I have this tank less water heater and I am NOT very satisfied. It does its job, but it takes forever for a bathroom shower to get warm and is very inconsistent.

You need to check with the manufacturer for the model they recommend for the number of bathrooms (bedrooms don't matter). The Tempra 36 works great for our 2 1/2 bathroom house.

There are charts to look at. My read says a size 2 at 1.3 gal per min will give 1500 psi. Look for yourself. The 3 will work but give a lower pressure.

No you need a special type of heat element for that this one you ask about is for the type that hold water to heat. You can find out what you need for the tankless water heater by entering the model of your tankless water heater.

I agree with Gordon Levin. Look at Stiebel's Eltron sizing chart. Your electrical service, and your seasons have a huge bearing on the unit you choose. I have had the Tempra 2 Plus for 6 mos running the laundry room, 2 children's bathrooms and the kitchen without any problems in Houston.

Any tank will work because they are connected by a pipe fitting, but the larger the capacity tanks will save on electricity and your pump will last longer because the pump runs less. Replacing my small tank with this larger one dropped my electric bill more than $12 a month.

According to Eheim, the following heaters should be appropriate:Model 3616 150W heater: 53-79 gallons (US)Model 3617 200W heater: 79-106 gallons (US)If your tank is in a room that gets very cold in the winter, you might want to go with the 200W heater.

Tankless water heaters will handle almost anything, but the trick is sequencing / timing. If all three teenagers are going to take baths or showers at one time, it may not provide enough hot water. To some extent this will depend on the size and length of your water lines. I bought one of the to heat my hot tub and two larger, 9.5 gpm units; one for domestic hot water and the other for radiant floor heat. They all work great. The price does seem to vary so keep an eye on the prices over time. The PVC vent system is much better and extremely lower in cost than those tankless water heaters that require stainless steel vent pipes. Good luck.

Two choices. Either two 100 w heaters at opposite sides of the tank or a 200w should work. These heaters are powerful and heat better than other brands of the same wattage.

I originally ordered the wrong model and it was really easy to return and get the correct model. It was a few months ago so I can't tell you exactly how it went but I don't have any complaints about the process. Additionally, the tankless water heater is kick butt! My bill went down 10 bucks a month and I have a ton of room in the closet on my balcony now. The extra space is so worth it!

After considerable research, 15 mos ago I purchased the Rheem 81VP2S, 2 1/2 gal system. We placed it under the kitchen sink because we could only get warm water. My wife has been very happy with it. The unit provides instant "HOT" water and I believe this size would be sufficient.

Hot water should work fine, but it is too small to heat an entire house (maybe a single room)

I would go with at least the 50 watt. Probably the 100 would be better. You can always put it a little bit diagonally in the tank. it is ok to fully submerge even the top part. I would consider going with 2 50watt heaters with one on either end of the tank for a more even heating effect. Plus both heaters would last longer because neither one would have to work as hard.
