HAVA180H Horizontal MVHR Heat Recovery Unit

The Elta HAVA180H 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 86% of the heat through a counterflow plate heat exchanger. It moves up to 59 l/s (212 m³/h), or 49 l/s against 100 Pa.The EPP construction sits in metal casework, with automatic anti-frost protection and an integral summer bypass. It comes pre-cabled with the CTRL-DSP LCD controller and is PCDB and SAP Appendix Q listed, with Elta SAP data up to kitchen + 3 wet rooms. Up to 86% heat recovery Up to 212 m³/h Horizontal, ceiling mounted PCDB and SAP Appendix Q listed What it is best used forFlats and smaller houses with up to three wet rooms plus a kitchen, where the unit has to lie flat in a ceiling void, loft or above a bulkhead.It must be mounted horizontally, so where the only space is a cupboard wall choose a vertical unit such as the HAVA280V.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 HAVA180H adds night mode, holiday mode and a weekly timer on the supplied LCD controller, so occupants can run it quietly overnight without switching it off.The Elta HAVA340H is the larger horizontal unit, moving up to 100 l/s and listed up to kitchen plus 6 wet rooms.Installation notes Mount indoors in a heated space, horizontally on a flat ceiling that carries its weight, using the supplied spacers. It must be completely flat for the condensate to drain. Connect the condensate elbows to a dry trap before waste, so drain smells cannot enter the system, and route the pipe so the access panel can still be removed for servicing. Anti-vibration mounts (not supplied) are recommended. Leave access to the filters, terminal box and inspection door. Connect the CTRL-DSP with a 4 core twisted pair cable up to 30m. A humidity or air quality sensor on the IAQ input raises the speed by 15%. Insulate the ductwork to local regulations, commission the supply and extract rates, and clean the heat exchanger once a year with a vacuum cleaner. 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.
