Could I buy two and link them using one as a pre heater to get even hotter water ??

This isn't an answer to the question, but rather a repeat of the question and a response to the previous "answers." Mr/Ms Roby, if you don't understand the question, why did you write an answer? Ms Cowgirl, the Product Description says, "This amazing instant water heater can be connected to the existing hot water piping." So perhaps a better explanation is that YOU cannot hook it up to American piping. If NO ONE could hook it up to American piping, it wouldn't have a 4.4-star rating. Mr Curcie, what difference does it make WHY Ms O'Meara wants it hotter? A shower is not the only way people use hot water. Folks running a food truck, for instance, might need hot water over 100 to make hot tea, instant coffee, wash their utensils, etc. Using the example in the Product Description, tap water coming in at 56 will be heated 45 to 101. This is NOT hot enough for hot drinks, as 101 is only 2.4 above body temperature. Great for baby formula; not great for coffee. If the 101 water from one unit can be run through a second unit, a 45 temperature rise will yield 146 water, which IS hot enough for coffee and hot tea. The biggest problem with Amazon's Q&As is people chiming in with "answers" when they don't really know the answer. So how about it? Does anyone (including the seller) actually know the answer to this question? Or are we supposed to be satisfied with "I don't know," "I don't understand," "I could only guess," and "Why would you want to?"

No. they both heat up on the same control. You could use one side and put water into the other. I wouldn't use one side and leave the other side empty.

I have not done this but it seems as if the thermostat would readily be able to accommodate an adapter to accept 2 devices. Obviously both will be functioning at the pre-set temperature of the thermostat.

Two heaters would make sense if you have a large area and want to space them apart, and if wiring is not a concern for two vs. one heater.

I have this and yes as long as you have the ability to do so externally of the unit. It only has one hook up so I have valves to balance the temp going into it.

You might want to ask plumber about putting both systems in line, but I'm guessing that it's not the best idea. I'mpretty sure the unit won't fire if you've got 180f going in, but you'd also have 180f coming out - which is enough to burn you, regardless what it does to the unit. Personally, I would keep the two systems separate and install some sort of crossover. But I'd talk to a plumbing/heating professional...

Yes, you may. Just move your settings from timer to "on" position. Remenber this is a small pump, you can't have hot water right away.

I would just get 2 of them and you could just switch them back and fourth. It's all up to you, your the buyer but I don't see a problem with just switching it if you leave the switch set at the same heating setting.

Yes just be aware of what else maybe drawing off the circuit you are looking to add the heater to. Requests a dedicated circuit.

Generally, YES. The Tempra 24+ units have a constant temperature output, according to whatever temperature the unit is set for. So, if the incoming tap water is extremely cold, and multiple hot water taps are open inside the house, then the volume of hot water output may be reduced in order to maintain the constant set temperature at all of those open taps. But, the Tempra 24+ has two in-line electric instant boilers and is rated as a sufficient whole house water heater for a 2-bedroom house. So, if nothing other two hot water taps at showers are open at the same time, and the incoming supply is NOT extremely cold, then there should be enough hot water for two showers at the same time. An ordinary tank type water heater could usually start supplying two showers at the same time, but the heated water in the tanks may run out before the showers are completed; that doesn't happen with the Tempra 24+...if you have enough hot water at the beginning with the Tempra 24+ for two (or three) simultaneously open taps, then you will have that same output continuously and indefinitely.

I don't see why not. It is based on ground water temp and flow rate. I live in SWFL and the ground water temp is 65 degrees which gives me a flow rate of 2. I only use it for one outside shower and that has been more than sufficient to have hot water non-stop. It actually might be too strong for your use because you say your water temp is 70 - 140 (very hot). You should consult a professional plumber perhaps about your current system and they may be able to add a solar panel and adjust your water temp - might be cheaper.

I don't believe so. You plug this into the wall and your heat source into the thermostat. I believe there can only be one heat source per thermostat. I know herpostats which are more expensive allow you to hook up multiple sources

No. It can supply one appliance at a time. During cold weather you need to turn down the flow rate for the water to get hot. This works well in a cabin not good for a house.

I'm not sure if two steamers together will give you the right costintancy of steam you might want. If your layering two at a time you might want use a bigger pot underneath both steamers. This steamer is universal from 2 Qaurts up to 4 Quarts.

you would need two of them one for cold and one for hot. plus some adapter fittings to go from the 3/4 nptfemale on the filter to std female and male garden hose ends

That's a lot of water...not sure, it might burn out the element before the water got hot, but probably would keep it from freezing. Maybe having 2-3 would work. Would a hot water heater work better for your needs? Sorry

need more information, Are you wanting to supply two sinks and two showers?These type of water heaters require the use of low flow aerators for the faucet and shower heads or the water will not get very warm. The water heater should also be installed a close to sink or shower (point of use) to get hot water quicker. If you are wanting to service two showers then I would say that this unit is not large enough.
