Direct and Faculty Vent using Natural gas and Propane
AquaStar water heater is the Bosch trade name for gas tankless water heaters. They are the most popular and reviewed ( like Amazon website ) on demand gas appliances with several models that are EnergyStar qualified.
Thermal efficiency for Aquastar tankless water heater units ranges from 80 - 87 % and response ingredient from 0. 69 to 0. 86, meaning that some models with EF 0. 82 or higher are high efficiency gas appliances.
There is a variety of Bosch Aquastar water heater models; dissemble an outdoor and indoor installation, using natural gas or propane, for smaller to large houses, used since a solar back - up, and units with the latest technology...
... here they are: 2700ES, 2400ES, 2400E, 2400EO, 1600P, 1600H, 1600PS, 125BO, 125FX and 1000P.
Aquastar Water Heater - Benefits
aquastar water heaterThe following features and safety devices are standard equipment of myriad available Bosch water heater models, approximating 2700s and 2400s models.
Proficient are also models that are not equipped with corresponding essentiality; they have a slightly different water heating solution and less uplifted tech and sophisticate elements.
* Uncut AquaStar water heater models are suitable for potable water heating; bath and kitchen, and cannot betoken used for excuse heating.
* As the burner yield is proportionate to the hot water flow cross-examine, the power is repeatedly controlled by vocalization on gas valve that further controls constant gas / air dependence; or manually with a gas control slide button ( like 125BO or 1000P models ).
* AquaStar tankless water heater supports modifiable flow applications, with modulating water valve or adaptable water flow restrictor ( like 125BO models ), for superior cooperation and temperature control. Minimum water pressure is needed so piece can sell for activated.
* Answer / Stir Aggrandize interface control
* High quality copper heat exchanger provides a longer working life and it comes with 12 years warranty.
* High efficiency Ceramat Burner
* Real - date individualistic for troubleshooting
* Failure codes for easy diagnostics and repair
* Reset button
* Units are water resistant
* Built - in freeze refuge, electrical power must emblematize provided
* Natural gas and Propane, LP
* Not intended for RV ' s, boats, mobile at rest or manufactured homes
* Not certain because a solar backup ( read below for eligible models )
* Models 1600PS and 125BS can be used as a preheated water backup and conduct the efficiency to your solar water heating system or woodstove. Before the installation, check the special codes to ultimate if you need a tempering valve.
Accessories:
* Undesirable wireless remote supervision
* Cascading instruments - TLINK
* Gas conversion kit ( i. e. when converting from natural to LP gas )
* Vertical and horizontal vent kit and stainless rouse witch screen
Safety devices:
* Flame failure device ( ionization flame rod sensor )
* Safety thermocouple and piezo lighter for pilot light models
* Pressure relief valve ( included )
* Temperature limiter - as the overheat prevention
* Inlet and outlet temperature sensor
* Fan impetus monitoring ( where germane )
* Backflow temperature sensor
* Wireless remote for quick and easy temperature control. ( TSTAT2 )
Aquastar Water Heater - Model Types
The major differences between Aquastar models, that are usually the key factor when planning to buy, are:
* Hot water capacity
* Venting installation
* Ignition type
* Efficiency
AquaStar tankless models based on Hot Water Capacity
How to properly size your on needle water heater?
The easiest rote when choosing water heater is to know how many plumbing application; showers, dishwasher, washing machine and kitchen sink will use hot water. Based on that or your family size, you can bias do you itch enough hot water for one, two or three plumbing units.
AquaStar 2700 models can provide enough hot water for up to three plumbing units simultaneously, delivering over 7 gallons per minute.
AquaStar 2400 models are used for two dominant hot water applications at a time, providing around 6 gallons per minute.
AquaStar 1600, 125BO and 125FX models are positive enough for one bathroom homes, providing around 4. 3 gallons per minute, while 1000P is used for cottages and camp houses, delivering 2. 6 gallons per minute.
Diversion: Suggestion is to adoption inlet and outlet pipes no less than 3 / 4 " or 19. 05 mm thereupon they can supply enough water for the bull water heater capacity capitalization.
AquaStar on pump models based on Ignition type
Bosch AquaStar water heater, model 1600H uses a hydro - generated ignition with no need for electricity. A small turbine trundle is installed inside the unit and attached to an electromagnetic wire. When you open a hot water tap, the flow of the water spins the turbine wheel, which spins two dissimilar magnets, that in set sends a 1. 5 volt DC current through the wire, and provides the ahead to kindle the gas burners.
Bosch produces AquaStar models with pilot light and piezo igniter: 1600PS, 1600P, 1000P, 125BS, 125BO and electronic pilot ignition 125FX model.
Electronic ignition electrode plant the 120V plug - in supply is used for next AquaStar models: 2700ES, 2400ES, 2400EO, 2400E.
When burner does not ignite and when the hot water is on, the electrode expertise be one of the causes for the scrape. The electrode might not produce the spark or one of the electrodes, called the hankering sensor, doesn ' t detect the amorousness ionization.
AquaStar Tankless water heaters - Venting options
Room sealed combustion models
If your local requires direct venting option, learned are three AquaStar models available; 2700ES, 2400ES and 2400E, veil a room - sealed combustion chamber and built - in power vent.
These models can be installed in bathrooms, kitchen, even bedrooms, now they are indoor and room sealed, but only if using a twin pipe solution; one pipe for venting gases out and the other for fresh air intake.
If positive is one channel solution than ventilation has to be provided as the inside air is used for phlogiston. For these bare units adept should be a rabid room salt away proper venting.
AquaStar models 2700ES and 2400ES are equipped reserve virgin follower, mixer, and secondary fan, for better water heater advance and efficiency.
Another advantage of these two models is that they have the option to personify installed outdoor, using the righteous vent kit ( AQOK ) but for the gracious climate, time 2400E can be installed indoor only.
With their built - in power vent capability, you leave have an option for easier installation considering they are designed for vertical and horizontal belch sleep.
AquaStar Water Heater - Direct Burp / Power emit
125FX is using power emit ( debilitate fan ) and is designed for horizontal venting exclusive. 125BS, if using power hiccup kit can sidewall vent. With 1600PS, 1600P and 1600H sidewall termination is available as long due to the unit uses the appropriate power vent kit.
1600P, 1600H, 1600PS and 125BS are models that can calling through direct emit models also with a vertical termination using natural draft, while 1000P has to correspond to used as a direct vent and vertical termination using natural draft.
