What they mean is that it is certainly efficient to avoid heating water when no one is using it. </P> <P>But if water usage is high, a high-BTU tankless water heater may consume more total energy than a large but more conventional oil or gas fired hot water tank and burner.</P> <H2><A NAME="Operation"></A> Tankless Water Heater Operation & Characteristics</H2> <P><a href="https://inspectapedia.com/plumbing/Instant_Flow_Tankless_0113_DJFs.jpg"><img src="../plumbing/Instant_Flow_Tankless_0113_DJFs.jpg" ALT="Instant Flow Tankless Water Heater installation © D Friedman at InspectApedia.com " width="480" CLASS="Image_Standard" /></A>As the name suggests, and as you can see in our photo at left of an electric Instant-Flow water heater, tankless water heaters have no tank, and therefore no storage capacity at all. When the faucets and fixtures in the home are idle, the water heater is dormant.</P> <P>No stored hot water means no standby losses, and,<EM> if you match the heating capacity of your tankless heater to your hot water flow rate requirements</EM>, there is no delay in hot water supply and no running out of hot water.</P> <P>The Instant-Flow® water heater shown is a Model S-48L/240 240-volt unit rated at 4800 watts and is installed on a 20-A electrical circuit.</P> <P>Tankless heaters are supplied in all-electric models (shown here) and gas (or possibly oil) fired units that include a burner, heat exchanger, venting system, and the necessary controls.</P> <P>When a hot water faucet is opened or the dishwasher or clothes washing machine calls for hot water, the tankless heater detects the water flow and ignites the burners.</P> <P>These powerful burners quickly heat the water inside the small diameter heat exchanger. As hot water is drawn out, fresh cold water is drawn in and the cycle continues. A significant advantage of this system is that you can't empty all of the hot water out of the tank because there is no tank - just continuous hot water.</P> <H3>No Stored Water</H3> <P>The other major advantage over conventional water heaters is energy savings. Tankless water heaters have no large reservoir of water that has to be kept hot around the clock in case hot water is needed.

Plenty hot at sink and no heat and loss of pressure at shower.</p> <blockquote> <p class="recent-comment-hdr">On 2018-01-31 - by (mod) - </p> <p>It's an interesting uncommon problem about what you asked. Demand water heaters or tankless water heaters have limited flow rate. So when the hot water flow demand is increased by opening an additional faucet You're simply diverting some of the hot water to another location and reducing the flow at each.<br> <br> take a look at the installation manual for your water heater and you may note something interesting. The manufacturer often recommends specific dedicated water supply piping </p> <p>To maximize the input flow rate at the water heater. so particularly in older homes where the water heater is a retrofit we often find that the input to the water heater is quite Downstream from the supply source and That may limit the hot water flow rate out of the heater.<br> <br> You can increase the water pressure to increase the flow but of course if you exceed the rated input flow rate for your particular water heater your water may not be hot enough.<br> <br> It's also possible that the heating coil could be partially blocked by scale. If that's the case descaling will significantly improve the water flow.<br> </p> </blockquote> <H3>Question: water pressure problems with tankless water heater</H3> <P>I recently installed an electric (120 amp) tankless water heater in a cabin - it actually has 6 ganged heating coils that turn on incrementally as the demand dictates. I also installed a scald less shower faucet - which (I think) decreases the hot water draw when water pressure decreases.</P> <P>My dilemma is: two or three times during a typical shower, the water temperature will increase rapidly (too hot), and then decrease rapidly (too cold) - and then settle at the "agreed upon" temperature for a minute or two. The water system is on a residential well that uses a 40-60 lb pressure switch.</P> <P>I theorize that when the pressure approaches the low (cut-in) point, the faucet demands more hot water (which causes the tankless heater to crank up more heating coils), but about the time that new hotter water reaches the shower (about 13 seconds from the water heater to the shower head) the pressure increases toward the 60-lb (cut-out) range - causing the faucet to demand less hot water - causing the water heater to shut down some of the heating coils.