TITAN SCR2 N120 Electric Tankless Water Heater Review

Nice product and once I worked out the wiring and circuit breaker needs it seems to work very well. I hooked it up to the current hoy water heater wiring and fuse only to find it needs a 60 amp fuse and 6 gage wiring from fuse block to heater..This was not too expensive because my heater is only a few feet from the fuse box the wire is $2 per foot and a new fuse was $8 so it added $50 to my bill and an hour running the wire through the crawl space. It does appear to work as promised, nice hot water instantly after connected.

NO TANK - SPACE SAVERNO LIMITNO WAITINGSAVE UP TO 60% ON WATER HEATING COSTS!One way to SAVE on domestic hot water bills is to use A DEMAND TYPE WATER HEATER. A conventional hot water system heats water in a tank to a specified temperature. As heat is lost from the tank, the water is reheated until it reaches the specified temperature again. For most of the day the water in the tank is not used, but it loses heat continually. DEMAND WATER HEATERS Eliminate this problem by heating water only as hot water is drawn. Facts: The average tank hot water Heater will supply only enough hot water for one or two showers before running out of hot water! Not with Titan Electronic Tankless Water Heater! IT IS EASY TO SEE WHY CONVENTIONAL WATER HEATERS ARE NO LONGER ECONOMICAL OR PRACTICAL... They consume electricity to heat water that is not being used, a process that repeats itself over and over even though no hot water is needed. The "TITAN Electronic Instant Water Heater" provides hot water ONLY when you need it, without the costly reheating process. An electronic component monitors the temperature of the water at different flow rates and maintains a pre-set temperature, allowing the use of conventional or single handle faucets.Professional Installation is highly recommended.

Factory-Reconditioned PowerStar AE125-RE Whole House Electric Tankless Water Heater Review

We bought this water heater for our guest house. After major rewiring and plumbing changes and drywall repair from the rewiring and plumbing, we were finally ready to install. The installation went well and at first it seemed the system was working. However, after a short period of time, the water was not staying hot. It fluctuated in temperature when taking a shower and trying to do dishes in the kitchen sink, it actually went cold. We thought something was wrong so we called CPO (where we bought it) to see about getting this unit replaced, and they referred us to Bosch. After troubleshooting with Bosch on the phone, changing settings, water flow, etc., over a period of a few hours, we were not getting the improvement we had hoped for. To get hot water, the water pressure had to be turned so low that you could not reasonably expect to take a bath...it took forever to fill the tub. We continued to try different settings for a couple of days, but we had guests coming and needed hot water (which we had tried to explain to Bosch) so we went to the big orange store and bought an identical unit for $649. That one worked much better and proved to us that something was wrong with the first unit. Trying to return the unit to CPO, they required an incident number from Bosch. Called Bosch to get an incident number (why didn't we get one in the first place?) and had to call back several times due to long waits on the phone. They will not give an incident number unless they determine the unit is defective. If the board needs to be replaced, they will replace that, but will not give us an incident number to return the unit. So now we have a paper weight that cost $400. CPO will take it back, but not without charging a restocking fee and shipping. Why would we want them to restock this and sell it to someone else? Our only recourse at this time is to get back on the phone with Bosch and try to have them determine whether or not this item is defective. Never mind that they would have us go without hot water the whole time. This has been frustrating and expensive. Also, even though we have one that works, it is not really robust enough for a whole house water heater. Better as a point of service heater, but then you better make sure you have a big enough electrical service in your house to manage everything else you need to use. We have 200 amps, but if we needed two of these units, we'd have to upgrade our service in order to accommodate the huge amount of power these things need up front. Don't buy one of these unless they get the technology more stable.

Bosch AE115 PowerStar 2.6 GPM Indoor Whole House Electric Tankless Water Heater Review

I have used these units in several buildings. The biggest building being an 8 unit building all with 1 bedroom apartments. Each apartment has it own hot water heater.
We have OVER a 60% fail rate. First you do a LOT of electrical work to get to the point of being able to install it. Then you put it in and this what progresses:
- day one works great and you think "what a great idea I had"...
- few weeks or months later it is hot for a minute, then warm, then cold as it runs
- you reset the unit try and test everything, it works ok you think
- get a call a day later it is the same warm then cold then warm showers
- you take it out and return it to the store.
I have replaced 3 yes THREE in one single apartment alone. All in all I bought 8, for an 8 unit building, and have installed either new or replacements 18, in a eight unit building that only has 8 on any given day, at this time. I am a whiz at getting them in and out.
So if you are looking to waste money and a LOT of time as you replace it and try and fix it etc this is for you. These could not even sustain a 1 bedroom with ONE tenant. All my units have a single tenant in them....
I did call the company and they are very nice. The guy I was talking with was a technician on what they called the "pro side" for builders professional etc. I explained everything to him and told him of my fail rate and he said that was possible. So they know of the problem, over 60% fail rate did NOT even phase him, he obviously had heard about this plenty of times before me......

Bosch AE125 PowerStar 4 GPM Indoor Electric Tankless Water Heater, White Review

I purchased the Bosch AE125 Electric Tankless Water Heater 4 months ago and have regretted it. Several considerations should be taken.
First the unit is not an analogue to a conventional tank-type water heater. It delivers hot water based upon a system that measures the incoming water temperature and flow rate and then "calculates" the number of elements (it actually has 6) that it turns on to provide an outflow temperature based on the setting of the temperature control. This system is not satisfactory for a water supply which varies in pressure, SUCH AS A WELL, as the unit itself provides substantial resistance to flow and thus the flow rate through the unit varies and thus the temperature of the outgoing water. This causes the delivered water to vary widely in temperature, from VERY HOT to VERY COLD. The unit would be improved if it was "smart enough" to not only measure incoming temp, but, also, outgoing temperature and flow rate and maintain the outgoing temp at a constant level.
Second: The unit has a flow sensor, which will shut the heaters off at low flow, so, therefore, if you wish to have a small amount of hot water flowing into your sink for shaving purposes, the water will not be heated at all. This "Feature" also has considerable influence on the use of "low flow" faucets.
Third: If you have a home which is heated by electricity and you install this unit, be aware that it consumes 120 AMPS at maximum heat rate. In my case, my electric heat consumes 120 Amps, also; my home has a 200AMP panel. Do the math, turn on the heat to warm the house and then take a bath, and suddenly the entire house is plunged into darkness. I have decided that I must sense when the water heater is turned on and prevent the central heat from coming on. This should be doable, and since the unit only runs when hot water is required, should disable the central heat only for short periods. HOWEVER, this is a feature that should be provided by Bosch and/or their literature should make clear to the potential purchaser that this is a problem with the electric heater.
Fourth: The unit apparently switches one or more of its six elements on or off as it attempts to heat the water. There does not appear to be any partially on for any of the elements. This leads to the problem of "stepped" heating of the water. And because the unit measures flow in and calculates the outgoing rate, if the water is mildly too hot or too cold, simply changing the mix at the faucet does not necessarily result in mild changes in temperature, a tiny change at the faucet can cause one or all of the elements to switch off resulting in a dramatic change at the faucet. AGAIN an argument for sensing the outgoing temperature and maintaining it by modulating the elements for a smoother temperature curve.
I would rate this unit as unsatisfactory for any home with a well, and only marginally acceptable for any home with electric heat (but only if modified as I indicated above).
Had I known then, what I know now, I would have saved myself a lot of money and frustration by purchasing a conventional tank-type water heater.
