Fantech HERO 150H

At a glance

• In its favour
• Plain fact
• Worth knowing
• Not stated by the maker

• In its favour: HVI-certified (HVI 2505381)Its airflow and efficiency were tested to the Home Ventilating Institute’s standard.
• Plain fact: 150 cfm at 0.4 in., 140 cfm at 0.5 in. of duct pressureCertified fresh air delivered, at HVI’s headline rating point and at the higher pressure many real ducts run at.
• Not stated by the maker: No Fantech CO₂ control documented for the HEROIts D+ and D− input holds maximum speed while closed, so a CO₂ relay there should work electrically. Fantech doesn’t document it: ask first. (Our August review listed Fantech’s CO₂ sensor accessory for this family; Fantech’s manuals don’t show it wired to a HERO.)
• In its favour: Humidity control documented
• Plain fact: How it handles frost in very cold weatherInternal recirculation defrost ('WinterGuard'). It starts when the outdoor temperature falls below 23 °F (−5 °C) and does not depressurize the home.

Certifications

• HVI certified

  HVI 2505381

  The Home Ventilating Institute tested its airflow and heat recovery. The certified numbers on this page come from its directory. Find HVI 2505381 in HVI’s directory

• ENERGY STAR (Canada)

  Listed as HERO 150H

  On Natural Resources Canada’s ENERGY STAR list for HRVs and ERVs, which sets minimums for heat recovery in cold weather and for fan power. ENERGY STAR certifies HRVs and ERVs only in Canada. NRCan’s ENERGY STAR list (search the model number) (checked October 19, 2026)

Would it cover your home?

Tell it who sleeps in each bedroom. It’s checked against the 800 ppm goal the same way the app checks a unit an installer quotes.

Certified airflow

How much fresh air it delivers as the ducts push back. More duct pressure, less air: that’s why the installer’s duct design matters as much as the unit.

Lowest steady airflow (maker)

50 cfm

Highest airflow (maker)

150 cfm

Heat recovery

Sensible recovery (SRE) is the share of heat kept in winter, after the fan’s own heat is taken out. Higher is warmer incoming air for the same airflow.

• Plain fact: Keeps 75–80% of the heat at 32°FAcross the airflows HVI tested.
• In its favour: Tested at −13°F too: 63% SREHVI’s very-cold test point, useful in cold climates.

HRV or ERV: which fits your home?

Turning up on CO₂

A CO₂ control can switch it to a higher speed when the bedroom needs air, then back. HouseExhale’s setting: up at 750 ppm, back at 650, never above 800.

• Not stated by the maker: No Fantech CO₂ control documented for the HEROIts D+ and D− input holds maximum speed while closed, so a CO₂ relay there should work electrically. Fantech doesn’t document it: ask first. (Our August review listed Fantech’s CO₂ sensor accessory for this family; Fantech’s manuals don’t show it wired to a HERO.)

What Fantech documents

• Not stated by the maker: No CO₂ control documented for its home unitsIts CO2RT-R (99315) is sold with its commercial units, and its switch-point range isn’t published.
• In its favour: HERO: a dry-contact input holds maximum speed while closedTerminals D+ and D− (meant for a dehumidistat). A CO₂ relay there should work electrically; Fantech doesn’t document it, and defrost comes first.
• Worth knowing: Never connect 120 V to its control terminalsFantech’s manual says so; a CO₂ relay needs its own 24-volt supply.
• Plain fact: Flex: its boost timers run 20 to 60 minutesA timer input runs its time and stops, rather than staying high.

Four ways to make it turn up by itself

• A CO₂ control on its high-speed inputAsk your installer

  HERO’s D+/D− input holds maximum speed while closed. Undocumented for CO₂: your installer confirms.

• A night scheduleAsk your installer

  A timer on its timer or D+/D− input, or its wall control’s settings.

• Its maker’s CO₂ controlAsk your maker first

  Fantech’s CO2RT-R exists, but Fantech doesn’t show it wired to a HERO or Flex. Ask Fantech first.

• Your monitor and a smart-home relayAsk your maker first

  A dry-contact relay on D+/D−. Not documented by Fantech.

