I have a vailant ecotec 838 plus combi boiler and it has started to make noise. It never used to make noise however recently we have installed two 2 port honeywell motorised valves as we wanted to separate the new wet underfloor heating and the existing radiators in the rest of the house. The noise does not seem to be coming directly from the boiler (put my ear to the casing and no vibration when sound came) it seems that when ever the two port valve for the radiators makes the winding sound when the boiler is on just when the winding sound finishes the sound comes. This happens every 5-10 minutes when the heating is on. The sound is like a bang sort of sound that lasts maybe one second or less. The sound can be heard anywhere in the house as it is quite loud. The sound only happens when the winding sound happens and then stops and then boom.

Also the sound does not happen when the hot water is on so I am thinking it is something to do with this two port valve

Could be a faulty valve.

Part of the reason I try not to fit Honeywell valves these days. I was getting fed up with faulty noisy ones, especially the 3 port valve.

Did you fit an extra auto bypass valve when the 2 x 2 ports were fitted?

Hi,

I do not think my gas safe engineer fitted one of those. How would I know if one was fitted myself? Should I upload a photo of the set up so someone on this forum could tell for me and what would the benefit of this be?

It's always helpful to see a picture

I have two motorised two port valves as there is wet underfloor heating and also radiators in the rest of the house. We use two different thermostats for the two areas. I have recently heard a noise when the central heating is on. I have finally worked at at which point the noise comes.

When the heating reaches the same temperature setting for the thermostat for the radiators the red lights on the RF switch turn off and then you hear the winding sound of the two port valve. Then there is a fairly loud split second bang sort of noise.

I have checked with the underfloor thermostat, and whenever it turns off there is a winding sound on the two port valve but no loud split second sound afterwards.

The noise never comes when the heating is actually on, only when it turns off and the motorised valve then makes the winding sound when the desired temperature is reached. Then the sound comes

I have attached some photos as it might help

As this is probably the same issue as your previous thread I've merged the two threads.

Looks like the valve is round the wrong way to me. Have a look on it for the A and B markings then compare it with the other valve :wink:

Get another gas safe engineer who has experience in this type of work sounds like a valve issue you can bypass using lever and then test
