It needs to be flushed!

Well, actually I lied, if it’s less than 2 years old it doesn’t. 

BUT

If your tank is any more than 2 years old it really could use a flush to make it more efficient and clean.  A tank will decrease in efficiency by 2-3 percent a year as minerals build up on the heating surfaces.  These minerals effectively insulating the heat from the water forcing your heater to burn more fuel longer to heat the water. 

The best part is that there is a simple solution.

Flushing a water heater requires that vinegar be circulated though the system repeatedly with a small pump for about 30-40 minutes. The acid in the vinegar eats away the deposits that have accumulated on the walls of the heater revitalizing the past efficiency of your water heater. 

Tankless Flushing

A tankless is incredibly efficient and thus incredibly susceptible to scale and mineral build up.  Thankfully, most tankless systems are installed with flush valves so that this process is easy and fast. 

1. Unplug the unit
2. Shut the water and gas off
3. Hook up the hoses
4. Start the pump and run the vinegar thought the tankless.
5. Your done, just reverse the steps.

Conventional Tank Flushing 

This type of water heater is a bit more difficult, but it is just as important to have the system flushed and cleaned.

1. Unplug if necessary
2. Shut water and gas supply off
3. Drain tank
4. Pump vinegar through system
5. Rinse and flush a second time
6. Done, reverse steps to hook everything back up

That should pretty much clean both types of water heaters sufficiently to bring the efficiency back to nearly factory standards.  It is important to have this done on a relatively regular basis and, by chance we offer a flushing service for 99$ for either system.

Toronto and Area Water Heater Flush – $99

Tankless Isolation Valve Install and Flush – $149   

(cheap tankless installers don’t always include the isolation valves)

Flow rate is an important issue that should be assessed on an individual house basis. A condensing tankless uses the exhaust heat to pre-warm the incoming water; this is good for Toronto and area locations as our winter water temperature is cold. Having cold winter water decreases how much hot water a tankless can produce, so it is important to ensure you get a system that can provide you with the necessary amount of hot water.

We offer free tankless assessments and can have someone come out to your home to assess firstly, if a tankless can be installed, and then, which system would provide you with the correct hot water quantity. There’s no obligation to purchase anything, but if you decide you’re interested we can work out a quote and leave it with you. An assessment takes no longer than 30 minutes.

 This is a complicated system and it will be costly, if you are doing this to save money you probably won’t see a breakeven point for a long time.  If you’re interested and looking at installing a Frankenstein system you are probable doing it for the environment. 

What’s required?

If your installing somewhere in the southern states this will be a lot easier as you don’t have to worry about sub-zero temperatures.  Up here in Ontario it’s a definite issue and there are a few systems that can be installed.  There is the Active Glycol-based system that circulates food grade glycol and transfers the heat via a heat exchanger to the potable water; this is less efficient but the safest and most popular system in Ontario.  The other way is though a drain back system, potable water is forced though the solar collector and drains instantly when the water is shut off.  Both these systems work to preheat a tankless systems incoming water supply ultimately reducing the heat and gas needed to raise water temperature to the desired warmth.

These dual systems are not very popular due to the increased expense but a tankless is well suited and designed for a hybrid system.  If the idea seems interesting but the price too high you should note that they can be installed in stages, tankless first and then the flat plate solar collector.

First there is a inline screen filter that is installed to insure that incoming water is clean and free of debris before running through the heat exchanger. This little filter should be checked every so often, (dependent on water quality) and is a circular mesh screen. Incoming water needs to be shut off and then the screen can be cleaned.

Secondly a tankless needs to be flushed to remove calcium and scale build up in the heat exchanger. If your tankless was installed by a reputable company they will have included a pair of flush valves which make this process quite easy. It’s probably best this be done by your installer but here is a brief rundown of what occurs. Water and gas are shut off and the unit is drained. Then two hoses and a small pump are hooked up to the flush valves and fresh vinegar is pumped through the systems heat exchanger for roughly 30 minutes. This cleans out all the buildup and scale that severely reduces a water heaters efficiency.

Those are basically the two things that a tankless owner needs to perform to ensure maximum efficiency and a prolonged lifespan. Barrie through to Toronto and basically all of southern Ontario have significant concentrations of limestone and thus relatively hard water conditions. A conventional tank can’t be cleaned whereas a tankless can and hot water accelerates the rate of scale deposits.

A tankless water heater will not save you money.

This depends so much on the situation it’s impossible to make any claim that a tankless will not save you money. Here are a few variables that factor in.

