Could boiler diverter fault result in my lower gas bill?

Pescur

I have a combi boiler that has a diverter error, I have rebooted it several times and it comes back.

I do not have any heating on so I am surprised it makes any difference to the cost but the symptoms are that the water does not get hot the way it used to, it takes time and I need to turn the flow down to get it consistent.

Like most people I am cutting back on my use of gas to save money but since I had this problem my gas usage seems about a third of what it was. This could be because of the measures I am taking but is there any chance that the diverter error is saving me money?

I am reluctant to get it fixed if that will make it cost more.

I'm no expert on combi boilers but some of them have pre-heat, where they keep the internal loop warm ready to supply hot water at a moment's notice.

If your fault has disabled this feature, it could be saving you gas.

If you tell us the make and model of boiler, someone will be able to say if it has pre-heat and if it can be turned off permanently.

It is on eco so no pre-heat

What happens come Winter when you want some heating if the diverter valve is not working?

Anyone got an answer to the question in bold above?

You're heating less water by a smaller amount.  Of course that is using less.

In the summer we heat our hot water to 40oC rather than over 55oC in winter 

Similar effect of your boiler error we use less energy heating to 40oC now in summer than we do in winter.

The issue is you need to have that boiler fixed for winter. I think someone asked you for the make and model.
