    Hi, hope I have the right section. I'm looking for info/help on what to replace my current oil burner with and hopefully add panels to help save in the future.

    What I have :
    House of 6, 3 adults 3 teens. Urban 24 hour tariff. Most of our electricity is used during the day.
    4 bedroom semi d, wooden frame built in 1999. Original internal oil burner that I can't get parts for anymore.
    Stanley reginald stove with back boiler and 160ltr cyclinder installed 4 Yrs ago.
    New windows & attics were re-insulated 3 Yrs ago.
    BER cert of C2

    So....

    1. I was thinking of replacing old oil burner with either a new external condensing boiler (grant vortex) or internal wood pellet (elly idro)

    2. I was looking into solar thermal panels to save using the immersion during the summer months, then read about solar pv (which i thought would be handy if diverted to DHW & for charging our ioniq ev) and then theres thermodynamic panels, hot water 24/7. Now I'm really confused.

    I'd appreciate help choosing or feel free to recommend an alternative to the above.

    Thanks in advance.

    Chauffe, Marcel, chauffe!


    Lots of questions in there and I can't help you with some of them, but I'm in a fairly similar situation as yourself and here's what I've done.

    - Replaced old 68% efficiency gas boiler with a Viessmann 98% efficiency gas boiler and heating controls. €600 subsidy iirc

    -5 person household with 4 women / girls and we use lots and lots of hot water. Replaced standard 120l cylinder with 360l cylinder. Have pumped hot water throughout the house and have Kingspan 40 tube solar system which provides most of our hot water (March-October about 90%, November-February about 30%) €1200 subsidy. Solar tubes are far more efficient than solar thermal panels. And solar pv for heating water is very inefficient

    -like yourself we have Ioniq :D * €10k subsidy and free public charging. This is the real winner. Charging it with solar PV is very inefficient though, I wouldn't bother if I were you. Public EV charging is still completely free and night rate charging costs just 6.65c/kWh. Get yourself a night rate meter (this is free)!!!

    I'd love to have solar PV, but it makes no economic sense at all. Hopefully we will at some point get a feed in tariff (FIT), it would sure help in the sums.

    * come say hello here linky, we've nearly got 20 Ioniq EV owners here on boards.

    Thx for reply unkel.
    I was actually looking into getting a night meter and you answered the question I wasn't sure of "it's free". I just have to work out what we can use during these hours. Shouldn't be to hard to convert our usage to night time.

    Just from researching I'm almost set on new more efficient oil burner with solar tubes and bigger cyclinder. Just wondering where you got your tubes from and are they all mostly the same quality these days or are there certain branded tubes people stick with.

    As for the ioniq, we are thrilled with it. Delighted I took the jump to ev, even got a mate in work to buy one too and I'll visit that link you posted ;)
