All Activity

Honestly. Can't work out if it's brilliant or mad. Getting Multiple Claude sessions to literally talk to each other so they dont stomp on each other's commits. But just had to tell one session off for (expletive deleted)ing about and drifting. I demoted it to help another sessaion as an advisor!. I can see it grovelling to the other session and offering its support and knowledge. Bizarre to watch. These is all MY BITCHES

I have a UFH design, done by the company who'll be doing the screeding. They are able to supply quality components without the mark-up the likes of Continal et al enjoy. But what of the Supply and Return pipes for the manifolds? We haven't bottomed out an ASHP design yet and ideally would prefer to kick this can a little further down the road if possible. Is it normal for these pipes to be placed in the screed to be considered later? There is a manifold in the Utility Room, very close to the ASHP (no need for buried pipes?), plus one in the Kitchen and a possible third one for the first floor (I can't imagine that needs considering in the ground floor screed).

Stunning - lovely blend of materials and the chimney - well a piece of art. 👏

They will definitely wander off. And they need access to shelter, food and water. Domesticated goats are not particularly hardy.

Maybe I'm overthinking it, it's normal for me. 🤣

But do you really need a dehumidifier with MVHR is winter. Our humidity levels are pretty low anyway. Overnight and they are dry next morning. MVHR doesn't even go into boost. We only dry stuff that doesn't going the heat pump dryer.

talking to a local farmer who had goats --he says no --they will just wander off

We dry the washing in the winter with a Meaco dehumidifier in a small utility room. No windows in the room and a machine load of washing dries in about 8 hours.

I was thinking the same as @Mr Punter why do you need to close it?

Once the restrictions pass do you even need to fence goats in? How much are they? Can you just let them wild and maybe they will stick around your place if its good eating.

Yes Clarkson did this on Clarksons farm. Not really revisited so unsure how it worked out for him.

There's a chap near us that does robotic scrub clearance. Too far for you though. https://www.facebook.com/p/Nigel-Stevens-Scrub-Clearance-61561133578989/

I've used the Quinetic wireless switches from tlc-direct for cases where I've missed a switch like this. Since the switch is self powered it can even be in the bathroom.

Yes we managed 0.2 on the PH scale. It did need thinking through and attention to detail everywhere but it came out OK for us. We did all the air tightness work ourselves so did not rely on trades to do it.

The standard requires <0.6 ACH @ 50 Pa, but not because it's hard. When they build the first Passive Houses they found it easy, with proper care & attention, to achieve 0.2 to 0.3 ACH, so reasoned that 0.6 was a readily achievable goal.

+1. If built to PH standard, then you won't need much heat nor a conventional heating system, but adding UFCH loops costs little. Add a Willis heater and you've got a cheap heating system, or a heat pump for heating and cooling. You're not alone. When they built the first 4 experimental Passive Houses they didn't believe it would be possible either, so they installed radiators. They were rarely used - after 2 years of temperature stabilisation heat demand averaged <10 kWh/(m²a), except for 1996//97 when it was 1 kWh/(m²a) extra. Last year the original gas boiler was replaced, after 34 years, with a communal 8 kW heat pump, providing hot water & space heating to all 4 homes. From memory I think they are all about 150m² floor area.

Me as well. SWMBO wanted the vanity as clear as possible as the room is so small. So I plan on having this within the wall, with a window opening. Vanity over the top with the rear cut out so I can access. Sounds ok in theory.

10/10 for plumbing, but I am very much at odds with the location!

PassivHaus is a means to an end. The goal being to tread lightly on our planet and minimise carbon emissions. In a way it's a little dated in the sense that to achieve that goal it can (depending on situation) be cheaper (financially and environmentally) to put more solar panels in than do some 'heroic' engineering to achieve a set energy use per/m2. (heroic in some buildings who's architectural concept didn't consider passive standards so now an energy inefficient form has to be forced to be energy efficient - not saying that's your case). Being a sealed box is overengineering, building to a passive standard case study of balancing lots of variables and moving forward with the most efficient way to achieve the goals. Over doing it likely just ends up consuming more carbon in building materials and a lot more money in consulting fees. Once you have a target, there are often multiple ways of achieving it. For example, solutions like Aerobarrier can bring low air tightness scores for much less effort than traditional methods. It needs a good base, but the most difficult part of airtightness is the bit that Aerobarrier does in it's sleep.

Update: We got the MVHR, and disconnected the fan part of the shower light so just use it as a light. The house has no damp now, which is great. Takes time to clear kitchen and bathroom compared to extracting directly so it does get misty but not unpleasantly, we should have got a separate boost button outside the shower room but didn't think about it at the time. It's super work in kitchen and bathroom even early morning so very happy.

We are getting slightly more than expected. Btw heat waves can cause slightly lower power - it would best with lots of light but not necessarily lots of heat. We've had an amazing 10 months since getting it installed, nice big payments from the electricity company for export.

I thought it was interesting, do you work in the building trade? Although i do hope your wrong as i have used pir boards in some parts of the house!! I have spent years trying to work out whats best to do, i think not buying an old stone house is a good start lol. Thanks for posting, carl

I may be wrong but walking about my house this summer in bare feet i think the sun is actually heating the water in the UFH by heating the slab so the whole floor feels same temp and my windows are not that big

Beware the great (PH) believers, aka salesman. I fear you may regret this decision......
