A circulating library (also known as lending libraries and rental libraries) lent books to subscribers, and was first and foremost a business venture. The intention was to profit from lending books to the public for a fee.

Hi, I'm new to this forum so I hope I've posted this in the right place. I installed a Grundfos UPS2 15-50/60 (part number 98334549) circulating pump into my oil fired central heating system 4 years ago. Recently on the boiler firing up the pump has not started, there is an intermittent...
Clearly if not hot enough the house will not get warm enough. However had some problems with my oil water heater for central heating and domestic hot water not lighting, the engineer came and adjusted electrodes, and now seems OK, but at same time he turned up the temperature of the water a bit...
I have recently had a new boiler and circulating pump installed keeping the hot water cylinder. I have the hot water timer set to come on for an hour each morning but when the time is reached, a loud bang comes from the pump which can be heard all over the house. Can anyone please suggest what...

I need to replace a broken circulating pump, Grundfos UP20-BXUT. I'm struggling to find one (I live in France) and wonder if there's another make that would fit into the existing plumbing?
Alternatively, as it's the motor / pump rotor that seems to be sticking, could I buy a basic Grundfos...
Two years ago, I requested a fully qualified plumber to change the location of the hot water cylinder in a vented central heating system. I wanted to move it from the first floor to the loft, which he did. During the last two years, I have often noticed when I have been up in the loft that the...

This monster pushes water around the heating coil of s 210 litre unvented cylinder. That's all
It used to be 2 cylinders, and will be again at some point (I have questions about that too but I'll create a new thread)
My question is - does anyone...
Hi,
A new customer has contacted me stating a plumber fitted a new radiator for them recently and a few isolation valves and now their heating isn't working.
I went out to view and couldn't see anything obvious other than the pump not circulating past its top valve. The only other thing is...
Hi,
I am asking here because I have seen a range of answers to questions about pump settings, and some YouTube videos that do not seem right to me even though made by paid plumbers (I won't use the word 'professional' as I reserve this title to those who are trained, qualified and use their...
Hi guys, I’m in the process of ripping out an old one pipe system and replacing it with a two pipe, feed and return. The new system will be on two zoning valves one for upstairs and one for downstairs.
Originally i wanted the system on a single stat and single zone valve... with a flow of 0.477...

I live in a large draughty old house with a 5 year old heating system which was installed from scratch (new rads, pipes, boilers, etc. nothing old left in the system).
The plumber's no longer in business.
The system has two 35kW system boilers connected through a low loss header and then has a...
Hi I am thinking of modifying the pipework to my Baxi 24 solo he. At the moment the feed and return both point upwards. I intend to feed the return from the bottom, so I will need a vent on the return, any suggestions of the best way to go about it. I am thinking of removing the supplied return...
I have a problem that try as I might I can't solve. It all started when I changed a rumbling UPS for a new UPS2 pump. After 40 minutes I can hear some gurgles of air / gas entering two radiators. This carries on for a few minutes and then stops. I bleed this off and the same thing happens the...
Do you like the new smart circulating pumps or prefer the standard circulating pumps, plumging suppliers in northern Ireland report they have alot of returns of faulty smart pumps.
Hi there,
I think my pump is on its way out and want to replace it before winter hits.
It is not a recognised brand or model number so I am struggling to understand the type of pump I need to buy for a like for like replacement. There are some numbers in a table on the head but I don't know...
