    Yeah that seems pretty pricey one thing I had considered was single room heat recovery vents such as this one.
    They are fairly pricey but would consider just putting them in main moist air rooms, i.e. bathroom and kitchen.
    Currently most of the vents in house are blocked up anyway and we just open the windows regularly to refresh the air.

    As an aside to this, Varadkar has said the following from this article:

    'Phenomenal' €50bn cost for retrofitting of all homes - Varadkar
    He said the European Investment Bank (EIB) could play a role in proving long term loans, helping people "upgrade and insulate their homes and then pay that back over a long period of time with the savings they've made from their energy bills. Those models do exist".

    As someone who's hoping to upgrade and insulate next year, I wonder how likely (or how long) it would take for this to be introduced?

    Currently, I know about the SEAI grants, and BOI do a 'Green' home improvement loan at 6.5%, which seem to be the best options at the moment. (We only bought the house last year, so we very likely don't have enough equity built up yet to have an equity release on the mortgage).

    How useful such grants will be is questionable imho.

    Just look at the cost of insulation the attic in an average terrace / semi-d and you'll be quoted around €1200, knock the grant off that and it's still in the region of €800 for a job that a competent DIYer can get done in a day (or over a weekend) for about €200 worth of materials.

    Hi, what all does a BER person do when they arrive to an assessment?

    Ive been involved in renovating houses for a good few years now.

    The BER is a joke.

    We have bough old houses that had a BER of F and got them up to C or B for considerably less than €10K every time.

    Then when you are at B you have to decide if you want to spend twice as much again (plus expensive future maintenance) to save yourself what probably amounts to a couple of hundred euro a year after that.

    Dont believe the money figures that you see on the website for the cost of each BER house either. I am in a D rated house atm and it costs about of €1200 a year to heat. The seai website would have you thinking it costs you €3500 - €4000 per year to heat.

    Thats 6 fills of your 1000l oil tank per year for a 4 bed detached house. What a con that website is :)

    One fill of oil (about €650), possibly into a second if it was a really cold winter, and we would have plenty over at the end of that year.

    But since the oil was getting stolen and we couldnt get gas we went to electric heating and you can see exactly the cost of that on the web app. And thats about €1200 or thereabouts for heating and water for the whole year for a 4 bed detached house, granny flat and garage.

    It was all an exercise back during the crash to get builders off the dole at the expense of homeowners.

    Cost of getting polystyrene beads blown into wall cavities is double the price in Ireland to if you get any company north of the border to come down and do the exact same job.

    Think about that for a minute.

    One room. €500 by the time its installed (Dont forget it probably wont last 10 years, so you will be getting a new one by then anyway).

    They say 4 years payback against a normal extractor fan. Would that be a normal extractor fan on 24hours a day :)

    Considering €500 will heat your whole house for about 6 months or more I dont see you saving that with a heat recovery vent in one room.

    Of course if you were to put one in each room then thats €500 a pop.

    Those figures the BER calculations are based off are purely indicative and are based on something crazy like heating all internal rooms uniformly to 20C 12 months of the year!

    Exactly. And we have thermostats and controllers in each room now that only heat the rooms when needed.

    It would be very rare that a bedroom gets heated during the day and only 16C in the evening.

    Then the other rooms only get heated to about 20C for the times they are used.

    The hall is never heated.