Installing it

The maker’s facts an installer plans around. Your installer confirms them for your home.

Power

120 V, single phase, 1.4 A, 180 W. A 3-foot plug-in power cord with a 3-prong plug.Scope: 1.4 A max also on Fantech's HERO page and in the June 2025 brochure

Duct connections

6 in (152 mm) round metal duct collars with rubber seals, all on top (top ports)Scope: '6" top ports' also in the SupplyHouse and Sylvane listing titles

Size

Height 24 7/8 in (626 mm) × width 27 7/8 in (707 mm) × depth 13 3/8 in (341 mm). The spec sheet adds 23 in as an unlabeled fourth size and recommends 14 in (355 mm) clear in front to slide the core out.Scope: clearance from the 2022 spec sheet

Weight

51 lb (23 kg)Scope: SupplyHouse also says 51 lb (23.2 kg) including core; the 2022 spec sheet says 52 lb (see notes)

Mounting

On a wall with the included speed bracket (wall bracket kit 428546), or hung from the ceiling joists with chains, hook screws and springs (chain kit 404261), kept level. For the 150H the IOM says to move the vibration isolators to the holes shown, and the unit stands upright against the wall.Scope: kit numbers from the 2020 HERO manual parts list (https://www.appliancefactoryparts.com/content/pdfs/291072-1.pdf)

Drain line

Yes: as an HRV it needs a drain line for condensation. The IOM's drain step is 'only necessary for HRV products', and a drain tube comes in the box for HRVs.Scope: family IOM (p. 14); the 150H is the HRV ('Fresh Air Appliance - HRV') per its spec sheet

Cold weather

Internal recirculation defrost ('WinterGuard'). It starts when the outdoor temperature falls below 23 °F (−5 °C) and does not depressurize the home.

Balancing the airflow

Manual balancing using integrated pressure taps

Ducts

Dedicated or simplified central-HVAC integrations per manual

In the box

Casing, collars, terminals, power cord, long wall bracket, washers, wood screws, chains (4), springs (4), hook screws (4), chain screws, sheet-metal screws, drain tube (HRV) and a balancing chart. No wall control.Scope: HERO family box list; SupplyHouse also lists the wall-mounting speed bracket, removable screw terminal and core

Rebates

Federal tax credits ended for work after 2025. Some states and utilities still pay toward an HRV or ERV: rebates by state.

Filters

• Type: Two washable electrostatic panel filters, plus a MERV 8 supply-side filter (the spec sheet calls it both 'integrated' and 'optional')
• MERV: Electrostatic panels are MERV 3 (IOM, product card). Optional MERV 8, MERV 13 and HEPA kits.
• Size: Panels 7.87 × 11.81 × 0.125 in (200 × 300 × 3 mm); MERV 8 supply filter 5.77 × 12.09 × 1.75 in (146.5 × 307 × 44.5 mm)
• Part: MERV 8 kit 428526; MERV 13 kit 428548 (pack of 2); HEPA kit 428551 (pack of 2); electrostatic 428520
• How often: Clean the electrostatic filters, and check or replace the MERV 8 filter, every 3 months or when dirty (2020 manual). The 2026 IOM says check filters every 3 months and the core every 6 months.

Scope: part numbers from SupplyHouse and the 2020 HERO manual (https://www.appliancefactoryparts.com/content/pdfs/291072-1.pdf)

Warranty

Not known yet

What we couldn’t confirm from the maker or HVI. Ask the installer, and get it in writing with the quote.

• A CO₂ control documented for this exact model
• How loud it is

Where the maker’s own documents disagree

• Current: SupplyHouse lists '120V, 3 amps'. Fantech's 2022 spec sheet, HERO page and 2025 brochure all say 1.4 A.
• Weight: 51 lb in the June 2025 brochure and at SupplyHouse; 52 lb (23.42 kg) including core on the 2022 spec sheet. A 2019 Systemair brochure gives a 59 lb shipping weight (
• Filter wording: the spec sheet's feature list says 'Integrated MERV 8' but its filter section calls the MERV 8 optional. Fantech's 150H product card says MERV 3 is the default, with optional MERV 8 and MERV 13.
