DOMESTIC COIL (OPTIONAL)
Principle of the Domestic Coil
The domestic coil provides a method of heating water indirectly through water-to-water convection. This
method of heating needs to be planned from the initial stages of purchasing your HEATMOR™. A HEATMOR™
Outdoor Furnace must be special ordered and manufactured with a special hole at the back of the furnace to
accommodate the domestic coil.
Operation of the Domestic Coil
The coil is inserted at the rear of the furnace through a hole in the water jacket and fastened by nuts and bolts.
The domestic coil plate is sealed to the outer face of the water jacket by a sealing gasket. As water passes
through the domestic coil, the water in the water jacket heats it.
Maintenance / Result
•
Make sure a tight seal is maintained between the coil plate and the outer face of the water jacket.
•
Firmly fastened connections are essential to ensure there are no leaks.
•
The pH level of the water treatment is important to assist in corrosion control. Low water treatment
levels could lead to domestic coil pinhole leaks. This would allow the water to mix together causing
contamination of domestic water and pressurization in the water jacket resulting in water spillage.
Removal and Replacement
If you suspect you have a leak or faulty internal coil requiring replacement, contact your local dealer.
