Just looked at the valves on the vertical rad and both valves are fully open. all the other radiators lockshields are only open about half a turn. Should the lockshield on the vertical rad which is the last rad / at highest point be fully opened or partially open?

water is coming out. But I let it out in small amounts. No air.

the pressure remains steady around 1.6. I bled it when its warm as that when I notice it isn’t hot like the others. But there’s no air coming out. I bleed and let the water out in small amounts for about 10 secs and then it heats up fully. The rad has fours panels and the flow side always...

So does this sound like a balancing problem?

How long would this take. Generally, after bleeding or balancing the vertical heats up and then the problem starts after about 10 days. If the system wasn’t balanced properly, then would the problem always be there?

It does squirt out a lot of water. Inhibitor was put in. The new boiler was installed about 2 weeks ago.

Could this just be a case of fine tuning the balancing? The installer balanced the system when installing the new boiler recently. Should I turn down the other radiators more (they are all only 3/4 open)? And should the flow and return on the problem vertical radiator be completely open?

not sure about the pump buts it’s a new Intergas xclusive36 boiler.

Tried those but didn’t fix the problem

yes

boiler is on ground floor. Pressure is set to about 1.6

We have a vertical radiator in the loft. All the rads were balanced and the vertical radiator was heating up fine. But after about 7-10 days found it wasn’t heating up as well. When I bleed it no air comes out and after about 20 secs hot water finally starts coming out and the radiator warms up...

Oh well... ;)

Finally had the xclusive36 installed. I do find this is noisier than my old vaillant when the hot water tap is on. Anyone else find their intergas noiseyin comparison?

I guess we’d be happy or none the wiser if any one of these were installed ;). Just looking for some comfort in buying one over the other.

really helpful to know. Thanks.

Hre36/40 specs: https://www.intergasheating.co.uk/specifier/products/hre/hre-36-40/ xclusive36 specs: https://www.intergasheating.co.uk/specifier/products/xclusive/xclusive-36/technical-data/ Is the hre36/40 a better spec than the xclusive36 or am I not reading the specs right?

Just came across the xclusive36. Anyone know what the difference is between this and the hre30/40? With the hre36/40 seems you have to buy a fitting kit which brings the price equal. Which one should I got for?

With no real price difference between the hre36/40 and 40sb, wondering it makes sense to go for the hre36/40 now and if required at a later date (and if im able to find space somewhere) to add the cylinder later.... ??

The reason for going for the 36/40 is purely to get heat to the radiators which are spread across three floors and wasnt sure it was worth compromising by going with 36/30. Re a small cylinder, can one be fitted to the 36/40? If so, any suggestions?
