Instant or Tankless Water Heaters?
Apr 29th
Things to Know.
|
Most of us have grown up with a standard tank type water heater. As such we are used to the way our hot water system works. Switching to a tankless water heater will have an affect on the way your hot water system works.
With a tank type heater, when you turn on a hot water faucet, the hot water, typically 140 degrees, immediately begins flowing through the pipe to get to your faucet. As the water travels through the cold pi pe, it cools off until the piping material warms up. That is why your hot water doesn’t instantly go from cold to hot; it has to warm up the pipes first.
Some homes have hot water circulating systems that circulate the hot water through the pipes to obtain instant hot water at every sink. Circulating systems can save a lot of water. They are wasteful of energy though, since the water heater will fire up more often to replace the heat being lost through the piping which acts like a big radiator even if the pipes are well insulated.
There are also pumping systems that pump the hot water to the fixture from the heater only when you want to use hot water and you don’t run any water down the drain. You still save the water and time, but you don’t waste water.
Tankless Systems
Tankless water heaters are being promoted as providing endless hot water and as being energy saving over traditional water heaters. While both of these facts are true, there are other things to consider.
If you are considering replacing your tank type water heater with a tankless unit, and you have a typical house, make sure you get one large enough to do the job. Since you are heating water as you use it, you must heat it much more quickly than a tank type heater so you need to add heat much more quickly.
For a gas type heater this means you will be using a lot more gas volume/ minute than with a tank type heater. Your exhaust flue may need to be larger and the gas line might need to be upgraded. For electric units you might have to have special wiring put in to handle the high amperage loads created by an electric tankless water heater.
Tankless water heaters are typically much smaller than conventional tanks and are hung on the wall, resulting in a significant space savings.
Tankless water heaters can save you a modest amount of energy, typically around $20.00 – $40.00 a month. They are also eligible for home energy Grants and Rebates provided by the Government to aid in a speedy transition from the old energy consuming conventional tank to this new efficient technology.
Takagi T-K3 – $1495.00

T-K3 – $1495.00
|
The T-K3 model, also known as the “Revolutionary T-K3,” is one of Takagi’s most versatile and powerful residential units. The T-K3 offers Easy-Link capability, which allows you to connect up to four units without the use of a controller unit. The T-K3 can also be converted to a direct vent model.
Compact Size:
Only 13.8 inches wide, the T-K3 can be recessed between wall studs for even more space savings! A special recess box is available for outdoor installations.
Lower Activating Flow Rate:
The T-K3 activates at only 0.5 GPM, which allows the use of smaller water flows in bathroom sinks and showers. This reduces water waste and allows for stable temperatures.
Parallel Installation:
Using Takagi’s Easy Link technology, the T-K3 can be installed in parallel with up to three other units without the use of an additional control box, generating more flow while saving money, space and installation time. Four T-K3 unites will deliver a total of 21.6 GPM at 60 degrees F delta T; or 26 GPM at a 50 degree F delta T.
Direct-Vent Conversion:
The T-K3 can be easily converted into a direct vent model for inside installations that need to import combustion air from outside.
Eight Temperature Settings:
Instead of the usual four settings, the T-K3 offers eight separate temperatures, set by dip-switch: 104 degree F, 113 degree F, 122 degree F, 131 degree F, 140 degree F, 158 degree F, 176 degree F, and 185 degree F. This versatility reduces the need for a separate remote control. However, setting temperatures other than the eight presets requires the TM-RE10 temperature controller.
Longer vent runs:
The T-K3 can have a vent pipe run up to 50 feet with five elbows, instead of the normal 35 with three elbows.
As you can see, the T-K3 incorporates all those “why-don’t-you-have-this?” features into this one new product. Its larger flow capacity through parallel connections will meet the hot-water needs of most high-volume residential applications and many commercial projects, too. In short, the T-K3 fills the gap between the single residential heater and multiple commercial T-M1 units. Performance depends on the temperature of the ground water of course: At a delta T of 60 degrees F in warmer areas – for example, where the winter ground water is 60 degrees F and with the output set at 122 degrees F – the T-K3 will provide a 5.4 GPM, or 324 GPH. In colder areas where the input temperature may be 40 degrees F or less, expect a flow rate about 4.1 GPM, or 246 GPH.

Tankless Systems Save Space

Tankless Systems Save Space |
Most residential water heaters are located or installed in areas such as a utility room,basement , closet or garage. Storage tank water heaters be it electric or gas require a substantial amount of space, space that could be used for other purposes such a additional storage place etc. If you decide to go with a tankless water heater you will save space and money!
Tankless or instant hot water heaters have no storage tank, they heat the water as it is passing through the appliance, thereby giving you a potential savings of 60%. That is a significant reduction on your water heating bills compared to a storage tank water heater not to mention the space savings due to its’ compact size.
