Hey Kop, sorry mate, my fat fingers! Didnt mean to press that!
I was gonna write i totally get why you are the king of pipes! Very tidy work. Great stuff.
So after much consideration i think im going bite the bullet and chase and solder 15mm copper to chrome in the walls and pressure test before dot and dab.. although really like the look of that 10mm work..
I have a final question regarding zoning..
The bungalow is 110m2 but believe it may still need zoning.
The living space is just 3 rads, the rest in bedrooms or bathrooms.
Am i right in thinking i can tee off the 22 flow from the boiler to feed these 3 rads and just tee the return back into the return for the bedroom / bathroom rads?
Can Etrv valves be used as a zoning alternative? Are they building regs compliant, and essentially plumb in up as originally planned above. One flow and return feeding all rads?
