Hi all,
I'm not a central heating engineer, can just about tell the difference between a hot and cold tap :) Having trouble working out why my central heating is doing what it does. I hope someone can help me fathom it out.
I have a Baxi Solo 18 HEA boiler, which is about 2 years old and had little use, wood burner.
Boiler has a wireless link to a thermostat in the hall and a thermostat (manual ) connected to the hot water cylinder . I've used Fernox F5, not power flushed, just ran it on heating cycle for about a week, drained system down and refilled, bled radiators. Did this to clean out any sludge.

These are some of the symptoms, on the control panel I switch on both heating and hot water options on continuous setting. System comes on all radiators heat up, burner goes off after about an hour.

The other night I had a hot bath, turned heating and hot water on together, continuous setting.for about 1.5 hours then switched itself off. Now ordinarily what happens after it switches off and I turn on again, only the bathroom radiator gets hot all the others remain cold.
On this occasion I filled the bath up with hot water, once full, as I intended to have a hot long soak and would prefer the bathroom radiator to be warm. I turned the boiler back on and to my surprise bathroom radiator heated up, as well as the others I think.

Today I tried turning the thermostat on the hot water tank to minimum and ran the heating and hot water options on the control panel to see what happened, only the bathroom radiator got hot, the pump is close to it under the bathroom floor, the main boiler is below the bathroom.
I then turned the hot water cylinder thermostat up about a 1/3 turn then all the radiators started to heat up.
As I say ordinarily if I switch system on in morning continious setting, it will run for say 1.5 hours then switches off or burner stops. Later on a bit if start system again only bathroom radiator heats up all others remain cold.
As I say on the control panel I can select heating and hot water together and on continuously, then all the radiators get hot. If I only select heating option continuously then only the bathroom radiator gets hot..... Um :)
Cheers,
Peter. https://amymaytrust.com/
