How do I time the hot water?

Hello.

I would be really grateful for some advice please!

This problem is getting more and more annoying as the weather gets warmer.

How do I stop the boiler turning itself on every time the Boilermate2000 reckons the water needs heating, even when it doesn't?
This heats up the pipes between the Boilermate and the boiler, and as the Boilermate is at the top of the house the top bedrooms are really hot and in this summer weather I have to sleep downstairs.
The boiler seems to turn itself on sometimes even when nobody is using or has recently used any hot water, even in the middle of the night. This is using masses of gas and I don't want all that hot water anyway. Hugely inefficient and expensive for half the year!
If I turn off the whole system at the wall, I have no hot water as when I run the tap it comes out cold, even though the tank is full of hot water!

Surely there must be a way to either: use up the hot water in the tank even if the system is turned off at the wall
and/or: reduce the temperature of the water in the tank
and/or: put the hot water or the whole system on a timer (provided the hot water still comes out of the taps when the system is off of course..)

This system was said to be efficient. I can see this may be true in winter but it certainly does not suit the summer, or is there something wrong with it, or something I have fundamentally misunderstood?

It is a thermal store.
Make sure that your boiler is on max.
When the store has reached temperature it will tell the boiler to stop.

If you have the boiler on max
When having your next boiler service.
Get them to check what the boiler is putting out.
Needs to be 80c

Or if that is ok
Then it could be sludge etc in the flow & return from the boiler to the store.

Or even the boiler pump on the store.

Thanks mike,

I think all of thsoe things you mention are fine.

I think I 've understood that there is no possibility to time it or reduce the temperature, and it is a mystery why the water does not run hot when the system is off but the tank is hot.

My gas bills are not significantly lower than in the winter so I will probably be looking to change it soon.

Not the efficient system it claims to be! oh well!

Hi this is a link to the manual if you don't have a paper copy: http://www.gledhill-spares.net/documents/BM2000-Iss10.pdf

This video shows how it should work and what happens often when the thing goes wrong.
