This is just my personal experience and opinion..
I m going to install concealed NORMAL Piping for my renovation. This has been decided after I have asked a few questions to myself and also consulted some friends in the AC industry.
1) Are you installing Inverter ACs? Do you need Inverters?
2) Budget - Inverter piping is more expensive by about RM4-5 /
ft....might end up RM1-2k more ure paying depending on units and distance of piping
3) Inverter ACs maintenance - R410 is more expensive. Cleaning and chemical washing..we're looking at RM200-RM300 or more for 1HP AC
4) WHen is R22 phasing out...my friend told me approx. 10 years ..assuming he is correct...i think 10 yrs...is more than enuff
5) Inverter will only reduce power usage if it's continuously on for maybe about 8 hours or more
-------------------------------------
My Conclusion:
1) Inverter only suitable for my rooms cos I will on more than 8 hours...so for my rooms I m going to use Daikin Inverter that runs on R22 and normal piping
2) The rest are all using normal AC
Hope that helps
Either 8hr use or less, overtime the inverter will payback the cost. Compare non inverter. The cost of the pipe and the aircon won't different alot.
I m using 1.5hp inverter with about 20ft of pipe. The cost + install is RM2200. With everyday usage of 8hr, monthly save is about rm40-45. 1yrs save me rm540. Service 1x peryear is rm100. It take me 2yrs to get back my money save compare non inverter even include service. The amount save is I compare with my last time non inverter unit.
So either 2hr or 8hr use, I still will go for inverter. Payback either long or short. Just my experience.
R410 and R22 gas is depend how enviroment friendly you are. If you care and want to contribute a bit to the enviroment, than change it. It doesn't cost you much. You don't need to top up every year.
