Where Envi products are made
The Envi 120V, Smart Envi, Smart Envi MAX, Envi MAX and Envi 220V hardwired heaters each carry “made in USA” in their product data, plus the bullet “American Owned & Built — High Build Quality — ISO 9001 Quality Control Factory Certification.”
The EnviPure EP-300 large-room HEPA air purifier and the replacement HEPA filter set both carry “made in USA,” which is what makes this a brand-level claim rather than a single-product one.
Its timeline records that the earlier Econo-Heat/eHeater product was “manufactured abroad” and states that “eheat has no ties to the South African manufacturer.” A company that publishes the imported chapter of its own story is easier to believe about the domestic one.
What this emblem covers. Every Envi-branded product eheat manufactures carries a made-in-USA statement on its own page, and the company describes the heater as “built right here in the USA in a state-of-the-art, ISO 9001 quality certified manufacturing facility.” The plant’s city is not published. The Honeywell and LuxPro thermostats and timers sold alongside the heaters are third-party products and carry no such claim.
The story
The Envi story begins with imported heaters and a living room, which is an unusual thing for an American-manufacturing profile to say out loud. eheat’s own timeline starts in 2000: “I started selling imported heaters from my living room.” In 2002 the company “introduced the concept of flat panel, wall-mounted heaters to North America.”
What it sells now is its own design and its own patent. The Envi is a pure convection heater — no fan, no exposed element, no moving parts. Air enters at the bottom, passes through internal chambers the company calls stacks, and leaves at the top. eheat calls it “the world’s first, and only, 100% pure convection, wall mounted, heater,” and holds US Patent 8,447,176 on it.
The practical consequence is a heater with a surface that sits at roughly ninety degrees Fahrenheit — warm, not hot — which is why it ends up in nurseries, bedrooms and homes with animals. An automatic thermal cutoff and the Wall-Sens™ system, which kills power if the unit is pulled off the wall, handle the rest.
Why they matter
The line has kept moving. March 2023 brought the EnviMAX, the company’s first 1000-watt panel, rated for rooms up to 350 square feet. September 2023 brought the Smart Envi, which eheat says arrived “after 14 years of research & development.” The EnviPure HEPA air purifier extended the brand into a second category, and it carries the same made-in-USA marking as the heaters.
The company is careful about which claims belong to it. Its site sells Honeywell and LuxPro thermostats and timers as accessories; those pages carry no origin statement, and this profile does not extend the emblem to them. A customer review on one of those pages happens to contain the words “made in the USA” — a reviewer’s opinion, not the company’s statement, and not treated as evidence here.
Envi heaters come with a three-year manufacturer’s warranty; thermostats and timers carry twelve months, and refurbished units 180 days. The company is in Houston, Texas, and answers the phone in Central time.

Envi questions
Are Envi heaters made in the USA?
Yes. Every Envi-branded product page carries “made in USA” along with the bullet “American Owned & Built — High Build Quality — ISO 9001 Quality Control Factory Certification,” and eheat says the heater is “built right here in the USA in a state-of-the-art, ISO 9001 quality certified manufacturing facility.” The Honeywell and LuxPro thermostats eheat resells are third-party products and carry no such claim.
How does a fanless heater work?
By pure natural convection. The Envi has no fan and no exposed element; cool air is drawn in at the bottom, warmed as it passes through patented internal chambers, and rises out of the top. eheat describes it as “the world’s first, and only, 100% pure convection, wall mounted, heater,” under US Patent 8,447,176.
Is it safe around children and pets?
The company states the surface runs at about ninety degrees Fahrenheit — “truly cool-to-the-touch” — with an automatic thermal cutoff, and Wall-Sens™ technology that “safely cuts power to heater if it is removed from the wall.”
What is the warranty?
Three years on new Envi wall heaters, twelve months on thermostats and timers, and 180 days on refurbished units.
