Wasted water!

[ohioshooter]

Is there any solution to having to wait for warm water. I'm used to a water heater with a hot water recirculator which gave me hot water in seconds. These on demand heaters waste way too much water besides the fact that you have to wait several minutes to wash your face. Take the time waiting and multiple it times thousand of homes and we are wasting an enormous amount of water.

Fill a container while waiting for hot water to arrive, use it to water tubs and plants.
Works for us.

[retiredguy123]

It won't save water, but you can reduce the wait time by more than half by turning on the sink faucet and the shower at the same time.

[MartinSE]

There is a method of recirculating the hot water to keep it hot at the shower or faucet. It is slightly different depending if you have a tank or tankless heater.

If you are a DIY type google Hot Water Recirculating, it is not hard. If you are not a DIY type, any good plumber can do it for a few hundred dollars (just a guess, I did my own and it was around $300 total and an hour or two).

We have built 4 homes before. Two had basements with water tank heaters with recirculating hot water. Please explain how to recirculate hot water with a on demand heater and plumbing below the concrete floor. Thanks

We're in the same situation. It might not work with a tankless heater or may void the warranty. Seems like people are using a type of recirculator that installs under the farthest sink and pushes water from the hot line into the cold line. A lot different than the actual loop recirculator. If I had room in the garage, I'd almost consider getting a tank heater just to get a real recirculating pump.

We were going to build a house but ended up buying a 95% finished home. We are living in a rental for the time being. When we tried to spec a build they didn't want to furnish a tank heater and wouldn't begin to talk recirculate.

This topic has been discussed numerous times. On the Search bar above, type "Grundflos and Watts" to see suggestions for a solution. We've had a Watts recirculating pump for several years.

Just a quick question, do you have an on demand water heater?

[Garywt]

Even with our electric water heater it takes a long time to get hot water to a sink or shower. We turn the shower on, go do something and come back for the shower. Anyone we have asked has the same situation. It is like they put a mile of piping under the slab so the water to travel before it gets to you.

Just a quick question, do you have an on demand water heater?

Husband says, "No," it is a conventional heater with a thermostat. He is a retired electrician and installed the pump timer at the shower so that the pump is turned on only when it is time to take a shower.

That’s odd. When we built our house they installed a recirculating tankless water heater and plumbed in the return line. We went through design in December 2020 so maybe things have changed.

We never know. What is a 95% finished home? I would guess 5% means the buyer chooses the color of the interior paint. Changes? I would guess most anything can be changed so long if it is legal and on code-IF YOU ARE WILLING TO PAY FOR IT.

That is what a recirculating hot water system solves. It keeps the water at the faucet or shower hot, if it cools down it recirculates it through the heater until the water is hot again. No water is wasted and it is always hot when you turn on the shower or faucet.

Any good plumber can install it as an after market upgrade. I expect it is less expensive to do it at build time, but either will work.

Running the shower for one minute uses about 2.5 gallons of water and costs about 2 cents, including the sewer charge. I agree that it is wasted water, but the cost is very minimal.

A container? I could fill half a tub of water waiting for the hot water if I didn't have our Watts hot water recirculating pump.That may be a bit of hyperbole.

[coffeebean]

We have our Watts on a timer too and our hall bathroom and kitchen are connected to the Watts pump. Our timer turns the pump on at 6:00 am and turns off at 10:00 pm. Those are the two water sources farthest from the hot water heater in the garage. Must say though, if you want cold water to drink from the tap, you will wait to clear the line of the hot water.

[ohioshooter]

From what I’ve read this still isn’t for a on demand. Thanks

A check valve (cross over valve) is installed under the master bath sink. A timer is on the recirculating pump can be set in 15 min increments. Amazon.com (https://www.amazon.com/Watts-500800-Instant-Recirculating-Install/dp/B000E78XHG/ref=asc_df_B000E78XHG/?tag=hyprod-20&linkCode=df0&hvadid=198079373928&hvpos=&hvnetw=g&hvrand=26647700969922458&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=1025491&hvtargid=pla-350581636251&psc=1)The hot water travels thru hot line loops thru to the cold and returns back on cold one to tankless heater. When shower or sink faucet is operated the check valve prevents back flow of cold water to hot water pipe.

