Clear pricing
Pick your heater size and your vehicle type. Every price includes the heater kit. Most customers pay exactly the number below.
| Vehicle | S3 (2kW) | M3 (4kW) |
|---|---|---|
| Van | $2,699 | $3,499 |
| Truck, RV, or other vehicle | $3,199 | $3,999 |
Trucks, RVs, and other vehicles cost $500 more. Most of them need the fuel tank lowered so we can add a small pickup tube, called a standpipe, that feeds the heater. That takes extra time, and changing a customer's fuel tank adds risk for us. The $500 covers both.
We confirm your price before we start. If your vehicle needs unusual extra work, we tell you first.
Which size is right for you?
The S3 (2kW) suits most vans and other small spaces. The M3 (4kW) puts out more heat for larger rigs.

Where the heater goes
The 2kW S3 can usually be installed under the passenger seat or elsewhere on the floor of your vehicle.
We find the best spot for the 4kW M3 after we see your vehicle.
Why Espar
Espar heaters give steady heat without running your engine. They also adjust themselves as you gain elevation, which helps them run well in the mountains of Utah and Colorado.
Espar heaters are common in fleet, overland, and commercial vehicles. They have a reputation for lasting a long time, and parts are easy to find.

Quick answers
Diesel or gasoline?
Both. The S3 (2kW) comes in a diesel model (D2L) and a gasoline model (B2L). The M3 (4kW) also comes in diesel and gasoline. We pick the one that matches your vehicle's fuel.
Is it safe to run overnight?
Yes, when installed correctly. We route the exhaust outside and keep the heater's air intake separate from your living space, so it is safe to run while you sleep.
How loud is it?
Quiet inside. Outside, you will hear a faint tick from the fuel pump and a soft whoosh from the exhaust.
