KitCOG™ Fuel-Saving Simulator

Method & assumptions

Heat recovery model. The recommended kit and its nominal recoverable heat (kWt) are read from the official Termogamma kitCOG™ STD table and linearly interpolated within each kit's GenSet application range. The energy balance is consistent with a GenSet electrical efficiency of ~35–43% and a thermal recovery of ~50–55% of fuel input. The GenSet is assumed to run at its nameplate electrical output during its declared working hours.

Operating hours. Both the GenSet and the existing boiler are described by their own working days per year and working hours per day. The savings calculation uses the overlap between the two profiles — i.e. min(GenSet hours, Boiler hours) — because heat is only recovered when the engine is running and there is a boiler demand to be displaced. The two individual totals and the resulting overlap are shown on the input panel.

Heat coverage. The customer's average heat demand (kWt) is entered directly. The kit covers up to its rated thermal output: if the demand exceeds the kit, the existing boiler continues to provide the remaining gap; if the demand is below the kit, the excess heat is dissipated and produces no saving.

Saving calculation. Useful heat per hour = min(kit kWt, customer demand kWt). Annual saving = useful heat × effective overlap hours, divided by the fuel input that the existing boiler would have needed at its declared efficiency. Default boiler efficiency 85% (typical oil/diesel boiler).

Partial load. When the GenSet routinely runs at partial load instead of nameplate output, the recoverable heat scales down proportionally. In that case the savings shown here should be considered an upper bound; a site‑specific load profile is required for an accurate estimate.

Scope of this simulator. The figures shown above estimate the fuel and the operating cost that the kitCOG™ can save on the customer's existing boiler. They do not include the cost of the kitCOG™ kit itself, nor the cost of installation, on‑site piping, electrical and mechanical connections, secondary pumps, transport, customs duties, VAT, paperwork or commissioning extra‑days. Those items are quoted separately in Termogamma's commercial offer.

Disclaimer and limitation of liability. This simulator is provided for feasibility‑screening purposes only and is intended exclusively for the recipient's internal evaluation. The figures it produces are non‑binding estimates based on (i) Termogamma's official kitCOG™ technical documentation, (ii) the inputs entered by the user and (iii) standard fuel calorific values published by recognized industry sources. No representation or warranty, express or implied, is made by Termogamma Energy Solution Sagl, its affiliates, dealers, agents or distributors as to the accuracy, completeness, fitness for a particular purpose or achievability of the fuel savings, fuel consumption, CO₂ reduction or any other figure displayed. A binding commercial offer requires a site visit, the customer's verified heat‑demand profile and a review of the GenSet datasheet, and is subject to written acceptance of Termogamma's general terms and conditions of sale.

Taxes, duties & jurisdiction. Any amount shown is net of any tax, duty, fee or charge of any nature levied by any competent authority. Nothing in this simulator shall be construed as tax, legal, financial or engineering advice.
