Ventilation

stephentbb2000

Finished a new build nearly one year ago, built according to building regulations. Its a concrete build (upstairs bungalow 2400 sq ft) with velux windows. The cavity is insulated according to building regs, with the extra insulated slab internally on the external walls. We have triple glaze windows and a sealed wood burning stove plus solar panels with oil fired central heating.

Our ventilation is via trickle vents on all windows and veluxs, along with a kitchen extractor and 3 bathroom extractors. Usual problems as i now know, the trickle vents are over active in the winter and the opposite in the summer.

Through lack of knowledge we did not go with an updated ventilation system but if possible we would like to change it. Our questions are as follow.

1. Would it be possible to retrofit and would it be a HRV system we would be installing?
2. Would there be much work (disturbance) involved?
2a. Is it possible to seal the trickle vents etc?
3. What would the ball park figure for this fit be, is there grants available?
4. Finally, who do you contact for such work. Living in Cork, any info or further info would be greatly appreciated.

Have a look at passive ventilation ...but you still need some solution to expel your wet air for the wet rooms.

1. yes
2. depends on house layout etc
2a. yes
3. depends on 2 above, no grants available
4. Will pm you details of my retrofited system

Was your house tested for airtightness? If it wasn't I would have this done first so you know that your house is suiitable for hrv (if it isn't air tight enough your mhrv system will simply be a mv system!).
Also, I would investigate other ventilation strategies as mhrv is not always best suited (for a variety of reasons).

Thanks for the info, got a quote for €4500 for the installation of the HRV system from a Galway based company. I wonder how this quote fairs to works other boards members have carried out.

They are doing drawings at the moment.
