Overview

CALEFFI 252212HP high performance solar-rated tempering valve has BSP 15mm 1/2" male compression threads at all three ends. Australian Watermark Approved and made in Italy. Caleffi identifies high-performance tempering valves with a yellow cap. The Caleffi tempering valve is compatible and direct swap for most mainstream tempering valve brands such as AVG, AW, Reliance, Tomson and Nefa with same functions, fitment and similar physical size.Β 

The CALEFFI 252212HP tempering valve is ideal for high temperature and high performance hot water systems, including solar hot water systems, instantaneous heaters, and pumped ring main distribution systems. It automatically mixes the cold and hot water inputs and outputs a steady 50 deg hot water after mixing. The tempering valve is required in Australia by law in the plumbing rules as it is a safety device. Without mixing, the hot water straight from the hot water services can exceed 70 deg and can cause severe instant burns when in contact with skin. 50 deg feels hot, yet without the dangers of burning. When required, the output temperature of the CALEFFI 252212HP tempering valve can be adjusted between 35-50 deg.

Wobbly but Usable
Color: Grey, Size: Standard - 4 Panel
A bit wobbly, but good enough for the price when you need a solid background for remote work calls.

Nice and easy to assemble
Color: Black, Size: Standard - 4 Panel
I absolutely love this 4-panel room divider! It was super easy to assemble β€” I had it set up in just a few minutes. The material isn’t too see-through, which gives just the right amount of privacy while still letting some light through. It does exactly what I needed it to do and looks so clean and sleek in my space. Perfect balance of style and function β€” highly recommend!

Really adorable & functional room divider! I love mine!
Color: Dark Coffee, Size: 4 Panel
Really beautiful divider. I use it out on my patio at my apartment building to provide privacy, shade & keep my things safe. At 6 foot tall and 4 panels (I strongly suggest 4 panels) it's quite a lovely addition to my home. It's delicate so handle carefully but it comes completely put together & just set it up. Being able to move it inside or outside or wherever because it's so light makes it very mobile. It's not too opaque you can see through it but if it's for total privacy use a tablecloth or something behind it to make it less see through. It's strong and big and I had a question for their cs and they responded immediately and handled it right away which is a sign of a good company. It's light so make sure you secure it if it's windy for stability.
