Pressurised Cylinder Suppliers

    Hi All,

    I'm at the second fix stage of having a heating system and pressurised water system installed. The cylinder, cold water tanks and boiler are going in a block built shed fairly close to the house. The "business end" of the system has been left until the shed had a proper roof.
    My plumber has quoted for a 300L pressurised twin coil cylinder because I plan on installing solar panels and the additional piping required for them has been installed.

    I figure that since I have the space for it in the shed and if the water is going to be heated for next to nothing for most of the year I should heat as much of it as possible. Initially there will be 5 adults living in the house each with their own bathroom.

    The plumber has also quoted me for a 450L cylinder but he's sure I could get one cheaper myself. He mentioned some place in the West. The 450L was working out at just over twice the price of the 300L! :eek: If I could afford it I'd be better off getting two of the 300L cylinders!!

    If anyone has any thoughts on the above or can recommend a supplier that would be great. :)

    Don't forget that if you increase the size of your cylinder, the area of your solar panels will need to be increased in proportion! Make sure you've enough south-facing roof space before you commit to a large cylinder. There's not much point in having a large amount of lukewarm water that needs to be heated further for it to be of usable temperature even during the best sunny days!

    According to the SEI's latest recommendations, you should allow 50-70 litres of storage per m2 of panel (aperture) area. This would mean you'd need 6.5 to 9m2 of panel area for a 450 litre tank. If you are planning on putting that area of panels on the roof of your shed, it could certainly save you a lot in slating costs if you fit in-roof flat plates!

    As to your actual question (:)), I've seen a 300 litre, dual coil, enameled steel tank online for €1200 + VAT and a 500 litre for €1650 + VAT. From the same place, a 300 litre stainless tank comes in at €2115 + VAT, 500 litre stainless tank at €2680. I wouldn't consider these prices particularly great but not quite twice the price there between the 300 & 500 litre tanks...
