We are building a two storey house in Melbourne and have been looking at hydronic heating. The two basic approaches we have been given are 1. all radiators and 2. slab ground floor and radiators upper floor. The cost difference is negligible (all radiators slightly cheaper).
We have been leaning towards option 2 mainly because we don't know where to put the radiators on the ground floor especially (lots of windows going almost to floor) and to be honest we don't really like the look of the standard radiators . We also like the idea of a warm floor (we usually don't wear shoes indoors). On the other hand we are worried about the long latency of slab - particularly given Melbourne's changeable weather esp in Autumn and Spring. We will have a gas log fire on the ground floor and had hoped that might tide us over as the on demand heater during spring and autumn.
I would appreciate the opinions and especially the experiences of people who have put in hydronic heating in Melbourne. Have they regretted putting in slab and how do they handle spring and autumn. Do they find themselves getting too hot and having to open doors and windows. If they did put in radiators have they gotten used to them or found some way to minimise the visual impact. Has anyone used any of the designer radiators, many of which appear to be aluminium.
