    I also have another MVHR question, I have a large house -600m2 and it will possibly need two domestic MVHR systems to provide the correct amount of supply/extract air
    supply is 403 and extract 540, is this the correct approach or should I be looking at a commercial MVHR unit?

    thanks for the advice Mark, I did notice the dB of the unit, and was not aware there was a PH requirement for noise, so that is useful to know

    Thanks for your prompt reply Mark, yes it is a garden office, so one or two people at the most and only in the day time
    and the challenge has been to find a unit that small enought not to produce over ventuilation
    what's your view on single room units such as the vent axia HR 25 – could this do the job?

    the client is looking to try for passivhaus certificaiton so at the moment MVHR is the option being considered

    thank you Alan and Nick for you comments- do you think that summer bypass should be specified in houses where is there more air volume and I assume more heat loss?

    On another but similar subject, I have a scheme which has a planning restriction on opening windows- so overheating is a big problem, do you have any suggestions.
    We can use passive stack, but this is not getting the air changes in SAP or we could over size the MVHR and use this, which works in theory, but I'm worried it will be noisy and drafty in practice, or we could use a centralised extract system but then lose the heat

    Are there any other solutions?