1. The price of natural gas varies by Province, City, Country, and even supplier and on top of that there is delivery charges, taxes, and additional fees. A tankless can significantly influence these costs instigating either an increase or a decrease (more often than not its a decrease).
2. The price of the tankless… this varies again with the size of unit, the brand etc etc. Also be careful of door to door conventional tank type water heater sales people, more often than not those contracts are much higher than the actual cost of a tankless.
3. Tankless warranties are pretty similar to a conventional tank type water heater, but…. a tankless is designed to be serviced and have a lifespan of over 20 years. Their heat exchangers are designed to be cleaned of all calcification, whereas you tank type heater is simply designed to be replaced

So take the what you hear about the advantages and disadvantages of a tankless with a grain of salt. If someone has decided it’s not for them and feels it important to rhyme off a few common misconceptions take the time to investigate and see if its right for your home.

This a great program that the Government has in place to help home owners offset the cost associated with upgrading old heating, cooling, insulation and various other systems within a home.  Upgrading old conventional tank type water heaters was one of the major targeted areas that saw huge grants to promote the removal of these systems.  A tankless system is designed to have a lifespan of over 20 years, where as a tank will be lucky to last 12-15 years.  The efficiency comparison between a storage tank system and a tankless is roughly around the 40% mark.  Yes a tankless will be more expensive but it will save you money, and even though that money is hard to see a tankless systems is a proven money saver. 

You Have Never Had An Eco Energy Audit

If your living in Ontario and just hearing about this program now your OK you can still participate you just need to act fast visit home eco energy audit to book an audit as soon as possible the auditor will explain everything you need to know.

1. Get your first audit
2. Upgrade your home (furnace, tankless, windows insulation, as much or a little as you choose)
3. Have a second audit preformed to confirm upgrades
4. Wait for rebate money from the Government (usually takes a while, as we all know how fast they work)
   

You Have Had Your First Audit

If you know about the program and have had your first audit completed and maybe a few upgrades on your come installed, you have until the end of the month to get the final audit and receive your grant money.

1. The second audit is cheap and you will receive all your rebates for all upgrades
2. You can go with any auditing company to do the second audit (they all have access to your first audit details and info) Home Eco Energy Audits is a good Toronto based company that has auditors all over Ontario.
   
3. You only have until March 31 to finish this last audit or you lose out.

This is a Win Win program for all Canadian and Ontario citizens, the Government is helping you pay for new HVAC equipment for your home and you never need to pay them back for it.. DEAL

First and most important, de-scaling your tankless water heater.

If the installer was good you will likely have isolation or flush valves installed. These valves allow you to push vinegar or a scale removal agent through the tankless effectively cleaning the buildup off the wall of the inside of the heat exchanger. As we wrote in “Lime Scale The Energy Thief” it really doesn’t take much buildup to decrease efficiency significantly (and isn’t that what you bought the tankless for in the first place?).

The Process

At the Tankless Hot Water Guide were here to help people first and foremost, if you are hand this is something that you can do yourself.  Here are a brief outline of the steps necessary to flush your tankless heater.

1. Unplug your tankless.
2. On the blue isolation (flush) valve shut the Cold water supply off.
3. On the red isolation (flush) valve shut the hot water exit off.
4. Now you will need two short hoses, a bucket and a pump of some sort.
5. Attache the two hoses to the isolation valves (flush valves).
6. Attach the other end of the hose running from the blue isolation valves to your pump.
7. Fill the bucket with your de-scaling agent (vinegar).
8. Turn the pump on and make sure that the red isolation valve hose is running back into the bucket.
9. Let this run for at least 30 minutes.
10. –If the system hasn’t been flushed in a long time and you see a lot of grime, unplug the pump, dump and refill the bucket with new vinegar.  Let run for an additional 30 minutes.
11. After you are finished dump the bucket and fill with clean water, start the pumping again to flush the vinegar out of the system.  If you use a chemical de-scaling solution make sure to rinse your tankless thoroughly.
12. Almost done!
13. Disconnect all the hoses, replace caps, double check everything is back to normal.
14. Turn the two valves back to the on or flow position and plug the tankless back in.
15. Run the hot water at a few taps to push any air in the system out and confirm hot water is being produced.
16. Repeat once every year or so.

3. Advice on Tankless Water

Water naturally contains dissolved minerals such as calcium carbonate, lime, silica, iron, and phosphate to name a few. These trace elements are essential to human health, not so much for your water heater though. With heat the minerals are able to precipitate out and build up on the surfaces.

On day one of a tank type water heater you looking at your greatest efficiency, sometimes as high as 80%. This is reduced quickly as the lime and other particles cling together and bake themselves into a hard crust. This scale builds up on the walls and blocks the heat transfer proportionally as much. With the additional heat not being transferred into the water the steel becomes brittle and can crack quite easily.

Solutions For Lime Scaling

For a tankless water heater it is essential that you have the system flushed once a year with a de scaling solution (vinegar). This maintains the tankless heat exchanger and ensure a consistent efficiency rate. As for your conventional tank water heater, flushing is more difficult but can be done. For the most part they are designed as disposable units that are simply just replaced if broken.
