Thank you for taking time answering my question! What did you eventually opt for? Our tender comes with 14k premium daikin ducted with 16.5kw rated heating capacity. Original heat load as computed by aircon technician is 19kw based on day time living areas. So he recommended either 16kw or 18kw. We upgradee our insulation level and window glazing. We also made windows smaller on east and west and bigger on north where the living area faces. Our climate zone is 65 which is cool temperate. After the uograde builder provided me Nathers report with 161.5 MJ/square meter-year heating load. My daytime living area is 105 sq meters. Convert all MJ to Kw. Resulting to around 12.90kw this we didn’t upgrade and just happy with 14kw. Moreover, builder quoted $5900 for 16kw upgrade and $8000 for 18kw. Too expensive. I said to myself the upgrade price can buy another brand new unit. Just save the money and spend it when in the future when the old one fails. I think the smaller unit is cheaper to run based on our use. While glazing upgrade for windows a bit dear. And insulation isn’t significant, I think they are better options for me. That's good outcome. May I ask how did you convert the MJ/Sq into KW to get the 12.90kw rating. I am also trying to find out mine so just wondering if you can please help. Just trying to size the approximate kW rating for AC. Re: Which ducted aircon size? Daikin 16kW or 18kW? 16Sep 15, 2021 7:13 pm Leona33 Ceddy_83 Leona33 Wow!
