do i really need to get it checked? cuz a plumber can be so prohibitingly expensive! hahah, so hopefully i can figure out the problem, if there's one, from you guys :)

The height is 112cm, diameter 53cm. The label says DD145, probably more than 3years old. Both immersion heaters were replaced 2years ago. I do have a time switch. I was just messing around with the switch yesterday (by rewiring them to 2 light bulbs) and i found out that, in the day, only...

Hi, My boiler is a Heatrae Sadia Megaflo with 2 immersion heaters. The problem is that, I need 2-3hours of boiling time to produce sufficiently hot water. And even then, if I don't use the hot water at all, there'll be nothing left the next day. Please help.

oh dear, I can't find any other prospective valves. The one that i was twisting has a label of "set temp 90-95, set pressure 10bar, discharge 10kW, date". Other valves include a 3bar (which i can't budge), and a 8bar. am i twisting the wrong valve?

well, I do know i'm on econom7...does that have anything to do with these phases thing? THen again, kai was talking about the live, neutral, earth thingy. I mean, it can't be that hard to just unwire the switch and rewire them into a socket, can it? without causing some major explosion? a job...

ah, the big sticker. I'm sure i've followed that step before. it uses the term "overflow" instead of tundish!? anyway, I carried out the instruction, and halfway through it, it says "hold temp/pressure relief valve until gurgling stops and water stops running from valve and tap". This time...

wow...in that case, I better stay off the switches then. although i could really really use the extra potential sockets.... too bad. but thanks ppl!!!

Running off the hot water? Do i need to run the water until there's no hot water left, before opening the cold water again? And dont' attempt it? why not? which valve if i get wrong will cause disaster in the cylinder?

haha, so the tundish thing. I haven't actually felt the water directly. But i've felt the pipe that was leading to the tundish. It was hot when dripping. And the one time when i try feeling again after it's stopped dripping, it was COLD.

I don't understand the "different phases" part. What if I unwire both switches? Surely that would completely isolate the heater from ANY electricity...no chance of simply plugging the heater in... I mean, I don't think I need the heater... ,. although will it be dangerous while I'm unwiring...

well, I don't know what a uhw cylinders are, but let me try showing what i meant in this picture. www.gasapplianceguide.co.uk/Systemfit_03_1.jpg If I can just pinpoint it right, I'm saying the "diamond shaped, black thing, connected on one end, on the right of the picture" leaks. Now, i don't...

Hi, My boiler is a Heatrae Sadia Megaflow. The problem is, the valve leaks if I leave the boiler on for 2hours. It will keep on leaking until all the hot water's gone! However, no problem if I on the boiler for just 1hour. i dunno if there's enough details, but please help. :)

does that mean as long as I remove both plugs, it's gonna be safe?

i don't really know how a storage heater works. My current rudimental understanding is that, if I switch on the offpeak switch, the heat storing begins. And if I just leave it there, the stored heat will be released in the daytime. But one question, can you control the way heat is released in...

Hi there, crap..I don't know how to insert images! So basically, my heater has two switches on the wall. Not the 3pin plug or anything. Just on/off switches. So i'm thinking of changing one of them into a socket for a 3pin plug. Am I getting these terms correctly here? is it ok?

Hi there, I'm just wondering why my panel heater uses two plugs. And if one of them is redundant, can I rewire it to become a 3pin socket? Please advise. thanks
