    replacing old 22mm 3/4 Rad valves for 15mm?

    thanks that what I thought. Its almost certainly 3/4" imperial pipe as thats what I had when I changed the water tank recently. I'm assuming we can do the same as I did for the water tank and buy 22mm and some imperial olives. - These are what i've found as a possible replacement -...

    replacing old 22mm 3/4 Rad valves for 15mm?

    I've recently bought a house which hasn't been lived in for a few years and as I start to use stuff again it is tending to break/leak. The house is 1960's and has a Copperad Wallstrip in the living room. I can't seem to find much at all about these except some old posters from Back when they...

    Two Switched fused spurs for oil boiler and Hive thermostat.

    Morning, if i didn't just want to stick it all on a 5a fuse could i go ... MCB to DP Switch to an unswitched 3a spur and an unswitched 5a spur? The oil boiler then has its specified 5a fuse and the hive receiver its 3a fuse.

    Two Switched fused spurs for oil boiler and Hive thermostat.

    By the way i'm not arguing that there shouldn't be a single switch to isolate the system but as i have the MCB just above the system which is clearly marked i was wondering if this was acceptable but it sounds like it isnt.

    For your own safety you SHOULD ...but legally not required right? Where as it also says you MUST install it with a 3a fuse and you're saying a 5a will be fine?

    Two Switched fused spurs for oil boiler and Hive thermostat.

    Ok, tbh one makes my life easier and i'll still switch the boiler via a relay so no real chance of more than 3a being drawn through the hive receiver.

    Two Switched fused spurs for oil boiler and Hive thermostat.

    Yes the mcb is right above and feeds both. Surely any competent person would switch this before any work commences or isn't this considered a master switch? Would there not be any liability if i fed the hive receiver with a 5a fuse when it clearly says 3a, in this instance is it not protecting...

    Two Switched fused spurs for oil boiler and Hive thermostat.

    Hi there, I have just moved into a place with an old oil boiler which was using a Sangamo timer to turn on/off the circulation pump but weirdly not the boiler so you had to manually turn the boiler on and off. I picked up a cheap hive which i now have up and running and doing the job pretty...
