30kw WB gas boiler. It is my partners house, so something I am aware of. Pipework all mine, except the gas, so no bother there.
I need to investigate it more.
How can the flow rate be confirmed/checked?What flow temp is that at tho?
I've just installed twin 150L OSOs and they state recovery rates at 80 degs flow!! Still, makes it look good 😱
apologies for my ignorance, I am not technical at all.Its the boiler flow temp that OSO quote at 80 degs. Most boilers closer to 70 so recovery rate way longer than stated depending on coil design (ability to transfer heat).
The cylinder will only heat up at the time in the instructions in ideal conditions. Unlikely in real world situations. Time the hot water to be on without the heating so it's coil gets the boilers full output and it won't take too long. Have the heating on and it will get a share of the boilers output. Best to set hot water to come on one hour before heating times.
We now fit a circulating pump on the hot water from the cylinder. Combi heats it fine, all hot water taps from cylinder so no time lag. Put circulator on a ceiling mounted proximity sensor so that runs for 15 minutes when activity in the bathroom area. The kitchen sink near enough not to need circulation.
That’s also what we were saying mate😀😀Combi on unvented is fine. If you’ve got your 2 port valve and all other G3 kit installed correctly then there nothing wrong with that at all. Assuming it’s installed correctly the coil is just like another radiator
