Hot water runs cold after filling half a bath only when heating is on
Our systemate 2000 seems to work ok when just the heating is on. Same for only hot water which can easily fill a large bath. However, if the heating comes on in the morning and we try and run a bath approx half an hour later, it only gets half full before running cold. I hear the Baxi boiler downstairs fire up for about 45 secs and then shut down for a similar time as it tries to heat the store, and keeps doing this till the store gets back up to temperature, but I am sure it use to stay on for minutes at a time before we had this problem.
Any suggestions. We have had British Gas out several times and they have changed the middle pump and 3 sensors in the Baxi boiler but the problem remains. Ok now as heating not on so lots of hot water in the morning, but need to get it fixed before it gets colder.
Any suggestions please would be appreciated!

Hi
There are a number of possible causes of this, but the symptoms that you have given don't point to anything specific.
The Systemate range is very similar to the Boilermate, but is made for a sealed heating system. The heating and boiler pumps are the opposite way round too.
It sounds almost as though the unit is droping in temperature too much (the unit should shut off the central heating pump once the store temperature drops to 60deg C) and this could create a problem with only being able to run half a bath. Additionally, if the unit is not full of water, this can have a similar effect.
HOwever, this doesn't explain why the boiler is only firing for 45 seconds. This suggest that either:
1] the boiler s not clearing its heat,
2] the boiler isn't being supplied with a command to reheat the unit from the Systemate control board,
3] the Systemate is working perfectly and the problem relates to the boilers own PCB.
Further testing by a Gledhill specialist would certainly help you out.
