Has anyone used this in Northern climates (Northern Canada...)? I've heard that tankless can freeze &amp; burst pipes from cold air coming down the vent.

It does have an internal freeze protection circuit to keep things warm inside. The folks at Rinnai Customer Service are very helpful. They may be able to address arctic conditions.

Sorry for the late response on this! Yes, definitely it works great. I have a 3 bath house that has pressure set to about 80psi, and two showers can run at the same time, but it's about the same as when we had a tank (i.e. if it's winter you have two unhappy showerers.) But overall I'm stoked with the performance and propane savings over our old tank, which I will admit was pretty old (10+ years.) We'd never serviced the tank and I'm sure it was getting pretty well filled up with hard water deposit. I installed it myself, and going in cold with just a few youtube DIY videos under my belt I was able to patch in a few feet of black pipe and connect the unit with flex line, and also cut the ceiling and roof for the exhaust (about 7 feet of vertical run.) Hot water response is a few seconds slower than with the tank, so in our back master bath it takes about 20 seconds for the hot to arrive instead of about 16 seconds as before (YMMV based on distances.) Good luck either way you go.

I am no pro but I am a "handy" female and I installed one this weekend. Mounting was so easy it should not be a worry and The outside Tankless heater does not need venting so that was a big plus for me. There are Three things you must check you have before you start: #1 Must have 3/4 inch gas line (check for your model) for this model. I upgraded mine by replacing the T at the main pipe (Tankless needs the capacity so no cheating by using a reducer to size up from smaller capacity). #2 Must Get the Tankless Water Heater Service Valve Kit or you will not be able to service/clean it and save yourself heartache (it will break easier than standard HW heaters if not serviced regularly) I got mine at HD. #3 Needs 110 v electricity (I put in a light switch outside and put outside cover over it so we could turn it on/off as needed). One thing everyone should be aware of that can be a gotcha: There is a sensor which will not allow the unit start until all gas/water/electricity are hooked up and if you do try to start it before then (such as when trying to test the electricity to the thermostat like me), their is a sensor that will not allow it to start until everything is hooked up. The thermostat may not come on after doing this. It needed to be reset by turning the electricity to it on and off; I just used the GFI on the outlet on this electrical run to turn the electricity off and then back on to do a easy disconnection/reconnection of the electricity to thermostat which did the trick. The thermostat came back to life and it worked. Now my tenant is enjoying hot water. This guys installation videos were excellent and where I learned about the valves! http://www.youtube.com/watch?v=LKhXoaRg6k4 Hope this helps. I will be getting mine inspected by the city as part of an existing permit for a remodel. Let you know if anything comes up after that, but it should not.

must be a pressure demand. I use mine on a 5 or 7gal tank and it works fine. I have noticed that it automatically cuts off after about 1/2 hour. I like that but didn't see anything stating that this is supposed to happen. I have been pleased with the heater.

Two ways. First, the unit has a small breaker switch that pops if it gets too cold. Second, the unit is available with a cold weather kit that will keep it from cracking. The one I ordered here had this kit pre-installed. It's a great unit. I highly recommend it. Best thing I ever did for the RV.

I bought the Tempra 24 Plus about 8 months ago. I have a 2 bed 2 bath house in Florida. My pipes are fairly exposed to the temp swings as they are all run under my house in a crawl space. Take into account where you live. It has provided more than enough hot water for a family of 2's needs in my use case. We occasionally run 2 showers at once. I notice a small dip in temp when we do so, but it is easily remedied by backing off the cold a tad. I am very happy with my purchase.

Hmm. Aren't you supposed to put a fanless convection heater in front of the coldest area. A sliding door should be ideal. That's how the heat spreads around because of the differential in temps. That's the point of getting a fanless convection, I thought.

Yes, I am having a great success with this unit, it has been extremely cold winter, it has keep my pipes from freezing. Very easy to install

Hi, I can't say for sure as I have she Noritz, but I have a water softener. I do know there are many recommendations that if you have hard water something should be done to prevent build up.I assume you're considering a tankless as a move away from a tank style water heater. If your tank style did not last many years I'd suggest something to protect the tankless. This of this. These units run water through small tubes that are heated to make hot water. These tubes wouldn't take much to be come clogged. Hope I was of some help.

how long does the temp stay that cold. If you are just trying to keep the tank from freezing up I would say yes. With temps reaching that low from time to time I would put another heater in there around fall time. So one heater does not have to work all the time. I hope this helps

I used mine for about a month (2nd home) before I shut it off for the colder temperatures.I have to say - IT WORKED GREAT.

I have not experienced this model in the winter since it was purchased in the warmer months but I imagine with the outer insulation around the tubing it should not freeze up as fast as the previous model I still own. The previous model with the insulation around the tubing would freeze up in the winter months. I kept it in my car at all times as a water source.

HelloThe unit you are inquiring about is an INDOOR unit - but in case you leave the house unattended, and it might be exposed to temperatures below freezing: You should inquire with the manufacturer, Tagaki Toll Free: 888.882.5244My hunch is that if the house is unattended during freeze temperatures, the pipes would have an issue as well. Please call the manufacturer and be consulted for what is best in your specific situation. Regards, Buy and Large Inc

I fellowed the directions and POR-15 worked great, My gas tank on my snow blower had a 1 inch long crack plus a couple of pin holes. The blower was stored out in shad all winter long, this season was long with 50 days of below zero.

I live in Southern Texas so have really never had any trouble with it freezing. I just have foam and duck tape around the pipe it is attached to.

The only problem I have had is if the heater is outside the water in it can freeze and ruin it, but if only the propane tank in in the cold it probably won't matter. But no way keep the heater with water in the tubes out in the freezing temperature. It does not hold water in a tank but it has tubes that are exposed to the heat as it works...they when full of water can not be exposed to freezes. As far as my experience. I have gone through 3 of them outside. Otherwise they work great.

We use this valve with a tankless hot water heater - works great. If it gets too hot, we turn the handle towards the cold setting. I hope this helps to answer your question.
