  • Reverse Cycle Heating & Cooling

    To start with I know buggar all to do with heating and cooling, I have ducted gas heating in my house with vents in the floor and am thinking of getting a split ducted cooling system with the ducts in the ceiling but they all come with reverse cycle heating and cooling.
    My question is should I keep my existing ducting heating which is a vulcan and is around twenty years old or renew it, or go with the rerverse cycle in the new cooling unit.

    Reverse cycle heat or a Heatpump as we call it are great when the temperatures are cool (above zero C or 32F) in very cold areas they are not the best choice.

    You would have to run your utility cost numbers to see if it would be an advantage for you but you could keep the gas heat and have the reverse cycle heat and set up whats called a hybrid system that uses one or the other dependant on the outdoor temperature.

    Heatpumps have come a long way:-)

      This Sanyo split ducted system is cooling only. http://www.sanyohvac.com/products.php?id=36UW72R

      The heat pumps really have come along way. They have decent performance down in the teens now. Its rare to find a mini-split that has back-up electric heat, anymore.

        When I worked overseas we installed "Chigo" brand non ducted mini splits.

        I gotta say they were the tuffest units I have ever seen!

        I forget how much different the equipment can be in other parts of the world....

        I never would have believed that any contactor made by Telemecanique could handle their rated amp draw until I worked with them overseas...LOL

          Thanks for info the sanyo web site was vary helpfull with the installation manual but here is another question I have access in the roof over my house to install the duct the concealed Duct type unit but cannot get ducts into the rear of my house as it has a flat metal roof so can I put a concealed ceiling mounted type unit there and connect the two indoor units to the outdoor slit system.

            I dont see where the concealed duct types are used in the multi-split configuration, only single split. I'd consider a wall mounted single for the back room. The smaller units can be purchased for under $1500. Real reasonable IMO.

            I just installed this unit this week and fired it up today. http://www.sanyohvac.com/products.php?id=26KHHS72R The homeowner is beside himself with how nice the unit is.

            Sanyo is using a 5/16 connection on the service ports of their 410a units. Pissed me off I had to make a run to the supply house to get a 1/4 x 5/16 adapter so I could hook up my nitrogen.
