Your winter
Assumptions shown. Diesel and idle-burn figures are sourced; rest pattern and cooler price are our published assumptions — swap in your own. Math assumes the driver bears fuel cost (owner-operators). We do not claim a cooler alone replaces idling for cab heat. The defensible bundle is a cooler plus a fuel-fired cab heater, which burns under a tenth of idling fuel (NRCan).
Fits this use case
VEVOR 5–8kW diesel air heater — the fuel-fired cab heater this page’s assumptions mention: it heats the cab without idling and burns a fraction of idling fuel, which is exactly the payback this calculator prices out.
