What is the temp rise? Our water temp is normally @ 45? How many fixtures will this support?

Hello Kim,Thank you for your question. You've provided one key piece of information we need to answer the question, the incoming water temp. But we also need to know which hot water points of use that you might use at the same time, and the flow rates of each. Let's assume they are one shower at 1.5 GPM and one sink at 1 GPM. That's a total flow rate of 2.5 GPM. This heater provides a temp increase of 40F at 2.5 GPM. 45F + 40F = 85F. Therefore, the 10L is way too "small" of a tankless heater. We recommend the 16L which gives a 57F temp increase at 2.5 GPM. 45F + 57F = 102F which is slightly hot water for most people.Kind Regards,Ross GadgetsGo Hello Kim,Thank you for your question.

Our temp is also 45, it takes a little longer for it to come up to 180, about 2-3 minutes. We use it in the bar restaurant with no problem, also have one in shower room, just be sure to use free flow head or it will run cold.

Anthony, I'm a bit slow on installing these, I bought 8 fixtures last year and another 2 recently. T8 fixtures are supposed to work well in low temperatures (20 F) so I'm trusting the liturature I read and what I've heard from coworkers enought to buy 10 of these fixtures. Sorry I don't yet have first hand experience.

Depends on the starting water temp. It will come close but that is super hot. Most health departments only require 110-120.

Yes. I have it set at 112 degrees, and there is plenty of hot water. Depending on your shower head flow, you might have to increase your setting to a higher temperature. it s max is 140 degrees.

I own one and I love it! First thing to check is the temperature adjustment knob under the unit is turned fully clockwise. The temperature rise can vary widely based upon that and other things, such as... the incoming water temperature, the flow in GPM (consider the flow all fixtures whixh are being used at the same time if more than one are... the higher the flow rate, the lower the water temperate rise. Also, if yours is a 240VAC unit and your actual voltage is less like 220VAC it won't warm water as much as 240 does. If your faucets, etc. are too far from the heater... some heat can be lost in the run of pipe, especially if it is in a cold area. Note that what causes thermal shutdowns to occur is overtemp, this can happen if the flow is restricted quite a bit, but high enough to activate the heater, and when the incoming water temp is very high. Also never try to connect this type of heater to water the is already preheated. I have some AE9.5 units as well and I know they have the thermal shutdown, I think all Bosch units do.

Our pool is around the same volume. It worked in the winter to about 86 degrees. We had it set higher but it got to 86 and stayed around there. Our pool is outside in the shade with little sunlight. It is deeper than yours but different dimensions. Being inside I am sure you can achieve your desired temp of 85.

I'm guessing that you are starting with really cold water. The heater can only raise the temperature up just so much - 40-50 degrees, I don't remember. The trick is to discharge the heated water into your source bucket which heats it up and pretty quick you'll have water coming out of the discharge end way hotter than you'd want to shower in. Hope this helps.

Charles is correct . . . when you decrease the input (volts) going in you won't get the full rated increase in output (hot water). So if the specs say it will raise two gallons of water say 50 degrees your best case scenario might only be 45 degrees. However, it will still work fine as we installed one in our business that did not have enough juice.

I just bought this and I have a 18 foot round above ground... I raised my temp 10 degrees in about 6 hours at initial start up. yesterday I had it at 82 degrees and turned it off over nite and came home next day from work and temp dropped to 70 degrees and I got it back up in a few hours. I live in Cleveland ohio and keep a solar cove on the pool to conserve the heat...it really matters how many gallons u have. call Hayward the got reallt good techs to answer ur questions,,,this pump was a steal for 1715.00 bucks

It took mine 10 hours to reach 104F after filling it with hose. My water coming from hose was 74F so it went up about 3 degrees per hour. I live on the Gulf of Mexico in Southwest Florida.

From my experience this is not a fixed value. If you set the flow switch at 0.5 GPM and the temperature at max, when you are flowing at a rate just above the 0.5 GPM you can a 90 Deg. F rise per the book. If you increase the flow rate above 0.5 Deg. F the temperature rise will decrease below 90 Deg. F. I have discovered that if I am using only the hot water and decrease the flow rate the temperature goes up. Note: 1 BUT will raise 1 pound of water 1 Deg. F; 1 gal = 8.34 pounds of water. Good luck with your unit, so times getting the proper balance between hot and cold water is a challenge.

Yes, it's very easy to install. Just make sure you have good flow (clean filter). It raises the temp fast but the environment plays a part. We have a 10k gallon pool in northern Ohio. I had the pool open mid April at 82 degrees. I get 7-10 degrees on a sunny day. Lose 1-3 degrees at night.

I have used 3 Tempa 20s to replace other standard water heaters in my apt. complex units. #1, I would not consider a 50 gal water heater as needing a supplement. #2 the Tempra 20 is all you need for a bathroom tub or shower. I am in Wisconsin which is too cold for a 20. and yet they seem to work fine (28s are recommended for this cold climate). You may decide later to forget the 50 gal water heater. Hope this helps. Yes, I would recommend you make this purchase. [If you live in a hard water area, be sure to install a whole house water filter (about $40) ahead of the Tempra or the salts will damage the Tempra flow mechn.]

That's right. The faster the water, the lower the temp gain. I use it for a utility sink in my garage. For occasional hand washing it's greAt, but if you need gobs of hot water, i think you need to go 220v.

I've been running it in a 65 gal marine talk with a 10 gal refugium. I placed in the sump area of the refugium. It worked fine for me in a building that is climate controlled around 74-75 degrees. I found mine to be miscalibrated around 2.5 degrees, though, so you may want to consider an alternate thermometer if you have sensitive stock.

It can go to 140. The temperature rise is the key. Find out what your water supply temperature is on the coldest day and then add manufacturer specs for rise. That will give you how hot your water will be.

I have the 2.5 gallon model under the bathroom sinks. It works very well. The owners manual doesn't show the max temp on the thermostat. The highest setting is not numbered. It says Max. I did find some specifications on line for the 6 gallon which stated the max temp was 140 deg. Jim
