Combi boiler and water pressure in Dublin 3

    Got a quote from the bord gais man to replace a broken boiler , I asked him about replacing the indirect, HW cylinder system with a combi boiler, he told me that Dublin suffers from low water pressure so a combi boiler is not reccomended (I know that they need a certain bar pressure to work)
    Is that right, does Dublin have water pressure too low for a combi boiler to work?
    Thanks.

    If your anywhere near east wall ,the pressure around there is terrible.

    In parts of england it's the law that people are guarnteed somewhere in the region of 2bar + pressure . Thats why combi boilers are popular in england.

    In eastwall the pressure is something in the region of .5bar and thats not constant.

    Thanks, good to know he wasn't spinning a line, strange that the pressure is so poor, presumably the reservoirs are high up in the nearbyWicklow/Dublin mountians.
    The price he gave seemed pretty good, around 2200 euros, payable over 12 months interest free. In the UK british gas would charge at the very least twice that amount.

    I've a similar thread down the page...no replies (yet):(

    I'm in D7. I'm meeting 3 people this week who specialise in "new" heating/energy systems.

    I really want a combi - makes no sense heating water and storing so ans then not using it! Apparently you can pump your attic tank water to the combi.

    It difficult to get hard facts. I'll post my results as they come in...If you find out anything useful please update this thread.

    You can install a combi and pump the boiler from the attic storage tank. Cabra's pressure isn't too bad ,it's about 1 - 1.5 bar there.

    But in areas like eastwall ,the tanks take an age to fill properly and thats why that option isn't really open there.

    €2200 is expensive for a boiler replacement .I would have thought €1800 is above average for a standard three bed house.

    Make sure you get a good boiler for that price or the free interest will be gone on boiler parts.
