Central heating pipe dropped through ceiling down to rads?.

[egginyourface]

Good evening all,


After some advice on replumbing the central heating pipes in my flat. I live in a 2 bed flat with concerete floors. I was thinking about having the pipe work run up through the loft then chased down to the rad position.

Will this cause the boiler to work harder due to losses of heat ?
Will pipes have to go deeper so wall doesn't crack?
Is it better to use plastic or copper?

In your professional opinion is it better we chase pipes into floor or just run pipes surface?

I've asked a few plumbers that I work with for advice but they all come up with something different.

Your advice would be much appreciated

Yes I'm a lovely spark... Lol

Its only two bed flat but I like the idea of controlling temp in each room. What would you do In your place?

Personally a manifold system feeding each rad = minimum of joints
each room has a stat or programable stat in it.

mods i call for a ban....

we already let croft and mossep in...

thats TWO SPARKS already!!!!

Lol, can't we all just get along...

Do you mean like a underfloor heating manifold but for rads. Is this a more efficient way of heating the place? And what's the maximum zones? Suppose I would need one of those control junction boxes as well

Dead on.
or make one up with 15 or 22mm 2 portvalves yourself.
guardian solutions do 15mm style actuators which look perfect.

less joints, no reliance on trvs to yo yo the temp, i prefer it.

maximum zones? That depends on how good your wiring is :devil2:

You could go about wiring it like me
Come to the dark side

Never seen one of those before. I've wired standard vented and unvented systems with 2 x 2 port valve etc. Also used one of those speedfit wiring centres for ch, how and 2 ufh zones.

My boiler is a combi boiler, would this system work?

I have Myson mptrf smart start controllers in every room and a zone valve on every rad. But also have underfloor heating on groundfloor.

System work easy.

240 to stat, s/l from stat to two port. Microswitch to switch boiler volt free. Common up on all micro switches so in parallel.

you could spend a fortune on controls, you could fit trvs and get off ya arse and turn your rad valves on,off or up,down as needed. Its all about what suits you.

welcome to the forum.

 

[egginyourface]

Just googled it, looks good

 

[egginyourface]

Thanks you all for advice, time to hit the sack

individual control in a 2 bed flat is over kill trvs and a room stat would be sufficent unless its huge
