Hi guys,
First time here so be gentle.
My System is sealed with a Y plan running 13 rads 10 of which are double panel.
I have recently replaced a standard efficiency warmflow mid-20kw ish oil boiler with a firebird high efficiency 35kw condensing oil boiler. Looking to get better heat and save cash.
Pretty pleased with this, however the flow direction has changed. The old fittings at the boiler matched really well so were not changed ie no pipe work. However, The hot flow now comes out of the boiler at the bottom on what used to be the return. To deal with this it was suggested that i change the direction of the pump which i have done. I have several questions/worries though:
Was it a good idea to change the pump direction?
What negatives could this have?
Im now getting a lot of noise out of my rads, why would this be?
Do i need to move the TRVs onto the flow side of the rads? I doubt they are bi directional as they are pretty old and most of them did not work anyway. Stuck pins etc. Id like them to function so would replace broken ones.
As an aside, Should i get a bigger circulating pump? Over the past few years ive been changing my rads to doubles. 0 to 10 now. My current pump is pretty old and is 5m head
Thanks for any help or suggestions.
Matt
