I'd follow @Temp suggestion, a couple of key locations in the house to run cat6e to, if you're building though plan to put it the router/cable centre near the riser so you can run more when/if needed, thinking Poe cameras etc.

We're at 9.2kWh gas per day for hot water only - no idea if the hot water schedule is just enough or overkill (1 hour per day on a 210 cylinder). (system boiler, no seperate immersion heater) Electric is average of 19.1kWh per day, this seems steady in the time i've been logging the data (5 months)

It's videos like this that make me really regret not pursuing architecture and landscape architecture when i was a kid, thanks for the link @Ferdinand!

Thanks for the link and responding

Another nod for starlink here, we shifted onto it about 12 months ago and the difference to the "fibre" we had previously was night and day, it's 3 times the cost, but it's reliable and around 15x faster than the copper connection, which was also desperately unreliable based on our location.

I know it's been a fair while since this thread saw action, but @severnsidedid you decide what to do with the air to air system?

I’ve used a Brinno camera, they are specifically for Timelapse and once in a water proof case are ip rated. A single battery can last months and a decent memory card means you don’t have to empty it all the time. main downside is the res is a bit low, but I’ve found it really good.

Could the chimneys be treated like how a stove liner would be installed - so a duct pipe down the chimney, a register plate at the room entry point and the rest of the gaps in the chimney backfilled with insulation beads?

The house has a 100amp fuse, and we’re consuming between 12kWh and 30kWh per day with current use, depending if the car is plugged in to charge. gas usage is still manually collected, but the electric house consumption has been tracked in home assistant since bulb made the smart meter work again. That said we haven’t used the gas for anything since 14th of may. good news on the stone walls though!

fantastic! thanks @SteamyTea i couldnt find a working link when i browsed the thread - this could be due to tablet browsing mind (just occured to me).

This was actually what lead me here , but the site and excel calculator seems to be offline now the house has solid stone, solid brick, a small amount of empty cavity, areas with no dpc foundation, dubious decisions made on pipe, electrical runs as well as insulation choices. typical old extended house i guess based on your 400m2 example, ours is closer to 200m2, and the installers i've managed to talk too have all listed 12kw minimum with potentially 2x7kw running in sequence which naturally need £ of additional electrical changes to carry that much load etc etc.

yep, 12kw at least is the initial quotes we've had, and solutions start getting ugly at that size. What can we do? tough one, its double glazed and roof insulated but the mixed mode of building evolved over 200 years has left a right mess to try and insulate and get rid of the biggest problems without utterly destroying the living conditions at the same time. Current plan is to get a full heat loss calc so we at least have a baseline understanding of the 'worst' case and we can then start building up from there.

sketchup is definitely a good option, it doesnt take a lot to make it work for basic stuff, a couple drags of the mouse to make a box and you can import floorplans to map them exactly if you need. when we were exploring house moving we used it all the time to really quickly flesh out layout plans based on the estate agents details - it often highlighted mistakes and missing details in the descriptions and was big help when sleuthing houses with no floorplans.

what about something like this - you mention you wanted access to the operational side of the house from the two entrances, this plan gets the plant out of the premium middle space (maybe bad for runs - dunno!), combines the wetworks into a single space (dog and wc shower room), retains the big util laundry aspect, and shrinks the cloaks but provides access for both entrances to easily access all the messy bits.

Heya, Just stumbled on this amazing resource in a completely unrelated search and had to register immediately as theres so much good stuff on here. We're based up in northumberland, we have a house and a .13 hectare garden (iirc) on a 38 degree slope, its a bit challenging i'm really enjoying building stuff, primarily of timber, last year the lockdown project was a 2.4x4.8 workshop, this years has been a retaining wall and will be a 2nd shepherd hut as a home office. The search that brought me here was actually a 2017 thread covering heat loss calculations, as we're looking at a heatpump for our EPC E house, not such a joy project
