Tankless Water Heaters

Tankless Water Heater – Has anyone had a good experience?

I searched and found the majority of users are disappointed performance (ESP for low speed) and when they stop working (often), it is difficult or impossible to get any service. The only advice I would to have an expensive Japanese brand (ie, Takagi) and spend the $ $ in the front instead of in the back of repairs and replacements. Certainly there are some users without tank out there that have had positive experiences …?? I have no gas or propane, just electric

See EDIT extremely low power and install these units since years. Yes, very good, and shit. Response to the front, spending money, it's worth. Takagi is good, I install Rinnai also very good. The Japanese have invented and perfected this technology, it makes sense to get a Japanese model. The smart thing to do with the tankless water heater is to find someone who best known for the installation. You can get a list of local plumbers that are certified Rinnai your website, or www.Rinnai.com www.foreverhotwater.com I do not know if Takagi has the same function in place, but problably. This Some of the more technical factors that go into a tankless water heater than any other type of heating / plumbing fixture, it is desirable to have a trained professional to disposal. In some cases, I have not been able to install these units in a house that customers wanted one because it would be cost prohibitive. Then I will discuss some technical aspects, if you are interested in them. To address the specific concerns that you mentioned in your message, some models will not activate (turn on to heat water) without a minimum flow of one-half gallon per minute (.5 GPM, note that the Item 5). It's actually a good thing, because if the unit is activated to begin heating the water, and there is very little water in the heat exchanger (travel small copper box through hot water on the outside by the gas-powered flame), will damage the heat exchanger causing a loss of (very bad). Imagine how a radiator in your car works, lack of coolant, and what happens? Overheating and damage the engine. Another factor that may lead to disappointing results are the type feedwater startup. (/ IE area of the City, or water) with well water, which causes the water pressure (about 40-60 psi). Water for Municipalities may vary considerably, but if too low, say around 25-50 psi (pounds per square inch), the desired output hot water is usually not realized because there is not enough to meet future demand. The pressure may be too high (most codes limit set @ 80 psi), I would say that anything above 100 psi may be detrimental to the unit without tank, pipes and all parties to this matter. Furthermore the amount of pressure, and type size mains water is important. Most homes are sized correctly when building, others not. But if you 60yr old rusted, galvanized steel pipes, youre in trouble, because this junk can go in your wireless network tanks and other equipment and cause problems. Another important factor is the supply of gas, there must be a certain amount pressure gas unit is to feed properly. Some houses are the pounds of gas systems 2 others are half-pound, (natural gas, propane is a little different). But whatever the gas system is, the pipes should be large sufficienttly if this unit is right Gonna Work. For example, if you have an oven (or two) of a fireplace, gas stove, gas oven and a heated pool in the gas, so chances are good as a tankless water heater will starve (or other units) when activated to heat the water. (this can also cause low hot water and damage to the unit) This calculation is made to the diagram, using comsumtion BTU, pipe size, the Committee system and distance to the various units. Even if it is too complicated, is not entirely straightforward. The problem: The problem I see in most cases, the technician (or do-it-yourselfer) installing a tankless system does not properly calculate these factors (if at all). He / she sees a gas, an outlet and two water pipes (usually when the old water heater SAT) and the figures "hey, I'm good to go" and start hookin stuff up. Big mistake. This stuff is not rocket science, but not for the person without any training. As the popularity of these units, so does the demand. The labor force without But evil is totally back in training to keep up with demand, so many systems are properly installed, malfunction of the units are floating out there ruining the good reputation of a really great product. Half of my crew are not familiar with how to install (and So DONT). However, as satisfied users, all my customers were satisfied with their units of hundreds. If installed properly, will do intended to do. But until the initial renovation costs (replacement of tank-type heater) is not cheap. In most cases it is around $ 4000 (review your local auction business field that prices vary considerably depending on location), even avoid hiring someone who does not know how to calculate all these factors and you'll be fine, and Satisified. Hope this helps EDIT VC: electric units are generally not well suited to applications for domestic water heating. Most brands are high for a game or two at a time (like a faucet and shower). There is some without power deposit must meet the demand for whole house, but in my years of experience tend to suck. What we see showers of demand (how many in the home, kitchens, etc.) and compare it with the offer. If an electric heater tankless water can only give it a try Outta 4.5GPM, cuz four and a half liters of hot water for one minute only going to provide two cocks at once. In fact most of the taps is estimated at 2.5 GPMS even (from 2.5 + 2.5 = 5) <- View my better math skills) So if you do not like to wait until your spouse out of the shower before doing the dishes, ID go gas. In many cases, if you have a supply of natural gas in your municipality, the company connects a gas meter at home for free! Its the only way for them to attract new customers on pre-existing homes. The gas is def. way forward. You can also propane.
