    Central heating

    Our heater has given up the ghost(Gas wall heater, Tall with slats).
    SHMBO wants central gas heating installed at a cost of about $4000 fully installed. Our house is about 80 to 90 yrs old, It has insulation in the ceiling but not the walls. One bedroom, lounge, hallway and kitchen are plastered but the rest is the original lining boards(drafty). We have 11 ft ceilings. What do you guy's reckon will it reduce our cost's or add to them. with the current heater when we opened the hall door or the door out to the back of the house(to back door, bathroom, laundry,toilet) we lose all the heat very quickly. I want to know if central heating is as good as she has been told.
    So give me your opinion and we(she) will decide from there. Thanks in advance Brett & Trudie

    It will cost more to run if you heat the whole house, but if you are getting a modern and smallish unit, AND you have it set up so it has 2 heating "zones" for example "lounge and kitchen only" and "whole house" you could end up saving a little bit if you only use it to heat the lounge and kitchen.
    The newer condensing central heaters are much more efficient than your wall furnace was, but if you are heating a larger area, then it will use more gas.

    Hope that helps,

    I disagree that it will cost more to heat because you will be heating the whole house (if you put registers in each room) you wont have cold rooms and try to compensate for this by overheating one room.

    I have gas central heating and live at 3500 ft asl. I am fortunate in that I have a well insulated house - roof ext and int walls however it is a weatherboard house. We don't over heat the house, basically we heat to 16 C during the day and turn it up to 18 C at night. Turn it off when we go to bed. We are comfortable. We do not walk around the house naked though.

    Our winter 1/4 gas bill is about $450-$485. That is with gas cooking and hot water, 3 bdrm with 9ft ceilings and an open loft.

    So, from my experience it is a most economical way to heat the home. Just depends on how you use it as to how much it costs to run.

    As I understand it he currently only heats one room, with the door closed.
    If this is the case, then heating the whole house, unless the current heater is a terribly, terribly inefficient, can't possibly be cheaper, there is also the lack of insulation in the rest of the house to take into consideration.

    PS. I have Central heating and love it.

    Cheers,

    I do not live in on the coast. It snows where I live regularly. I would feel bad if I lived on the coast and had an electric bill like that.

    I have a single zone system. I don't over heat any one room and I don't lose heat to other areas because it is all heated evenly. I don't have to worry about keeping doors closed. Because the house is heated evenly I can set a lower temperature.
