I'm hoping to get solar, but on my barn roof. Whilst my house is listed, the barn is post 1948 so shouldn't be curtilage listed. If I ever get feedback from the CO pre-app then I can start making this plans a reality.
Also want to install a HP, but not down the BUS route.
Instead I want to self install.
I've had some rough quotes form MSC installers, and I can't get the BUS unless the HP can meat the full house heatloss.
I've down my own calcs and estimate it to be 32kW.
So too big for a realistic install.
I can get it down to 12kw but again, I don't know what the CO will allow.
What I may end up doing is a HP self installed 12kw unit. When it starts struggling to match the heatloss, switch back to oil. I can build the controls for this.
As and when I get permission to make insulation upgrades, the amount of oil will keep going down until hopefully one day I can heat 100% from an ASHP.
When I fitted my radiators, I sized then for high temperature, with current heat loss. At say 35 degrees delta T of say 7, they are pefect if I get the total heatloss down to 12kw. So my radiators are about right.
Pipework is a bit small. My additional when I fitted my oil boiler where 28mm, but this joins into the original 22mm primary loop. May struggle to get the flow rates I need, but will test all this and upgrade where needed.
