    HI i have recently bought a house that has 4 bed rooms, 2 living rooms one bathroom and one ensuite,kitchn,utility.. and i have had conflicting information from two different plumbers about which type of boiler to get. It currently has no central heating. one has given me a list of combi boilers (

    Around 30kw ones I looked at. Main Eco 30kw Baxi, duo tec 28kw or 33kw Worcester 30i Worcester 32cdi compact.
    and the other plumber says these wont be sufficient and i need a normal boiler and cylinder. help!! confused isnt the word which one should i go for??

    I believe that best practice in a large 4 bed would be cylinder and boiler. Especially if there would be a potential to extend. But I have had home owners ask me to price for a larger combi boiler with a larger hot water flow rate.

    Baxi or Worcester cdi for me depends what your budget is

    Unless your planning to have more than one shower room / bathroom combi

    If you are unvented cylinder

    But this depends on your incoming flow and pressure

    Combi 15lpm and 1.0 bar min

    Unvented 25lpm and 2.5 bar min

    Hello Daro,
    May I suggest you get a Heating Engineer round to assess and price it.

    He/She will be able to calculate the Heating /Hot Water requirements for your property and determine the correct size of Boiler

    They will also be able to measure the water main, pressure and flow and give Professional advice on what would be the most suitable Domestic Hot Water system, for you, your property and the people who live there.

    At the stage you are at, you are in a position to ensure you will be happy with the system you end up with for years to come.

    I think you should go for a Worcester boiler as these comes in LPG, gas, and oil fuel and will be within your budget and suit your home.

    Standard condensing wall boiler with unvented cylinder incorporating an off-peak immersion heater and facility to incorporate a solar panel. Have the controls fitted that will give you hot water priority.

    If you have a good pressure mega flow is the best option you will also have a hot water back up.
    But it's a bit expensive then Combi system, work with your budget.
