How hot will water get on a constant circulation? I want to use to keep a spa hot/warm as a circulating system.

Hello, The maximum equilibrium temperature depends on the total panel area (number of panels) and the quality of the insulation in the system. For standard spas of about 300 gallons most customers use 6 to 8 panels. If your spa is smaller and/or very well insulated you can use fewer. Thank You, Heliatos Solar

I don't have experience with doing that, but this machine does have a limit to how hot the water can be that you put in it. How hot are you looking to go? If the water is too hot for you to touch/ work with, it is too hot for this machine. I generally go by the rule of "if I would shower in this temperature, then we are okay, anything hotter is pushing it". Its made out of plastic, and the parts can melt if you go to, say, boiling.

this unit gets very hot but it will kick off a 30 amp breaker if you leave it running for more than 10 minutes. it is intended hand washing and fast hot water in short terms. great for a bar or small sink, bathroom sink. i think you need a 6 gallon water heater for a tub. this unit does heat the water by 40 % of what the ambient water is.

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

If you're getting 116F you are an extremely lucky individual. Mine might reach 100 on a warm day. I don't really undersand your question, but if you increase the flow of water throught the device, your effective temperature will be reduced.

I had the same concern, it has a thermostat so it only runs when the water temperature is very cold. It also doesn't feel hot even when running. Trust me it will do a great job.

Dan, this would heat up any size pool. Our is moderate in size pool with spa. A small pool would heat up very quickly, and larger pool would take more time. You are putting ~ 250,000 btu/hr into the water, which is like 2.5 furnaces for a good size home up north. Once you get the pool or spa up to temperature, and it drops below setpoint, the heater will run briefly for a small pool, and a lot longer for a large one. THey'll pretty much keep any size pool heated, just depends on how long it has to run to heat it up initially, and then run time to keep it there. Hope this helps.

I usually start with hot water, but the thing will heat water and keep it at a nice temp. I like it hot, not tepid, and it does the trick.

Not sure but mine has extremely fast flow for both hot and cold for a large spa tub.

None...no real heat produced...you have to keep adding warm water to it....cools off right away

My water stays cold or room temp. Never ever warm. You may want to call about that.

Each "pass" through the heater element (where the flames are) raises the temperature by a certain amount, I would guess about 40 degrees. So if you put water in that is, say, 50 degrees, it will come out at 90 which is a little cool for a shower but not uncomfortable. If you run the water back into the container you originally pumped it out of, it will get up around 130 degrees, which is too hot for shower but OK for dishes. However, it's a gradual process and depends how much water you have in the original basin. What I do is to run it until it is comfortable and then turn off the flame but leave the pump running. I would probably not start with warm or hot water from a tap, just like I wouldn't cook with such water, because by sitting in the pipes or hot water heater it has dissolved sediments and chemicals in it. The colder the water, the less sediment/chemicals in it (except for gases like oxygen). So to the extent that you want to avoid getting corrosion build-up in the heater element it would be best to start with a colder water. However, there is no problem running water of a warm temperature through the heater element, per se, though eventually it could get so hot it might melt the plastic tubing or something like that. By then it would be so hot you couldn't even touch it. Just pay attention and you'll get it just the right temperature.

This unit produces a mildly warm water source from a cold water source. The water is not hot and will slow down your flow.

I usually do foot spa for about 10 minutes. And for that time period, the water was kept at an comfortable temperature. I am not completely sure about if time going beyond that. Hope it helps.

The water will have a natural circulation due to the warmer and cooler water moving around each other. Larger items will reduce this circulation. I use a aquarium pump with a air bubbler to help move water around. There are high temp mini water circulators available also. IMHO the water circulation is only needed when there are large items that inhibit the natural water movement but a simple bubbler will take care of that.

I have run two showers at one, there is no change in the temp of the water, just the pressure. You can run the tap for hot and it does not rob the hot water from the shower, Temperature is maintained no matter what. My only problem is trying to get my 13 year old daughter to decrease her time in the shower from 30 min down to 15, Never runs out of hot water.

Hot water is only produced when there is demand for it and there is a short delay while the water is heated. So, you can get a momentary cool water output, but I would not call it a problem. In fact, I hardly notice if it happens.
