Spare Parts & Factory Support


Flanged Heaters

HEAT does NOT maintain an inventory of complete flanged heaters in stock.  All HEAT Flanged Heaters are built to order.  HEAT does, however, maintain a large inventory of tubular elements which are the primary component used to fabricate flanged heaters.   

Standard design flanged heaters are normally available with a two-week lead time.  Custom heaters with custom elements can oftentimes have lead times of six weeks or more—If your process cannot afford to be shut down for several weeks while a replacement heater is being fabricated, consider stocking a spare flanged heater to avoid this potential downtime.

Pumps & Pump Repair Kits

Most pumps have mechanical parts that will wear over time.  Properly maintaining and replacing pump components will help to improve the longevity of your equipment and your process.   

Most repair or replacement components have quick lead times, but specialty pumps can have extended component lead times.  HEAT strongly recommends that you identify the lead times for specific pump’s replacement components and plan accordingly.  HEAT can supply component parts for Dean, MP, Scott, Nikkiso, Tuthill, and many other pump manufacturers.

Electrical Components

HEAT stocks the following standard components:  Disconnects, Contactors, Motor Starters, Lights, Pushbuttons, Switches, Fuses, Fuse Blocks, and Temperature Controllers.  These standard items can be available within one to three days. 

Although many systems have identical components, custom-designed systems oftentimes have special electrical components that are not maintained in inventory.  If your process cannot afford to be shut down while waiting for custom components, it is strongly recommended to keep a stock of spare electrical components on hand.  Contact HEAT for a recommended spare parts list for your system. 


HEAT stocks a variety of instrumentation: Thermocouples, Pressure Gauges, Differential Pressure Gauges, High/Low-Pressure Switches, High/Low-Level Switches, Low Flow Switches, and Over Temperature Switches.  These items are generally in stock and can be available within 1 to 3 business days. 

Custom instrumentation can have significantly longer lead times and should be purchased as backup spares if your process cannot be shut down for an extended period. 

Control Valves & Valve Repair Kits

Typical Valve Repair/Replacement Items: 

  • Valve Repair Kits (gaskets, seats, and packing)
  • Valve Positioners (I-to-P, 4-20 mA actuator)
  • New and Replacement Valves 

HEAT typically does NOT keep these components in stock.  Lead times can be long and can vary by component. If your process cannot afford to be shut down while waiting for replacement parts or valves, HEAT strongly recommends stocking complete replacement valve assemblies. 

Expansion Tanks

HEAT stocks the following expansion tank parts:  Relief valves, Sight Glasses, and High/Low-Level Switches.  These items are generally in stock and can be available within 1 to 3 business days. 

HEAT does NOT stock Reflex Gauges, Back Pressure Control Valves, or Inlet Pressure Regulators.  These items should be stocked as backup spares if your process cannot afford to wait for long lead item components.

Heat Exchangers

HEAT does not stock heat exchangers, however, we do offer replacement exchangers. HEAT maintains detailed records on all heat exchangers provided within our packaged heat transfer systems.   

Delivery of replacement parts or complete replacement heat exchangers can take 8 weeks or longer. If your process cannot afford to be shut down while waiting for custom replacement exchangers, it is strongly recommended to stock a replacement unit.
