CogenS™ — Hot Water Heater Module
Optimize Your Hot Water Heater Selection
Compare electric, gas, heat pump, and solar domestic hot water heaters from leading manufacturers with complete lifecycle cost analysis. Make data-driven decisions backed by real equipment data.
Why CogenS™
The Right Heater for the Right Building. Proven by Data.
Selecting a domestic hot water heater involves balancing upfront cost, energy efficiency, fuel availability, and long-term operating expenses. The lowest-cost heater today may cost significantly more over its 15-25 year lifecycle.
CogenS™ replaces guesswork with engineering-grade analysis. Compare heater types and manufacturers using real equipment data, local energy rates, and climate-adjusted load profiles to find the optimal solution for any building type.

Why It Matters
Solving the Hardest Parts of DHW Selection
Heater Technology Selection
Choosing between electric, gas, heat pump, and solar DHW heaters requires understanding how each technology performs under your specific load profile and climate conditions. CogenS™ simulates all options with real manufacturer data.
Energy Rate Complexity
DHW energy costs depend on complex utility rate structures -- TOU rates, demand charges, tiered billing. CogenS™ models your exact tariff structure to accurately project lifetime operating costs across technologies.
Lifecycle Cost Visibility
The cheapest heater upfront is rarely the cheapest over 20+ years. CogenS™ reveals the true total cost of ownership including energy, maintenance, replacements, and efficiency degradation over your full study period.
