I'm in the final stages of designing our solar passive home. We are in the Central West so are looking at hydronic heating in slab with maybe a couple of radiators. I have read several articles about a solar system with boosting (ideally for us from heat pump as se are out of town without natural gas connection). We have cold winters so looking at evacuated tubes for the solar. Hoping to design a system that would also satisfy domestic hotwater.
Does anyone know of a designer/supplier in NSW or have any other comments.
