There was a little rubbish, not much really. Chemical cleaner was being used, then flushed through for quite a while.Merry xmas
How clean/ dirty was the water when the pump was taken out?
Hope the consultant can sort it
each manifold has its own pump at the manifold not in the plant room. Manifold picture earlier in the thread.Like I said before isolate manifolds get flow to cylinder hot, so hot u cat touch , leave hot taps running so that cylinder is full of cool water. Turn on say m1 then wait, once return from m1 ok leve it on and turn on m2 keep going until the flow to cylinder cools so u can hold it.
Temps are relative so just wrap a thermometer in a cloth soaked on veg
Oil on pipe. Just enough cloth to hold bulb against pipe . Oil is just to conduct heat as water will evaporate .
Or buy a flexible plastic ones and stick to pipes , the film types.
Each manifold has it's own pump right? - stupid question but needs to be asked?
I think your plant room needs re configured, 100% LLH with pump set to each circ. cylinder fine , get zone valves fitted on each flow in plant room . Ie to each manifold or cylinder. Shouldn't require any disturbance outside of plant room. I would be fitting an additional boiler or boilers tho . My mind u want at least 70kw for peak demand . Won't say this too loud as not a fan of wb but put same boiler in as what u have or fit multiple new boilers say 2 or 3 ideal logic system 30kw or even two kestons as same boiler but higher output avail.
Don't forget to balance system and lag it properly
