Example List of Hydronic Parts
1. Taco 0011 Bronze Pump (Circulator) - $297.00
2. Bronze 3/4 inch flange set - $29.75 or $41.27 for shut off flanges
3. Bronze 3/4 inch flow check (Check Valve) - $28.20
4. Circulator Relay - $55.20
Please Note: You should obtain the electric hot water storage tank from a local source as the cost to ship
one of these is generally more than the cost of the tank itself.

How to set up a T-KD20 for use as a Hydronic Radiant Heat Source
Below is a picture of a T-KD20 being used for 2 different temperatures.
We always recommend that you use a direct vent (Sealed Combustion) for your heat source as
this will save you (On average) 15% on your heating bills vs a non-direct heating source.
There are primary and secondary loops and the primary is the loop attached to the T-KD20.
The secondary loops are the high and the low temperature heating loops.
To get one high temperature from the T-KD20 you need to use a primary
loop and then a secondary loop to feed your system.
To get one low temperature from the T-KD20 you use a primary and secondary and wire as below.
There are various methods for wiring but the best method is to shut off
the primary circulator based on the return of the low temperature water
so as to not short cycle the T-KD20.
To get your heat and your domestic hot water from the Takagi you can use many methods.
The best method is to use an indirect water heating tank driven off the high temperature loop.

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 illustrated.
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.)
