Always make sure your gas pipe is 3/4 in or larger. Also, set the temp as low as you can, to maximize the hot water flow.

First of all what kind of flow rates are you running? Low flow fixtures? Also when you installed it did you have your gas pressures checked? This unit should have no less than 4"WC at all times.

If its gassed properly, and not throwing any error codes, Then the water should be no issues.

The length of a pool is 10 ft, the width is 10 ft, the volume is 2,700 cubic ft. we are trying to find out the height.

V = L x W X H
2700 = 10 x 10 x X
2700 = 100 x X
x = 2700/100
x = 27

You should be able to do that in your head.

Bosch Aqua-star tankless water heater had water on gas valve, dried gas valve, I have a spark but will not light

Water in the gas valve is DANGEROUS! The major question is did the water come from a leaking heat exchanger or the product of combustion? If it is from the heat exchanger it may be covered under the warranty (if the installation is proper). If it is from condensate in the flue pipe, it is from an improper installation. If you go to you can find a service provider in your area. I service a very large part of NY, some of NJ (Northern) and all of CT.

Sounds like scale build up in your hot water heater. Aqua-Pure makes a nice scale inhib thats installed on your cold water supply to your hot water heater. Parts and all is about $150.00. Add labor and your set unless you can solder then its a DIY. Homedepot sells the filtration device by Aqua-Pure.

Shower will not heat up. Creda Aqua 9.5e - was working fine but now no red neon indicator and cold water only. I have checked power going into unit and is ok.

May have a tripped thermal overload or blown fuse. Some overloads reset automatically but some will have a red button to reset it with. Some have to be replaced.

No hot water? How can we reset?

This happens with Nortiz heaters. They just **** out. Likely the installation is very bad, but the unit can not tolerate that and it just dies. I recommend getting a Bosch 2700 or 715. If you want great efficacy, get the C-800. But follow the instructions! If it is installed correctly and you have the CO2 levels adjusted when it is installed, you will be very happy.

Not really a problem, I wanted to know if I have one installed in my hair salon will it be as good as adding a Tankless water heater?

it depends how much water you use. you may want a 5 gallon model. the tanklwss heat the water as needed and the tank kind heat justr the 2 1/2 gallon so if you use alot of water go with tankless most of the tankless are gas so you would need a supply and exhaust

Does grundfos rcp96 pump work with bosch 2400 eo tankless heater?

What is your reason to have a recirc line on your water heater does the heater sit to far away from a certain fixture? If you put a pump on your tankless waterheater then your heater will continually fire till the call for hot water is stopped. Yes you normally do need a seperate line installed for a recirc line usually from the water heater to the farthest fixture away. If your problem is taking to long to get hot water then I suggest installing a second heater closer to problem area.

Is there alot of problems with bosch aquastar 2400

Bosch has had problems with these heaters for sure. They are the best known thing out there in the market.They are mostly responsible for the bad rap being given to all tankless heaters, but a big part of the problem is installation. They are being sold to homeowners at box stores as DIY kits. These are not units to be homeowner installed, venting and fuel requirements are different from regular heaters and they will not function correctly if improperly installed. I have installed several of the Rannai units over the past few years without any issue whatsoever.
