Expensive, but works

Comments about Taco X-Pump Block, 1/25 HP:

This pump will save you a good bit of space over using separate pumps and the built in heat exchanger is nice for closed loop systems or snow melting. Its very quiet. Its just too darn expensive for what you get. If you purchase a heat exchanger and pump this is still more than double. Other con which isn't a knock to the product at all is most plumbers in my area have no idea how to hook one up or want to read the manual.

DIY Basement Radiant Heat

By radiant

Comments about Taco X-Pump Block, 1/25 HP:

I installed an X Block in combination with a Vertex 96% efficient water heater to heat a 1200 sq ft basement. The heat exchanger in the X Block separates the water source. A slab thermocouple combined with Uponor thermostat sets min/max slab temp. A simple DIY project on new construction. Nice system.

Comments about Taco X-Pump Block, 1/25 HP:

Use as a heat transfer device with lots of built in control options.
Maintains separation from closed loop systems.
Different mode operations for fine tuning system efficiency
Easy to install and set up.

Keep a spare replacement cartridge circulator for back up'

Water quality is an issue

Always use wye-stariners in front of supply to unit.

Comments about Taco X-Pump Block, 1/25 HP:

I have installed 4 of these now and really think they are a great way to use a water heater as a space heating device. I have installed every one with a Toyotomi OM 180. I think they make a great pair as the 180 is more or less a water heater designed to be a hydronic heater. Both the X-Block and 180 are extremely easy to instal. Living in the subarctic, we have extreme temperature swings that can pose a problem for traditional thermal mass heat systems. We can easily have 40-50 degree temperature swings overnight. The outdoor reset mode on this device regulates the hydronic fluid temperature based on the outdoor temps and prevents under or overheating if you have a 4" thick slab of concrete in your house. The thermostat in my house never moves a single degree because the X-Block knows exactly what my Btu requirements are on a "real time" basis. My only complaint would be more thorough instructions on the best settings for your climate. I am sure a professional boiler installer would understand all the settings a little better than me--a builder. Otherwise I, and the folks I have installed them for, love this thing.

Heating System Pump

By Lev, the plumber

from San Francisco, CA

Verified Buyer

Comments about Taco X-Pump Block, 1/25 HP:

i purchased this pump to use in radiant heating systems with floor mounted and wall mounted radiators. Overall is a good product, however, it is hard to release air from the system after installation and prior to filling as there is no blow off valve on the heat source return line on this pump. They have blow off on RMB-1 but not on this one for some reason. I had to buy and install the blow offs. As this pump is already pricey, this additional cost was unnecessary.

    Q:

    Do I need a switching relay in addition to my two zone valves with the Taco X Block?
    Asked on 2/11/2014 by Northwestern Paul from Milwaukee, WI

      A:

      The X-Block takes a single input signal. If you are using end switches with your zone valves, the end switches may be wired in parallel to serve as the input "closure" signal to activate the X-Block. This means that the zone valves will get their power from an external source that runs the thermostats and valve motors for the zone valves. (The X-block is not intended to provide power for thermostats and zone valves, they must be connected to an external power source.) If you are using TACO zone valves there is a TACO Zone valve control that has a 24 volt transformer for powering two wire thermostats and which will provide output for the zone valves and end switch wiring combining this all into a single output for control of a pump and for bringing on a boiler or heat source. In this instance all you would need to use is the dry contact boiler output typically designated by "T T" to signal the X-Block. Check TACO Zone control model # ZVC403-4 at the following link.
      http://www.pexsupply.com/Taco-ZVC403-4-3-Zone-Valve-Control-Module-with-Priority
      This should help with your anticipated installation. The installation diagram with the zone control that is available from this on-line page should help with wiring the control to thermostats, zone valves and for the "T T" contact that will be used to signal the X-Block for operation. (note for start-up, since the X-Block has internal pumps and heat exchangers it is important to assure that the system is well purged of air, so take measures to watch pumps closely on start-up to avoid running them dry / cycle them as needed to clear any air from the system. Programming the X-Block uses Tekmar European program routines, study the manual closely for each step to avoid issues and if necessary contact TACO for assistance if you encounter any problem with setting up the program, particularly if you are using a temperature reset profile to make radiant temperature track outdoor temperature.
      I hope this advise is helpful.

      A:

      The x-block has an end switch which closes a contact that could go directly
      to the boiler control. It probably is going to directly turn on another
      circulator because the x-block has the two circulators built in. But,
      either way, the switch in the x-block should not be used to directly switch
      on a load such as a pump. You need to have a switching relay to power a
      load.

      We had this installed 3 years ago in our home addition for that very purpose. One side manages our radiant floor heating, the other the water for the bathroom. Seems to be working just fine.

      A:

      I have two systems in operation with these units. Domestic hot water heater on the supply side and manifold driven radiant loops on the load. The unit integrates with an on demand water heater well as the source. Most radiant systems require hotter water temperatures than the 122-125 degrees normally used for your domestic hot water, so be sure to add a tempering valve down stream of the system on the domestic hot water supply to the house. You'll need to add a check valve to the return of the xp block to prevent the domestic hot water demand from shorting through the xp block.

      Taco supplies great support. You can find the instructions here:
      http://www.taco-hvac.com/uploads/FileLibrary/102-202.pdf . If you work
      through the instruction sheet it can be easily deduced. Page 11 explains
      the functions and shows the corresponding symbol. The common ones you would
      see is a percentage curve for the mixing pump, signals for supply pump and
      boiler demand. What displays on the LCD depends upon how you have set the
      block- i.e. Set point vs outdour reset. Hope this is helpful. You can
      always contact Taco directly as well.

      A:

      I can answer to a limited extent.  Best advise is to contact TACO directly.  The manual for the X block is very detailed but perhaps unfortunately written by a European Engineer who may presume we know all the "background" information (Tekmar?).  There are many sub-routines to each function and no good "road map" to show a novice the steps to access each function.  I've had great success with the X blocks but do agree that the display and set-ups required more attention to navigating the display than was anticipated.  Some temperature range settings if not used; require scrolling to the upper or lower limit to turn them off and this info is not readily presented in the manual.  If you establish the operation conditions you want the X Block to emulate, sensors that are connected and where they are attached,  and communicate these to tech services at TACO, I trust they will be able to assist with the correct set-up and interpretation of any fault
      codes or "!" that may appear in the display.
