After some ideas for bathroom heating.

I have an IXL tastic in our current ensuite - useless because it is undersized for the large room with high ceilings. Had one in the past which was great because the room was much smaller.

To bath the kids I take in an oil heater or panel heater (Noirot). Not ideal with water being splashed about.

We are building again and I'd need to work it out pre contract. We are having ducted gas heating so I guess another option would be to put a vent in the bathroom?

I guess the thing about the bathroom and ensuite is that the are both small rooms (2500 ceilings I think) and would need to be heated for max 1hr at a time (for baths) but often less than 20 mins.

what do you think?

Roughly how big are the rooms?

Our minor ensuites are all 2m x 2m - so a small two globe IXL is more then adequate, in fact they are quite tropical!!

Our main ensuite (less separate toilet) is approx 5m by 4m and we have a 4 globe IXL - again more then sufficient. Our ceilings are 2500mm as well.

We are in NSW so not a massively cold area but we find these lamps to be more then sufficient.

Also don't forget your new house may have well insulated walls which can make a massive difference.

I love having a heating vent in bathrooms! Not only does it make the room warm but it also keeps the dry. Can't stand it when the towels don't dry.

Hope that helps

Go and get a raised garden bed that can hold around 1.5 cubic meters. Loop a coil of poly water pipe in the guts on a flat vertical fibro panel. Leave holes and gaps in the panel to allow air and material movement. Chuck the ends of the pipe under your house and loop it again under the floor (if you have floor boards). Then add a pump and 1.5 cubic meters of grass cuttings - keep moist and allow air to get in. The airflow is the temp control.

The water will be 65 degrees for 12 weeks or more.

If u have ducted heating in the bathroom, wouldn't the heat escape out of the exhaust, along with the steam?

No, it's very warm in the bathroom and ensuite with the heating on, I have clients that I shower and lots of them have ducted heating vents in their bathrooms, the heat nearly kills me at times, I can't control how high they have their heaters on. It only cost a couple of hundred to have the vents in the bathrooms, I could have got my DS to do after handover, but I just added it as it was so cheap.

Yep, I agree it does happen. We decided not to have ducted heating vents in the bathrooms for this reason. Especially after a bath, with the fan on the heat is pretty much gone. We are going to add panel heaters to the two bathrooms, there are ones specifically designed for wet areas so they are safe. As they heat slightly differently, rather than just blowing hot hair, I'm hoping the room will retain the heat a bit better with the exhaust fan on. :th:

Sorry for the thread mining, but what about electric underfloor heating? Nothing quite like toasty warm tiles in your bathroom. Could have it set on a timer to preheat before bath/shower times and switch off if you forget.

That's what we are in the process of installing for our new bathrooms; costs about the same a electric towel rails, and our will have programmable timer/thermostat, so we can have it come on with off-peak power to dry the bathrooms and towels. We do have a concrete slab, which should help store some of the heat.

Interested in the thermostats, are they an off the shelf item or do they need to be adapted to suit?

In our case, it comes with the system. We had a choice of a simple thermostat (with on and off) or programmable to have it come on and off at different times, which we opted for to take advantage of off-peak power.

In my experience with electric underfloor heating (2 separate houses, tiled floors) it is not an instant heat but it builds up over time. You'd need to set your timer to start heating a few hours before you wanted to use it. It is not cheap to run.

I'd be using the heat lamps in the lights or a duct (doubles as a drying room so saves on clothes dryer use).

These are not whole house heating, which does take longer to heat up, but the smaller bathroom setup. The whole house system does take a long time to heat up, and unless you a on off-peak, it fets pretty expensive.

These small area systems are rated for 200 to 600W per hour, so would be comparable to 1400W heat lamps, which are used for shorter periods of time, but does not provide drying for the bathroom.

Interesting, didn't know they existed. How are they different through from zoned floor heating? Both houses we had had individual room controllers including each bathroom. Wattage varied depending upon the room size but smaller rooms were around the 500W mark. Still took forever to warm up. Hubby used to get up 2 hours before me, he'd turn on bathroom heater and it wasn't warm when I used it.

The difference in the original ones were they were buried in the slab, and the heating is suppose to last a longer time once the slab heated up (the slab acted like a heat bank). The new ones are just below the tile (on in the screed), so they heat up much faster, but the heat dissipates faster too, so isn't really suited for house heating.

Happy to report the system seems to work well; quite fast heat up, within an hour and keeps the bathroom dry. Pleased with the setup.
