HAVA 180H - Horizontally Mounted Heat Recovery Ventilation Unit

HAVA 180H — Horizontally Mounted Mechanical Ventilation with Heat Recovery Unit (MVHR)

The HAVA 180H is a Mechanical Ventilation with Heat Recovery (MVHR) unit that simultaneously extracts air from ‘wet’ rooms while supplying new, filtered air to the ‘habitable’ areas of a dwelling. Designed for horizontal installation, it provides reliable, energy-efficient ventilation with integrated heat recovery to improve indoor air quality and help prevent condensation and mould.

Product Overview

Compact yet powerful, the HAVA 180H delivers efficient airflow performance with very low running costs and thermal recovery to reduce heating demand. It is PCDB and SAP Q listed to ensure recognised performance under Building Regulations. The unit includes a multi-function LCD display controller for easy operation and monitoring, along with automatic summer bypass and anti-frost protection for year-round efficiency.

Key Features and Benefits
