Honeywell 3 ports!!!

[gassafe]

What's the crack with Honeywell 3 port valves... I put two together and the whole in the centre of the valve is pretty much the same on both 28 & 22 valves!!! Seems like a scam to me... Why run 28 all the way if there just gonna throttle it down like that!

look into the bottom inlet.

that's where you don't want a restriction

And this is why 2 ports are the way forward.

i seriously wonder why they dont do two ports with unions. would make life so much easier

Because they couldn't be bothered to change the ball size inside no doubt!

Makes a easy swap from other makes so opens up larger market.

Would be even better if all control valves were fitted to pump valves so no draining to replace.

3 port 22 mm will pass 20KW
3 port 28 mm will pass 30KW

2 port 22mm will pass 23KW
2 port 28mm will pass 30 KW

yes all the above came from honeywell tech 2 weeks ago, when I queried it!

*grins*

but with the three port i bet it will only pass 10/15kw each way when both sides are in use !!!

Different from the levels specced in there training manual.

ahhh !!! never knew that

so more like 14kw for heating, 6kw for hot water on a 22mm
21kw for heating and 9kw for hot water on 28 mm

pretty much means a 3 port isn't suitable for a megaflow or oso cylinder then !!!!

Post em up Roger, this was 2 weeks ago when I got through eventully! I queried the guy on Delta t and pump volocity etc, he went quiet, but pulled these figs from his PDF

Nah most MI's insist on 2 port anyhow, Vaillant used to have a 3 port set up with their boiler and unvented though

I was once told the rest or europe and the US use two port only and 3 port are (or were originally) made just for the UK because it's cheaper and consumers in this country always want a cheap job.

I find it believable. I bet northern europe, the US and canada would turn their noses up at a 3 port valve.
