Difference Between Bosch 2700ES and 2400ES Tankless Water Heaters
If you live in Florida you should be able to run three showers at the same time. If you live in New York you will only be able to run two showers and a sink at the same time.
Together they are considered to be the top-of-the-line tankless water heaters on the market. They both use the same burner technology and sit in the same "World 2" chassis.
The cost difference between the two heaters is only $110. However, there may be a higher installation cost for the Bosch 2700ES heater. Since the 2700ES is capable of a higher BTU input, it may require a larger gas pipe line than the 2400ES requires. Before purchasing either the Bosch 2700ES or 2400ES tankless water heater, you should first check the gas line sizing chart in the Installation Manuals to ensure that you understand the gas line requirements.
For example, the Bosch AquaStar 2700ES-NG (Natural Gas) can only run about 15 feet on a 3/4 inch Black Iron pipe gas line. The Bosch AquaStar 2400ES-NG can run about 25 feet on a 3/4 inch Black Iron pipe gas line.
Other than the gas line requirements, the Bosch AquaStar 2700ES and Bosch AquaStar 2400ES heaters should have the same installation costs. They both require 3" Stainless Steel Venting.
