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
from Macatawa MI
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.
Bottom Line Yes, I would recommend this to a friend

A piece of equipment with many uses
from Santa Cruz, CA
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 efficiencyEasy 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.
These things are great.
from Fairbanks, AK
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
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.

Nice package, easily installed.
By Dr. Heat
from Pittsburgh, PA
I thought the circulators were a little loud.
Merchant response: Most noise issues are caused by bulk air caught in the system components; make sure to take your time and properly bleed the system during installation.
