Tankless water heaters

Tankless water heaters pros & cons

Tankless Water Heaters or not?

I’ve been getting a few questions about the subject of tankless water heaters lately.  I’m not much of a salesman since I talk most of my customers out of the bigger job of converting to a tankless water heater.  Under most circumstances for most homeowners it just simply does not make very much sense to me.

  • Tankless water heater pros

    • Never ending hot water (in theory)!  In some households that initially sounds like a huge plus… especially households with kids that like long showers.
    • Take up less space and can even be mounted on an exterior wall or in an attic
    • Have a lower cost per year to operate (though, as I will explain later, the long term cost is much higher)
  • Tankless water heater cons

    • Requires electricity to operate… no electricity = no hot water
    • Initial cost is much higher
    • Long term cost is higher
    • No in home water storage tank.  With a 50 gallon traditional tank water heater, in an emergency situation (earthquake, power outage, civil unrest…) you would have 50 gallons of clean drinkable water in the house.  With a tankless water heater you will have none other than what is in the pipes.

A tankless water heater requires a larger gas line than a traditional water heater, it requires electricity, and it requires special venting. Due to this a typical cost to covert from your existing tank water heater to a tankless water heater is around $3500.00. This price can vary depending on your particular situation. A typical price to replace a standard 50 gallon water heater is $920.00. So the difference in initial cost is $2580.00 (average costs).

Tankless Water Heaters – Brands:

The Noritz NR71 is an adequate tankless water heater for a small home and has an EF (energy efficiency) rating of 0.83.  The Bradford White 50 gallon water heater model #M4TW50T6FBN has an EF rating of 0.67. I calculated the cost per year to operate each of these units by using the information from here and here and found the Nortiz will cost your $81.44 per year less than it would to operate the Bradford White 50 gallon. The initial cost of $2580 divided by the cost per year of $81.44 shows it will take you 32 years before you hit the break even point.  And honestly you will never break even since you will have to replace that tankless water heater at least once during that time.

There are circumstances where I think tankless water heaters are okay. If you are limited in space and need to free up that water heater closet.  If you can afford the space and money to store water by some other means for emergency situations.  And last but not least, if you are insistent that you want one and are willing to pay?

As a side note, if you are running out of hot water for your showers it can often be remedied by simply replacing your existing water heater with one the next size up or with a larger “first hour rating”.

Tankless water heaters can be a terrific choice!

bleach dissolves hair

Bleach dissolves hair!

Did you know that bleach dissolves hair? It’s true! This is due to the chemical make up of the two. Bleach is a “basic” chemical and hair is “acidic”. The neutralization reaction between an acid and a base produces a salt and water. Bleach can dissolve any fiber that has acidic properties.

Next time you have a bathroom sink, shower, or bathtub draining slow try pouring a cup of liquid bleach into the drain. Be sure to rinse off any metal finishes with a little bit of water so they wont get damaged. After about a half hour any hair the bleach is in contact with will dissolve. Bleach dissolves hair and it takes a bit of time. If it doesn’t get rid of the stoppage completely then try another application of a cup of bleach.

This may not always work. There are many other things that can clog a drain line… floss, food, soap scum, hard water, GI JOE’s, etc… If the bleach doesn’t work give me a call. I’m always happy to come fix your drain. But hopefully the bleach tip will save you a few calls.

Liquid bleach is much less expensive than bottled drain cleaners… and for hair stoppages it’s much more effective (which usually bathroom sinks, showers and tubs are hair stoppages).

Caution: Of course you should always wear protective clothing, gloves, and goggles when handling chemicals such as bleach. Please be cautious!

(Edit: If your drain is completely stopped and is not draining at all it is best to call a plumber. Any chemical, if left to sit in a pipe, if it is unable to clear out the stoppage it has the potential to cause further problems. Bleach is less likely to cause any problems when compared to other chemical “drain cleaners”. But if the drain isn’t draining at all then the bleach, or any other chemical, will not be able to get down the drain to the problem area. Bleach dissolves hair but be careful!)

It’s best to do a plumbing job right the first time

When it comes to a plumbing job it really pays to  do it right the first time!

I had a couple of kitchen drain calls the other day that each had problems caused by previous poor plumbing work done.

In one case a laundry line drained into a sump pit and then was pumped into the kitchen drain line under the house. It was connected to the house plumbing system improperly, which is causing the water to overflow into the kitchen sink and then the water in the kitchen drain trap is siphoned out. With no water in the drain trap, and therefore nothing to trap the sewer gases in the sewer, the house is filled with a strong sewer odor. This may seem like a simple plumbing job but you want to handle it correctly.

The Second Plumbing Job

On the second plumbing job a laundry sink is hooked into another drain line improperly, and is also undersized. The home owner complains of a lot of water backing up into the laundry sink when the washing machine drains.

In both cases I was able to provide a temporary solution to the plumbing job by cleaning the drain with a snake. However, both will have problems again soon due to the improper installation of the plumbing. I can fix the problems by installing the plumbing properly, but in either case this is not an inexpensive project.

When having a plumbing job done make sure you have a responsible, professional, and licensed plumber perform the work.
