Hello,
Having recently bought a new property which has an unvented hot water system installed, I'm just trying to understand what's normal and what's not so normal having had no experience of an unvented system in any of my previous properties.
My intrigue/concern really comes from when the boiler should be off, I.E. according to how I've programmed the timings on the boiler control unit there should be nothing calling for heat; thermostat's (one upstairs one down stairs) set to 15c and the hot water should not be on.
However, when this is the case, I'm experiencing the Wilo Yonos Para pump located on the cylinder start up every 5 minutes or so. When this happens I can see the LED on the pump control is a continuous green and I can hear the pump whirring away. This will continue for a minute or so after which the pump will turn itself off (LED is then un-lit and no noise). In conjunction with this, every 10 - 15 minutes the boiler will also ignite, even though there should be nothing calling for heat.
Is this normal operation for the boiler/cylinder to act in this way or not?
many thanks,
