Browse Forums Heating, Cooling & Insulation Re: In-slab heating- -questions 21Sep 20, 2008 7:31 pm Hi Firefox, hydronic heating is a given thing in Europe, either panels on walls or in-slab, and if it heats their houses it will surely heat Australian.
The thing here in AUS is, it's much more expensive to buy and install than ducted heating, it's best done at the building stage (not sure if you can even do in-slab for an existing house). I believe that there's not a lot of knowledge about hydronic heating here in AUS, even sellers/installers seem to have only basic knowledge. I have come across a very interesting article only today (not in English, though) explaining a lot about both panel and in-slab heating (one thing, it is commonly thought in AUS that you cannot have wooden floors with in-slab heating but in Europe it's done, although it needs to be done properly and with the right kind of wood). Re: In-slab heating- -questions 22Sep 20, 2008 10:21 pm i could really only understand the principles behind it if it heated the floor to act as a thermal storage, so i couldn't see it working on a slab with underlay and carpet on top of the slab! tiles wouldn't be too bad though.. i still think its a warm and fuzzy feeling you get when you walk on warmer tiles..
as for the hydronic heating, i guess its like having a radiator in your room. on our ship (cargo/container ship) we have radiators in the mess which heat up from excess boiler water in the engine room, does work rather well... however the temperature is an awful lot hotter! thanks for the insight mek, and yes its strange how the resellers don't know much about there product they are endorsing 2nd-Fix | Blog Building with Desyn Homes previously with the insolvent [url=https://www.facebook.com/7NewsAdelaide/videos/1162546323776021/]Endeavour Homes[/url] Hydronic heating AND Ducted gas?? 23Oct 21, 2008 6:37 pm Hi guys
I'm probably covering old ground here, but does anyone know if it's possible to put hydronic heating pipes beneath tiles on an elevated timber floor?? Our master bedroom will basically be a 'loft'...and we're having a bit of a dilemma about how to heat it. We'd like to use hydronic heating downstairs in the tiled, open plan living areas...however all the bedrooms will be carpeted and as mentioned, the master is upstairs... Is it completely illogical to have TWO systems? Hydronics downstairs and DGH in the bedrooms? Here in Canberra, we can't really get away with having no heating in the bedrooms and if possible, we'd like to avoid using panels or anything visible... Any thoughts would be appreciated! Thanks Adam Re: In-slab heating- -questions 24Oct 21, 2008 8:20 pm Hi Building ACT,
I am probably covering old ground too, but have you seen the hydronic panels they make now that are (relatively) unobtrusive, such as ones that sit as a skirting board, or to go the other way, ones that make a feature of the panels (almost like a statue or something similar)? Just thought I'd mention them just in case you have not seen them - it might be an option for you if you can't do the inground stuff upstairs Re: In-slab heating- -questions 25Oct 21, 2008 8:39 pm Under elevated timber floor.
Possible but not very effective given the inuslating properties of the underlay and carpet and the timber. Better to have a panel somewhere. I have seen in ceiling heating, (electric panels inbetween the gyprock and the insulation, but again, it's not really heating the house from the right spot in IMO. Steve Update on Casa's solution? 26Oct 21, 2008 9:33 pm Hi Casa,
I'm wondering whether you proceeded with your plans and, if so, how well they have worked? Cheers, Angela Casa2 The plan is to use hydronic heating pipes in the slab (PEX- cross linked polyethylene - very robust and last for over 100 years). From there on, everything is different. No gas or electric heater. Instead I'm installing solar panels along the north roof. The more the better. Glass solar panels are about $500 each and "pool" heaters are considerably cheaper. The idea is to run the water through the pipes during winter days (heating) and summer nights (cooling). To enable cooling the glass panels are not efficient since glass blocks heat radiation, which is why the (upmarket) pool heters will probably be best..... I'm aiming for the house to remain between 20 to 26 degrees Celsius all year round without using any air-conditioning or heating. Not sure if I'll succeed, but if I don't I'll be surprised. Re: In-slab heating- -questions 27Oct 21, 2008 9:54 pm I actually only just came across the 'skirting board' option..which might actually be a workable compromise! at least in the downstairs, carpeted areas...still not sure about upstairs...might just have to talk to some Hydronic heating suppliers and see what they suggest!
thanks for the responses Re: In-slab heating- -questions 28Oct 21, 2008 10:00 pm Angela,
I haven't started building yet. The hydronic heating will be there. The solar panels are no longer on the roof, but on the northernmost wall. I should start building in February next year.

If you're thinking of traditional in slab heating, I have heard it tends to be not so useful in OZ because we do not have consistent long cold winters.
