    Ceiling roses with only 2 terminals?

    Thanks for the clarification and the links. I'll order a couple next week to see if they fit. Last question - Regarding a flush box for the wall switch, which is better metal or plastic? I assume plastic is for drywall and metal is for solid wall?

    Ceiling roses with only 2 terminals?

    That's a brilliant idea. Does the earth terminal in the pattress (or a small connector block) have to be connected to anything? What brand is that pattress? I tried to search on Google but could not find it. And what about for the wall switch? I suppose a flush box with earth terminal?

    Ceiling roses with only 2 terminals?

    Thanks guys. I recently purchased an old house (circa 1880) and it's currently undergoing a major refurbishment. I would like to use bakelite electrical accessories as I think modern plastic won't look right in an old house. Here are some pictures. Are these safe? If not, can they be modified...

    Ceiling roses with only 2 terminals?

    Hello, I recently purchased some antique ceiling roses (bakelite material). Inside there's only 2 terminals, so where do I connect the earth cable to?

    Indirect thermal store?

    So, this type of thermal store is an outdated design as it was meant to work with pre-2007 boilers?

    echoes, Does your contraption have a thermostatic mixing valve for combining water coming from the plate heat exchanger with cold water?

    Apparently, continuing supply of calcium carbonate is not good. Read this:

    Indirect thermal store?

    Thanks for the photos. Do you mean from the hot water in the cylinder like Bernard Green's arrangement? What's a bronze pump by the way?

    Indirect thermal store?

    I've been Googling more about thermal stores and saw that the company Thermal Integration Ltd have products like Heatbank Pandora and HIUs. Their brochure says that the Pandora has no need for any discharge pipes. How does this work? And I have never heard of HIUs either so I'm not sure what...

    Indirect thermal store?

    Fantastic. Thanks. How about pipe diameters if you don't mind? Do you know if the cylinder can be located in the cellar?

    Indirect thermal store?

    OK. Does anyone have a complete schematic diagram for that kind of arrangement?

    Indirect thermal store?

    Header tanks have a ball valve, which is the same thing as a cistern or am I missing something?

    Indirect thermal store?

    So, what is the purpose of the cistern if you never change the water in the cylinder? Another question - Can such a thermal store cylinder be located in the cellar? There's a stone table in my cellar and I thought I could use it for an horizontal cylinder like this one...

    Indirect thermal store?

    Thanks for sharing. Would you say that arrangement is the best there is? Better than conventional open-vent? Better than un-vented? Did you mean no hot water in the event of a boiler breakdown? If so, an immersion heater can be installed as back-up. By the way, do you ever change the water in...

    Indirect thermal store?

    See the diagram above. It's fed from the cold water cistern above. But where does the old water in the cylinder drain to? Manually? How often?
