Hi All Posting this in case it’s of interest. The NHBC have launched a number of free webinars. From what I can work out it’s open to all. http://www.nhbc.co.uk/Builders/Productsandservices/Training/Webinars/?utm_source=Shortlink&utm_medium=Shortlink&utm_campaign=Webinars_shortlink What better way to use up your period of self isolation by acquainting yourself with building knowledge and regs. Wow we’re a boring bunch ? No idea if they’ll be any good.

Btw @Russell griffiths I’m not joking ..! If the pipe serves a bathroom or toilet then using the hot feed to the room to the cistern will pull 4 litres of water from the tank. A 15mm pipe 20m long holds about 2.5 litres so a flush will mean you’ve got hot at the tap when the cistern has refilled.

We did our own demolition of the old bungalow, gave away or sold all the old materials except the concrete which we had crushed on site to use as sub-base.

Make SURE the trench cannot fill with water. Empty pipes FLOAT. Ask me how I know

Using 10mm pipe seems to alleviate a lot of problems, which is what i'll be doing, as long as the runs aren't rediculously long.

This is coming out next week - Tuesday 7 April. This is the one where architects redesign existing houses within a genuinely reasonable budget, presented via immersive Virtual Reality. IMO this is the best series of all of them for learning about the design process, and with the best involvement of the client in the discussion with the architect. https://www.bbc.co.uk/programmes/m000h3m8 My thread about Series 1: Ferdinand

Why 3 separate coax @ProDave? I did coax and 1 cat6 in current place but don't know if cat 6 will ever get used. Check out @pocster devils corner thread

well you started by introducing yourself and your project. The rest is 'thread drift', which in this case, is good. We like people that have data as it makes life clearer. Now are you going to explain to @Eileen the proper way to show units.

It looks amazing. What a great job, when faced with such adversity, ( shite instructions ) you are doing

I feel you pain. I would have launched that thing down the bloody garden by now.

^ especially when there's a further £1200 for grubbing out foundations. If you have time demolition is the easy part. Plumbing and heating are quoted separately and amount to £12k. If using plastic pipe and fittings that could be nearly half that surely. Does it include any bathroom fittings?

Demolition sounds expensive for crumbling outbuildings; I'd strip it out of the quote and get it priced separately, especially if there are any materials worth salvaging (old bricks, tiles?).

If they count my rental income as well as my actual SE income I could be in line for a bigger grant than I thought.

When I ran my company in Australia I employed 6-8 people, sick pay over there is something employees see as an entitlement they need to use up before it goes out of date..... having workers not turn up because they are using “sick” days up when they are not sick in a bloody nightmare for a small company that relies on a set amount of people to make a functional team of workers.... and if you add up 6 employees all taking there sick pay at random time’s this actually causes a huge financial burden / disruption to a small company. To get round this I told all my employees that ALL outstanding sick days not taken would be paid out as full days wages With a bonus at xmas each year. Suddenly nobody was sick, work was uninterrupted and everything was sweet. The lads were stoked at xmas as they would all get a sizeable sick pay payout plus bonus.

What will be your hot water source? My layman's experience is a good chunk of the delay on hot water is waiting for a combi to fire up. If you're on a tank this is cut down

I have one question about this house, how did he install his foundations?! Surely he couldn't get concrete to that location. I wonder what he used in place of it?

Just a heads up. Amazon have the Firesticks on special offer just now for a limited time. I have just ordered one for £19.99 https://www.amazon.co.uk/Amazon-Fire-TV-Stick-Streaming-Media-Player-Alexa/dp/B0791RGQW3/ref=sr_1_1?keywords=fire+stick&qid=1585684368&sr=8-1 I have been looking on ebay and you would struggle to get a second hand early version one for that. I don't know how long the offer will last.

I think you need to bottom out what the real heating requirement is, and work from there. At the moment there's a massive discrepancy between what your architect is telling you, which suggests a mean heating requirement of around 300 to 400 W, and your UFH figures, which suggest a massively higher heating requirement. If both floors are heated (and this is worth thinking about, as with a passive house spec there is rarely a need for first floor heating) then 205m2 at 50 W/m2 is an absolute maximum heat input of 10.25 kW, and frankly that's the sort of heating requirement that a 40 year old house might need. Something closer to passive house spec is unlikely to need more than about 20 W/m2, so that would be a peak requirement of around 4.1 kW. Our heat pump is rated at ~7 kW and cost around £2k installed. It's massively too big for our needs, but was the cheapest unit we could find at the time.

This is another clue that the 16.5 kW figure is way too high. A £250 oil bill, according to the architects calculations, with an 80% efficient boiler, would be around 3,571 kWh for the year. Hot water will be a fair hunk of that, roughly 1,000 to 1,100 kWh per person per year, so that needs to be subtracted. For two people, that would mean that heating energy use would be around the same as ours, about 1,500 kWh/year. That doesn't stack up with a 16.5 kW heating demand, as our typical heating demand is about 300 to 400 W, and in extremely cold weather this can increase to about 1.6 kW for a short period. It sounds to me as if a decimal place may have been shifted to the right by accident.

£50 quid says once SWMBO realises this I’ll have to put a lock on the bedroom door anyway . What a joke !

I think a multi tool will be hard work, slipping ect. I would prob go for a series of small drill holes, going larger to link them, and then file it out...... Ok. Ok. I would bin the lock. Who needs that level of privacy

thats just what my road and house clearing has felt like .LOL

Looks like it will only work if you can show that the credit agreement additional information was not clear and concise. I think I will look on with interest.
