I got a unit from <SNIP>, in the curent climate they are mad to do business and you can bargain with them on price.the thing you have to ask yourself is, are you sourcing the unit,ducting etc.do you install yourself or get someone elso to do it.to many cooks spoil the broth!

plus no one can comission the unit for you and if it goes wrong,then the fun starts.you may save in the short time but 9 times out of ten you will pay for it down the road.

no connection with <SNIP> but just found them easy to deal with and knew what they were on about.I am building an airtight timber frame house at the moment.hope this helps.

Edit: Names by PM only please.

Just turn it off in the summer and open all the windows you want?

Very true. HRV units are more about saving energy when your heating is on over the winter not about locking up the house on a warm summer day.

Actually, security is sometimes sold by HRV suppliers as a point in their favour. You can maintain adequate ventilation while keeping windows tightly shut.

Another point, if the correct filters are fitted the HRV unit can remove pollen from the air which benefits hay fever suffers and asthmatics. In this case, all windows and doors should be kept closed so all air to the house is passed through the pollen filter in the HRV unit.

Most HRV units allow the heat recovery part to be switched off or bypassed during summertime if required.

Windows and doors should always be kept shut when the HRV is running, otherwise it is pointless and a waste of electricity.
The filters on mine were filthy and black after a few months running and full of insects and other crap.
It makes a big difference to indoor air quality.

Could you also pm me suppliers too.

dont forget to price in the bI-yearly replacement of filters, or if you can get a unit that allows the filters to be cleaned. I have heard some horror stories recently on the actual cost of some of these filters, and if u don't replace or clean them, your air quality into house can be degraded.

A HRV system should be installed primarily to ventilate a house that is well sealed and is well insulated. Such a house will require relatively little energy to heat it. The HRV system will reduce this further. How much will depend on the efficiency of the unit, type of ducting, standard of insulation along the air tightness and insulation. Imo it would be wrong to install a HRV system alone just to reduce your heating bill.

In the summer you have the option of turning the unit off and opening the windows.

Most system suppliers suggest that filters be changed annually or even more frequently depending on usage of the system, the location of the house relative to pollutants and the number of people in the house. If they are not changed you could end up with a horror story as suggested by Tred earlier.

Hi folks
Looking at the different hrv units for my new build. So if you could pm me details I'd appreciate it. Down the road I was planning on fitting a sauna. A lot of the units dont seem to be able to handle this hot air/steam? Can anyone advise on one which does? or what should I do in this case?
cheers
