Bosch Hot Water Heater - Aquastar 1600H review

Advantages

Bosch Aquastar 1600H model is the best Bosch water heater as cheap or budget friendly model.
I personally like Bosch Aquastar 1600H model as it is an affordable gas water heating appliance, and it offers an innovative technology, using the energy from the water flow to ignite the spark. This is called hydro-generated ignition where the small turbine is used to generate the electricity. This is what allows the water heater to operate without a standing pilot, electricity, or a battery.

Disadvantages

Disadvantage is that it provides only 4.3 gallons per minute of hot water, which is enough for one bath homes only. Too bad, as many modern homes, with standard family size have two bathrooms. Also, it doesn't offer the display panel on the front cover, which is very beneficial to monitor the temperature and to diagnose if there is a problem.

As it has only 0.8 EF, energy factor, Bosch Aquastar 1600H is not qualified for Energy Star, or high efficiency recognition. That means no government tax breaks.

User Reviews

Bosch hot water heater 1600H provides decent savings when compare to the standard tank type water heaters.
This Aquastar model is easy to install; it provides hot water fast, runs quiet and smooth.
Minimum pipe size for maximum performance is a must. Otherwise you will not have the water hot enough.
It requires minimum flow to operate. If you have a screen on the faucet you might have to remove it. It doesn't work well with the flow restrictors.
Hot-cold sandwiches when the water flow inside the home plumbing fluctuates and when the unit turns off often. It has to be reset it manually.

The price

You can buy Bosch Aquastar 1600H model online for approximately $700, as brand new, or $400 factory-reconditioned.

Aquastar 2700ES review

Advantages

Aquastar 2700ES model, is the best Bosch water heater, and top of the line tankless model. 2700ES model is the wall mounted, power vent model that allows flexible installation with the horizontal and vertical venting. This is an indoor unit, but with a purchase of the outdoor installation kit, 2700ES heater can be installed outdoor also. The unit is approved for installations up to 8000 ft.

Bosch Aquastar 2700ES uses the electronic ignition, has a powerful burner, sealed combustion chamber, is equipped with a primary fan, mixer, and secondary fan, for better water heater performance and efficiency, so it can meet the Energy Star requirements. This is a high efficiency, eco-friendly heater, which operates with the reduced NOx gases.

With its 7 gallons per minute of hot water, Bosch Aquastar 2700ES is designed to supply your shower, washing machine and dishwasher simultaneously, and even for variable flow applications.

One of the great features 2700ES offers is the LCD display. It shows the temperature, you can set the temperature, it has a flame indicator, power bar indicator, error indicator; you can use it to measure CO2 but with the installed combustion cover, to program the unit, control board diagnostics, fan speed adjustment and troubleshooting.

Disadvantages

Aquastar 2700ES model, as the best Bosch hot water heater with the sophisticate technology, is also the most expensive one. You have to pay $400 more that what would you pay for Bosch Aquastar 1600H model. The price range is between $1100 and $1500, depends on the store.

User Reviews

One of complains was that Bosch Aquastar 2700ES didn't perform well in colder climates.
Hard to find replacement parts.
Expensive vent kit.
Silent and space saver.
Plenty of hot water.
Expensive unit.
Great on gas.
Easy installation with many options.
This product qualifies for up to $1500 Federal Tax Credit (30% of purchase and installation).
2700 ES is eligible for rebates from the utility company.
It is not that good for hand-washing and short bursts.

One is for sure: the best Bosch hot water heater is usually the most expensive using the latest technology. My recommendations, based on my experience with water heating, go with the one that is correctly dimensioned, properly installed and offers modulation for steady work... everything else is extra. If you are budget oriented, buy 1600 series, if looking for more gadgets, any Energy Star model (2700 or 2400 series) is good enough.
