It was my fault! I just search for what I'm looking for and ask on that thread. In a way that is a better system than asking some of the same questions on a new thread isn't it? But Rikki has probably gone - I just would have been interested to find out how he got on - wish people woudl give...

Just for neatness sake I'll add the link to the Wiki on this site about using mains water to flush CH here - I know myself I always forgot to check the great wiki whihc is what attracted me to this site, and also I come across threads like this that might have the answer I'm looking for (I know...

Please elaborate as you seem to know enough to know there is more to it ... Why? (As trev asked above I know, but would be most interesting as to why). Am interested in both solar and themal stores. Like trev I would not consider paying for one of the professional systems of solar...

Kevindgas, I don't think those range work on gravity hot water do they?(Which I must have if I am to keep primatic system.) I know gravity hot water is not allowed on new installations but if there was a condensing boiler which could do grav hot water then it should be OK according to regs...

Rikki, if still around would be fascinating to hear how you have gone on with this - if indeed your blind system did prevent boiling in the summer. Is a solar system with a vent much more dangerous than with a conventional boiler in an unvented system - the vent could get blocked and the...

If a boiler is classed as 30 kw, does that mean that at max it puts 30kw into the flow or uses 30 kw of gas (with 10% or whatever going through the flue)?

The "global dimming" being referred to was on TV some time ago. From what I remember of the program it is not just water vapour that contirbutes to cooling due to sunlight being reflected but other pollutants too. The important point is that the program said that the vast majority of...

Thanks for the advice chrisey. Sooey, I have no problems with the existing system but will have to change 30 year old boiler eventually. New boilers don't work with primatic systems. The existing system as said above is primatic and the pipes leading to the primatic cylinder do have a very...

Thank you Wintonian, your story is an inspiration. I'm a bit disappointed though that your only problem was about whether or not wired in smoke alarms should be fitted . . . I was hoping to learn more about what happened if things went wrong in this process (i.e. you get something wrong, they...

Can the f+e pipe and the vent pipe have any horizontal or diagonal run in them or do they have to be completely vertical from the point where they leave the main flow pipe?

No replies yet but replies to other posts - my original post too long probably! Let me ask bit by bit: Does it matter if the fill and expansion pipe and the vent pipe in a central heating system have a long horizontal run (10m or more) before rising to the F+E tank)?

Caslin you seemed to be asking if you could without doing an apprenticeship be able to (I presume you meant in legal and in skill/knowledge terms) "complete these domestic installations". Not quite sure what you meant by "these" when prevously you seemed to imply you had only done work in your...

From what I understand, on a central heating system the fill and expansion pipe and the vent pipe should be taken off the the main flow pipe before the pump, and also be taken off within 150 mm of each other. (I have seen indications from posts on here that there may be other suitable...

Interesting thread, those photos are great to highlight desirable and non-desirable results. If lifting all or most of the floorboards in a room, is it bad structurally to cut them all in one line, or is it necessary to stagger the cuts? Also, again is best to cut them in short lengths or...

When I read about acceptance to NICEIC for self certification I took it that you needed to work as an electrician (well as an apprentice to an electrician) or carry out electrical work as part of your main work (e.g. you are a plumber or heating engineer who also wires in controls for the...
