My MiL has a teeny 1 bed cottage which came with a Pulsacoil BP 120, and TBH I don't really know what to think of it.

For a single occupancy home, with no bath, this is feeling like overkill? It's a big old unit, presumably with and 120L tank? Although it's a heat exchanger so is this the volume of heat it stores to instantly heat fresh water piped through it?

At the same time though it also has a tiny little header tank in a cupboard above it, and so I think I understand that this unit is responsible for all water pressure, hot and cold?

Outside of the header tank apparently needing draining occasionally to stop it overflowing (any tips? I was confused that running cold water didn't seem to influence the level on the little tank) it's all apparently working OK with Economy 7 and all, so one approach is to just leave it alone!

So... is this kit any good?

Family member has a converted stone stable. 21in thick solid walls, with 3in internal insulation. Two storey, low ceiling, vaulted roof, fully open plan bar wetroom, around 5m x 3m footprint.

Currently has a storage heater on each floor with an Economy 7 circuit. Not too clear of the water situation TBH, two "water heater" circuits on each fusebox (small on for E7 I assume) and a big chunk of hardware in a cupboard bigger than a washing machine labelled as being mains pressure water heater but not clear how big the tank is and exactly what it is in all honesty. Wonder if it's actually oddly overkill.

Looking at moving the storage heater for a building project but then naturally there's a number of hops until we're saying let's ditch them and go with... What?

Requirements are pretty small so actually not hugely sure a BUS grant derived system makes much sense? I like the idea of an A2A for the heating side but then don't really know what happens with the water side of things. No bath, so minimal need for much volume of hot water shower and sinks.

If I looked at A2A self install I think I'm done for under a grand. So the A2A grant seems silly maybe? I guess some installer would happily take the other half of the 2.5k for the install if it's all free money though. And as above that leaves the water side unaddressed, but without any existing radiators, any new installation would still presumably bust out over the 7.5k?

I'm assuming you'd still want a dual A2A pump btw? Upstairs and downstairs even if the overall volume might fit on one technically? Lots of height in the building so you'd want to be adding more heat downstairs on winter and more cooling upstairs in the summer?

I think it was my dad who told me years ago that homeless people in London would be offered a day trip to Hastings to cheer them up back in the 1950s or such. And the coaches would then accidentally leave without them. Whoopsy!

Anyone know if there's any truth in that at all?

Howdy, I've a quote for a heatpump with 5 radiator replacements and so I'll sort those out myself in advance (some I can just move between rooms, why buy new?!). In general though I'm confused that each room as it's own heat demands even when come rooms are open plan.

My kitchen radiator is deemed OK, but my dining room one is not, even though these two spaces are fully open to each other with a 3m wide opening at the narrowest part.

Can I not potentially upgrade both, knowing that collectively they will then exceed 100% of the requirement of the combined space? Naturally circulation is an issue in a large space, but that notwithstanding, surely it's not the case that the fact I basically just changed the floor type at a certain arbitrary line means a specific radiator has to change?

Also the hallway radiator is only listed as heating the hallway, despite it naturally being open to the landing. I heard a rumour that heat likes to go up, so obviously much of the hall rad's heat will go up to the otherwise unheated landing, but that's a different "room" so doesn't count?

I don't want to start thinking the survey is daft, so if anyone can clarify what feels like a weird oversight in common sense, I'd appreciate it!

I'm painting a mural on my daughter's bedroom wall, and it'll all be turquoise, but I need maybe 15 different shades of the main colour.

What paints / eyes should I be using here?

Even until writing this I assumed I'd be using standard wall paint and either adding equally standard black or white paint to the base turquoise, but maybe even more that's wrong?

I've just over a metre square to paint in total, about 100 polygons making up a swimming turtle, so advice very welcome!
