I know this is an old post, but im deciding whether or not to use slab insulation for a home with hydronic heating in Melbourne. Are you suggesting that a waffle pod slab will do part of the job? is it worth 10K to also do slab insulation? Thanks in advance! Re: Tips on maximising energy efficiency in Canberra 6Jan 11, 2023 7:49 am Hi there. Slab insulation is a MUST with in floor heating to achieve the best results. Waffle pods help but its not a part of the solution for in-floor heating. Not using slab insulation with in-floor heating is like having triple glazed windows without wall insulation.

Re: Tips on maximising energy efficiency in Canberra 7Jan 11, 2023 9:41 pm I know someone in the Adelaide Hills (similar to Melb climate) who only has waffle pods and no slab edge insulation. Their hydronic still works well, but I'm sure it would be more efficient with slab edge insulation and perhaps better under slab insulation. How much more efficient I don't know. Might not be worth the extra cost. I think in Melbourne it's recommended to get slab edge insulation anyway regardless off having hydronic. I'm not that pro hydronic anyway. It's pretty laggy so you don't get a quick injection of heat/coolth when you need it. It also uses a lot more power (than RCAC) so if you need to use it out of solar hours it costs more (or uses a lot of battery energy). It's a luxury imo so if you have the money then go for it. go upvc window frames ensure insulation under colorbond. not just sarking, lighter color roof also not sure if you have seen this viewtopic.php?t=5823 last couple of pages… 4 111150 Wow I hadn't realised things had gotten that pricey in just a couple of years since I built, that is crazy with how much land is now costing if you aren't lucky enough to… 3 7269 |
