Common Installation Issues
Saturday, June 11th, 2011When you have water heaters in the home, you certainly have installation concerns to deal with. Here are some of them:
•Gas Supply
The elimination of the storage tank means that water must be heated rather quickly; that water be heated instantaneously as it goes through the heat exchangers. The process requires greater BTUs and therefore, more gas. There needs to be enough gas pressure and volume. For this reason greater gas piping is necessary. A gas tankless water heater system will modify its burners based on the preset temp and the volume of water you require.
•Exhaust venting
A gas tankless water heater has a sophisticated computer-monitoring system. This often includes the tracking of exhaust temp for cleaner burning and adjusts combustion. Proper venting is essential because the high density heating process must be vented quickly. When the exhaust vent is marked by long runs and numerous bends, this may lead to system shutdown.
•Pipe freeze
The outdoor model tankless unit can be susceptible to pipe freeze. Most outdoor tankless water heaters come with an interior electric heater to guard the heat exchanger from extremely low temperatures and prevent damage to them. Meanwhile, the same is not said for the remainder of the plumbing. It’s imperative to retain the water pipe contributing into the tankless water heater short and protected from freezing temp due to the insulating material that wraps it up.
•Water Pressure
Beneficial water pressure is ideal for a tankless unit but there is also such a feature as excessive water pressure. There are many reasons for this but water pressure in excess of 100 PSI (pound-force per square inch) places additional stress on all plumbing components. This stress might be the cause of plumbing valve failures and connections both outside and inside the tankless water-heating unit ahead of time. The frequently recognized water pressure range is between 60-70 PSI, and this can be easily maintained with a water pressure regulator.
Become familiar with your tankless alternatives
Apart from the water heating necessities and cost concerns, installation choices might be another thing you can base the selection of a gas tankless water heater option on. The cost of the unit plus the cost of installation-including toil and components: pipes, brackets, etc.-may differ considerably depending on the type of tankless unit you choose.
