A few minutes looking at the data and it shows a messy picture. But generally, the trend is that the more RE generation there is (less fossil fuels) the cheaper the kWh price is in the USA. It is messy because of the different stages each state is in implimentaion, amount imported from neighbours, and climatic differences.

Maybe they need to install some more capacity. https://en.wikipedia.org/wiki/List_of_U.S._states_by_electricity_production

Welcome Is there a reason that you have chosen Structural Insulated Panels and not other methods of construction?

The pictures are better on radio. One problem solved. Fires in homes are coming under more scrutiny and legislation, so why bother. Another problem solved.

As you are not using natural gas, have you thought of Air to Air Heat Pumps? Regardless of what system is used, plenty of floor insulation will help, best to get it done early as it is hard to add it into a slab later.

The consultation on the new regs finishes in a few days time. https://www.bbc.com/news/articles/cev8mrgky9eo

Will the thickness of the tiles affect the height of where the stairs finish?

Never heard of MIMO, but then, IT people are like chemists, except they just use letters. Multiple input, multiple output https://en.wikipedia.org/wiki/MIMO

Are the nails there for a reason i.e. holding the timber in place. Used in proper engineering all the time. Cost a bit more but are good.

The useful efficiency will be pretty poor initially as little condensing may be happening. The 12.5 kW you have limited to may only be a rough setting and is the thermal output. The efficiency may be down to 65% at start up, which is getting close to 20 kW. Or Was it heating water then?

Where else does one vent off.

Do they mean Building Regulation limits, which are pretty poor.

Spent some time there.

Welcome. Used to live up your way. Do they have a traffic warden again in St. A now? You will find that the term Eco is rather dismissed on here. Low and extremely low energy is the preferred term.
