Takagi Tankless Condensing Unit
|
The Takagi Flash T-H1 tankless water heater is a new condensing unit available to house hold consumers.
This tankless heater has an average efficiency of 95% with propane as its fuel source and 92% when natural gas is used. In our Canadian climate you can expect about 4 plus gallons per minute in the dead of winter, and much more in the summer when ground water is warmer.
The Flash T-H1 is able to provide about 3 simultaneous showers when ground water is at or below 40 Fahrenheit. This tankless is unique in that it has two heat exchangers which enable the water passing through to absorb much (90 to 97 percent of it) of the heat generated from combustion. The stainless steel secondary heat exchanger has been added to collect waste heat from the units vent stack and divert it to pre-heating the incoming water. This secondary exchanger causes some condensation that is slightly acidic, Takagi has included a collector and a built in neutralizer that allows the drainage to be plumbed into your standard drainpipe.
This tankless water heater employs a variable gas input which allows the unit to produce only the amount of heat necessary to warm the water to a household’s desired temperature. At a maximum this tankless can produce 199,000 BTU’s per hour and in ideal conditions provide 10 gallons of hot water per minute.
There is a downside, the Takagi condensing tankless water heater is quite expensive, but it is one of the higher end units with a very high efficiency rating. Also unless you buy the Takagi temperature controller you are limited to only 4 preset temperatures, 113 F, 122 F, 140 F, and 182 F.
This is a very interesting system but we havent had any direct hands on experience to draw on yet. We should be getting a trial system soon at which point we will provide a new update and evaluation.
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.

Frequently Asked Questions

A Few FAQ
|
Can a home owner install a tankless hot water heater?
We would not recommend a home owner to install their own tankless hot water heater. Tankless water
heaters have strict venting codes that really need to be installed by a professional H.V.A.C company with certified technicians. Most of these units require direct (through the wall) venting with clearance regulations. Unit efficiency can greatly be decreased by insufficient/improper venting. With on demand gas units, gas piping and water pipes may need to be upgraded as well.
Should I buy my tankless hot water heater, then call an installer?
If you decide to purchase a hot water heater from a source other than your installer, you may be faced with warranty issues. Also, all required parts for a full installation, sufficient venting, pipe upgrading and safeties are not usually included when purchasing a unit. Most installers insist on supplying dealer brand units with their installations. This will benefit you, the homeowner, as installers are specifically trained for the brand they install and if required, there will be no warranty issues with parts under manufacturers’ warranty.

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.

Tankless Installation Time
Dec 14th
How Long Will A Tankless Take to Install?
This can be a difficult question to answer as there are a number of factors that need to be taken into account. They range from
- Relocation – Does it make sense to move the tankless closer to hot water demands? does this involve moving the gas lines? Is there a venting issue that requires it moved?
- Size / Mounting - The Tankless is significant smaller then a full sized convential tank, this allows it to be mounted numerous locations.
- Venting – All tankless systems have unique venting requirements this may play a factor in its positioning, get a free evaluation here.
- Type – Do you want a propane, natural gas or electric tankless system? These factors can all play a part in tankless installation times.
The installation crews are scheduled to do 2 tankless installs per day, so most installs rarely go past 4 hours (quite a few have been installed in less than an hour). If you decide to go ahead with the tankless system, be that rental or purchase its a safe bet to allocate 4 hours for the install.
