Greenhouse & Floriculture: Root Zone Heat - Installation

Hot water from an existing or new boiler can also be used. One or more circulators and tempering valves are needed to feed the root zone heat. Because the return water from the root zone is cool, a non-condensing boiler should not be used. Cool water, less than 135ºF can cause condensation that is highly acidic and can damage the boiler.