A recirculator may save some water cost, but I wonder how much energy you use keeping the circulating water hot because you will lose heat to the ground and air that surrounds the pipes as the water circulates. Cost wise, I'll bet it's a wash in the end.

The troglodyte

[lindaelane]

I turn on the shower, then undress and lay out clothes. It is hot when I get in.

I brush my teeth with cold water. I can wash my face with cold, or wash my face in the kitchen sink.

I guess accept water down the drain before it gets hot in the shower. The water goes into the sewer, then to the sewage treatment plant, then either goes into the ocean or becomes non-drinking water, e.g., waters crops, etc.

My water bill has not been that much lower when I travel for a month and so do not use the shower or sink.

Everyone can decide what is "worth it" to them - For me, it would be a nice luxury to have hot water very quickly after turning on bathroom taps. However, I do not think it would be worth my spending hundreds of dollars.

[TKS]

How is the water “wasted” if it returns to the Earth’s ecosystem? It isn’t shunted off into outer space. The only waste is the minimal utility fee. That said, waiting is a pain.

The warranty on the tankless water heater is reduced if you use a recirculating pump.

[Blackbird45]

My wife is in a wheelchair, and I wash her back with hot towels every morning, it's more to relax her muscle than to clean. I used to run the water forever just to get it warm enough. Now I have a large bowl I sit it in the microwave for 5 minutes, I put in the towels and snap on the lid. The towels stay really hot for 15 minutes or more. So, depending on how much water you need this could be a solution.

The on demand tankless water heaters save energy/gas at the waste of a little water. Hauling large buckets or tubs of “cold water” isn’t worth my time or within my capabilities.

I step into the shower a little early to get a refreshing cold shower- they say it helps with cardiovascular issues, mental clarity and motivation. Then sit on my shower bench for a very long shower- could be 20-30 minutes enjoying the hot water and the massaging shower spray. I meditate on how grateful to God I am that I have a continuous hot water heater so I can enjoy long showers even when my dishwasher and washing machine are going!!!

And there are soooooo many more dire problems in the world - I am glad i view the water heater as a GREAT THING and provides me moments of peace away from the craziness!!!

Life is too short to stress about the little things - and life is soooooooo wonderful here in The Villages.

[donassaid]

Lowes sells a hot water tank recirculation for a little over $100 bucks that sits on top of your water heater and has to be plumbed in. Works like a charm.

Don't get a circulating pump that attaches to the hotter tank because they cost too much to run even with a timer. Run the hotter from a sink close to where you want hotter first (guest bathroom or kitchen sink). They sell under sink circulators with timers and on/off switch.

An AOC recommendation is to fill a container with hot water and keep it in the refrig until you need some. Then just take it out, pour what you need and keep the rest until later when you need some more.

Villagers don't care about how much water they waste. I submitted a thread about all the sprinklers I have seen shooting water out onto the streets, running in the heat of the day, etc. and my concern for the amount of water being wasted. I was heartily lambasted and trolled by an overwhelming number of responses from Villagers who couldn't care less about the environment.

Absolutely. Call Mike Scott Plumbing. They'll put in a hot water recirculating pump on the water tank and it works like a dream all the way to the back of the house! I paid $495 about 6 months ago.

If there is a cost, it is worth every penny for the convenience of instant hot water where and when I want it.

Hello,
I installed an electric heater under my sink. I bought 12 KW steibel eltron heater. A smaller unit will not work due to water flow rate ( I tried an 9 KW Rheem and it burned out in 2 months trying to keep up.
The 12 KW unit needs 6 gate wire on a dedicated circuit from the breaker box. I had an electrician run the wire through the attic for me ($300). I bought 80 ft of the wire on line for $300. The heater was about $300. Plumbing fittings ~ $75. I don't use either hot water shut off under the sink (one was for faucet and one was for DW). I teed off the cold (I bought shark bite 1/4 turn shut off). One branch to the heater, the other to the faucet. Then teed off the out line from the heater; one branch to the faucet, the other to the DW.

Thank you I’m glad to hear someone finally speaking up & addressing this. I bet our house in Charlotte I ran 2 to 3 gal. everytime I wanted hot water.