</P> <P>So, If I set a closer differential between the pressure switch cut-in/cut-out pressures (like maybe raising the cut-in to maybe 50 lbs), could I eliminate that yoyo effect? Or could there be a different cause? - Cabin Jack 1/19/2012</P> <blockquote> <H4>Reply:</H4> <p>Jack, Why not install an automatic mixing valve to regulate the temperature regardless of water pressure?</p> <p>Also see <a href="https://inspectapedia.com/plumbing/Tankless_Water_Heater_Repair_Guide.php">TANKLESS WATER HEATER REPAIR GUIDE</A> where we discuss other reasons that hot water temperature may vary when using an instant or tankless water heater.</p> </blockquote> <H3>Question: which hot water source is better, gas or electric?</H3> <P>I am thinking of replacing our hot water tank: which is best gas or electric? would prefer electric to avoid venting - Sid Archer 10/7/12</P> <blockquote> <H4>Reply:</H4> <p>Sid there is not a single right answer to which type of water heater is best, as you want to match the heater to the intended use. Depending on where you live, electrical rates may make gas fuel look less costly to operate, possibly more costly to buy and install, including cost of a chimney or vent system.</p> </blockquote> <H3>Question: relief valve requirements for tankless water heaters</H3> <P>(May 11, 2015) Anonymous said:<br>Dose a gas tankless water heater require a pop off valve?</P> <blockquote> <H4>Reply:</H4> <p>Good question Anon.</p> <p>Some tankless water heaters such as the POWERSTAR AE7.2 Point-of-Use Electric Tankless Water Heater and also the Rheem Tankless Electric RTE 13 are advertised as not requiring a pressure/temperature relief valve, but even there the manufacturer notes that the TP valve may be required by local codes.</p> <p>But certainly there are tankless heaters that are installed with the valve and that include it OEM. And there are TP valves designed for these heaters such as the Rheem AP12993C Pressure Relief Valve and the Watts Model 3L TP valve. So the answer, as Mark Cramer says, is ... It depends...</p> <p>Though it's always safe and not harmless to add a properly-located TPR valve.</p> <p>Give us the brand and model number for more details.</p> </blockquote> <br> <P>...</P> <p><A NAME="MoreReading"></a><STRONG>Continue reading</STRONG> at <a href="https://inspectapedia.com/plumbing/Electric_Shower_Heaters.php">ELECTRIC SHOWER HEATERS</A> or select a topic from the closely-related articles below, or see the complete <a href="#MasterIndex">ARTICLE INDEX</a>.</p> <P>Or see these</P> <H3>Tankless Water Heater Articles</H3> <UL> <li CLASS="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Hot_Water_Speedup.php">HOT WATER CIRCULATOR PUMP SPEEDS DELIVERY</A></li> <li CLASS="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Tankless_Coil_Guide.php">TANKLESS COILS</A></li> <li CLASS="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Tankless_Water_Heater_Guide.php">TANKLESS WATER HEATERS</A> <UL> <li CLASS="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Electric_Shower_Heaters.php">ELECTRIC SHOWER HEATERS</A></li> <li CLASS="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Tankless_Water_Heater_Capacity.php">TANKLESS WATER HEATER CAPACITIES</A></li> <li CLASS="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Tankless_Water_Heater_Conversion.php">TANKLESS WATER HEATER CONVERT TO?</A></li> <li CLASS="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Tankless_Water_Heater_Installation_Guide.php">TANKLESS WATER HEATER INSTALLATION</A></li> <li CLASS="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Tankless_Water_Heater_Installation_Cost.php">TANKLESS WATER HEATER INSTALLATION REQUIREMENTS, COSTS</A></li> <li class="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Tankless_Water_Heater_Life.php">TANKLESS WATER HEATER LIFE & USES</a></li> <li class="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Hot_Water_Alternatives.php#MoreHotWaterD">TANKLESS WATER HEATER MULTIPLE GANGED</a></li> <li class="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Tankless_Water_Heater_Repair_Guide.php">TANKLESS WATER HEATER REPAIR GUIDE</a></li> <li class="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Tankless_Water_Heater_Size.php">TANKLESS WATER HEATER SIZE REQUIREMENTS</A></li> <li class="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Hot-Water-Temperature-Adjustment-Controls.php#TanklessHWCtrl">TANKLESS HOT WATER HEATER TEMPERATURE CONTROL</a></li> <li class="LI_Spaced"><a href="https://inspectapedia.com/plumbing/Tankless-Gas-Water-Heater-Screaming.php">TANKLESS WATER HEATER WHISTLE</a></li></UL></li> </UL>  <a name="MasterIndex" id="MasterIndex"></a> <H4>Suggested citation for this web page</H4> <P><a href="https://inspectapedia.com/plumbing/Tankless_Water_Heater_Guide.php">TANKLESS WATER HEATERS</A> at <a href="https://inspectapedia.com/index.php" ><FONT COLOR="#0000FF"><STRONG>Inspect<FONT COLOR="#FF0000">A</FONT>pedia.com</STRONG></FONT></A> -
