How many amps circuit do I need to cover 80 sq ft? Is there any reason I can't use this under tile in the shower itself?

Each mat is 15 sq.ft. and uses 3 amps. You would need 6 mats to cover 80 sq.ft. using 80% of the circuit breaker rating you would require a 25 amp breaker. If you can make it work with 75 sq.ft. you would be able to use a common 20 amp breaker.

According to ThermoTile's chart you will draw 12 watts per S.F. and 9.0 Amps for 90 S.F. The same document says it is waterproof and may be installed in shower applications by following proper installation instructions.

Hi; We bought the Tempra 24Plus and are thrilled with it. You'll need 2, 220 or 240 volt 60 amp breakers for the install and you should have it professionally done but we set the water temp to 125 (it goes to 140) and it is more than hot enough. The cheapest place to buy it is Amazon - less then Ebay. Tim -

Wow, I can't imagine that would work. Creating enough current for resistance would most likely be more then the structure would endure. A comercial pool designed for the purpose would cost several 10's of thousands of dollars. I would suggest a cocktail and soaking in peace is a more reasonable plan. However, that said, please post your result. Have an awesome summer, best regards.Mark

The issue is voltage drop and current carrying capacity of the strip, not the power supply (although the power supply obviously needs to be big enough too). You could probably get away with a 20ft run as long as had sufficient current form the supply. I also would plan to only use a supply at 80% of its rated capacity. Most of the low cost ones you see here and other places are not really built to handle 100% duty cycle at their rated output. They'll kill themselves with heat buildup and other issues.

Resistance of the heater, R = (240 V)^2 / 5500 W = 10.47 ohmCurrent draw, I = V/R = (110 V) / (10.47 ohm) = 10.50 ampHeating Power at 110 V, P = (110 V)^2 / (10.47 ohm) = 1155 W, 21% of rated power.Normal wiring will be fine, just make sure its rated above 10.5 amp, 14 AWG or thicker should be sufficient.A standard 15 amp circuit will work, but your water will heat up slowly, 7.6 seconds per gallon per degree FahrenheitAt 240 V your heat up rate would be 1.6 seconds per gallon per degree Fahrenheit

According to the quick installation guide, the maximum amp draw of this unit is 100 amps and not 200 amps as stated on some posts here. How much amp it draws depends on your water usage and temperature. Temperature can be adjusted between 80⁰F - 140⁰F. It does require three 40 amps breakers and that may pose an issue when it comes to older homes. Most older homes main panel is 100 amps with little room for expansion. A 200 amp panel upgrade may very well be worth it.

110 volt plug, but nothing else on that circuit - 20 amp circuit dedicated to the tub only. Also - be warned - this tub does not come with UL listing - I was not able to use it where I intended. Electric inspector would not allow it. Company I bought it from did nothing to help. Said I could send it back - shipping to send it back $450.

The water heater element is rated at 1650 watts and at 120 volts it will draw 13.75 amps. At alower voltage it will draw less because the resistance of the heating element is calabrated at 120 volts which is the standard for all power companies. A 20 amp circuit with 12 (awg) american wire-gauge wire is required. If you plan to connect it to an existing kitchen circuit please turn off all other appliances on that circuit. I recommend a dedicated circuit for this heater. After all this is done it works well for the kitchen sink and dishwasher. Enjoy. Al S. EE

It can draw up to about 1600 watts, so I think a dedicated circuit is in order. Should be GFI protected as well..Here is a link to the manual with the specifications....http://bidetking.com/media/images/User%20manual%20-%20DIB-1500R%20-%20CE.pdf

I have a LED bulb very similar to this in an enclosed fixture above my shower. No problems so far. Because it generates far less heat than an incandescent bulb, I think it's actually safer. Most shower light enclosures are relatively water tight, so this isn't an issue.

This item is sold by the sq. ft. So, you basically need to calculate how many sq. ft. you'll be needing and you can simply order the product accordingly. Please remember that this item comes in boxes of 9 sq. ft. So, you'd need to order the quantity you need in multiples of 9 sq. ft. These tiles can be perfectly used on shower walls and floors (as long as they get installed properly). To finish the job, you'd need to grout and seal the tiles. Please consult all these with a professional installer as each and every project is different and might require special installation supplies. But, you can always reach the seller at 1-877-445-5599 for more information. Thank you. This item is sold by the sq. ft.

Your heater is a pure resistive load plus maybe a small motor and the switch says it will handle a 1 hp motor which is a much more demanding load. As some of the other answers noted, a heater should be fine. 800 watts is well within the range of load they specify. A 1500 watt heater will probably work fine too. Higher than that is asking for trouble (which will be refusal to shut heater off or failure to turn it on after a bunch of uses).If it doesnt work, buy a husky and hug it when you get out of the shower.

it will fit inside of a 2x4 wall -I have 2x6 and had room behind it,in a small bathroom it only needs one of the 2 heating elements to be safe and run it at full amperage I would use a minimum of #12 wire but I useally upgrade to #10, Bx or Romex will work as it is not required to have high temp wiring. I have used it over a year and really like it, not sure about the warranty for what it costs it may not be worth buying a warranty, overall very pleased with it.

My home is 1600 sq ft. I have a 4 Ton a/c, + 4,000 watt condenser running 24/7, plus a 1 horse-1500 watt pump running my pool filter 7 hrs/day running during the summer months, plus two refrigerators, etc. running continuously, and it's enough. I have hot water heat, not electric. My husband said you need to do a load calculation and give more information, i.e, do you have central a/c, is your heat electric? etc., in order to give you an adequate answer. Best regards, Sprity

Great question! My General contractor said "yes" and mentioned he doesn't put a fan in without one as you should run it an hour after a shower. I should have had one put in, it's on my project list of things to do. Any certified electrician can make the connection to the fan side of the unit.

The company recommends incoming water to be less than approx 130deg. I installed one under the kitchen sink, in series with the incoming hot water line. It seems to work fine. I am not sure if it would work for a whole house, it is designed for a single appliance . If you are looking for a whole house, you will need a larger capacity unit, meaning larger power service than a 40amp 220v.

An electrician mounted mine mid-way in a 3'x6' shower alcove. The fan is sealed waterproof unit on a GFIC circuit. Haven't used the shower yet because it's not plumbed yet. The fan is very quiet.
