A Water Heater Like No Other
Engineered To Last
Economically Heating Large Volumes of Domestic or Process Water
The life of the heat transfer coil is far longer than the tubes of a direct fired system and can be replaced at a small percentage of the cost. The indirect heating principle definitely decreases the maintenance cost of cleaning and upkeep.
Our Indirect Heater is available with all type 316 stainless steel water-ways for deionized or pure process water applications. Note, unit outputs are reduced, consult factory.
Natural Thermal Circulating!
Key Features & Advantages
Parker Indirect Water Heaters eliminate any possibility of flue gas condensation which will occur on Direct Fired Heaters. Sweating and external corrosion of the Boiler Structure and tubes is essentially eliminated. The possibilities of scale, rust and corrosion are minimized by the indirect design principle. The furnace remains at a steady uniform temperature which results in high combustion efficiency and lower fuel consumption. This principle has proven more efficient and provides for a longer life as opposed to a direct system.

A Closer Look Inside
Low NOx Premix Technology
Parker Boiler's fully modulating variable speed low NOx burner systems offer digital electronic set point control, VFD blower for reduced electrical energy usage, precise fuel/air ratio control with no linkages, cams or FGR valves. The simplicity of the System with no FGR fan or valve, allows normal boiler operators to adjust and service the System. Our heavy duty premix metal fiber burners not only provide the lowest emissions possible but also provide long durable service life.
Advantages to having a Low NOx Boiler
• Parker heavy duty premix metal fiber burners.
• Burners provide the lowest emissions possible with a long durable service life.
• Variable Speed Blowers for electrical energy savings.
• Fully modulating variable speed Low NOx Burner Systems offer many advantages.
• Extremely Low NOx & CO levels are attained by our Premix Burner System.
• NOx levels below 20 PPM at 3% O2 and CO levels below 100 PPM are easily obtained.
• Many 12 PPM units are on line with special burners.
Custom Built For You,
Designed For Your Needs
Every Boiler is built with our customers needs first.
The Parker Boiler WH Model Indirect Fired Water Heater is an excellent choice for Low or High Temperature applications. An advantage to owning a Parker Indirect Water Heater is the furnace remains at a steady uniform temperature which results in high combustion efficiency and lower fuel consumption. This principle has proven more efficient and provides for a longer life as opposed to a direct system.

Why Choose Indirect Heating
The Basic Principle of indirect heating is accomplished by circulating the low temperature (or circulating process water) water through a copper tube heat transfer coil which is mounted internally and immersed in the primary Boiler water. The primary Boiler water is contained in a Bent Steel Tube Bundle and is heated in the furnace area, it rises to the upper header where the heat transfer into the secondary water occurs. The colder secondary water does not come into contact with high furnace temperatures or into contact with the flue gas at all.
Corrosive Environments
Our boilers are available with stainless steel cabinets for installation in corrosive environments.
