Wil I still need to wrap pipes under boards in a house, I know in a loft is deffo but not sure on other.

was just trying to reduce the amount of tees ect, would you saythe orange was is better or the purple.

Iv done a quick drawing of the upstairs plan of my house, and was just asking for an opinion, on best route for 22mm flow and return to pick up rads. (x) is were the rads will be total of 11 upstairs and down stairs. Iv also added in different colours possible routes off flow returns. I...

Ha yeah but going over it now it's not clear. I guess I'm asking is the sheathing ok (for electrical cable) I really wanted to use some tubing incase it ever needed replacing.

Right Iv made a start on the speed fit droppers for this heating system. After knocked some plaster off i found the depth of the plaster was only 12mm. I was originally going to run the speedfit in 10mm trunking but found this sticking proud of plaster. I opted for some electrical sheathing and...

When installing 10mm pipe for rads on a heating system, is it best to notch out or drill holes in the joist when tuning then back to flow and returns. [/code]

It will be a combi 34 kW standard 3 bed house

Does anyone know the maxdistance you can run 10mm from flow and return or from a manifold to a rad. With out losing performance from a rad.

I know the sure fire 1 is a different nozzle do to no gas flow adjuster

Anyone know were I can get a nozzle for the first surefire, it's the one without the gas flow adjuster.

Just put a new tap above the old one.

You can buy a pump for purpose tho, like a shower pump and place it at cylinder hw outlet. Same difference ;)

Speed fit manifold ? As you can run Copper also to them, how much is recommended In distance max to run in 10mm from from flow return to rads.

Also with 10mm copper would you still notch out or drill through the joist and run it down.

Then just drill the joist and run to 22mm circs.

I was going go run up not far from around the window, seems a lot of pipe waste going across room to corner and up.

Many thanks for taking the time to answer. It a combi going and I'm going to fo the droppers in speedfit but the rest will be copper, I'm going to manifold from the 22mm circs to 10mm to rads, was going run 22mm as near as can along center of house.

Any tips for running Into the boxes under windows as you can't drop straight into them for nice neat tails to rads.
