What about Valve-ware manufacturers then?..

[Batpig]

Okay, okay...

In my quest so far to find an environmentally-friendlier (but still practical) alternative to my current electric storage HWS, I've struck out on a few things so far, include my most recent thread to find a fully-automatic on-demand hot-water-recirculator...

But that's okay, because I reckon that I can come up with my own system anyway. I'm just going to need a few bits and pieces, the most specialised of which will be a particular type of purely mechanical (rather than electronic) thermal-expansion valve - along the lines of a PTR, but different. For the auto-minded among you, think along the lines of a thermostat in a car, but not the fully opening and closing ones, but rather the other type that always maintains a certain amount of bypass.

I've had a look through the Reliance website, and there's nothing (as far as I can see, at any rate) that's remotely akin to what I'm looking for.

So, does anyone know of any other manufacturers of thermally-triggered Valve-ware apart from Reliance?

(I'm also going to need an in-line Flow-Sensor. Would be great if you knew who did these too...)

Thanks Again,
Batpig.

This enviro-flow thingy comes in two versions.

The first one is for use with a basin set. You tap into the T between the tap and the spout. It's a two way valve that switches between two outlets when the temperature changes. When the water is cold, it is open to the divert side. When the temp rises above the preset, it closes the divert side and opens the line out side. So when you turn on hot tap, the cold water diverts until it gets hot enough to switch the valve.

The second one is a combination thermo and pressure valve. When the water is cold and the valve detects a drop in pressure, it opens the divert side. Cold water runs until it gets to the factory preset temp, then the valve opens to the main line side. When you turn off the tap, the pressure increases and that closes the pressure valve.

Both valves are passive.

You are a Champion, Silent. You are the Ponsford of the "Know Bloke Stuff" world. A real quiet (or in your case - Silent...) achiever...

For Inline flow sensors google IFM-efector.
I've used their sensors for years and they are excellent.

Good One NC.
