Hi Birroc,
I DIY installed a unit from MTD-Solutions back in November in our 70's bungalow so not a new build. But here are my thoughts to date.
- I went for this unit mainly because it only consumes about 20w in normal state (it ramps up when showering etc) and the company were very DIY friendly.
- House is much drier now, no condensation on inside of windows in the morning or in the bathroom when showering. The general dampness that we used to experience when we moved in a few years ago has (so far) gone.
- One feels much fresher in the morning when waking up
- Spiders are no longer in evidence around the house (in case that's important)
- Feels strange not opening the windows anymore
- very happy drying clothes in UT now as moisture is extracted.
- One might miss the hum from the old extractor fans in bathrooms (we don't)
- In our installation a very slight hum can be heard in bed late at night from the air coming out of the vent, but I need to follow up on this as it may be something to do with the way I ran the ducting.
- Total cost came to just over 5.5K and that included all the insulated ducting, vents, clips, tape etc. I believe I could have got it installed for another 500euro not including making the 2 x 6" holes in the wall.
It's very easy to operate, just plug it in and it also came with a remote which enables you to select low, medium or high speeds should you need it from time to time. We leave ours on Auto.
- There is a small maintenance job that must be done from time to time and that is to vacuum the filters
- Initially I thought it was chilling our bedroom but a check with a thermometer showed that this was not the case.
All in all I'm very pleased with the outcome so far.
I know some units allow you to add a little heat which seems like a good idea but I was determined to keep the power usage to a minimum.
That's all I can think of at the moment.
