dMVHR planning

[Erik79]

We are retrofitting insulation to our Victorian property (2 stories) and we want to install a dMVHR in the kitchen/dining room in the ground floor. It is open plan and the dMVHR will be opposite the kitchen and next to the patio door. Patio door and kitchen window do not have trickle vents.

We also want to install dMEVin the bathroom to try and manage the high humidity levels (semi-basement), there is a window in the bathroom with trickle vents.

Does this plan sound ok? Is there a reason/advantage to go for dMVHR in the bathroom as well?

Only thing I would worry about is the kitchen does not seem to be covered by ventilation?

 

Is the bedroom also having dMVHR? If it is, really confirm noise levels, anything above 30 to 35 may sound noisy in the middle of the night.

 

But I would really concider a simple condition based dMEV setup. Put humidity activated vents near patio doors and in bedroom, these are silent in operation and need no power. Then a dMEV in kitchen and bathroom that runs at all times at a very low background ventilation rate and is automated with humidity sensor to boost only when needed. Greenwood dMEV is silent in operation while doing background ventilation and have a humidity sensor built in.
