Specifications & Restrictions
Circulators
Material Properties
of Components
The parts used on the RHP are composed of non-ferous material. The types of materials used that
are in contact with water are brass, TP 304/TP 304L stainless steel, and EPDM rubber.
The NIBCO
®
RHP is pre-assembled and pre-wired using our standard products. The circulator has
been selected to handle the flow requirements for a typical system plus a marginal allowance for any
additional pressure capacity not considered. The circulator will be undersized if there are more than
the maximum loops, if the loops are longer than 250 ft. or if they are smaller than 1/2” in diameter.
Manifold Connections
Boiler vs. Domestic
Water Heaters
The RHP-1 is designed for 3/4” PEX piping to and from the heat source and to and from the distri-
bution manifold. The RHP-2 is designed for 1” PEX piping.
Any heat source such as a domestic water heater, cast iron boiler, outside wood
furnace or other heat source is compatible with this RHP.
NOTE: The circulators supplied with the RHP are suitable for potable ap-
plications. If any type of glycol is used in the system, it must be isolated
from domestic water use. Propylene glycol is posionous and ethylene
glycol is toxic. Follow codes and standards of authorities having jurisdic-
tion.
With Glycol, use a stabilized glycol, a separate stabilizer, or change
fluids annually to avoid a buildup of corrosive glycolic acid.
Pressure losses have been dimensioned based on design flows through ½” nominal PEX tubing at
a rate of 0.5 to 0.7 USgpm. A nominal 9 ft. of head for the radiant tubing and 4 ft. of head for
control valves, pipe and fittings has been allowed for in the circulator selection.
If system requires a larger circulator, you should consider a modular approach and use multiple
RHP’s. Mixing valves have been selected to provide sufficient flow for a minimum and maximum
case.
The RHP utilizes an electronic thermostat, which is placed within the room where temperature is
monitored by an internal room sensor.
