We are about to undertake a rather extensive renovation of the bathroom of our 1905 return verandah villa. As the bathroom is over 80 years old, the entire floor is going to be jack hammered up, a wall will be removed also to make the room bigger. We are in the process of chatting to a number of bathroom reno companies and under tile heating has been suggested as a heating option. Does any one out there have any experience of this type of heating?? Any pitfalls? Does anyone know how much it will cost to install per metre?
Love the forum, by the way!

A couple of months ago, I saw an Adelaide company's exhibit at the Home Ideas Ctr (Anzac/South) that can do undertile heating. Can't think of their name, but suggest that you ring them and find out about the cost.

This morning we tried to go and have a look at (or feel of) "Radiant floor heating' in Thebarton, but their showroom was shut!! In fact, it didn't really look like much of a show room. Maybe I"ll try during the week.

We had under tile heating installed over a cement slab in our ensuite, bathroom and toilet by Speedheat. It was expensive (think over $1500), but is worth it - especially when compared to our freezing cold laundry floor!
If you are just doing one bathroom it may only cost $500-$700, depending on the room size and whether you want it to get really warm or just take the chill off. You can get kits and do it yourself, but we had them install it (good move - the electrician hadn't followed our wiring specs so it ended up a bit complicated).
We program our ensuite heating to come on for two hours in the morning, and one hour at night (longer on weekends). It is controlled by the thermostat (which we set around 22C), so switches itself on and off during that time (can hear a slight 'click'). Our other bathroom doesn't get as much use so we just have that set to be on for one hour a day - still keeps the floor 'not cold' but doesn't really heat the room much.
With double glazed windows & good insulation a 0.6 x 6.3m strip is enough to keep our ensuite a comfortable temperature all day (even being on for less than three hours). Our floor tiles are thicker in one room than the other, and this does impact on how much warmth you feel.
I am definitely a fan and would recommend, as long as your expectations are realistic. We moved into the house at the end of summer and when testing thought that the heating didn't do much ... now that the weather is really cold we know just how well it works!!

Should be more specific! This room is 500/13 (total of 540W) which is 130W/m2, you can also get 200W/m2.

Am in the planning stages of building and am interested about underfloor tile heating in the bathrooms.
Just wondering if you are finding it expensive to run?
We haven't got our first non-building power bill yet ... which is actually starting to worry me a little as it has been almost six months. Checked the meter and since the power was connected at construction 12 months ago it is up around 2500kWH ... I think (these new fangled meters are way too complicated!). Probably not too bad considering we don't have natural gas, everything is electric, and one of us has been home every day for the three coldest months of the year!
Our undertile heating system is less than 1kW for the three rooms. So, if we had it set to come on for an average of four hours a day then our total cost would be around 56 cents a day (assuming that electricity is around 14c/kWH and the system was on for the entire four hours - which it wouldn't, switches off when it hits the programmed temperature). Also remember that you would switch it off entirely during warmer months.
If your house is not well insulated and you want the undertile heating to warm a large room 24 hours a day then I could imaging the running costs getting quite high. If you mainly want to heat the floor and have that blissfully warm bathmat on a 4 degree morning then it shouldn't cost very much at all!

We also have undertile heating for the bathrooms and tiled living area/kitchen. Unfortunately for me, I'm not allowed to turn on the bathroom heating on a normal basis . It's been deemed by "the electricity nazi" a waste of money since the only time spent in there in the morning is the 5 minutes brushing the teeth.
The larger living space also hardly gets used, but the times it has, it's been great. You can really feel the difference when you step onto the unheated tiles. The reason why it's hardly used is that we do not spend a great deal of time in those rooms. Typically we cook dinner, then retreat upstairs to the carpeted living.
So given that our system gets hardly used, do I think it was a waste of money having it installed? No, purely because it's too costly to install it afterwards and it's our lifestyle that is making it impractical to use it more regularly.

Thanks everyone. I've certainly been given lots of food for thought. One of the reasons we were considering the under floor heating is that we are designing a federaton bathroom and thought that a heat source like that would not interfere with the olde world style. However, we've decided to go with a Tastic instead, simply because I like the radiant heat and because we spend so little time in the bathroom that I find it hard to justify the electricity the underfloor heating would use just to heat it up for us to be in there for 10 mins! Also,-I'm a bit of a sook and like instant heat!

Hmmm... having used bathrooms with floor heating and bathrooms with Tastics ... would go the floor heating every time (but I am a REALLY big sook!). For some reason I always feel that the Tastic is burning the top of my head while the rest of me is still cold. The floor heating is a much nicer heat, but you are probably right from an energy efficiency point of view.

Sorry to butt in here! I am in the process of a house overhaul and we are getting underfloor heating for sure!
A friend in Tassie has underfloor heating under their carpeted living areas while they have Tastics in the bathrooms. No comparison. The radiant heat from the underfloor is truly delightful while the Tastic scorches your noggin and blinds you in the process.
FWIW when we were there the temp was hovering around 9C and the thermo was set on 22C; bliss! I think I was perspiring

My name is Luke Chant and my company is Hotwire Heating. I believe ours is the display at the home ideas centre that was referred to in an earlier post.
All the information I have read here so far seems to be correct. Under floor heating particularly in a bathroom is amazing. It is so much better than an IXL. An average bathroom can be fully installed for around $700.
If anyone wants any more info you can contact our office 08 8440 2422.
Thanks and sorry to get a bit salesy in my response.
