Hi. I have a triple coil cylinder onto a systemlink. From the systemlink there is the DHW feed to the cylinder. At the bottom of the cylinder is the ECO/Solar coil. I want to pipe the DHW supply through the ECO and DHW coils to make maximum use of the heat output. Would it be best to pipe...

I have a Aquatak 1200. When I bought it, you would not dare put your hand in front of the lance. Now I can put my hand 6 inches from the nozzle when it's on wide spray. The wide spray is only an inch wide so it's not like it's a huge dispersion of the pressure. When I first got it there was...

What is the range of the valve?

The alteration is only to the pumped circuit, nothing is being touched on the gravity. The gravity is working very well and I have already tested it with the power off and the fire high.

Thanks guys. I'll ring the cylinder people and check the coil specs.

Thanks guys. If we do it in paralell: -> existing DHW coil will offer the same resistance as it does now. -> solar coil is slightly smaller in coil length but will only take what circulation in that it's design will allow and not impeed the DHW coil above it? If we do it in series: will...

Diagram shows 3 coils (not 2 - agile) excluding the heat leak rad and solar setup - it's exactly as shown.. so anyway - are we agreed on replumbing it in paralell?

Howdy, I have a triplecoil cylinder that has a gravity circuit and a pumped circuit from a solid fuel stove, both of which are working nicely and well thanks to advice in a previoius post. The third coil at the bottom is for solar, which is sitting doing nothing as solar panel = money...

increase in flow

Thanks to the advice of some, moving the vent pipe to the gravity circuit got everything flying along. Dramatic increase in the time the cylinder takes to heat up. Probably 20 minutes quicker with the correct flow taking place.

That helps a bit. Tank is in the attic where it always was. The feed to the cylinder is 3/4" and the feed out is 3/4" in the immediate run. What it does after that is guesswork. I think it is down to 1/2" quickly after leaving the hot press. The head pressure is fine, given the height but the...

Sister got a load of work done. Plumber was a muppet. Cylinder was left downstairs and 2 new Mira thermostatic pumped showers put upstairs. Of course the pressure from the cylinder is barely enought to get the water upstairs and to the other side of the extension. Would anyone advise on adding...

Yes - cylinder is well vented, comes off the cylinder and across the attic and goes right to the top of the roof and back to the expansion tank, all in 1"

Thanks for your help. And thanks for not bringing your ego into the discussion either. Something a lot of the other posters find hard to do.

The cold supply (unrestricted) is directly into the primary circuit - in drawing and in the real job. I appreciate your concern about the 'what if' element of the design, but there is one person only ever going to be at the system - me. The flow and returns for the stove out of the...

Ehh. the cold feed is open bore pipe. There is a valve on the pipe in the attic, but let's not drift here. Gravity or lack of it is the order of the day. Thanks for repeating what has been said (again). The message sank in a while ago - vent the grav circuit ! So that's it sorted then? pump it.

*Assuming the pretty drawing is as fitted, I wouldn't expect it to work. *Also I don't see this schematic on systemlinks website which shows the cold feed/vent arrangement connected on the gravity circuit The pretty drawing was drawn by Systemlink *the bottom coil should be used for the...

vent both circuits or just the gravity ? they are clips micky.
