Hi,

I'm in Sydney Australia and looking for the most cost effective method of heating and cooling my house AND providing hot water. With a temperature range of approx 5C ~ 35C it would seem that an ASHP is the best option when taking into consideration unit cost, installlation and running costs. My knowledge is limited but it would seem that there is such a thing as an ASHP that can heat air, and hot water but I'm not sure about cooling air. Can anyone shed some light on this for me? Thanks.
