HAVA120HV Horizontal Vertical MVHR Heat Recovery Unit

The Elta HAVA120HV is a whole house MVHR unit that extracts stale, humid air from wet rooms and supplies fresh, filtered air to living rooms and bedrooms, recovering up to 82% of the heat through an enthalpic counterflow heat exchanger, which recovers moisture as well as heat. It moves up to 32 l/s (115 m³/h), or 25 l/s against 100 Pa.The EPP construction sits in metal casework, with automatic anti-frost protection. It comes pre-cabled with the CTRL-V1 touch controller and is PCDB and SAP Appendix Q listed, with Elta SAP data up to kitchen + 1 wet room. Up to 82% heat recovery Up to 115 m³/h Horizontal or vertical, 171mm deep PCDB and SAP Appendix Q listed What it is best used forFlats, apartments and small dwellings with a kitchen and one bathroom, especially where the only space is a shallow ceiling void: the casing is just 171mm deep and can also be wall mounted vertically.Elta only publish SAP data for a kitchen plus one wet room, and the datasheet lists no summer bypass, so for a second bathroom or en suite step up to the HAVA180H.Why choose this over alternativesMVHR keeps an airtight new build or deep retrofit ventilated around the clock while recovering most of the heat that trickle vents and extract fans throw away, which helps with Part F and the SAP assessment. The HAVA120HV brings this to very shallow voids.The Elta HAVA180H has an integral summer bypass and the CTRL-DSP controller with weekly timer, and is listed up to kitchen plus 3 wet rooms.Installation notes Mount indoors in a heated space, on a flat surface that carries its weight, with at least 300mm clearance for access to the filters and inspection door. On a ceiling, fit the supplied spacers on the condensate drain side so the unit tilts 2° and the 16mm winter condensate drain can empty. Wall mounting is also allowed. Connect the 16mm condensate drain to the drainage pipe through a U-bend, and insulate ducts to local regulations. Anti-vibration mounts (not supplied) are recommended. The CTRL-V1 controller connects with a 6 core cable up to 30m long. Speeds I, II and III are set on dip switches during commissioning. Clean the heat exchanger once a year with a vacuum cleaner and keep the filters clean. You'll also need Elta SEN-HY-I wall mounted humidity sensor wires to the unit's volt free sensor input to boost ventilation when humidity rises.
