Tankless And Water Heater Servicing In Toronto

Water heaters

If you own a tankless it is important to service your system.  A tankless is designed by engineers to have, first and foremost, the heat exchanger and internals scrubbed with a mild acid (vinegar).  The vinegar reacts with a buildup that occurs in all pipes and watercourses (scale and lime deposits) effectively eating it away and clearing the heat exchangers and pipes. This scale acts as an insulator significantly reducing the transfer of heat to water. Engineers have also taken many precautions to ensure that internals and parts of a tankless have as few wear points as possible.  This has increased the lifespan of a tankless water heater to over 20 years!

Direct Energy and several other large companies that rent water heaters are trying to reduce the tankless emergence.  Currently if you’re renting a conventional water heater the system is designed to have a lifespan of around 10 to 12 years.  After this point the water heater will have significant buildup inside severely reducing its efficiency.  The thing is that none of these companies will push you to replace your system since you are the one paying the gas bill and it only affects your homes energy consumption.

What Can You Do?

That’s easy, call the company your renting your water heater from.  They will tell you the buyout costs and the age of the water heater you have.  If the system isn’t very old I would recommend you keep the water heater until it reaches its operational lifespan (10-12 years). If your system is already quite old you may simply need to schedule a removal with your water heater rental company. Then start getting quotes for a tankless system.

Once that new tankless is installed make sure you take care of it, have it flushed once every two years at the minimum (or flush it yourself).  A flush is simple preventative maintenance that will ensure your system makes it past the expected 20 year lifespan while maintaining its 98% efficiency rating!

Prevent Deadly Diseases

Prevent Deadly Water Heater Diseases

Legionnaires’ Disease can be fatal and the standing hot water in a conventional water tank creates an ideal environment for it to thrive and reproduce. A tankless water heater has no standing water eliminating the threat posed by the deadly disease. Don’t take chances with your family’s health, install a tankless system and ensure they’re safe.

If you read a checklist of energy-saving tips its very likely to includes a recommendation to turn the temperature of your water heater down from 140°F (60°C) to 120°F(49°C), including these popular websites — TreeHugger and Planet Green — Yet when seeking an opinion from industry professionals they will tell you never to set your heater below 140F, as it can become a sort of petri dish for Legionnaires Disease.

Legionella pneumophila (Legionnaires Disease) is an aquatic organism that thrives in warm environments. The disease was first identified in Philadelphia in 1976 after 34 veterans died attending an American Legion Convention.

The important thing to know is that the bacteria that causes Legionnaires Disease are very temperature sensitive.

  • 70 to 80 °C (158 to 176 °F): Disinfection range
  • At 66 °C (151 °F): Legionellae die within 2 minutes
  • At 60 °C (140 °F): Legionellae die within 32 minutes
  • At 55 °C (131 °F): Legionellae die within 5 to 6 hours
  • Above 50 °C (122 °F): They can survive but do not multiply
  • 35 to 46 °C (95 to 115 °F): Ideal growth range
  • 20 to 50 °C (68 to 122 °F): Legionellae growth range
  • Below 20 °C (68 °F): Legionellae can survive but are dormant

Hydro Quebec has found that even at 60 °C – the setting on most electric water heaters – an estimated 25% of all water heaters are contaminated by legionella bacteria in Canada.  This is a staggering statistic. But why are more people not contracting the disease?  Well it can simply be left to chance, the bacteria most often enter the lungs due to aspiration (aspiration means choking such that secretions in the mouth bypass the choking reflexes and enter the lung) and thus drinking contaminated water is not a major cause of Legionnaire’s disease.

A conventional tank draws hot water from the top and adds cold water to the bottom providing a continuous reservoir for this disease.  When cold water is injected it lowers the temperature making it idea for the bacteria to multiply.  A tankless is a different system all together, tankless water heaters have no standing water and this no place for the bacteria to take refuge.  In addition a tankless system completely flushes itself every time the hot water is used in your house maintaining a clean bacteria free environment.

Legionnaires Disease can be deadly and affects both children and elderly more so than others, a tankless water heater is a great solution for this problem.

Ontario Water Hardness Levels

An instant hot or tankless water heater is extremely efficient.  The system relies on its advanced heat exchanger to quickly heat up water.  Scale and Lime tend to build up faster when water is heated, so to combat this problem a tankless is usually installed with flush valves, which allow vinegar to be pushed through the system dissolving the build up and returning the tankless to its original efficiency level.  This build up is exponentially increased as the grains or water hardness increases in communities and towns throughout Ontario.

Hard Water Causes Inefficiency

Below is an extensive list of Ontario cities and the corresponding water hardness that is present in the water supply.  The higher the number of grains the harder your water is, which, in turn produces more scale and deposits in your water heater, on shower heads, around faucets, and so forth.  A conventional water heater will become much less efficient with time in a hard water situation, and it can’t be cleaned. For this reason we recommend a tankless system that can be cleaned with a vinegar solution, restoring efficiency.

Quick Hard Water Exercise:

  1. Lookup your city and see if you have hard water
  2. Think about how old that 40 gallon hot water tank is in your house
  3. Know that in on average at 7.5 grains of hard water a regular tank loses 2% efficiency a year to due scale build up
  4. That 2% doubles to 4% at 15 grains and so on…..
  5. After you do the math a tankless that is able to be cleaned of all scale becomes very economical

It’s always a good idea to have your water tested to determine not only water quality but water hardness and this list should be considered just a rough guide.

Tankless Scale and Lime Buildup

That crusty buildup on your faucets, shower heads, and dishwasher is lime scale buildup.  It forms when water passes through your fixtures, and reduces the functionality and efficiency of your household appliances. Conventional water heaters have been known to accumulate as much as 20 lbs of scale buildup over their lifetime. With the application of heat, scale buildup occurs more readily, accelerating the process and causing more problems.  A conventional water heater loses more than 2% efficiency per year because of this buildup, which acts as an insulator preventing proper heat exchange. A tankless water heater is just as susceptible, but a simple built-in system allows the buildup to be removed, returning the water heater to its original efficiency.

We offer tankless cleanings and recommend you have your system flushed once a year to maintain its highest efficiency.  This is a relatively quick process taking about an hour to complete.  In addition to a flush, we inspect the system’s igniter, flame sensor, fan, and venting system to ensure everything is in tip top shape.
