Coleman Hot Water-On-Demand Portable Water Heater Reviews

We bought this for camping since we do it year-round in all sorts of weather, but it’s been invaluable during natural disasters as well. The Coleman Water Heater kept us provided with hot water during an ice storm that killed power, and four hurricanes. Highly recommend.

We’re dedicated car-campers and have always heated water on the stove for cleaning dishes and ourselves. Never again. The Hot-Water-On-Demand product works very well. You get hot water almost instantly and there is enough temperature control to use this as a shower with the optional sprayer attachment. We still use a sun shower for ourselves due to the hose length, but for cleaning our kids, washing dishes, washing your hands or face, etc this is fantastic. Battery life has been fully acceptable. We charge it before a trip then keep it plugged into the car when we’re moving between camping locations. The propane cylinders last a reasonably long time – we’ve gotten 6 days out of the current cylinder and it hasn’t run out. The unit is light enough to easily move it to where you need it. Ours tends to live at one end of the picnic table and we put a small basin below it to act as a sink. I fully plan to use this for the upcoming tailgate season.

Bosch AE-9.5 PowerStar 1.5 GPM Point-Of-Use Indoor Tankless Electric Water Heater Reviews

My wife reminded me that our children and grandchildren were due to visit our cottage in one week, but not hot water. I placed my order on line and it was delivered in 3 days. Hot water at the cottage in 4 days. Wow it only took me 15 minutes to install. Then hot showers for all on the weekend. Great product.Bosch PowerStar 1.5 GPM Point-Of-Use Indoor Tankless Electric Water Heater #AE9.5

This heater works as advertised! The adjustments for temperature and the 220v hookup should be done by someone comfortable with these tasks – the instructions are not as clear as they could be. The indicator light is very helpful it adjusting the flow as it indicates when the unit is on (there is a click also).

Bosch 2700ES NG Aquastar 7.2 GPM Indoor Tankless Natural Gas Water Heater Reviews

Bosch ES series is a huge step forward in technical development but such a bad taste has been left by former products and Bosch technical support that few plumbers will recommend one regardless of what improvements are made today or tomorrow. This model still has the same potential for gas valve failure that goes back to their 250 SX series that if condensation or rain is not caught before it reaches the gas valve, the valve must be replaced and is nearly 3X the cost of their competitors. Performance is as stated but if your incoming water temperature is not 65 F then expect far less performance. Your homes gas piping and water piping must be taken into account before considering this and the cost of a single wall stainless steel vent system must be calculated into the total cost. Bosch also requires a propritory roof termination kit that if not installed, voids your warranty and this too adds to the total cost.
As a licensed plumber contractor in Ca and a former authorized service provider I had never in all the years of servicing Bosch, seen a correctly installed Bosch tankless. It really doesn’t take that much effort to read the instructions and follow them. Of all the various makes and models we have installed in nearly 30 years, I never once had a failure or problem due to my own installations. Bosch service calls sometimes totaled more than 35 per week on new installations alone by home owners, handymen and plumbers. If properly installed, they are perfectly good water heaters. Tthey do have the best and most robust heat exchangers of all brands, this particular models control board is the most advanced and user friendly of all but only to service providers.
The only downside is the limited access to Bosch technical support too and if not installed to the letter, Bosch may and have voided warranties in the past.
Due diligence goes a long ways and emotional reviews only blur accurate information for those seeking answers. Bosch is making the effort to improve product and service and I will give them that…

Have to amend my first, glowing review. This thing is crap, and Bosch customer service is completely unhelpful. The heater won’t stay on–keeps flickering on and off–and Bosch basically says they can’t/won’t help. We can’t take showers unless we constantly reset the thing. I have spent 1200 for a complete piece of garbage, and I wish I had a 50-gallon heater.
One more thing: if you think you are going to save natural gas with this thing, think again. We have saved ZERO on our gas bill–it is so gas-intensive when it on that is more than consumes what our old one used.
I STRONGLY recommend

ELECTRIC SHOWER HEAD TANKLESS HOT WATER HEATER 110 V Reviews

This unit HAS to have a low flow in order for the heating capacity not to be exceeded by the requirements of the water flow. Water requires alot of energy input to change it’s temp, and the colder it comes out of the ground, the lower the maximum output temp will be at a given flow rate… thus they limit the maximum flow rate so that it will work in places where the water does not come out of the ground at 60+ degrees as it likely does in most of Brazil.
Brazilians may be used to 0.88 gallon per minute showers, but people in the US may be dissappointed, based on what they’re used to.
They should mention this more prominently in the Product Description, which, overall is hard to decipher due to all caps in sections, and a total lack of paragraph separation…
The other thing that should be prominently and correctly identified is that this device, though it is 110 volts, would not be safe to plug into a common 110/120 volt household or commercial grade receptacle. For a safe installation, it requires minimum 10 gauge wiring, and a 30 amp breaker, as 25 amps is not a common breaker size here.
Additionally, wire is not commonly sold with an amperage rating… Wire size is dictated by code according to the breaker amperage, which must match or exceed the amperage requirement of the device… which in this case is 25 amps, so 30 is the next step up in common breaker sizes.
