The STG Story
At STG Heating , we believe that heating and thermal systems should be engineered as complete systems—not simply assembled from individual products.
01

Application First, Equipment Second

We do not begin with a product. We begin by understanding the application.

02

Design for the Real Operating Condition

A system that performs well only at design conditions is not necessarily a well-engineered system.

03

Energy Efficiency Through System Engineering

Energy efficiency is not achieved by selecting an efficient piece of equipment alone.

04

Reliability Is Designed In

Reliability is a design parameter—not an afterthought.

05

Right-Sizing Rather Than Over-Sizing

Over-sizing can be as detrimental as under-sizing.

06

Integration of Technologies

We believe in selecting technology based on its suitability to the application.

07

Safety Without Compromise

Thermal systems involve combustion, pressure, high temperatures, electrical power and stored energy. We, therefore, treat safety as a fundamental engineering requirement.

Engineering Philosophy

Seven tenets that shape us.

S. Trivedi

Founder & Chairman

40 years in thermal engineering. IBR-certified inspector. Author of three internal standards on combustion tuning.

R. Mehta

Managing Director

Mechanical engineer, IIT Bombay. Led the company's transition from steam-only to multi-modal thermal systems.

A. Iyer

Head of Engineering

Specialist in thermic fluid networks with over 120 commissioned process plants across pharma and food industries.

K. Shah

Director, Service & AMC

Built the nationwide service backbone covering 18 states with 24/7 response SLAs and preventive maintenance programs.

Leadership
