Would like to get a estimate for having a new, 50 gallon hot water heater installed. Replacing a 40 gal heater. Need an accurate estimate, considering that code updates may be necessary. Thanks.

I have a Bosch tankless waterheater model 125BO, NG. The pilot went out and will not relight.

Gas water heaters have long been recognized as the most energy efficient of all water heater models. Their heating capacity is twice that of electric water heaters, while the heating cost is half that of electric models. Gas can power both storage type, as well as tankless water heaters. Gas tankless water heaters in fact, are considered to be the most energy efficient of on demand water heater types. They also offer a greater pressure of water, making them suitable for large households where there is greater need for water.
When it comes to tankless water heaters, gas is the preferred fuel choice. The efficiency and operating cost of gas tankless water heaters can depend on whether it is powered by natural gas or propane. When it comes to flow rate too, natural gas tankless water heaters are the clear winners. The only draw back is the cost of purchasing and installing a gas water heater. A gas model can cost up wards of $1000, against $500 to $700 for an electric model. Gas water heater> installation involves complex specifications regarding combustion air supply and venting that have to be met. This raises installation costs. However, with the kind of energy efficiency that a gas water heater promises, homeowners are likely to recover the cost of installation and purchase within one year in the form of reduced energy bills.
There are also safety considerations involved in installing and operating a gas water heater. In earthquakest gas water heater models is up to 85% while that of electric models can be up to 98%.
