Ductless HRV

    I am looking to solve a heating and ventilation problem in a basement property by installing HRV to extract warm humid air from an internal bathroom and bring in fresh air. The challenge is trying not to disturb the internal finishes by running ducts in and out.
    I have read a little about ductless HRV units that are fitted to windows and wondered if anyone knew about them.
    While the bathroom is about 5m from the window in reception area I was hoping that 24/7 ventilation through window might help
    Currently basement has mould in places

    Is this like a Mitsubishi Lossnay unit?

    I think you need to consider the path of air, and the content of that air.

    The typical guidance is to extract directly from the bathroom as that is the source of both steam & odours. So you shouldn't want that air passing through other areas...

    Constant extract from the bathroom should help for sure - you can get multi-speed extract fans with presence or humidity controlled boost - I think Vent Axia have them.

    just be aware of noise (e.g. try get the quietest once you can)

    Is there ducting from the bathroom to atmosphere already you can use?

    And would you use the window area as air inlet?
