Tankless Hot Water Heaters, Efficient, Effective, Endless.
General Info
Grant Money Increased By 25%
Apr 1st
25% more for a new Tankless
|
Part of the government’s economic action plan is to boost the eco energy retrofit program that is currently running. The government has increased all available grant money for energy efficient retrofits by 25%. Additionally the program has been expanded with a 300 million dollar increase in funding over the next two 
years.

Initially the program gave home owners 18 months to complete all retrofits, perform the E audit and submit files for rebates. This has now been extended and homeowners that are past their 18 month time frame can still perform retrofits and get access to additionally grant money by performing a F-audit.
This is really significant for The Tankless Hot Water Guide as the additionally grant money will further reduce the cost of tankless water heaters for consumers. A tankless with an efficiency of .82% or better will get you 630$ in rebate money. If you decide to go with a condensing tankless water heater the grant money is even better (.94% efficiency or better) this will net you a 750$ cheque from the government.
You cant find a better time to get go out and get a tankless water heater.
Condensing verses Non-Condensing Tankless

Condensing verses Non-Condensing
|
Tankless water heaters come in two different efficiency styles, condensing and non condensing. A condensing unit will recover more than 85% of the gas that a regular tankless water heater would otherwise vent out. Navien or “Navian” makes a tankless system that is 98% efficient by employing the condensing system. The high efficiency is gained by allowing the relatively warm exhaust gases to transfer otherwise wasted heat to the incoming water preheating it before flowing through the primary heat exchanger. This adds about a 10 to 15 percent efficiency increase to a tankless water heater which in itself is already quite efficient.
Now the grants that are available from the provincial and federal government are 
different for a condensing and non condensing tankless water heater. A condensing unit will receive $600 in total grants or $300 from each government level. The non condensing unit will net you $250 from provincial and federal netting $500 total. The governments trying to reduce energy consumption and pollution emissions would naturally give more grant money to tankless water heaters that are the most efficient.

Tankless Government Grants
|
Currently the Ontario and Canadian government are giving rebates to households in Ontario that upgrade 
their conventional water heaters to either a state or a tankless water heater (I realize that state tanks have not really been explained so I will make a point to do a synopsis on them this week). The provincial (Ontario) will give 250$ for any tankless water heater that is installed, the federal government will match that offer which totals the rebate to 500$. This is a good chunk off the purchase and installation of a tankless water heater. State tanks are eligible for 300$ from the federal government and another 300$ from the Ontario government totaling 600$.
Additionally if you live in the Enbridge territory they are offering 300$ off your gas bill for any new tankless 
water heater installation in your home. Enbridge’s territory consist of most of southern Ontario. Their service territory includes these cities referenced below and a number of others but it would be too long to list:
- Barrie
- Bolton
- Brampton
- Caledon
- Metro Toronto
- Mississauga
- Newmarket
- Richmond Hill
- Whitby
Ontario has a unique market where a significant portion of hot water tanks are rented. As the market for tankless hot water tanks begins to penetrate households there has become a 
strong demand for rental units for these systems as well. If you decide that renting is a better idea than outright purchasing you are still entitled to the rebates that are offered from both the government and from Enbridge.
There is a small catch though; to prove that you have upgraded you water heating system the Ontario government requires that a homeowner get an energy audit. This is a thorough evaluation of your home and its overall efficiency. Once the first audit is completed, you, the homeowner are sent the results of your audit (SAMPLE REPORT). Now that this is completed you have 18 months to make any renovations, or get your tankless hot water tank installed. After the renovations have been completed you need to get a second audit which will validate that all upgrades have been completed and grant cheques will be sent. Looking for an audit? we can put you in touch with a certified eco energy evaluation company. FIND OUT MORE
This is a bit of a complicated process but if you are looking to upgrade even a few things there are rebates from the Ontario government for almost anything that will make your home more energy efficient.

- If you decide to Go tankless you can expect savings of up to 30-50% on your water heating costs.
– For every dollar of gas spent on heating water with a tank, 30 to 50 cents goes straight out the chimney. Tankless units are so efficient they ultimately pay for themselves through the energy savings they generate each month.
- Because water is heated on demand with a tankless water heater, you will never run out of hot water and the water temperature will always remains constant. You can take a shower, run the dish washer and use a tap at the same time with no interruption of water pressure or temperature. One of the best improvements is that family members can take showers one after another and you will never run out of hot water.
- Tankless systems last twice as long as typical conventional take type storage systems – about 20 years. And, unlike typical water storage tanks, tankless water heaters never rust, accumulate sediment, leak or flood your basement. Additionally, they are much safer because there is no active pilot light.
- Tankless water heaters reduce nitrous oxide (major smog producing gas) emissions by up to 80%. When you switch to a tankless water heater, you eliminate up to 1,000 pounds of polluting carbon dioxide emissions from the atmosphere every year!
Recirculation Tankless Installations

Tankless And Recirculation
|
Some Larger homes may require a recirculation loop so that hot water gets to the desired applications faster. They are commonly used with conventional tanks but certain tankless brands can also be used to fit the bill.
What is a ReCirculation Loop?
The loop usually runs the length of one side of the house and then back along the other side. It should be well insulated and have a continuous flow so that there is always hot water in the loop. This way when someone needs hot water at a shower on the other side of the house it only takes a few seconds for hot water to reach the user. If there wasn’t this recirculation loop the water would need to flow all the way from the other side of the house, this could take few minutes and waste gallons of water.
See the diagram below for a good example
Tankless Recirculation
There is not a lot of tankless water heaters that can suitable provide the demands of a recirculation loop. In fact some companies will cut the tankless warranty in half if it is used in a situation where a recirculation loop exists. There are others that don’t modify the warranty and depending on installation Rinnai is one of the brands that allows for a recirculation system. Make sure to talk to your plumber or contractor before begining as they’re a lot of factors to consider before installation.
Solar and a Tankless

Solar And A Tankless Heater
|
There is starting to become a buzz around solar hot water systems. If you have a good, knowledgeable contractor a solar water system can work quite well with a tankless hot water heater. 
Here are a few of the advantages that you can expect when combining the two systems.
1. The preheated water coming from the solar water heating system will increase the flow of hot water out of a tankless unit. The reason is due to the fact the tankless has to heat pre-warmed water reducing the necessary temperature rise. The amount of hot water a tankless can provide depends on the input temperature. The greater the temperature rise necessary the slower the water can travel through the heat exchanger and the slower the output flow. Incoming water at 45F vs. 70F vs. 100F will have very different results on the output of a tankless system.
2. The water is already warm or even hot from the solar rays before entering the tankless unit and therefore the added wait time associated with a tankless unit can be reduced or even eliminated.
3. Its important when combining a tankless and solar water heater to consider a tankless unit that recognizes incoming temperature as well as outgoing and is able to fully modulate its burner (therefore only burning the necessary amount of gas to raise the temperature to the appropriate amount).
4. With the right tankless unit and an appropriately sized solar system you may find that your tankless rarely need to run. In fact some people have found that their gas bills are now costing only a few dollars as opposed to a few hundred dollars.
These Solar systems can be a little tricky in Ontario and Toronto as we have winter and the solar system (if it fails) could experience freezing. This would rupture the thermal cells in the collector rendering it ineffective. It may be necessary to use a glycol system to prevent freezing if electricity goes out. Your contractor should be able to provide all necessary info, or fill out the contact form and we can help.
