013 and has since been in constant operation.

The article is divided into two parts:

• in the first part , a classic ventilation scheme using an electric duct heater was described
• in this part I’ll tell you about the mixed experience of processing a system for a water heater with power from a common heating system

Thanks to the masters

Once again, many thanks for the constructive and critical advice of specialists, without which I could not create and configure the system.

• the user Kim for the extremely valuable advice and attention to my questions
• Fresh user for ongoing support
• user mr-h for the valuable advice and active participation

I began to pay for heating 2 times more. The kopeck piece on our site consumes more than my apartment including batteries and an aerial. They probably began to pay less.

So I will restore the system.
