No ducted systems need a cavity to be installed in, in a ceiling we need 1.5m a the apex of the ceiling to be able to install a ducted system, and under the floor we need a minimum of 700mm to the bottom of the floor joist to be able to install a ducted system.
Ducted systems work best when you have one even temperature across the whole house. There are “zone systems” which are available to assist in controlling the temperature in each room, but they do so by manipulating the amount of air flow going into each room through and electronic damper.
This can have an effect on the temperature of the room, but is not true temperature control of each room.
Yes, heat pumps are about the only form of heating that will meet the healthy homes standard.
Make sure your heat pump is in the correct mode (heating or cooling) if you have just turned the heat pump on for the first time during the heating or cooling season, you will need to give the unit a couple of minutes to make sure the refrigerant is flowing correctly. It may take up to 10-15 minute for the unit to start up properly.
Don’t switch the unit on/off or change the mode from heating to cooling and back, this will only delay things longer.
Back to back installation is when the indoor unit is installed on an exterior wall and the outdoor unit is install on the ground directly behind the indoor unit. This is the most basic type of installation.
When the indoor unit is on heating, the outdoor unit is on cooling, the outdoor air will condense on the outdoor unit copper coil, which turns to water and drips onto the ground.
No, a single high wall heat pump is designed to heat a single room, once that room reaches temperature the heat pump will lower its output to maintain the temperature. Even if you get the biggest heat pump you can, it will only heat/cool the room that it is in.
We do not recommend installing heat pumps in hallways, as they will only heat/cool the hallway properly. Leaving the doors open will mean a small amount of air travels into the bedrooms, but once the hallway has reach temperature, the heat pump will lower is output to maintain the temperature in the hallway.
Yes, heat pumps are the most cost effective form of heating available (other than free fire wood!). From every 1W of electricity you put in, you will get about 3.5-4W of heat out of a heat pump.
Short answer, it depends. If you are home all day, you don’t want to be turning your heat pump on and off constantly, a heat pump uses the most power during start up, so if you turn it on and off through out the day, you will end up using more power than just leaving it on.
If you leave the house for work in the morning and return home in the evening, set the timer to turn the unit off when you leave the house and turn back on half an hour before you get home. There is no point leaving the unit running all day if no one is home.
