Ämne: Växelventil

[Trau]

Hej,

Jag bor i Finland och har Carrier 30 NQ C9NH värmepump. (~IVT modell Greenline Plus C9). Maskin är 12- 13 år gammal.

I am now thinking to install magnetfilter to the system. I need to hire professional anyways.
I have read that there have been lot of problems with the three-way valve. I am now wondering that should I change the three way valve at the same time.

My three-way valve is LK Armatur model. It seems to work OK.

1) How long is this LK Armatur model working OK normally? Have you had problems with this type?

2) How can I test that is this three-way valve leaking?
I have husdata.

 ( The system has separate 100 l buffer for floor heating, two separate floor-heating circuits and shunt-valve. The radiator-out temperature is measured after shuntvalve so I have understood that also shunt-valve position affects to radiator-out temperature .)

The LK three way valve is the best option, it usually works good.
If you got problems with this you will notice that it will either not produce heat to the house or no hot water.
