A thermostatic mixing valve (TMV) is a valve that blends hot water with cold water to ensure constant, safe shower and bath outlet temperatures, preventing scalding. Pressure valves open and close pipes in accordance with water flow.
Why does my hot water keep going hot and cold?
The most common reason for this often occurring issue is a blockage in the hot water heat exchanger located inside the boiler. Most probably because of sludge buildup in the heating system. Unfortunately, sludge buildup is common, especially in installations where the fitter didn’t flush the heating system properly.
Can you regulate water temperature?
Depending upon exactly what kind of faucet you have, different valve-like devices, such as mixer taps, single handle mixers, temperature control valves, and thermostatic mixing valves, are used to regulate the temperature of the water before it comes out of the spigot.
What causes fluctuation in water temperature?
One thing that can cause your water temperature to fluctuate is the source itself, your water heater. Your water heater is a good place to start. Water heaters typically last 12-15 years, so if it is getting on in years, it may be time to replace it. It may simply be in need of some maintenance.Why won't my shower stay a constant temperature?
If your water temperature fluctuates, the pressure-balancing valve might be to blame. Your pressure-balancing valves open and close depending on your water flow in your plumbing system. If cold or hot water levels drop, a broken pressure valve could cause a drop in water pressure.
Why does my thermostatic shower go hot and cold?

How do I adjust the water temperature on my kitchen faucet?
To decrease water temperature, either turn the hot water screw clockwise or turn the cold water screw counterclockwise. Other faucets have either small plastic nubs that you turn by hand or with pliers to adjust the hot/cold mixture or a temperature adjustment ring you rotate clockwise to adjust water temperature.
Does turning up water heater make hot water last longer?
When you raise the water heater temperature, the tempering valve will automatically reduce the volume of hot water in the mix to prevent scalding. Thus, the rate of consumption DOES depend on temperature. The lowered rate WILL make the hot water in the heater “last longer”.
How can I keep my shower water cool in the summer?
Take a quick shower using a low flow shower head say 1 gal/min using the house (hot) cold water to get clean (less volume of water means less heating by the water). Then as a final cooling rinse repeatedly dip a small bowl into the cool water and pour it over yourself.
Why does my hot water stop working sometimes?

Does boiler pressure affect hot water?
The kind of boiler you have can affect the water pressure in both the cold and hot taps. If you have a combi or system boiler, the cold water coming into your house will be at mains pressure. Which is good, it’s usually nice and high. … Low pressure in your hot taps and shower could be caused by your boiler.
How is water intermittent?

Do thermostatic mixing valves go bad?
Older model hot water mixing valves age over time and can break down with usage. As a result they can begin to fail in correctly controlling water temperature.
How do I know if my diverter valve is working?
After you remove the lid of the boiler, you have to locate the diverter valve mechanism. Run tap water on hot and observe the diverter valve. If you run hot water, the valve is supposed to close in order to divert it to the tap, meaning it should move. If you see no movement, then it’s stuck.
