Solar Hot Water Systems
Schematics and Parts Lists
(Revision 1.0 - May 2011)
IMPORTANT INFORMATION
Diagrams are conceptual only and not to scale.!Final system design must adhere to all relevant codes,
regulations and guidelines and may require the approval and stamp of a licensed engineer. It is the
responsibility of the installer/contractor to ensure that the system design meets all relevant standards,
regulations and guidelines and is safe and operating correctly. Any installer/contractor must be legally
certified to install solar water heating systems and have attended an accredited Apricus training
session before completing the installation of any Apricus products.
The installation of Apricus products must be in accordance with guidelines outlined in the latest version
of the Apricus installation manual.!For the latest version of the manual contact your local Apricus
agent or email offi[email protected].

Naming Convention Overview
Apricus uses the following format coding to describe the systems in this document:
NAME_TYPE_EXHE_TUBE_1STTANK_2NDTANK_EXTBOOST
The following information describes the different options.
NAME: This describes the type of system
!
!APSS - Apricus solar system
TYPE: This describes the type of system being installed
!DIRECT !! - Direct flow solar thermal system
!CLOSED !- Closed loop solar thermal system
EXHE1: This describes the type of external heat exchanger
!BPHE! ! - Dual wall brazed plate heat exchanger with leak detection
TUBE: This describes the number of tubes installed
!AP-30! ! - One AP-30 collector with 30 tubes total
!AP-60! ! - Two AP-30 collectors with 60 tubes total
1stTANK: This describes the type of tank the solar thermal system is connected to
!FTD! ! - Direct flow tank (no heat exchanger)
!FTB! ! - Internal coil tank
!FTW! ! - Dual internal coil tank
!DT-XXX!! - Tank has a dip tube solar connection
!XXX-E! ! - Tank has an electric element
2ndTANK1: This describes the second tank in series in the solar thermal system
!STD-E! ! - Standard electric water heater
!STD-G! ! - Standard gas water heater
EXTBOOST1: This describes the type of external auxiliary heating
!PBGT! ! - Tankless water heater
!TBGT! ! - Top boosted by pumped tankless water heater
!TBGB! ! - Top boosted by indirect boiler
Example:
APSS_CLOSED_BPHE_AP30-DT-FTD-PBGT:
!Apricus closed loop solar thermal system with external heat exchanger, one AP-30 with a dip tube connection to a standard tank
feeding a tankless water heater.
Notes:
1. Depending on the type of system this position may not be filled.
