How to Balance Your Heating System, Everything You Need to Know & REDUCE YOUR GAS BILL

So the way I understand this is: if I have pressure modulating pump I don't need auto balancing valves. Having them installed in the system with pressure modulating pump might create conflict between two as the valves will control pressure(independently)as well. Or, am I missing something?

How to find what radiator is first, second, so on and last radiator? To know from which radiator to start and ending balance

What is the point in this if you have TRV's?

Delta T is not the average temp.

Delta T should be the change in temp between the inlet and outlet.

I've just tried balancing my system based on radiator size. The smallest (about 500 watt) radiators had the lock shield on quarter open, the intermediate (about 700W to 1 kW) had it set one turn open, and the largest (1600 watt up to 2200 watt) were left fully open. What do you think of that approach? Seems to work with the large radiators coming on more quickly, but since its August I can't properly test it out. To me it does seem logical to match the flow to the radiators ability to dissipate heat.
Background - each radiator is fed by microbore, so the pipework probably limits flow rate.

Please help me
I replaced 3 radiators after that, and all systems blocked 🚫 mean 10 radiators not working. I drain all systems air out from radiators still not working kindly please give me the solution what wrong 3 meter pipe next boiler very hot after that not hot aswell
Please help me
Thanx

30years in plumbing and still smiley!!!

Best advise on balancing, I've looked at several. Many thanks

Remember to bleed the rad before you balance them, and make sure the heating is turned on max.

I got a system boiler with invented cylinder. 11 radiators. How do I know which rad is first or last?

Also how how to balance the cylinder tank?

Very detailed explanation Mark thanks,but it does seem like balancing is nearly impossible to do,and to achieve it means spending many hours and lots of money on new auto/smart valves, measuring kit etc,plus more gas when testing,the previous videos i have seen all say measure temperature difference across flow and return pipes when system is hot,so bit unsure how it can be done when the system is cold ?,also i have 2 new aluminium middle connection radiators in a recent extension that dont get very warm the heat isnt spread out across the entire radiator it just seems to be hot in the middle and on one side,i have been using a thermal imaging camera to identify the cause ,but not getting very far,I am liaising with the supplier at present but they don't know why,would you have any thoughts Mark.?

Thanks much appreciated, most of my radiators only have a 2 or 3 degree drop, so going to have a go.

Good communication, explaining the variables and use of technical improvements.

None of that works for a Heat Pump or does it any advice would be nice new vidio.They keep going on about 35c how does that work

Excellent content mate👍

My damn pipes are made of plastic i cant measure on them. But my question is we heat the house with coal burning boiler and a 500L hot water tank if it is warm enough in the house isnt it more efficient to send as hot water as possible back to the boiler so the fire will burn less intensively and use less coal ?

Hi,
I have a modern condensing combi boiler system with a flow temperature of 60 degrees.

I have currently gone with a temperature delta between the flow and return of 12 degrees on each radiator that i can, but some of the further radiators are still not getting adequate flow/warmth. Would it be okay to aim for a higher temperature delta of for example 18 to 20 degrees to help balance the system as the system is incapable of balancing with a 12 delta between flow and return on the radiators that are getting hot.

Kind regards.

Really good video. Will Drayton auto balancing valve bodies work with other smart TRV heads, like Hive etc?

Why does the pipe leading to the TRV on some of my rads get hot first?

Good vid, thanks. In ductwork systems where you can’t have control dampers, we balance the system by selecting size of pipe and number of bends etc. and calculating pressure drop in each leg but it’s more of a black art with small bore water systems.

Is it the same process for small bore systems that are connected via a manifold?

All my 5 radiators are cold at the bottom but they were fine just last season. Would it be central heating pump malfunctioning or a sldge in radiators?

What dual thermometer are you using

I’ve followed all your videos on cold radiators - took it off and flushed it, changed the thermostatic valve, then changed the lock shield valve, now I’ve balanced the rads and it’s still the same - hot pipe to the valve but radiator still cold. Any more suggestions?

Hi regarding the hot water tank what should be the temperature difference flow and return difference, when it's just DHW demand , from cold. I have a system boiler heating a tank indirectly with CH. Thanks

I'm a not a gas engineer, just a home owner looking to save a sheckle or two. I did buy a digital thermometer to balance mine as they're not too badly priced now. This is the first video I've seen that doesn't tell you to open all the TRV's and lockshields fully, turn the heating up full and find the order they heat up. Then when the system has cooled set the boiler temp and go round in the order of heating, altering the lockshields as required to get the temp difference.

Another good video, Mark what's your opinion on the DANFOSS RAS-B2 trv's, are the better than Drayton TRV4's.

Useful video but do I need to go to the rad nearest the boiler or the hot water cylinder/pump first, then the second nearest one and so on? I'm assuming the hot water cylinder as that's the thing that pumps out the hot water not the boiler, so I'll try that first. No, that can't be right as the hot water in the cylinder is just used for hot water for use in showers/bath isn't it? The hot water that circulates round the rads comes from the boiler, doesn't it?? I need more knowledge on my system before I try to fix the cold rads I have! Hashtag beginner....!

It's difficult to achieve a temperature difference of 12 degrees for a small radiator. Also it helps if no-one is running a bath or shower when balancing the central heating system.

Hi my boiler shows burner symbol sometimes. Is that good or something is wrong? Thank you.

Great information

Wish someone would explain how to balance a mini bore system with manifolds hidden above ceilings. I have 20 rads and it’s impossible to run around the house to see which rad gets hot first.

I don't have thermostat valves on my rads they are the same at both sides so how do I know which is which 🤔🤔🤔

👍🏿👍🏿👍🏿 Mark 💯%

So basically - balancing is impossible.
