Heat Exchanger
Navien tankless water heaters utilizes dual stainless steel heat exchangers, providing 3.8 to 4.5 times longer life-expectancy and erosion resistance over the copper heat exchangers used in other tankless brands. Navien’s heat exchangers operate with relatively low water temperature, minimizing damage from hard water conditions and maintains efficiency levels. Its always important to have your tankless flushed once every 2 years or so to remove any buildup from within the heat exchangers.
Efficiency
Because of Naviens high efficiency the tankless can be vented in PVC piping. Basically excess heat is exhausted with all the combustion gasses in conventional tank systems but a Navien uses this to further heat the water. This results in significantly lower exhaust temperatures and allows for the use of PVC exhaust vent piping.

Takagi T-H2S
Nov 14th
The Takagi T-H2S is a new tankless model that Takagi has developed and is now offering. It is available in either Direct Vent or Outdoor models. Takagi’s T-H2S is a condensing tankless that is
very energy efficient (up to 90% EF). The T-H2S was designed for residential applications and is a candidate for the ECOenergy audit rebate program and its $375 tankless rebate program.
The T-H2S Flow
Seeing as the T-H2S is one of Takagi’s greenest tankless models offering an average efficiency of 90% with natural gas and 90% with propane. If you choose this tankless model here in Ontario, Toronto, Barrie, or any of the surrounding cities expect a flow rate of about 4.1 GPM or 246 GPH with an input temperature at 40ºF or less.
Takagi states that the T-H2S tankless can provide at least two showers worth of water simultaneously in addition to one appliance.
Features
The T-H2S can be vented with PVC providing zero clearance for direct vent installations.
PVC venting can be used in all applications and a 3″ exhaust venting option is coming soon.
The TH2S utilizes dual exchangers to maximize the unit’s energy efficiency.
The primary heat exchanger is made of copper while the secondary is stainless steel.
This secondary heat exchanger is used to recover waste heat from the vent stack to preheat
the incoming ground water. This is in fact what classifies the TH2S as a condensing
tankless water heater.

Tankless Purchasing Guide

Guide For Tankless Purchase
|
Did you know that in your home you are probably paying $60.00 or more per month to simply maintain the heat in a conventional tank type heater? How is this possible? Its simple, your regular tank loses its heat up the flue, or out the chimney, then when the water cools it reheats, and send more money and heat out the chimney. This is occurring even while you’re sleeping or at work.
You likely use most of your hot water in the evenings and morning, do you ever run out? Tankless water heaters are able to overcome these problems. A tankless never runs out of water and can have efficiencies in the high 90’s, you will never run out of hot water in your shower with a tankless.
All of the Earths resources are finite and thus as supplies become scarcer prices will continue to increase, minimizing your consumption reduces your bills. A tankless uses energy only when you ask it to provide hot water, a conventional take keeps water hot even when you’re not there, costing you money. Tankless water heaters will save you more money over their lifespan (20 plus years) than it will cost for the new unit. Plus a Tankless water heater takes up limited amounts of space, is easy to clean, and is easily operated.
Tankless Brand and Venting. With all the different brands available to consumers there is a plethora of venting options to vent the various units. Some tankless water heaters can be vented horizontally and others can vent vertically. The majority of tankless water heaters also have computerized safety devices to protect consumers. Most conventional tanks don’t have these advanced safety features.
Applications and Uses. Some applications of tankless water heaters are: boats, mobile homes, RV’s, and radiant heating systems.
Return on investment. The payback period for tankless water heater is between 3 to 7 years, this is dependent on both energy cost and personal use. If you are a high hot water consumer it will speed up the payback process, if you normally use very little hot water then the payback takes a little longer. Remember though, tankless hot water heaters experience zero standby heat loss and this are much more efficient than conventional tanks.
Energy Audits. Currently the Ontario Government has an incentive program that promotes home energy efficiency. It starts with a home energy audit that assesses the current efficiency of your home, after it is completed a report outlining the current state is sent to the home owner. There is an 18 month period for any renovations to take place; once they are completed a follow up audit is preformed to confirm that all retrofits have been accomplished. At this point grants and incentives are sent from the government to the retrofitted home owner to offset some of the costs.Just installing a tankless water heater qualifies you for $500. Check out the Audit page HERE.
Tankless Lifespan. The expected life of a tankless water heater is roughly 20 years. We have customers who still have their tankless water heaters and it has been in service for more than 20 years. A major reason for this is that tankless water heaters are serviceable, unlike conventional (disposable) tank type water heaters.

Tankless Venting
|
There is a plethora of information regarding tankless systems and which is right for you. This can be an intimidating experience for any consumer, today we are going to deal with venting and choosing the right method for your application. There really is no right or wrong choice it’s that some situations will require different methods and we aim to help you choose the option that best suits your needs.
Use the information below to the best of your ability, but if you have a unique situation send us a quick email or give us a call and we would be more than happy to help out.
Tankless systems require oxygen or air to complete and maintain the combustion process. It is essential for tankless water heaters to precisely monitor and control both the incoming and exhaust gases to achieve peak efficiency. As time goes by natural and environmental occurrences build up reducing a tankless heaters ability to efficiently heat water. Different venting systems have different traits let’s look at some of the different characteristics.

Non Direct Vent Indoor (fan assisted)
- Uses a powered fan to push exhaust gases out of the house
- Pulls the air or oxygen needed from the inside of the house
- Fan powered tankless systems allow for increased flexibility in venting (vertical or horizontal)
Direct Vent Indoor (fan assisted)
- Combustion oxygen is taken from outside the home, eliminating thermal drafting issues inside.
- The Tankless water heater is sealed and doesn’t consume any air form the inside of the house.
- Venting is done with two pipes or a single concentric pipe (a pipe inside another pipe).
- Can be used in locations where appliances may be competing for the same oxygen or in cold climates where air leakage reduces home energy efficiency.
- Vertical or horizontal venting
Outdoor
- This is restricted to warm weather climates only as subzero temperatures significantly reduce efficiency and there is a risk of the unit freezing
- Air for combustion is taken directly from the environment around the unit.
- Improves home energy efficiency as excess heat is thrown off outside and reduced A/C load.
