Webasto replacement heaters restore heating performance to a vehicle already fitted with a Webasto system, using genuine components engineered to match the original unit. VMACS stocks replacements across the complete air and coolant heater line-up. Air Top 2000 STC, EVO 40 & EVO 55 cabin air heaters in diesel or gasoline with air heating capacities ranging 3,400 BTU to 12000 BTU. Diesel versions of Thermo Top C, Thermo Top EVO, Thermo Pro 50, Thermo Pro 90, Thermo Pro 150 with coolant heating capacities ranging 17,000 BTU to 51,000 BTU.
These are heater-only replacements — no mounting hardware, ducting, or fuel system components included — so plan to reuse your existing kit hardware or source additional parts separately.
See our Webasto High Temp Cabin Ducting collection for ducting, or browse Replacement Parts by Webasto Model for fuel, electrical, and control components matched to your heater. For the full Webasto lineup — including Air Heater Kits and Coolant Heater Kits — or a cross-brand comparison with Climate Command Heaters, keep browsing.