A container? I could fill half a tub of water waiting for the hot water if I didn't have our Watts hot water recirculating pump.That may be a bit of hyperbole.

Who are you to call hyperole?

I have a tap under B/r sink which fills container. Takes about 3/4 of a gallon for warm to get there.
I also have an outside storage tank that take diverted bath/shower water from upstairs which I also use on garden.
In winter when full it diverts to main drains.
Also collect rainfall in storage butts from shed roofs.
At our last house we collected rainwater from house roof guttering into underground storage tank which pumped water into house too flush toilets, and also irrigate garden.
Get your own plumbing sorted, and shove your hyperbole where the sun don't shine!

I am not wittier about any wasted water at this time. We selected a new home that was built to avoid going through the build process so it wasn’t a possible add on for us.

Well, that makes sense, obviously everyone in the villages has the same floor plan as you and so THEY are wrong

You know that in some states collecting rain water is illegal, you might want to check.

Do you have an underground storage here? Not sure what the point of that is when the OP is asking how to reduce the time to get hot water to the faucet.

But, thank s fore your rant, I appreciated it, very enlightening.

[72eagleman]

If you put a tank water heater in the garage, it still will take just as long to get hot water to your farthest point. The water lines run under the house so installing a recirculation line would either involve cutting the concrete in the garage to be able to get a pipe under the slab and then route the recirculation line underground outside and reconnect at the farthest point from the heater so the water can recirculate. I
The other option would be to route a pipe up in the attic and back down a wall to reconnect. This may be difficult if you have a block home because the water pipes are inside the wall. As a contractor, I would shy away from this attic insulation because I never wanted water pipes over a living area. If a pipe leaks or breaks, you will have interior damage and depending on where the pipe leaks it can get very costly very fast like $25-50K if it is over a bathroom or kitchen.

[TrapX]

Here is some help understanding what is possible. Either a dedicated return line, or use the existing cold water line.

[lawgolfer]

From what I’ve read this still isn’t for a on demand. Thanks

There are two ways to have nearly instant hot water with an on-demand/tankless system:

1. You install multiple, small, individual, on-demand heaters, at each location where you want instant hot water. In new construction, this means you only have to run one cold-water line to those locations. At the location, you then split the line so as to run cold water to the tap and water to be heated to the on-demand heater. You then install a larger on-demand heater for the rest of the house. You will have a time lag to get hot water to the locations not equipped with a smaller on-demand heater.

2. You install one large capacity on-demand heater for the entire house which fills a small "holding" tank. At the holding tank, you install a recirculating pump. In new construction, you install three lines to the locations where you want instant hot water. One line is cold, the other hot via the recirculating pump, and the third a return line to the holding tank.

In a remodel, you install a Watts pump at the holding tank which continuously circulates water in the hot water lines and returns it to the holding tank in the cold water lines. The Watts system requires that a manifold, a simple tube with one-way valves, be installed at the faucet that is furthest from the holding tank. If the hot water line is "split" and hot water is sent in two directions inside the house, you will need a manifold at the end of each of the lines. This is common in The Villages.

Using an on-demand heater and a holding tank is very efficient. Instead of having a regular water heater of 40, 50, or 60 gallons, all of which must be kept hot at all times, you will be heating only a small holding tank of, perhaps, 5-10 gallons depending on the size of your house. Any plumbing supply house can advise you as to the size of the holding tank.

I know it is an oxymoron to add a tank to a tankless water heater. However, it works and, with the addition of a recirculating pump, is the only way you can have nearly instant hot water throughout the house when using an on-demand water heater.

exactly. Wish people would pay attention to the clouds ( water trucks) that transports the water over the planets surface only to release it. Even the dirtiest water is purified by earths soil ( coffee filter) to be released into cisterns and aquifiers. Some states claim their drinking water is 80 years old.
Sidenote:
Next time you see thirst parched animals on the african plains suffering from the relentless heat realize that when the heat blows off of the african coast it heads our way to culminate in our hurricane season.

You’re wrong. We very much pay for irrigation water. North of 466, irrigation is potable water. Regardless, those of us South of 466 whose irrigation water is reclaimed, still pay for it.

