Hello everyone
This is my first post on the site but I've spent the last few evenings browsing quite a few other threads.
I recently moved into a house which needs quite a bit of work doing to it. It's substantially bigger than previous properties I've owned and initally I was very confused by the 2 hot water pipes flowing to all of the various sinks etc.
However, I think that I've now got the basics of hot water recirculation and have found the Grundfos Bronze pump in the loft.
I spent last weekend draining down the entire system because there were 10 gate valves in the loft which weren't labelled, and I needed to start putting some isolation valves onto some of the pipes where we're changing sinks.
I don't recall how noisy the pump was before, but there is definitely a hum through the hot water pipes now that the system is refilled and the pump is running continuously.
There is a timer for the bronze pump in the airing cupboard but it's not active at the minute.
We've noticed that the hot water doesn't seem to last very long if the boiler isn't on, and I wonder whether the hot water recirculation system is part of the problem.
So, I'm wondering what the best approach is.
Is the bronze pump designed to be running all the time? It was getting extremely hot and so I've switched it off at the minute.
I could just sort out the bronze pump timer but am not sure how I should set it up in terms of running times
I'm also wondering about putting a honeywell pipe stat (the high temp version rather than a frost stat) on the pipes in the utility room, which is furthest from the boiler.
From what I can see, this is the most effective way to reduce unecessary pumping of the hot water, and therefore wasted heating / electric costs.
However, the timer controls are simplistic and don't allow for different settings at weekends.
Therefore, I wondered if it's possible to use my main electronic 7 day timer to switch the bronze pump at exactly the same times that it switches the boiler for hot water, and thus enabling longer periods of running at weekends
I hope that I haven't completely confused everyone and would really appreciate any advice that is available
Many thanks
Steve
