Use Heat Exchange

Use heat exchanger, in order to save hot water can save a lot of heat energy, but also to open up or close tankless tankless, electric, or you can not have the possibility of a tinyhouse hot water system, because they need too much power. This reduces tank standby losses, but also save quite a bit more energy overall. These findings Google search for "heat exchanger shower. " There may be more. In any case, they are, I think, counter-current heat exchanger. Thing is, these ecodrain page map is not the best way to use a heat exchanger. Not at all. The optimal configuration shown in Figure 1. Sorry, this is a little messed up. Click to view the original. In short, you want to do is to heat, drain lines, but before that, no, the hot water tank. Heat exchangers, such as "powerpipe" With this configuration, they are connected to the sewage outfall. The problem is that they are designed to let water through, which makes the heat transfer efficiency is very low. However, if you are starting from scratch to build a tinyhouse, it is not difficult, so now only need to deal with the heat exchanger separate gray water, sewage drain line, you can use one of the ecodrain equipment. Does not have cold water line. Only a cold line. All incoming water must flow through the heat exchanger for maximum efficiency. Another method, which is to control the output power, rather than mixing with water, the water heater temperature control knob to direct the use of electronic control knob. Later on. Now, how will this change things? Well, let us just want to heat, eventually 85% efficiency. It may easily be more than that. If there is a 1.5 GPM (~ 6 liters per minute) shower head (faucet can use the system, but in the water and heat demand, shower the worst case we focus on), and water is a typical 6 degrees Celsius, and you want to water is a comfortable 45 degrees Celsius. You will need about 15.6 kilowatts heating power, if you do not use heat exchangers. So, you now have 15.6 kilowatts of heat will be wasted. Heat exchanger back 4 * 0.85, so you only need to provide 4 * 0.15, or only 2.3 kilowatts. This is a 30 amp circuit on the 120V heater is feasible, but it may be better to improve heat transfer efficiency. I bet they probably than good, anyway, quite a bit. It also makes use of solar water heaters is much easier, because your collector is a lot smaller. Now, but how over time, when you turn on the tap of the temperature change, when you try to adjust the temperature requirements? You can see that it does not act the same as a traditional system. You do is control is added to the system, rather than a temporary amount of energy. Output in the shower. As the temperature increases, the amount of increased heat loss through the heat exchanger, and eventually joined the practice of the amount and the amount lost a balance. With a tankless system completely, but also when it starts heating system problems. The heated water supply and sewer pipes, standing demand. Suppose you have a 2.3 kilowatts heater. Only estimates how long, because the water is running, 15% of the heat into the lost, so it's effective to use 1.95 kilowatts of heating water supply and sewers. Assuming there may be 4 m, diameter 1.5 cm, about 700 ml of water supply lines in the supply line. Let's assume it's the same drain line. Water lines are in the room, so let us assume that it is 21 degrees Celsius. 1.4 liter, needs to be heated to 45 degree angle, will use 1.95 kilowatts 67 seconds. HM. But the pipe line can be shorter than in a tinyhouse lot. You can use a more narrow line, too. Too long, really, but, unless you gather things, the purpose of heat nearby. In order to reduce water waste, reduce the time a bit, you can put directly on the supply side of the heater heat exchanger output, open the appropriate amount of water, the water from the water heater is the right temperature. Because the water is heated by heat exchanger before, even once, you will get a full 2.3 kW. In addition, you may want to know how to reduce the temperature, if you have hot water, a sudden want to switch to cold? So, you need to remove the water from flowing through the system energy. You can turn off the heater and let it escape through the heat exchanger. Especially if the heat transfer efficiency, in fact, it may take a long time. Another method is to have a leading leading the way it skips heat exchanger, fully-inch water line of the third, if we use water as a power cord, and then discharged through the heat exchanger, which refresh the hot water that is in the system, lost all energy. Heat exchanger has no effect, because there is no water, outgoing water through the heat exchanger to heat up. You can then again so much energy back, when you want hot water again. But the whole system will still consume more energy than a normal system a lot less. Law of diminishing returns applies here, so this may not be worth the complexity and cost, but another way is to try to store energy. You can use the switch and the required heat storage. Or you could just use a small water tank. This is probably not using I mentioned the third line of the water. Just think, which is located between the shower drain and heat exchangers. Water can flow, a layer in the way, first in first out, that there is no hot and cold water mix. Can be coiled tube for example, "tank. " It not only has storage above 1.4 liters. Water does not flow normally. It is usually filled with water, at room temperature, or it may be located outside of this water is maintained at the temperature of the outside world, or it may be a water heater tank, allowing it to be used for system startup, too. Switch to the system simply, just long enough to replace the cold water and hot water system, it is only stored hot water, until you want it back. At this point, hot water, cold water displaced, the majority of calories you have your back. If the entire system is computer controlled to take care of everything, so you just tell it what you want...a temporary computer can be used to control other tinyhouse system, so it is not too expensive. One thing: I did not check things like these ecodrain price, but you can put your own heat exchanger is only the plastic tube stainless steel tube, . The heat exchanger may have accumulated on the surface of things, but since you are not anti-stick coating (unless, maybe you can get some anti-stick coating tube). Another problem is the leakage resistance of the water line. These ecodrains are designed with the drain line flow than in tube heat exchanger tube's resistance is much lower. However, if you use the drainage pump, will overcome, you may need a drainage pump, anyway, because few in tinyhouse gravity down. Google Product Display <$ 100 pump, the price may not be prohibitive. Source: dawn-hz.com
