Why I Bought It

maXpeedingrods Under-Seat Diesel Heater appears in my build materials and equipment for this work.

I installed the heater beneath the front passenger seat and built a black cover to point its interior vent into the cargo area. The mounting, pipe routing and cover fabrication took several diary sessions.

Fitting the Heater and Making the Separate Vent Cover

  1. I removed the passenger seat, made the floor opening, and sanded, primed and painted around it.
  2. I fitted the heater and worked beneath the van on its connected pipes, filter and pump mounts.
  3. I made the black cover with triangular sides and continued the fuel-pump wire route through a factory floor opening.

My Takeaway from This Job

The sloping seat platform made the separate vent face an important part of the job. I liked the finished black panel, although an awkward screw position left a hole for a larger washer in my follow-up plan; the installation took several diary sessions.

The heater installation included the mounting, connections and a custom interior cover as separate pieces of work.

Product Details And Van-Build Uses

SpecificationProduct Detail
Current ListingB08RD4Y378
Manual ModelsMXR1F split and MXR2Y all-in-one
ReferenceParking Air Heater user manual

The current maXpeedingrods listing links an original Parking Air Heater manual covering split and all-in-one arrangements. It separates the component layout from controller operation and shows the parts belonging to each configuration. That makes it useful for identifying the heater, pump, ducting and control connections before organizing a van heating layout. The split arrangement places components in different locations, while an all-in-one housing groups more of them together. My under-seat heater account remains the record of my own installation; the linked document belongs to the current purchase option shown on this page.

Alternative products

Two Alternatives to Compare

The VEVOR and LF Bros alternatives use all-in-one enclosures with their own tank arrangements. That packaging is different from my under-seat layout with a separately fabricated vent cover.
