Cooling incoming air for the mvhr

[Russell griffiths]

 

I’ve got a pre heater fitted on my mvhr ducting on the fresh incoming air, I’ve decided to run cool water through it from the cool water that’s going through the floor, it’s dropped the incoming air temp by 10 degrees. 
 

what’s your opinion 

worth doing ?

should I ramp the mvhr to push the air around quicker 

or is it a bit pointless as mvhr moves so little air about I’m wasting my time. 
 

thoughts people.

I would consider it generally rubbish due to low flow rates for cooling. 

 

However you can look at a different way as a dehumidifier to the incoming air. This will actively reduce house humidity and allow more margin from dew point for UFH (cooling), so you can run it cooler with no dew point issues.

You most likely start making water at the heat exchanger, so will need to add some form of drain.

Ah you think we might get condensation inside the heater box thing. .?
