Hello all. I've a 8 piece set of LED puck lights to wire up under the kitchen cupboards. 12v, 2A DC. I've previously used speaker wire to do jobs like this but i couldn't find anything like it locally anymore. (Amazon effect huh...) I've picked up a reel of 24v 2A bell wire. I've twisted/Zip...

This really. Really.REALLY ****s me right off that the industry and it's agents ensure that you have to become an engineer to get something correct fitted correctly. Absolute ****show.

If they are stuck open, are they Myson? The plastic goes brittle after a while if so and can cause the latch to catch. Just snap the plastic off.

Typo on the point in the middle. Should have read "full". Aside from knackered, badly designed, old systems, i fail to understand, nor has anyone tried to prove, why, the rad(s) have to be throttled aka "balanced". Your point about pump modes confirms mine. You have to match the pump to the...

Nice to see someone using the math.

You actually mean: "how do you divert the flowrate from some zones to others?" Does throttling all rads (including the poorly behaving one) seem a good idea (balancing)? No. Of course not. Do you look to make all rads work equally bad? No. Of course not. Does this approach work with modern...

https://www.newtonnet.co.uk/permanent/GrundfosDocs/BypassCommissioningAlpha2or2L.pdf They actually don't. They say "if... must" It's a fudge solution which they admit isn't ideal for obvious reasons. The last paragraph is the key. "Use a manual bypass".

Great answer. But, "Balancing" as you've put it does NOT ensure the space is heater up evenly (With-respect-to other-spaces). Quite the opposite. This is why i have such a problem with the whole thing. It does nothing to consider the causes, only looks to provide a blanket solution to an...

What is it you think is being balanced?

Detailed answer. Thank you. CP really demands a low loss system with very little friction losses or delta between emmiters. It is a pressure biased system, not flow and flow is the primary condition we should be worrying about (ignoring knackered plumbing). I could get away with CP in my...

My hot temps are 21c. I have rooms that are left off during the day (bedrooms and bathrooms) and they naturally fall to ~18c. This is the same for the rooms left off overnight (downstairs) which drop to about ~18C. Down time is about 10hrs. Room Heat up time is rapid when called. (Probably...

30kw boiler for 7 rads? I have 11 rads and a 15kw at.a.push. old condensing boiler which feels too much even though its 20 years old.

The great carbon scam in effect. Or why low temp heating systems might not be all they are cracked up to be because they are slow to react and need to be working 24/7 everywhere. Zone everything anyway. Every rad. Every room. Better looking at it than for it. You might find that your heat...

Can i ask why you are continuing to think CP is a valid pump mode?

Ev fires are not a valid concern. If you are looking to throw a anti-ev narrative, there is much better ammo available.

Exactly. As the tech develops, this will be quite the norm.

A great example of the absolute twaddle repeated about radiator "Balancing". You've quoted stuff there without a dogs clue as to what or why.

Quite unusual to have a domestic gas appliance run of lpg. The OP read as if this was a normal existing gas hob. But, in reality it's a new gas hob and you run it from lpg. Any other info? Do you live in a caravan? Who fitted it? Is it new? What's the make and model? How old is it? Do you...

Hydrogen in domestic installations is batshit mental. Both for production and usage. Another example of the great carbon scam

Which bit of the story have you ommited here?
