LIMITED  WARRANTY 

Warranty Coverage for Residential  Installation. 

Thermo 2000 Inc. hereby warrants to the original residential purchaser that the DTH 
tank installed in a residential setting shall be free of leaks during normal use and 
service for a period of fifteen (15) years from the date of purchase as long as the 
original residential purchaser owns the home in which the unit was originally 
installed. Residential setting shall mean usage in a single-family dwelling in which 
the consumer resides on a permanent basis. Also, residential setting shall mean use 
in multiple family dwellings in which one (1) DTH tank is to be use in only one (1) 
dwelling.  In the event that a leak should develop and occur within this limited 
warranty period due to defective material or workmanship, such leak having been 
verified by an authorized company representative, Thermo 2000 inc. will repair or 
replace at our sole option the failed unit with the nearest comparable model at the 
time of replacement.  
 

The 

original residential purchaser is responsible for all costs associated with the 

removal and reinstallation, shipping and handling to and from manufacturing plant.  
The replacement unit will be warranted for the remaining portion of the original 
Warranty. 

 
 

Warranty Coverage for Commercial Installation. 

Thermo 2000 Inc. warrants to the original purchaser that the DTH tank installed in a 
commercial setting for fifteen years. 
Commercial setting shall mean use in other than residential setting stated above in 
the residential setting definition.  In the event that a leak should develop and occur 
within this limited warranty period due to defective material or workmanship, such 
leak having been verified by an authorized company representative, Thermo 2000 
inc. will repair or replace at our sole option the failed unit with the nearest 
comparable model at the time of replacement.  

 

The 

original purchaser is responsible for all costs associated with the removal and 

reinstallation, shipping and handling to and from Manufacturer.  The replacement 
unit will be warranted for the remaining portion of the original Warranty. 

 

 
Limited two years warranty on all D
TH components & 
parts 

All other DTH components & parts are warranted for a period of two (2) years 
against defects due to defective material or workmanship.   

The 

original purchaser 

is responsible for all costs associated with the removal and reinstallation, shipping 
and handling to and from Manufacturer.  The components, repaired or replaced are 
warranted for the residual period of the initial warranty on the unit. 

 

 
Exclusions. 

This warranty is void and shall not apply if:
