How did you get on?

My worry is if I clamp the brass valve, and the middle section and nip it tight... What happens to the clamp with the white bit on it... Which I originally nipped up. It will likely rotate as well? This (white bit) is connected to a slight corner peice which itself is clamped onto the plastic hose which drops down via the subfloor to the ASHP. This joint is difficult to get to so disturbingly it would be an issue. Hence my concern, way to approach this. Fortunately I've got accident damage cover on my home insurance....

Nut on the right with the white bit is what I nipped up. The middle bit I think I braced off, but the more I think about it... I may have been clamping off the large brass drain valve bit furthest left in the picture. The weep is now on the thread between middle ring and this left brass drain valve.

So I've had a very slow leak for several months, losing probably 1-2bar a month during summer.... Triple that now that winters hit. The system is a 250sqm UFH system and 12kw ASHP. I'm my infinite wisdom I tried to nip the joint up this morning, sealing the original leaking joint (white tip on it) but now the neighbouring one just to the left of it is dripping. I'm not losing 2 bar a day via a slow drip. I'm now trying to debate my next steps. Calling out a plumber over the next couple weeks (peak season?) or trying it again... But I don't want to make the situation any worse. I'm tempted (!!) to just nip the left one up, bracing off the large drain valve (?)... But will this impact the original leak point (white tip on it). I had it all armaflexed up, and stripped it back....temp replaced some, hence so much black insulation everywhere! Any suggestions? Thanks

We're averaging about 19p on cosy, but I think because we cook during the high rate period generally! I'm strongly leaning towards tomato I must admit. Although I do like the octopus app and daily energy tracking.

I can still see them for what it's worth!

Yep, we're 18 months in ourselves! Interesting points to keep an eye on though.

Images show for me, albeit it I don't know enough to comment!

Also if anyone knows if you can check your daily usage/an app with Tomato... im a real data nerd!!

Just wanted to see if anyone has recently done a comparison between these two tariffs.... both offer very cheap periods balanced with more average priced periods. We have an ASHP and do struggle to keep usage within the Cosy periods, but Tomato's 1 - 6 for 5p is quite a potential saving I think. Standing rate is also cheaper, and no high prices at dinner time. Gut feeling has me strongly thinking Tomato will win out, but wanted to check if anyone else has looked into it?

That's really interesting, and could well be cheaper then octopus for ASHP usage... Esp in the winter!

Max output being my slab size, and for how cold it is from exiting a heat off period of 4-5 hours, meaning even with ashp at full chat for 'only' a few hours of octopus cosy period it can't get the flow temp up any higher then 30 degrees? Therefore the 5 deg increase is meaningless, ie.. Increasing top speed of a car stuck in traffic?

For what it's worth we are fairly lightly zoned, basically children's bedrooms vs master room and bathrooms vs living areas....again to try and force as much heat as possible into the small but tall children bedrooms. Morning and afternoon cosy everything is on until thermostats hit 22 degree limits (rare in this cold level temps), but the 10 to 12 is only children's bedroom is give them the extra helping hand.

Thanks very much! mine looks to be: Outdoor temp got water law: 15 degrees ........3.0 Water out temp for WL1 Heat (WL1 floor) 36 degrees..... 43degrees high target Water temp out for WL2 Heat (wl2-fcu) 36 degs....... 43 degrees However even boosting it by the 5 degrees as you suggested, after 3.5 hours of running my UFH temp is still only 29.2 degrees it is - 3.5 degrees outside. We have a very well Insulated property, but a few of the rooms have a small floor area but have high ceilings/Mezzanines. This means they do struggle to get warm when it gets very cold.... Just too little surface area. With the octopuses cosy tariffs I'm less worried at efficiency, vs hammering the electricity when it's only 11p during the cheap rates. Is there a reason I'm not seeing the 29degree water outlet temp getting to something warmer to really force the heat into these rooms? Was hoping the +5degrees would do this!

, I have increased my Samsung water law by +5 degrees to see what it does.... But it's difficult to tell? Can anyone advise in layman's terms please? Thanks

What heat loss assessments and instructions did they leave? Have you managed to check the daily energy use of it? We're using about 32 to 35kwh a day atm, likely to hit 40kwh during this current cold spell? (whole house so includes cooking, dish washer and washing machine/tumble dryer)

We start ours on Monday!

Did you ever get to the bottom of this?

Their original quote was £8k but the original cold call which found her they used the "government grant" to hook her. When on site and quoting they then rang the government and" secured the £2k grant" which meant she only needed to pay £6k for the work!!!

She is semi elderly, health issues and on her own so easy pickings for the bastards. Sadly we're a few hours away and I never knew, had kept an open offer to have a look at her UFH system which also seems to have been done wrong (thermostats wired to the wrong zones by the sounds of it) but never knew about the insulation until the mother in law told us about how pleased she was with it..... I could only chew my own tongue over how no one else found it odd that £6k for a days work should fail anyones laugh out loud test. (along with gov grant over the phone...) She has two mid 30s children who she could have asked for a second opinion!

Apparently lots of it, they took pics and showed her. She had actually been suffering from lung conditions, so the mould would be align to that. Property was cold beforehand (6 year new build,i repeat!) and apparently is noticable warmer after!

Sat with her family, and listen to her Mum talking about her sister and how she has finally got her 6 year old bungalow warmer. Transpires she accepted a cold call from a 'government advisor' telling her she was eligible for an insulation grant. They come and inspected, actually find huge amounts of black mould, wet joists and the felt damp and falling apart. But fortunately they can start the work within a few days. They quote to spray the back mould, strip out all the insulation and make good. They come out a few days later, spray all the mould disappear off, and return removing all the old insulation/damp insulation and replacing it. All in a days work for a few of them. Only cost her £6, with them securing a £2k grant from the government whilst they were in site quoting. I repeat, It's a 6 year old bungalow. Cowboys built the (expletive deleted)ing think, cowboys fix the (expletive deleted)ing thing. I still can't work out how she would have so much black mould, and wet / rotting timber up there though?! FOR (expletive deleted)S SAKE!

Yikes... I think we're 15deg and 3degrees? Does that make sense as a weather comp mode?

Good advice! Any payment before service must be on a credit card. Saved us £9k when an air con company went bust. We paid half via bank transfer first... Then the remainder on credit card. As a result if this order of events Visa declined, but first direct stepped in and covered it.

I imagine you'd lay this, then 9mm board or something over the top and carpet? If upstairs it'd probably work, but if you can get an extra 10 or 20mm you'd benefit. You will also need to run warmer temps to feel the benefit.
