How does a thermostatic mixer work? The thermostatic valve mixes the hot and cold water to your pre-selected temperature and reacts instantly to any changes in the pressure or temperature of the water supply by re-adjusting the mix of hot and cold water.
How does a shower thermostatic valve work?
How does a thermostatic shower work? Thermostatic showers store water at a high temperature before mixing it with cold water in a valve to a temperature that you have pre-set. Along with mixing the water together, the valve will also instantly react to changes in water temperature.
Does thermostatic shower need electricity?
Thermostatic showers rely on the mains water supply to function, so they are not electric. Electric showers are an excellent choice for bathroom and shower rooms as their temperature is not affected by other water use.
Is a thermostatic shower valve worth it?
Advantages of Thermostatic Shower Valves This feature helps make water conservation easy; just turn down the water flow while shampooing or shaving! Some advantages to installing this system are that you get a consistent temperature, Increased energy efficiency, higher flow rates, and possibly a cheaper water bill.
Why do thermostatic shower valves fail?
There are several reasons why the cartridge may have failed; the number one cause is an in-balance in water pressure between the mains cold pressure and the heated hot water(and this is very common). This constant in-balance between the two will cause damage to the cartridge which is housed within the valve.
How long should a thermostatic shower valve last?
On average, the flow cartridge lasts 2 years.
Can you adjust a thermostatic mixing valve?
Yes, thermostatic mixing valves (TMV’s) can be adjusted by removing the central cap. Using a small spanner, turn the valve anticlockwise to increase the temperature and clockwise to decrease it.
Why is my thermostatic shower running cold?
Thermostatic mixer showers: If the temperature of your thermostatic mixer shower keeps fluctuating wildly (getting boiling hot or freezing cold), the thermostatic cartridge probably needs replacing. If the shower works fine without the head attached, then the head is reducing the flow and needs cleaning.
What is the difference between a mixing valve and a thermostatic mixing valve?
A tempering valve is accurate to around 3℃ +/-, while a thermostatic mixing valve can keep the water to 1℃ +/- and responds faster than a tempering valve to changes in incoming water temperature. TMV’s are designed specifically for use in facilities used by high-risk persons such as: aged care centres. hospitals.
Are thermostatic valves necessary?
Thermostatic radiator valves are an excellent way of managing your central heating system and ensuring that radiators come on exactly when needed. TRVs are often recommended as a way to keep your heating costs economical.
Do thermostatic valves need electricity?
Thermostatic showers are not electric as they rely on the mains water supply to function. A combination of water pressure and water temperature is what allows the shower to work. Electric showers have their own heating element, so they use only cold water, whereas thermostatic showers use both hot and cold water.
Do thermostatic valves fail?
The most common problem with a TRV is that the valve sticks or catches. This means that they are either stuck open or closed. If you cannot get the plunger working again, then the valve has failed and will need to be replaced completely.
What happens when a shower cartridge fails?
If the cartridge wears out, your shower valve won’t function properly. (Indicated by leaking or seeping water.) The rubber rings and parts around the shower valve may need to be replaced, as these shower components are susceptible to breaking, corrosion, or dry-rot.
How long do thermostatic radiator valves last?
Ordinary sensor TRVs with wax or oil filled sensor tend to last 10 to 15 years if you are lucky. If you get 20 years you are doing well. Some of the better quality brands did last beyond that, like Danfoss, which was also repairable.
How long do thermostatic valves last?
Your brass mixing valve should last a very, very long time-lifetime (if not damaged). Hard water is more likely to affect cartridge (if you have one) and wears it out earlier than in areas where water is not so hard. I just had to replace my cartridge after only 5 years.
How often should you change your shower valve?

How do you adjust a thermostatic valve?
Locate the adjustment needle on the thermostatic expansion valve. Turn the adjustment needle one quarter turn counterclockwise to decrease the temperature. Each quarter turn is equal to one degree. Turn the adjustment needle a quarter turn clockwise for each degree needed, to increase the temperature.
Can you adjust a shower mixing valve?
Adjust the Shower Valve The mixture of hot water and cold water available in a shower or tub can be adjusted at the shower valve stem, the part found under the faucet. Take off the metal cover beneath the handle, exposing the valve stem. You’ll see a plastic part around the valve stem.
