New House: upgrade and simplify plumbing

    Hi lads,

    we are buying our home (finally!), it is a semidetached house, with gas heating and connection to water mains, located in an estate.
    The house is 12 years old, 3 beds, 3 bath.

    We are now renting a property just opposite, but, since we are originally from Luxembourg, I am not familiar with the standard heating systems that are available in Ireland.

    I would like to upgrade the boiler, simplify the entire system and reduce maintenance to a minimum.

    I plan to install the Honeywell system for zoning via TRV.
    • If I install a Combi boiler= will I get rid of the hot water tank?
    • There is a monsoon 2.0 bar pump installed now, will it suffice for a rain style shower head
    • Can I get rid of the 2 water tanks in the attic? Or is there a better system to manage water? Todays the 2 tanks are just sitting there, without a lid and they look filthy, is the water even safe to drink?
    • I plan to install the filter to avoid sludge forming in the radiators.

    What are my options?

    You can install a Combi and get rid of the hot water tank in the hot press. You have three bathrooms, how many showers or baths? Doubtful you can have two showers at the same time with a combi

    The tanks in the attic are cold water so you need to keep them, they will feed the supply to the combi boiler. They should be covered but in any case you shouldn't drink that water, only from the kitchen taps.

    You can pretty much put in whatever system you want, cost will probably be the limiting factor.

    I dont know the site nor am I qualified to give you advice on those option but I can explain the "two tank" system to you a little bit.

    The two tanks in the attic do not, and are not meant to supply drinking water. The tap at the kitchen sink is normally fed directly from the mains and is meant to be used as the supply for drinking water.

    The larger of the two tanks acts as a reservoir for water used in showers, toilets washing machines etc. Essentially all other cold an hot water tanks in the home. It ensures a consistent pressure and as an added bonus a limited backup supply in the event on mains water or electricity failure stopping pumps etc.

    The hot water tank acts a a buffer for hot water and is a must for solar hot water systems..

    When I bought my house I intended doing the same as you but very shortly after we lost mains water for 3 days but due to the attic tank we at least had water for washing, toilets etc. When it got low I topped it up from a tanker. Since then I changed the tank and actually fitted a larger one, which I was very glad of following the storms a few years back when i had no water for 8 days and no electricity for longer.

    The small tank acts as an expansion and buffer tank for the radiators.. There are number of options for removing that and again advantages and disadvantages to doing so.
