Best Way To Install A Tankless Water Heating System

Action 1: Run a Vent Pipe

If switching out an old warm heating unit with a brand-new tankless hot water heating unit, making use of the very same location will certainly reduce extra actions (vent pipe, pipes and gas line extensions). If mounting for brand-new building, locate an area near an outside wall to run a vent pipe. A vent pipe must run from the tankless water heating unit to an outside place and must be vented downward to stop aspects such as water from entering into the pipeline. Vent pipes could range in diameter. If an existing vent pipe does not fulfill the effective measurements of the new tankless warm water heating system, a brand-new pipe will certainly have to be run.  

Note: Some designs require different water pipes for fresh air consumption. These versions will certainly require extra thimbles and thimble holes. If you already have a system installed but need repairs or maintenance, simply call for one of our professional plumbers. 

Step 2: Cut Holes

To install a brand-new vent pipe, measure the interior and exterior walls for thimble holes. Cut gaps making use of a saw. For the examination of the thimble. DO NOT set up thimble up until vents have been set up and angles have been inspected. When thimbles have been mounted, move the vent water pipes into thimble tightly. Note: Make sure to seek advice from the directions of the specific storage tank design for regional and nationwide code demands. 

Step 3: Mount the Heater

As soon as the brand-new vent piping has been finished, it’s time to position the tankless warm water heating unit. Make sure the container lines up with the vent water pipes(s).  

Note: If setting up in a poured concrete slab or mortar basement you certainly should affix wooden beams to a joist (a wooden assistance beam that runs along the ceiling), in order to connect a backboard. Step the backboard to the accurate dimensions and affix to the beams. Align the tankless hot water heater unit with the vent pipeline(s) and screw it into place. 

Step 4: Attach Water Pipes

New water pipes have to be gone to provide the tankless warm water heating unit with water. When connecting new copper pipes, completions of each pipe have to be cleansed with an emery towel. Secondly, use soldering flux to the end of the water pipes and slide the pipe into the fitting. Use the heating lantern to the installation with the inner flame tip for 10 seconds. As soon as the metal is hot enough it is time to apply the solder. Touch the solder to the joint and function your way around the installation on both sides until the joint fits.  

Note: A different isolation valve set allows for less complicated upkeep and a comfort shutoff stops tension accumulation. Tankless water heater could be electric or gas. For gas tankless water heater units, T valves need to be mounted to an existing gas line. The moment a T shutoff is set up, a corrugated stainless-steel gas line needs to be flown to the tankless warm water heating unit. A gas turned off valve needs to be affixed to the line just before hooking up to the sediment catch (the brief section of pipeline operating downward under of the storage tank). The moment everything is properly done, utilize a delicate gas sniffer to spot any type of gas leaks.
