Flush Toilet - boiler fires up
Hi
We just recently, had two bathrooms completely re-modeled, and replaced and a downstairs toilet where the old basin was removed and replaced with a toilet/basin all in one (the basin is ontop, where the cistern would be)
We have a "Worcester Bosch Greenstar 8000 Life" condensing boiler that was installed about 2 years ago ... what happens now is...
- When the downstairs toilet is has finished re-filling the cistern the boiler fires up for about 30 - 60 seconds before powering back down
- When you run the cold tap (part of the downstairs toilet) and shut it off, the boiler fires up for about 30 - 60 seconds before powering back down
- The utility room, which is next to the downstairs toilet.. if you turn the cold tap off it may or may not fire up as above.
- The kitchen cold tap, will only trigger the boiler if you turn it off quickly, if you shut it off slowly it may not fire up the boiler
- Toilets (x2) upstairs when finished re-filling the cistern the boiler fires up for about 30 - 60 seconds before powering back down
- upstairs (cold) sink taps as far as I'm aware trigger the boiler when closed off
all the above it never did this before, we had the work done.
Thank fully (as far as I'm aware) the washing machine & dishwasher (cold fed) do not trigger the boiler to fire up when in operation.
There maybe "Deadlegs" (I don't know if they are still connected)in the downstairs toilet where the old sink was but they are capped off pipes in the wall that have since been plastered over.
I did not choose the installer, the Mrs did based on word of mouth recommendations. And when I spoke to him about this, halfway through the install.. he waffled on about how the boiler installers should have put an expansion tank in when installing the boiler and then said (when the job has was finished) that it will eventually settle down.
I do recall, that before we started the installation's that in the old ensuite that sometimes using the cold tap in the sink would trigger the boiler to come on, but not all the time. So it may not be a recent development, just the situation has got worse with the works done..
Nothing is plumbed in incorrectly IE the cold taps run cold, and the hot runs hot
Is is something that can be easily sorted because my OCD knows this is not right
Thanks in advance
