HI,
We have bought a 20 years old house in Sydney. It has two installed split system AC. The AC do warm the rooms quickly, but we would like hot air in more rooms.
Options
1) Ducted AC :: Too expensive. Also, we already have 2 split AC, so better to install split in other rooms.
2) Split system AC :: Seems the most sensible and the cost effective way or running.
3) Oil heaters :: Use them for the time being, till we get a good deal on Split system .
What do you guys recommend ?
What is the Return on investment of Split system vs Oil Heaters ? Worth to just rush in with split system now ?
Oil heaters will cost 5 times as much to run for the same amount of heat.
Reverse cycle AC is the least expensive heating.