[OhioBuckeye]

That’s nice but wouldn’t you think with all the complaints about running water & wasting lots of water to get a little in the sink, I would think the contractor would figure something out. This has been a big complaint for several yrs. not saying some people might think why are people so worried about a little wasted water. All I can think of some people might be a little more conservative about how their money is being spent because that’s how they were brought up. We have the same issue here inTexas. But I am an old resident of TV.

Amazing how so many threads circle back to “it’s the developers fault”.

I guess no one is responsible for their own Choices when they buy a house. I even recall someone that said they couldn’t be bothered reading all that paper work when they bought the house, it was the developers fault.

Personable responsibility, seems to be rare

I guess no one is responsible for their own Choices when they buy a house. I even recall someone that said they couldn’t be bothered reading all that paper work when they bought the house, it was the developers fault.

Personable responsibility, seems to be rare

Well said.

I have a recirculation system with a timer on my tankless system. Ask your plumber.

It MIGHT not work - because it might not draw enough water to cycle the heater on.
It MIGHT void the warranty - because of the constant cycling on and off.

Depends on the tankless heater. There are some with recirc built in.

Who are you to call hyperole?

I have a tap under B/r sink which fills container. Takes about 3/4 of a gallon for warm to get there.
I also have an outside storage tank that take diverted bath/shower water from upstairs which I also use on garden.
In winter when full it diverts to main drains.
Also collect rainfall in storage butts from shed roofs.
At our last house we collected rainwater from house roof guttering into underground storage tank which pumped water into house too flush toilets, and also irrigate garden.
Get your own plumbing sorted, and shove your hyperbole where the sun don't shine!

My hyperbole was referring to MY plumbing in MY home. My hall bathroom is the furthest point from the hot water heater so it takes lots of time to get even slightly warm water. Seriously, I could fill a lot more than a container of water before I get hot any water. I think you may have misunderstood my comments.

I'm a snowbird renter. Live in UK. and I was replying to a post that practically called me a liar.

ahem...

I KNEW you misunderstood my post. I was not calling anyone a liar. I was just commenting on what it is like getting hot water to my hall bathroom in MY home.

Is there any solution to having to wait for warm water. I'm used to a water heater with a hot water recirculator which gave me hot water in seconds. These on demand heaters waste way too much water besides the fact that you have to wait several minutes to wash your face. Take the time waiting and multiple it times thousand of homes and we are wasting an enormous amount of water.

I like the cold water on my face down here….:sigh:

There’s no such thing as “cold” water here. :clap2:

Not cheap though.

Not cheap though.

I'd wondered if something like this could be done - it's a small electric heater downstream from the tankless heater, right? How did they tap into the farthest hot water line for the return? How "not cheap" was it?

Typically, you don't need a heater, just a small pump to keep the hot water circulating throughout the house. These recirculating systems come with a sensor valve that connects to the hot and cold water lines under the farthest sink from the water heater. This provides the return. If you hire a plumber, you can probably get the pump system and installation for about $300 to $400.

Sorry but you are mistaken. That doesn’t work with a on demand water heater. Oh and your price estimate, you can’t get a plumber to your house for that.

Yes, I think it is 2 1/2 gallons. So far it works great. There is a manifold with a check valve at each sink. The return uses the cold water line. For some reason the farthest one from the source is the fastest to get hot. Almost instant. Over $3k. Installation took about 5 hours.

You may be correct about the cost. But, at least one company, Aquamotion, makes a recirculating pump system that works with a tankless water heater.

A recirculating pump without an additional heater that holds hot water will do nothing. Think about it.

I wouldn't buy one. But, I think the Aquamotion system pumps the water at a slow pace until the tankless heater comes on, and then monitors the temperature of the water in the pipe to keep it hot. When it cools down, the pump comes on again. So, you always have hot water in the pipes in your house.

Placing the water heater near the front of the garage is largely responsible for the unecessary loss. Placing it near the kitchen or master bath would help efficacy.

Fyi; For my Iris, temperature drop from the on demand heater to the bathroom is about 10 degrees so recirculating will waste energy reheating the under ground lines

I've measured less that two gallons of water run before it is warm at the master shower. About right for brushing teeth.

Since we reclaim waste water, It's not completely wasted. I have no idea how efficient that system is.
