Hi,
I have a new Vaillant ecotec 28 boiler recently fitted, there is a few issues with it I need advice on, first issue is the pump noise, it seems to be on full speed, heating temperature set on the boiler is max at 75c, the installer left it like that, no explanations of how the darn thing worked or how to adjust any user settings and despite his assurance that the pump noise is normal I was not happy with it, its rather loud compared to my old non condensing boiler, considering its in a cupboard upstairs.
So I did some reading about the boiler temps and have reduced the temperature to 65c, the pumps now pretty quiet thankfully, but I would like to know if reducing the boiler temperature is the correct thing to do to reduce the pump noise ?
Second issue is, originally, many years ago this property had a boiler replaced and I am presuming the flow and return on the original boiler was the reverse of the replacement, so when the new ecotech went in the installer just followed the original layout and the flow and return are still reversed, luckily we have pegler 2 TRV's that I think are bidirectional, so to balance the radiators, I used the lockshield to reduce the flow to some rads and obtained a reasonable balance around the house, not ideal but its what I have, would there be any issues leaving the new boiler flow and return as it is, reversed or would it be better to have it swapped ?
Not using a valliant thermostat, using a ESI wireless one that I fitted myself, trying to work out if its worth while having TPI on or just use optimisation, that's an ongoing experiment
If you got this far, thanks for reading !
