    Hi,
    I'm in the process of buying a house which has an LPG boiler installed. I would like to install a fire/stove with a boiler and also want to install solar panels. Is this possible ? If yes, what do I need to be careful of. I know nothing about plumbing and so would be really grateful for all the advice/help that I can get.

    Thanks,

    Anthony

    a triple coil stainless steel cylinder should do it.

    That way you have no worries. I imagine your intention is to use as little LPG as possible,

    There will obv be a lot more precautions but by having a triple coil cylinder you will have 3 seperate circuits meaning if one goes off line the other 2 are working. In theory it could also mean that the solar will do most of your requirements in the summer(bar heating) and the stove the winter

    The heat exchanger in a gas boiler has small waterways especially if its a newer model and not one with a cast iron heat exchanger. they are generally not suitable for a dual system. The best approach is to contact the manufacturer and get an exemption or advice from techical. If you are determined to mix systems them at the very least I would suggest joining the systems with a neutraliser and fitting a system cleaner ie magnaclean or similar on the return to the boiler.

    If he goes tripple coil he is not mixing systems. That is why i suggested it. Also a stove needs more of a pressure release than a LPG system. IMO you could never mix any of these systems if you wanted so it wont be an issue

    A tripple coil stainless steel cylinder will meet all the critera and will require no maintenace as a plumber will prob advise.

    Good advise, Joey the lips. The flow rates resp. the flow resistance is stated anyhow on all devices, so why not using the calculator.....

    One point about the overkill planned by the OP: All your planned investment has little sale value if it can't pass the energy rating legislation from 2013, demanding the certification of the entire thermal supply system. For DHW earlier, propably becoming Irish legislation this year.
    Try to buy your LPG on the free market, check the yellow pages. The price is about half compared to Flogas/Calor/ etc... well in line with home heating oil (€/kWh).
