High Volume Indirect Water Heating for Residential & Commercial Applications |
|
|
The Takagi T-K1S Tankless Water Heater can be used as an indirect water heater in
conjunction with a storage tank for high volume situations. The Storage tank should be 30 gallons or larger and
must always be set at least 5 degrees below the T-K1S. The T-K1S is factory set at 122° so if
you want to raise your tank temperature to 122° - you will have to purchase the T-K1S
Temperature Remote Control or set the internal dip switches of the T-K1S.
The standby losses that are associated with typical gas water heaters are eliminated because there is no flue dumping the stored heat out of the storage tank. Recovery time can be over 5 to 6 times faster than a typical gas water heater due to the high recovery rate of the Takagi T-K1S. Efficiency is also maintained over time, which is not the case with a storage tank water heater. You should use a typical electric tank water heater for the storage tank - you disconnect the heating elements and use the lower aquastat to activate the circulator relay to turn the circulator so when the tank's aquastat calls for hot water - it activates the circulator that will pump water from the tank to the Takagi T-K1S tankless water heater and then back to the tank. You can use different size tanks to accommodate up to 5 bathrooms or more. For those of you using multi-shower heads - this is an excellent and efficient way to use multi-shower heads and still get the efficiency of a tankless water heater. To use the T-K1S as a heat source for your heating system - you can heat your Radiant Floors, Hydronic Baseboards and Air Handlers with the T-K1S. Just continue down the page to locate the info. HouseNeeds Inc. sells all the components needed for these systems. |

A Storage Tank (Indirect or Stand-Alone) for use as a Hydronic Radiant Heat Source
We do not recommend open loop heating systems as they can be dangerous and more and more local codes are not allowing them. So be careful if you decide to use an open loop heating system. For a few extra dollars you can add a flat plate heat exchanger to the system and get a good heat system and a safe potable water system with one heat source. The example below illustrates this. You may not need all the components shown. In the picture below we show a tank but this could be any heat source that you want to isolate from the heating system. For example, a wood or gas boiler. (If you use non-oxygen barrier PEX with a boiler then you would need to use something like this.) |
