Single-Room HRV

KCVENTS single-room HRV ventilators provide room-by-room fresh-air exchange where a central duct network is impractical. Compare airflow, wall opening, heat recovery, controls and filter options, then verify the current datasheet for the required market variant.

A single-room heat recovery ventilator (HRV) is the practical choice when a project needs balanced fresh-air exchange in individual rooms but a central duct network is not practical. Start with the required room airflow, wall construction and control requirements, then verify the selected KCVENTS model's current datasheet before ordering.

Quick answer

Use the product pages below to compare the current VT100, VT125 and VT501 variants. Their ranges and controls differ, so the room design should decide the model.

VT100

Compact wall-mounted HRV with 20–50 m³/h listed airflow and three-speed control.

VT125

Single-room wall HRV with ceramic heat recovery, optional filtration and four comfort speeds.

VT501

Room-scale HRV with remote or WiFi control options and HEPA/activated-carbon filter options.

Current model comparison

Values are a buying guide, not a substitute for the latest datasheet.

Model Listed airflow Heat recovery Control / filtration notes
VT100 20–50 m³/h Ceramic core; product page lists up to 90% Three speeds, sleep mode and removable pre-filter
VT125 See product page variant Ceramic core; product page lists up to 90% Four speeds; pre-filter with optional HEPA and carbon filtration
VT501 See product page variant Ceramic core; product page lists up to 90% Standard remote or WiFi/Tuya options; HEPA and activated carbon options

Specification basis: the linked KCVENTS product pages currently state the values shown above. Confirm airflow at the required external pressure, sound level, filter configuration, electrical variant, test method and test-report revision before a purchase order.

“Consider adding controlled ventilation after you air seal. It may be necessary to provide fresh air to avoid buildup of stale air and indoor air pollutants. Special air-to-air heat exchangers, or heat-recovery ventilators, can do this.”

The Eurovent Certification programme states that the heat exchange efficiency on mechanical ventilation heat recovery (MVHR) systems ranges from around 70% to over 95%, and that whole-system efficiency depends on other factors. This is an industry-review figure commonly quoted in advertising, not a test result for a KCVENTS model; confirm the current datasheet for the exact variant (Eurovent Certification, Mechanical Ventilation efficiency is not only about Heat Recovery).

Single-room HRV buying questions

Plain-language answers help an engineer or buyer prepare a complete enquiry.

When is a single-room HRV better than a whole-house system?

Choose a single-room unit when ventilation is needed in selected rooms, retrofit access is limited, or central ductwork is not practical. Choose a centralized system when one coordinated duct design must serve multiple rooms.

How should I size the airflow?

Use the project's ventilation design and intended room use first. Do not size from floor area alone. Check the model curve at the required external pressure, then confirm noise, wall installation and control requirements.

Does an HRV replace an air-cleaning system?

No. Heat recovery and filtration address different needs. An HRV exchanges indoor and outdoor air while recovering heat; the filter option should be selected separately for the project's outdoor air and indoor-air-quality requirements.

What should be included in a quotation request?

Include room use, airflow, wall construction, target market, voltage or plug, control preference, filter requirement, certification or test-document needs and estimated quantity.

Need a model recommendation?

Send the application, required airflow, wall construction, target market, voltage or plug requirement, certification needs and estimated quantity.

KCVENTS can then confirm the suitable model variant, available controls and the documentation required for your project.
