Ideal logic+

[PrenticeBoyofDerry]

Quick question.
On the "Ideal logic+" what purpose and functionality does the the pre heat on/off mode serve?

 

[towan]

To either Pre heat the hot water in the heat exchanger or not! With it on, the boiler will fire occasionally to keep the heat exchanger at a certain temp, and give you hot water quicker. With it off, the boiler may have to fire from cold, to give you hot water, which can take some time.

Typically, the boiler runs for around a minute every 40 minutes to do this.

As far as economical running of the system, would it have a great effect either way?

 

[bolshy]

More economy with it turned off

Depends what timer you have fitted, have you got the ideal rf programable room stat fitted?

I have a Salus RF.
How much longer would it take the hot water to reach the desired temps with mode off?

Impossible question to answer as every instal different. All it does is preheat the plate to 65 so that when tap is turned on the boiler doesn't need to heat plate from scratch.

You've got to weigh up the inconvenience of waiting for the water to come through versus the cost of keeping the boiler warm at all times. If you have a water meter you then add the cost of the water wasted to the mix.
