Depending on which model gas tankless water heater you have that is running off LP gas you could get a close estimate on the amount of LP gas that would be consumed on a daily basis.
If you had a Bosch 1000P LP gas tankless water heater that has a maximum potential to deliver 74,900 BTUs at its highest fire you could calculate the usage of gallons per minute (GPMs) versus the BTU usage at that rate of burn and get the amount of time it would take to use 1 gallon of LP gas.
Say you run the 1000P LP gas tankless water heater 1 time a day just for a shower. The shower flows exactly 2 GPMs so the tankless water heater would be running at about 74,000 BTUs during this time and then figure on an average you stay in the shower for 10 minutes total time so overall you would burn about 1 gallon of LP gas for every 7-8 showers.
These calculations would vary depending on consistent flow and water pressure, length of time the water is running, the temperature outside will have an effect on the tank and gas pressure and also what BTU the heater is running at that time.
Basically this is an estimate for calculating usage of LP gas with a gas tankless water heater. This data is for example only and will hold no bearing on any Bosch tankless water heater as they all vary in BTU usage.
The heat that is produced by the heating elements in the modules sometimes counteracts with the mineral deposits in the water. If there is a high mineral content due to a hard water area then these mineral deposits known as "scale deposits" will over time attach themselves to the heating coils inside the modules.
All Bosch Powerstar electric tankless water heaters should never be descaled with any type of solution such as vinegar, muriatic acid, etc. The use of descalants flushed through the heater does not have much effect on the mineral deposits attached to the elements. Another point of trying to flush descalant through an electric tankless heater is that it will loosen some of the mineral deposits in the heater and will have a damaging effect on the flow transducer and other parts inside the tankless heater that detects the flow of water and will interrupt the signal to the circuit board itself.
The best protection against mineral deposits (scale) forming on the coils in the electric tankless heater is to check the quality of the water in your area before installing and if the water has a high mineral content then it is recommended to install a water softener or scale stopper system. The water softener or scale stopper will filter out almost all of the minerals and treat the water so the electric tankless water heater will have a longer life with less minerals building up inside.

The PCB would recognize many factors in the function of the heater to maintain a steady temperature and all of this is determined on where the temperature knob is set too, the gpm flowing through the heater and the temperature of the incoming ground water.
To obtain the maximum heating potential of the Powerstar electric tankless water heater, it must be wired correctly and have the full required voltage to the unit. The Powerstar AE115 would require 2 independent double pole 40 amp breakers wired with 8 gauge wire and could draw a maximum of 80 amps at full flow through the heater. The Powerstar AE115 would require the home to be supplied with a minimum of a 150 amp service. The Powerstar AE125 would require 3 independent double pole 40 amp breakers wired with 8 gauge wire and could draw a maximum of 120 amps at full flow through the heater. The Powerstar AE125 would require the home to be supplied with a minimum of a 200 amp service.
The maximum inlet water temperature allowed into the heater is 86 degrees Fahrenheit.
The Powerstar AE-115 & AE-125 have had many upgrades and engineering improvements over the years. In January 2007 the AE-115 & AE-125 went from having copper canisters that contain the heating elements to an upgraded Polymer module. The PCB control board was also upgraded to maintain a more steady temperature that works with the heating elements in the polymer modules.
Below are the designated PCB control board part numbers for the units before and after 2007.
Before 2007 with serial #60A 00000 or lower:
Powerstar AE-115 PCB with copper can units, part #93-793777
Powerstar AE-125 PCB with copper can units, part #93-793778
After 2007 with serial #60A 80000 or higher:

These 2 Powerstar units have specific power requirements as the AE-115 would require the home to have a minimum of a 150 amp service to the home and would require 2 double pole 40 amp breakers wired with #8 gauge wire as the unit can draw up to 80 amps when at full usage. The AE-125 would require the home to have a minimum of a 200 amp service to the home and would require 3 double pole 40 amp breakers wired with #8 gauge wire as the unit can draw up to 120 amps when at full usage. Please view this link for the AE115 and AE125 power requirements:
The Powerstar AE-115 & AE-125 models have had many new upgrades over the years. The biggest upgrade was that the canisters inside the tankless heater used to have copper canisters and then in 2007 they were upgraded to poly tanks that are more durable and would handle expansion and contraction of the heat better and would be less susceptible to mineral buildup.
The Powerstar AE-115 is designed for 1 major application at a time and is recommended for installation in homes that are in the southern regions of the United States as the incoming ground water is warmer giving the heater a higher temperature degree rise.
The Powerstar AE-125 is designed for 1 major application and 1 sink at a time and is recommended for installation in homes that are in the northern region of the United States where the incoming ground water is cooler and this heater will be able to give a higher degree temperature rise.
The Manufacturer of the Powerstar AE-115 & AE-125 require that there must be at least 3-4 feet of copper water piping coming from the units on the hot and cold water side before attaching to any pex piping as this is due to thermal expansion.
The Powerstar AE-115 & AE-125 are both UL & CSA approved.

If a battery back up system is to provide power to a Bosch tankless water heater in case of a power outage, the back up battery system must be able to produce a pure sine-wave voltage output to the heater. APC (American Power Conversion Corporation) is one of the companies that offer a line of battery back up systems that produce a pure sine-wave voltage called Smart UPS (Uninterrupted Power Supply).
The APC Smart UPS 750VA or above (SUA750) will produce a pure sine-wave voltage output that is compatible with the Bosch tankless water heaters.
Here are a few other manufacturers and the model numbers of UPS battery back up systems that produce a pure sine wave voltage output:
- Powerware 5115 (500VA or above)
- Tripp Lite SU1000XL
- Cyberpower PR1500
- Belkin F6C100
- MGE Pulsar EX700RT

The reason lies in how the unit controls the temperature. These large KW whole house tankless water heaters are designed to take cool water and heat the water to shower temperature as the water passes through the heater. The heater turns on as flow is detected and turns off when the water flow ceases.
There is a temperature sensor on the inlet water pipe (cold) and a sensor on the outlet pipe (hot). The switch that turns the heater on is a solid state style switch or SCR switch. This type of switch has no moving parts and is very reliable. However, SCR or solid state switches generate heat as they switch electrical current. To cool these switches, they have been located on the inlet (cold) water inlet. So the copper pipes act as a heat sink for the SCR switches. If hot water is passed through the pipes and the heater turns on the SCR switches could over heat and FAIL.
Call us for any applications involving the need to have pre-heated water through a tankless heater. We can provided gas and electric heaters for floor heating or other applications needing to circulate warm or hot water.
