I need to extend my central heating from my newly built extension into the old part of my house. On the first floor I need rads in the three bedrooms and in the bathroom, utility and lounge on the ground floor.
Is the below ok as a route? It appears best to me to as the joists run as the lines on the paper.
My flow and return come from the extension are 22mm so should when I tee off should I keep running 22mm and just reduce to rads ?
