Post and beam

Knowledgeable Worcester engineer visited this morning. Nothing to do with cross bleed via the mixers ( didn't believe it was) and apparently nothing to do with flow switch ( i thought it likely was). Basically it comes down to the PID control of the heater when water temperature is falling just below the set point from an already high winter set point temperature. It does not appear to be able to modulate enough to prevent overshoot of the target. A greater engaged water volume in the radiators would allow the excess temperature to have somewhere to go. Upshot is a high temp 'blocking code' that needs about 3-4 minutes before it will allow any more heat to be produced. Bloody software engineers.

I do have a reported crossover bleed issue. Have you watched the video? I cannot see how a bleed over can reduce the boilers sensed temperature down to the same as what comes in directly off the street. And, why that low temperature does not induce the boiler to fire up. This makes no sense to me. I can imagine the possibility of an affect on the shower supply temperature via a bleed over to a lower than desired delivery temperature. But the onserved scenario i cannot imagine.

Really. We are hoping to start our Potton home soon and that is SIP's with a brick skin ground floor and Cedral cladding on the upper. No other insulation anticipated.

Hi John Mo Central heating temp is this high becuase i have not turned it down from the winter. This is still in our current house of 1986 Vintage, not a new build. Yes when it plays up it is all outlets its just that the shower is the most obviously annoying place for it to leave us with freezing cold water. When my furious playing around with everything on the boiler display eventually gets it to fire up it will be good for perhaps a couple of days or weeks. The flow switch was replaced a year ago on a previous engineer warrany visit. Pressure is very good so i doubt its flow related but who knows. The most recent engineer tried to claim that it the boiler was behaving perfectly normally, ( on watching the video) because ' you called for heat and it fired up'. Seriously? Dont know anything about a 'combi save device' Thanks keith

Youtube link: = https://youtu.be/GuhOogbQo5o I am having an argument with Worcester Bosch about this boiler that has misbehaved almost since day one. Occassionally it refuses to fire up when asked to give hot water. I believe the nonsense their technical people are giving me is them trying to wriggle out of their warranty obligations. So i would very much appreciate the opinions of people that know what they are talking about. If i am wrong please feel free to shoot me down.

More than one seller. Not taken for a ride yet as i have not comitted to anything. The highest price was Nu-Heat. The comparison with a Gas boiler install changes slightly when referring to a new build of course. In our case it would be £6.5k just to get a mains gas supply onto the plot. So one way or another it will be ASHP, just need to finalise whether its via the Grant or not.

Yes

I dont think that will help but thanks. I think there will be at least 4 down pipes from our gutters. I have now found a silt trap for £300 but FFS its a plastic bucket when all is said and done.

Following on from my question about a soakaway, i have been looking at the required Silt trap. £400 ! , Why. Regardless, is there a British standard these have to be built to or is it just a case of making sensible provision to capture silt and other crap? If so i doubt i am the first or indeed only person to look at what i can do to install a suitable sump.

That'll work, thanks. I did wonder if there is such a thing as a 'cut out' block already done so to speak.

On a practical level. How is the delivery of service ducts up into the house done when using a block & beam construction? I imagine one of the blocks is cut in some way. Only because removing one completely has got to be incorrect. Thinking of electricity and Broadband specifically to the front of the house today but guess its the same for all the other Ducts.

I may well have misunderstood something about this line? If your pump has to work 24/7 to keep you happy at -2, how does it work at -7

10kW sounds like a lot for a new build highly insulated single storey

Baited breath and all that

I wish i had seen this before i bought my Trail camera last week. Reolink even do a Camo version.

I have just had a look at the Reolink site. That looks pretty good. How has the thing stood up to the weather ? Just seen more information: I notice that some models have a better IP weather rating than others.

I dont suppose it makes a diference but what brand of TF? Regardless, try Heriditas Ltd Shefford House 12 High street Shefford Bedfordshire SG17 5DD heriditas@hotmail.com

I bought a trail camera recently with a cellular capability. Partly as a security camera but initially just curious to know what wildlife is using our plot at night. But i wonder if i could utilise a standard 4g Sim to give me remote capability via a Pi. I am not Pi literate, the last thing i played with was Arduino a couple of years ago. I was trying to build a side real star tracker mount. Now my curiosity is awakened again.

I tried this approach or something similar at least, i wanted a builder to take us from weathertight to completion. Initial interest along the lines of ' we are very keen to work more with Potton and can offer great prices' . They quoted £432k !! Another company quoted £299k to take us from weathertight to complete. Bear in mind we would be at frame erected, roof tiles on, windows and doors in. For a 200 sq metre build. Still finalising each trade on a one by one approach..

Thanks guys. Its a good excuse to learn to use a mini digger so long as i am not wasting my time with regard to BC.

I dont want to get ahead of the BC process and i have not started any works on site as yet. Not ready for house foundations. But i have a little time and access to a 1.5 done digger. So i was wondering, if i practice by digging my 4.5 x 3 metre required soakaway and it ends up acceptable can i fill it with the required plastic crates, backfill and call the job done? Yes i know it will need an ingress channel. Thanks as always keith

Breaking the bond between the Hydrogen and Oxygen i can see. Leaving them to recombine to form the water that will fall as rain somewhere. But ionising either of the constituents will do a different thing will it not?

This is ionising Radiation which is a whole different kettle of fish.

Going through this very saga at the moment with East Herts. We have satisfied a couple of conditions already. 'Materials of construction' was easy. We sent photo's of the brick slip samples, roof tiles and Cedral cladding. For the windows we just told them they would be colour x, from supplier Y, in Alu clad timber. Actually in all cases we stated, 'or similar' which gives us a degree of wriggle room should we need/want it. Planning were good as gold over this condition. Still waiting for a response to the hard & soft landscaping condition, ( 3 weeks and counting). What we did was look at a successful submission from a house 100 metres away that was built in 2018. We took notice of the style and level of detail and figured that was clearly good enough. Our block plan submission for the full planning application contained most of what we decided to show so we basically re submitted that with a new name & date and added a wider driveway and low hedge. I added a note into the key that the driveway and patio would be SUDS compliant without specifying what exactly it would be. This top down view showed the house. drive, patio and a hedge at the front boundary. Rest is grass. Very light on detail to be honest but as i said the neighbours similar version got through. If you dont give much species detail then you dont have to provide specifics or maintenance plans. Grass everywhere mate! The biggest issue i have had with this so far has been getting the drawing submissions into the format and scale that they wanted. See a thread on here about this nonsense. .PDF and at 1:200 @ A1 in our case.

The point i was trying to make is that a lot of the apparent increase in atmospheric water may not be down to the rise in Global temperature that is commonly given as the reason.
