If you’re searching for an endless supply of hot water for your home or business, Rinnai tankless water heaters offer you hot water on demand, 
so you are not stuck with a fixed and pre-heated supply. You can enjoy hot water when you want it and for as long as you want it, so go ahead and do the dishes, run the washing machine and take a long and luxurious bath at the same time. No more worrying about running out of hot water with a Rinnai tankless water heater.
As a Rinnai tankless owner you will enjoy up to 40% energy savings. These units are highly efficient and only heat the water when it is needed. When the demand ceases, the unit shuts down and uses zero energy-a revolutionary advantage over the big and bulky inefficient conventional tanks heaters.
Purchasing a Rinnai tankless water heater, gets you will a reliable and durable copper heat exchanger with a typical life span of 20 or more years (that is twice as long as the old tank water heater’s life span). In addition, the traditional tank water heat accumulates a buildup of rust and sediments that collect in the tank-where the water you drink and bathe is stored. With the Rinnai tankless heaters, no water is stored, so you only get fresh and clean hot water because the water is heated as it passes through the unit.
Being about the size of a small suitcase, the Rinnai tankless unit can be installed on virtually any wall on the inside or outside of your home. Rinnai offers you a line of controllers that makes it very easy to set the hot water temperatures for multiple locations in your house.

Takagi Tankless Condensing Unit

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.
