Naaah, probably the handset was too big and wouldn't fit between their legs when they were trying to wash their arse crack. ?

I don't usually bother as they have an adverse affect in the winter. Their the crudest of stats and I haven't fitted one for prob over a decade, other than in rentals where the Tennant only understands noises.

You said you opened it and checked Should have gone to Specsavers?

Water would have come out as they're wet tested by QC At least you can wash ?

Not really good enough for PH or UFH afaic. Wiring doesn't affect the hysteresis, it just makes it work

And the symptom of crap room stat with huge hysteresis giving over and under shoot of the stat set point.

I could always take them hostage, then you could sneak in and repair it in stealth mode. ?

Good girl ?

Should be a relatively easy fix though.

Yup. I wonder how long the chrome plated plastic will last ?

If the room is toasty at 5am then the flap is not shutting or the boost is not set to minimum. No, it would have wasted all the heat instead of storing it, and then left you with nothing to use during the day.

A pic of what you've got I meant

Get the screwfix one, I can't wait that long

Q1 Do you have two switches on the wall / skirting board ( next to the heater ) or one ?

100%. Fit a new mixer and start from there. I think all the problems will go with a working unit. Flow restriction on startup will be minimised then too, so should negate the holding down of the handset to get things flowing. Or change it to a tank-fed electric unit.

Erm.....by the auxiliary switch I kept mentioning? That'll bring it on on demand. Other than that it is already turned on, as the primary switch is turned on is it not? I think we're banging our heads against a brick wall without pics as if you're setup is not generic then we're pissing in the wind here Also it's a convector heater not a radiator.

If you went fishing for 4 hours and drank 1 cup of coffee an hour then you'd need 4 cups worth stored in the flask. If you need a lot of heat the following day you need to store the max amount of heat in the 7 hour window between 00:00 and 07:00 so you don't run out of stored heat. That's simple. "FOCUS!" Heat rises, so the the flap that were on about is not the flap on the controls. It's a full length metal flap at the underside of the heater that stops air getting in thus massively restricting convention heat flow ( hot air out ) eg keeping it stored in the heater until you actually want to let it out ( by opening the flap via the boost control ). Once you open the flap, cold air gets sucked in the bottom of the heater and gets heated by the bricks. That is where the hot air flow out of the top comes from. What comes out must be able to get in, so the wider your flaps open ( ? ) the more heat ( warm air flow ) you'll get out. The more you get out, the faster it'll run out of stored heat energy. Disclaimer : Thats the most number of times I've used the word flaps without my alter ego Finbarr Saunders making it onto the stage.

Change to E10 and then you'll be able to use offpeak rate between 1pm and 4pm to warm you again in the afternoon. Order of events, as is, on E7; cold heater from previous days use 00:00, Off peak kicks in and starts 'recharging' the heat bricks until 07:00 slight heat output as the heater heats, so the room should not be 'freezing', but that can be incrementally increased by setting the boost to 2 instead of 1 ( minimum ) you accept the fact that storage heaters are utter shite and wear a jumper all day at 17:00-18:00 you select 3 or 4 on boost dial and release more heat into the room for the evening until the aforementioned box of shite runs out of stored heat you freeze at night waiting for ABOS to reheat enough to start giving off incidental heat again from ~01:00 Or you use peak electricity to boost in the daytime. There should be an auxiliary switch at the side of the heater which is connected to the peak rate meter. When that's switche on you can get electricity ( heat ) whenever you want it, but use it at your peril as it'll cost ya! Oh, and forgetting to switch it off will be equally painful when you get your electricity bill. Or..... you get E10 and enjoy the 1pm to 4pm on cheap rate e.g. No need to boost with the auxiliary switch and no use of peak juice. Poost a pic of your heater thing at yours as I've no clue what it is or how it works without something to go on

Did you think this thread would be either a) simple or b) straightforward ? "sucker!"

Can't you just feel which pipe gets hot ?

Moving the mixer down is pointless. You can move it downstairs and there's will be zero difference. It's already been said, it's the height of the outlet that dictates flow. Pic seems to be pipe for pipe to me unless I'm missing something And go buy on of these for £50. ?

A problem shared Welcome, and please do a blog. We can start with a picture of your giant brass balls maybe? ( you self building, basement digging lunatic ) Youll fit in nicely. Grab a chair.

If it's a gas boiler then you could manage with a single ( Sunamp ) 12 with ease. I'd say a 9 would probably cut it, but that would be borderline for your house at 212L uvc equivalent capacity. A 12 will walk it, as long as the gas boiler isn't allowed to service DHW according to demand. How about putting the manifold(s) in the airing cupboard and just having the SA in the garage? Less pipe work, less losses and any waste heat off the manifold / connective pipework will keep your trollies warm. Typically you'd only go for a manifold arrangement throughout, and not leave a room out. The idea is not to have any series plumbed outlets thus negating starting off with big dead legs. A HRC with a series plumbed house is quite indiscriminate so you won't be able to discount any outlets like you can with radial + manifold. Get back to the drawing board and see which setup will have the biggest benefit me thinks

Sounds like a negative.

Not all about the size of the house chief, it's about how much water you're going to use . Remind me of how you intend to heat the water please? I'm a veritable feast of random crap like that ? Just make them up as required. Simples. Run that by me again ? Turkey-induced coma at the mo. When you say room, do you mean to all the outlets in the one room? Yup. I believe my next couple of victims are going down the same route. Please don't kick yourself over this........allow me, as the wife says I need to start exercising more. Win, win.
