hydro air heating and AC

Does anyone have any specs on hydro air heating and AC systems?

I have this system in my house for 6 yrs. Just inspect the boiler as a normal boiler and the AC air handler as such. Just explain how the boiler sends hot water not to baseboards or rads but rather to a coil within the air handler that blows air over these hot coils and out through the supply registers to their rooms. Its a great system although not seen often.

Nowadays, Hydro Air System becomes more and more popular. A hydro air system is a combination of a hot water and a hot air system. The main advantages of hot air systems are

  1. Ease of zoning
  2. The proper sizing of zones
  3. Increased comfort levels.
  4. The ability to easily expand the system and generate the heat.
