While it may be good in principle, in reality how do you do it ? Infil plots are rarely large enough to plant extra trees and who wants trees anyway with the potential for damage and maintenance. It's just a tax plain and simple.

just the normal house NAPIT type cert was all we needed.

id let them add all the conditons they like, secure planning. then appeal the conditions with costs. its free so nothing to lose. Unfortunately dead head civil servants are completely unaccountable in the country so can literally do what they want with zero repurcussions.

overthinking it. just leave them on auto with a fan on/off temp set then let the heat pump control them.

ideally you should be using marmox on the inner skin all way round anyway.

not true actually. If it were the case the bank would be on the hook for all the liability and you would be a tenant. You are allways the owner, the bank has a legal charge is all.

id stick to 75mm screed, not much cover above the pipes with 50mm

i did think the same but its massively more costly and hassle to do underfloor for 1st floor. In the end its not needed, if anything upstairs is too warm at night even with heating on fallback after 6pm. Bathrooms we have electric wet rads all controlled by home assistant as somewhere to dump spare solar/free sessions and ride the cheap rate sessions. Karndean floor is not cold once ambient air temp is 21 anyway.

needs planning, truss company needs to know so they can account for the weight, will probably need to sit on a stud wall below to take the weight. You need to lift it 400mm off the 'floor' of the loft so you can insulate under it, there is risk of freezing. https://www.discountheating.com/telford-tempest-300-litre-unvented-horizontal-indirect-heat-pump-cylinder.html

exactly. i think they are more for heat but at the price would take several lifetimes to pay back.

yes of course, its good idea as you will get invert levels for drains etc as well.

Looks like it

yes will be fine, you need to order ballast.

could install a loft unit to force airflow https://store.beamcentralsystems.com/products/axco-loft-mounted-positive-input-ventilation-piv#:~:text=Designed to run continuously%2C the,generating fresh filtered air throughout.

crap, made zero difference to cooling. Hoping it will be better for heating. Definately wouldnt bother with one again.

of course any of them can, highways,sewer etc etc

waste of time upstairs really, shouldn't be a need for heat in bedrooms with a well built insulated and air tight house.

be aware a pre-app doesn't necessarily goto all the statutory consultees any of which can kill the application even if planner approves.

err, simplify. zero zones and open loop. nice and easy

bit like speeding, only an issue when caught....

careful, you need a licence to use those. Big fines if caught.

hire a towable bowser from trav/brandons etc for peanuts a week and fill it at home ?

dont forget fancoils are very good for heating as well, small footprint large output.

would lose a fair bit of space to mount them as they are very deep, could be a solution for hallways/landings though. Just check they have a condensate drain.

agree, simple and straightforward process.
