Piping Diagrams

Steam Boiler: HeatSponge Diagram 100-Rev A:

This is a piping diagram for the typical installation where the HeatSponge is located between the boiler feedwater tank, either a deaerator or feed tank, and the boiler.

 

Steam Boiler: HeatSponge Diagram 300-Rev A:

This is a piping diagram for using a circulator pump to circulate water fram a tank, through the HeatSponge, and return to the same tank.

 

Steam Boiler: HeatSponge Diagram 500-Rev A: 
This is a piping diagram for an installation where the HeatSponge is located between the softener and the boiler feedwater tank. This installation is utilized when the economizer is used to heat raw make-up water.

 

SIDEKICK-RAINMAKER Hot Water Boiler in a Primary-Secondary Loop:
HeatSponge Diagram 900-Rev A:

This is the most basic piping diagram for installing a condensing economizer in a hot water system with a secondary pump. This utilizes a Thermostatic Bypass Valve to blend high temperature supply water into the return to protect the boiler from shock or condensing from primary loop cold water exiting the HeatSponge condensing economizer. The supply temperature will still be above condensing and will blend into the primary loop so offers no control of supply temperature. The boiler will always operate at safe non-condensing temperatures with the HeatSponge handling the aggressive condensing.

 

SIDEKICK-RAINMAKER Hot Water Boiler in a Primary-Secondary Loop:
HeatSponge Diagram 944-Rev A:

This is an advanced piping diagram for installing a condensing economizer in a hot water system. This utilizes a Three-Way control valve and secondary pump to both blend high temperature supply water into the return to protect the boiler from shock or condensing from primary loop cold water exiting the HeatSponge condensing economizer as well as blending the relatively cold water into the high temperature supply leaving the boiler for precise control of the supply water entering the primary loop. The boiler will always operate at safe non-condensing temperatures with the HeatSponge handling the aggressive condensing.

 

HeatSponge Condensate Drain P-Trap Piping;Rev 3:

This is detail of the P-Trap required on nearly all HeatSponge installations.
