Which model HB should I buy?
For best efficiency and to suit your preferred use, you may select between different HB modules for:
- HB65A for 6-9 litres per minute flow rate for Unequal, Medium and High Pressure Systems; (Available now) pressure drop of this model is 50 kPa. (102 kPa at 9L/min.) Note code regulations allow up to 10L/min. for this unit. By piping the pre-warmed water to the mixer you can reduce the velocity.
- HB65B for 6-13 L/min. flow rate for Low to High Pressure Systems. (pressure drop of this model is, with 20 kPa, is the lowest available). Note noise regulations allow up to 20L/min. for this unit.
- HB65C for 5-6 Litres per minute flow rate. Use with water scarcity; (Please state pressure of your supply system). You may need to check if this is practical before ordering as these are made to order only).
Refer also to Product Overview or 'Order' page for model selection assistance.
Please note: Models HB65A to C are sized for discharge pipes up to 65mm and a flow rate demand to 13 ltr/min. Flow rates above 13L/min. may use any two modules in parallel configuration or one unit may be configured for uneven flows to serve up to six hot water fixtures.
Heat resistance; The above rigid PVC /Nitrile/Cu design are formulated and tested to process domestic wastewater up to 72ºC. (AS/NZSS 1260) The same standard as applicable to town sewer systems. Run off from industrial type dishwashers using steam may require a especially assembled heat resistant solution.
Corrosion resistance; Copper. Of the 19 identified chemicals or mixes that must not be used with the copper exchanger, 6 are here listed: Acetylene; ammonium; ferric chloride; ferric sulphate (which may be found in some town water); silver salts and mercury.
