Descaling Your Tankless Hot Water Heater
Jan 9th
Tankless De-Scaling
|
Have a Tankless hot water heater? You should consider descaling the system. Each manufacturer recommends a different technique so it is best to look at you particular units manual before you do anything. You should be able to find instruction manuals for 99 percent of the tankless systems out there on this site (email me 
if your is not here).
Generally to preform the descaling process you would need to shut off the water and disconnect both the incoming and outgoing water pipes, also make sure to unplug the unit so that it doesnt fire and try to heat the cleaning agent. Then with a small pump push vinegar through the system and catch the fluid that comes out the opposite pipe. Personally we use a rubber hoses on both the input and out put pipes. The Rubber pipes are used so that two hose clamps can be used to trap the vinegar with in the system. Let the solution sit for about 20 minutes and then remove the clamps and turn the pump back on to flush out the buildup. Using the same pump flush the system with some pure water to clear out the cleaning solution. Simply reassemble everything and plug the unit back in and you will be back in business with a noticeable jump in heating efficiency.
Please read your systems manual before preforming this procedure, some units cant be flushed at all or it needs to be preformed by a specialist to retain warranty. If you have any doubts call your tankless manufacturer.
The Tankless Hot Water Myth

The Tankless Myth |
We have heard this SO many times that I have to try and explain why its completely just a misunderstanding.
Here is a version of the myth “because the water is heated instantly at the unit you will always have to wait for hot water at your tap” or “you have to run the water for a minute or so to get the hot water so its not really instantly hot”.
For some reason many people seem to think that these tankless systems are able to provide hot water at the tap instantly. We have even heard people claim that tankless hot water heaters are not environmentally friendly because you have to run the water for a period of time before the hot arrives.
Figure one.
From this image you can you can see the flow that water takes from a tankless to a tap. The black bar represents insulation, when no one is using hot water the insulation works to keep the existing water in the pipe hot. Over time this water does get cold, by morning the pipe will contain nothing but room temperature water. When you turn the hot water tap on it has to push all the cold water out of the tap, once its gone then you can get the warm water.
Figure Two.
From this image you can see that hot water needs to take the exact same route that hot water from the tankless must take. Therefor it has to push out all the cold water currently contained in the hot water pipe before the user will get hot water and thus there is really no difference between the two systems. Well one is much more economical and energy efficient then the other.
No one keeps there car running all night so that it hot in the morning why keep water in your house hot 24 hours/day? Tankless water heaters solve this problem, and there is practically no noticeable difference between the systems, well that’s not true there is a numerical one on your gas or electric bill.
Tankless To Traditional Comparison Chart
Dec 5th
Tankless VS No Tank |
|
| Tankless Water Heaters | Traditional Water Heaters |
 |
 |
| Generates A Non-Stop Supply of Hot Water On Demand | Slowly Heats Cold Water At The Bottom Of Tank As Hot Water Is Depleted |
| Heats Water Only When Needed! No Energy Wasted On Keeping Hot Water On Standby | Burners Turn On and Off 24/7. Wastes Energy When It Is Not Needed |
| The Standard Tankless Water Heater Is About The Size Of A Suitcase and Mounts On Your Wall | The Traditional Water Heater Is About The Size Of A Small Refrigerator. The Unit Takes Up A Lot Of Space |
| A Tankless Water Heater Will Last At Least 20 Years | A Traditional Water Heater Needs To Be Replaced In 10 Years |

- The Rinnai Water Heater is one of the most advanced water heaters available. It supplies hot water continuously at the temperature preset in the unit or at the temperature set on the optional remote controller(s). Installation of remote controller(s) are recommended for optimum performance.
- The Rinnai Water Heater never runs out of hot water. While electricity, water and gas supplies are connected, the Rinnai Water Heater produces hot water whenever the hot tap is open.
- The gas burner lights automatically when the hot water tap is opened, and goes out when the tap is closed. Ignition is electronic, there is no pilot light. When the hot water tap is off, no gas is used. You save energy and money with the Rinnai Water Heater.
- The sound (noise) level from the Rinnai Water Heaters is very low.
- The Rinnai Water Heater is a very compact direct vented device. It saves valuable floor and wall space.
- The Rinnai Water Heater incorporates a device to minimize temperature fluctuations (cold water sandwich effect) when the water is off, then on again. This effect can be eliminated by installing the Rinnai Water Heaters with a circulation loop with a small storage tank.
