DOE 81% Efficient Requirements Mandated for 2023 Heater Production

Heatco is expanding its product offering to include 81% efficient furnaces beginning January 1, 2023. This product expansion is to support customers with a desire to meet the new Department of Energy (DOE) requirements for product efficiency. The minimum efficiency requirements for ANSI and CSA standards are not changing, and we will continue to offer our 80% efficient products for the first six months of 2023. The prices for both options will be the same. The 81% efficient products will have slightly different dimensional requirements than the current 80% efficient products. Drawings for our 81% efficient furnaces will be available on our website beginning in January 2023.

Beginning January 3, 2023, all quotes, submittals, and drawings (if available) provided will reflect the 81% efficient product line unless you specifically request 80% efficient furnaces. To properly configure an 81% efficient heating solution, we must know the desired maximum temperature rise for the application.

Initially, 81% efficient products will have longer lead times than our 80% efficient products. Our goal is to have common lead times beginning in March 2023.

Below is a brief description of the changes reflected in our 81% efficient products, and their lead times:

HMA / HDA OEM Insert

- 44” insertion depth is reduced to a 42” insertion depth.

- Shortened tube support brackets dictate reduced clearances for our 81% efficient product offering.

- Minimum temperature rise increases from 20F to 30F.

HMB / HDB OEM Insert

- 180 – 400 capacities will transition to an exterior flue box (vestibule panel grows 1.5” in height)

- Shortened tube support brackets dictate reduced clearances for our 81% efficient product offering.

- Minimum temperature rise increases from 20F to 30F.

HMG / HDG OEM Insert

- Shortened tube support brackets dictate reduced clearances for our 81% efficient product offering.

- Maximum temperature rise increases from 80F to 90F.

- Minimum temperature rise increases from 20F to 30F.

HDA, HDB, and HDG Style CK, CS, CN, CW, K, S, N, W

- Reflect all changes listed above, in addition to adjusted vestibule and cabinet dimensions

Racks

- All dimensions for the 81% efficient racks will change slightly.

- The HDB-HH racks using 400,000 BTU furnaces and below will be most affected. They will grow approximately 1.5" in height per furnace.

HE/HF “Drum and Tube heaters”

- HE/HF 0250 – 0500 will be discontinued on Jan. 1, 2023 (Use comparable HD furnaces).

- HE/HF 0750/1750 will include additional tubes but will stay the same physical size as the 80% efficient furnaces.

- HE/HF 1000/1500/2500/3000 will include additional tubes and increase in insertion depth.

- HE/HF 2000/4000 will experience no changes.
