Browse Forums Renovation + Home Improvement 1 Mar 20, 2012 4:36 pm Hi All, We have had some preliminary plans drawn up for an upstairs extension but the upstairs part will be directly over some central heating and evaporative cooling outlets. It will also take up the space where the central gas heating unit is located in the roof. I'm just wondering if its possible to re-run the ducting through the new upper story floor joists to the current outlets and how hard it would be to relocate the gas heating unit. Or whether it is a case of us losing our heating and cooling outlets in the ground floor. Has anyone had any experience with these issues before when building up? Any help would be appreciated. Thanks. Re: Relocating Heating and Cooling when Extending Upstairs 2Mar 23, 2012 10:47 am We looked a this when we were going to extend but chose to re build. One problem is cost. The heating contractor wanted $3k just to remove and refit the old unit, with no guarantee that it would work when re fitted even if it was tested and working prior to removal. And that was just for them to drop it on the ground and I'd have to find somewhere to store it and how to get it there. The placement of the vents will depend on the actual location vs where the unit will st when the upper level is added. You should be able to have the existing vents in the same spots, but will the unit be capable of handling more? Take a look at the following areas and you'll be able to see wheather upgrading the heating and cooling is best vs re locating Cost to remove + refit + store old unit? Age of unit/how much life in existing unit anyway in theory? Space available in new design? (you need to actively make an allowance for it) Size of existing unit (capacity) and ability to handle the extra vents required Efficiency of current unit (this is a big thing) vs Cost to upgrade/increase size to a bigger capacity that will likely be more efficient anyway. The figures from my old heater unit vs the one we got for our rebuild were surprising. The old unit was oversize for our house but it meant we could use it for the extension as well, however the unit we got for our new place (we also got refrigerated cooling) uses about half the gas (on paper) than the smaller and older unit we had.
