mixing

In mathematics, mixing is an abstract concept originating from physics: the attempt to describe the irreversible thermodynamic process of mixing in the everyday world: mixing paint, mixing drinks, industrial mixing, etc.
The concept appears in ergodic theory—the study of stochastic processes and measure-preserving dynamical systems. Several different definitions for mixing exist, including strong mixing, weak mixing and topological mixing, with the last not requiring a measure to be defined. Some of the different definitions of mixing can be arranged in a hierarchical order; thus, strong mixing implies weak mixing. Furthermore, weak mixing (and thus also strong mixing) implies ergodicity: that is, every system that is weakly mixing is also ergodic (and so one says that mixing is a "stronger" notion than ergodicity).

    UFH with Capillary Type Mixing Valve

    Do people with this type of mixed flow temperature control have any problems with achieving the required manifold flow temperature? The one below I think is similar to the TIO Mixing unit. In the unit below, the hot (boiler) water enters from the bottom left, red arrow, up through the "mixing...

    Mixing Vertical and Horizontal Combi Flue

    My installation has been classed as Dangerous 'Do not use' by my boiler manufacturer. I have an Ideal Logic 30kw Combi boiler mounted as high as can be on the kitchen wall. Flue exits out through the wall via an elbow but emerges above a flat roof. Unfortunately it's somewhat less than the...

    UFH Thermostatic Mixing Valves

    Are there fundamental differences in some of these TMVs?. The attached one, below, would seem to be the better type where a shuttle moves to balance the hot&cold flows, as it increases one flow it decreases the other to keep the mixed flow constant, necessary say in showers etc. I have seen...

    Adding Thermostatic Mixing Valve

    I have NuHeat UFH system, and this has no Thermostatic Blending valve on the heating circuit. (Heat Master II cylinder has pick up coil) Nu-Heat System installed - This means I can't run store above 60C due to risk of overheating UFH pipes. I want to add a Thermostatic Mixing valve so have...

    URGENT What type of valve is this 3 port valve with mixing valve

    I have a 3 way rough in valve. The first valve has both hot and cold run to it. The second valve controls the shower head and the third valve controls the tub faucet. What is the name of this rough in valve as I’m having a hell of a time finding one. Thanks to all in advance

    How to get thermostatic mixing valve to seal

    I fitted a thermostatic mixing valve under a bath (first time outside of training) but can’t seem to get the larger inner connector to seal. It’s got a rubber gasket that I’ve checked is lined up but am still getting a tiny seep of water when fully tightened. Is it ok to add Jet blue or LSX to...

    Hot/cold taps not mixing

    Hi I have mixer taps on my kitchen/bathroom taps and when I put the hot on a then try to cool it with hot then the hit goes off, what could be causing this?

    Mixing Pressure Problems

    I have a rather large wet UFH system. Water is flowing around the system, but I don't get any (or minimal) hot water injecting from the primary boiler flow into the ufh system. this means the mix temp never gets above 20 degrees. I think that the ufh system's pressure might be too high which is...

    Mixing valve broken?

    Moved in recently and inherited a combi boiler with 2 zones setup, one to the rads all around the house and a second to the underfloor heating in the kitchen. When the kitchen zone is activated, the boiler kicks in, the flow pipe heats as expected and the heat only travels through the pipework...

    Mixing group conflict with Zone valve?

    hi All, can someone help me clarify following issue? is there possibility when room stat calls for heat (UFH system), it opens the zone valve, runs the manifold pump and turns on the boiler but the mixing group does not start mixing the incoming hot water and does not allow the incoming hot...

    Mixing metals on compression fittings

    Annoyingly I have used a copper nut on a steel isolation valve and the corresponding steel nut on a compression copper fitting (15mm). Should I dismantle and redo? I will have to buy a length of plastic pipe and new olives as well as drain system. Or will it be OK?

    Need for Mixing Valve out outlet from the DHW tank

    Hi all, the heating system in a bungalow that uses an Air to Water heat pump has a TMV (thermostatic mixing valve) at the outlet from the DHW tank. It is a gravity system. While the shower is pumped and there is no bath, the TMV is likely to impact on the flow to the WHB and Kitchen sink. Can...

    Hot water/Heating mixing ?

    I’ve noticed that when the wife runs the bath that the central heating gets much hotter than normal when running lately. When she has finished running the bath the heating cools back down to it’s called for setting. Further investigating this with the heating in the off position the heating flow...

    Thermostatic Mixing Valve

    I recently got a thermostatic mixing valve installed. This was put on the flow from from the hot water cylinder so it mixes the hot and cold water for all the hot taps and showers in the house. I have pressurised system. The hot and cold water is pressurised using one pump which is grundfos...

    Mixing solvent weld fittings and pipe?

    do many of you guys often mix the use of solvent fittings. As an example, pipe made by Osma and a fitting by Floplast? Or are they to variant to match up? Cheers

    Faulty UFH mixing valve?

    Please advise, With the UFH mixing valve set to give 45^ Flow temp To the manifold circuit am I right to expect this temperature To remain constant whatever the flow rate, if any, there is to the manifold circuits? Thanks

    UFH mixing valve not restricting heat to floor

    Hi, I've installed a 2 zone kit that uses an RWC mixing valve, Thermomix with hot in, return to boiler and heat out to Ufh pump and return from floor manifold. From underfloor heating store but basically the same as a jug speedfit Ufh kit. I thought I had a duff thermostat inside the reliance...
