A TMV test is a procedure we use to put the valve (TMV) through to a process to simulate a loss of flow of the one of the water supplies, and also a temperature test. It checks the components of the valve too.

Our controllers can be used simply as an on-demand controller for your recirculation pump or, once configured using either an iPhone, iPad, or Android smart device; it can be configured via timers to keep the recirculation loop hot between specific times of day and on specific days of the week (up to 10 timers can be set).

On-demand recirculating systems can help you save money on your electric bill and water bill, and you also have the added benefit of not having to wait for hot water.

Thermostatic mixing valves must be tested and maintained yearly by a qualified TMV license holder like CRG Plumbing & Maintenance.

This product is simply genius. It revolutionizes the hot water on demand market. Circulating pumps have been sold for years bragging instant hot water and little water waist while waiting for hot water. When we bought this house that had one installed, I was very happy to save water and have instant hot water. That was until I did some research that revealed I am using massive energy by running the pump 24-7 and energy to keep that water hot in the line.  All that waist for the convivence having instant hot water a few times a day. Sure, it did save some water but a very high cost to me and the environment. So, I added a timer to my pump to turn it on morning and evenings when I was more likely to use hot water. Better, but still not that efficient.  I have searched for remote on demand systems that I could add to be more efficient, but they all had issues like hard to install, hard to remember if it was left on or off, WIFI or Bluetooth issues, need to use apps or find a good location(s) for control(s).  Then I ran across this product. Are you kidding me! No fumbling with buttons or apps – just turn the hot water on for a second to get the pump pumping. Brilliant!! Only pumps when you ask for it and need it.  This checks all of the environmental boxes. Absolutely saves water. Use the absolute minimum energy to deliver the hot water – ONLY when needed. The Smart control 32 should be required with every recirculating pump sold.

Best investment I’ve made and hot water on demand. Love it!

Thermostatic mixing valves must be tested by law every 12 months. Not to do so could result in serious consequences for the property owners.

Constantly running hot water can also cause copper pipes to erode. This can lead to pinhole leaks in your pipes, which will then need replacement, as well as cause water damage to your home.

You do not test a thermostatic shower valve, not to be confused with a thermostatic mixing valve. Thus, a mixer shower does not need to be tested, and in fact there are no tests for this type of shower.

Brilliant. Amazing. I installed this unit to replace a wireless remote control.  Sometimes it got the signal, sometimes not. Now there is no doubt. Simply turn on any hot water tap in the house and the pump starts.

To test a TMV valve, we isolate the hot water and then put the valve into a thermo shut down. After, we repeat this process with the cold side whilst recording the temperature of the water.

On-demand hot water recirculating pumps work with one key difference: your water isn’t constantly recirculating, and you save energy and money.

The on-demand controller is contained within the utility closet and activates hot water delivery from any plumbing fixture on-demand and/or with the use of Smart Timers. Owners control the settings of the Smart Recirculation Control units via a smartphone app to ensure your system only runs when you need it.

A Thermostatic Mixing Valve (TMV) is a valve that blends hot water (stored at temperatures high enough to kill bacteria) with cold water to ensure constant, safe outlet temperatures preventing scalding. Commonly found in nursing homes, child care centres and disabled toilet blocks, fitted to showers and hand basins.

When water sits in a pipe, it begins to drop in temperature from heat loss, quickly matching the temperature of the pipes. Therefore, typical recirculation systems constantly run water through the pipes to keep them heated. When the water is recirculated through the system, it doesn’t get a chance to cool down, offering a constant flow of hot water. However, there are some drawbacks to this.

Many cities provide rebates and incentives for installing a recirculating pump because they save water, however, your hot water recirculation system is working nonstop, ultimately driving up your energy bill, so it ends up being a costly luxury.
