How long does it take for radiators to get fully Hot

markin

Large systems will run 24/7 at a low temp, you wont get that instant high temp and cold cycle like in a normal house.

TRV's can stick shut, is everyone having problems or just you?

It's everyone thats having problems. The local MP has now got involved it's even got to ITV news and the BBC news. basically people haven't had any heating for over a week and eon haven't been addressing the problem fast enough.

By who's metric?

It's all very well to say "this should have been done faster", but you can't just snap your fingers and make things work.

Process that should have been followed would include providing portable heaters and then paying the required service compensation once fixed, just like when anyone else has a utility cut.

I have to laugh because sadly its not just a one off something happens every year. But this has to be the worse. 

Have a read

Are you surprised that it's worse when the system is under more stress?

You wouldn't expect to discover many problems when things are off in summer.

😂 It happens every year, it doesn't make sense to start replacing things in December to make the system better it should of been done alot earlier. 

And yes we are all surprised about it because the system shouldn't be under any stress. 

Those are EONs words about it being under stress to make it sound like it's a weather problem. All year round there is problems with Hot Water.

They should service the HIU every two years but they only do that during August.

My radiators are too hot to keep my hand on other than a quick touch within 15 minutes of the heating coming on in the morning.

I've just had my boiler serviced and the engineer recommends setting the flow temperature to 65 deg C in this cold weather.

That will typically be based on your system only. It should be set at whatever it takes to bring your house upto temperature without constantly cycling - so it depends on the amount of radiators you have an overall surface area.

Mine is set at 58 for that reason - if its lower then the boiler will cycle and the house will take a long time to heat up as a result, and if it's higher it becomes less efficient.

Are you sure it's that way around?
Cycling on the boiler is usually when it is providing more heat than the heating system can use (so it stops heating and just pumps for a while), usually due to higher flow temperature.

Yes, if I set the flow temperature to 50c for example then it reaches that temperature very quickly (within a few minutes) and shuts off, then when the temperature drops to about 35c it starts back up again until it hits the maximum again before shutting down again and constantly cycles like that, so the house takes forever to warm up as the radiator average temperature is about 40c - 45c and I imagine isn't that good for the boiler either. With the boiler set at 58c it seems to spend ages between 57 to 59 and the house is upto temperature before it shuts down. The radiators seem to be more efficient at higher temperatures, but I'm not willing to give them 60c+ water.
