@flameport Don't most passive splitters pass power from one or both downstream ports? Most listed here seem to: https://cpc.farnell.com/c/audio-visual/aerials-satellite/amplifiers-distribution/splitters-combiners

I have a quattro LNB feeding a multiswitch. Can I use passive splitters on the VL, VH, HL, HH cables. I want to connect a Sat>IP server which only exposes all eight of its tuners when its connected to a quattro but while testing I need to keep the multiswitch in service. If yes anything I need...

I suspect that when both your zones are operating the total flow on the secondary side exceeds the flow on the primary side causing (I assume unwanted given the question) reverse flow through the header. This might be made worse by the fact that your Zone 2 flow is adjacent to the Zone 1 return...

Apologies I have no experience running the TBS cards under linux. However I use the TBS quad tuner DVB-S2 card under Win7 (32bit) and its rock solid. So too was a quad TBS DVB-T card that I've used in the past. There is a TBS 8 tuner pcie card that initially was released only with Linux...

@oilhead I understand that its on-off firing. The internet tells me that it has to prime the oil nozzle (wasting fuel), reheat bits of the boiler that have cooled (wasting fuel) and even that the flame takes time to stabilise (wasting fuel). I can understand that all these things *might* be...

@oilhead It is a delicate balance. Thanks, in fact I've fiddled with the pump settings. None make a difference to the short cycling issue and what its on now (PP3, its a Grundfoss magna) seems to keep the return as low as possible most of the time. What you comment about thermostats is...

@oilhead Client (ie me) with a bigger is better mentality. Though I'd question whether its oversized (notional radiator size totals to 31kw, we've 2 unvented cyclinders and we're adding around 6kw of extra radiators to improve the heat up time of two rooms). The boiler does burn...

In response to the OP. I've got cross climates on an Audi A3 Quattro. They're a little noisier than average and are maybe a tiny bit less precise than Continental Sport Contacts. They seem nearly as good in snow as full winters (Kumhos in my case) and don't kill the handling (the Kumhos were...

I have a Grant Vortex 36/46. Its derated to about 32kw but even so in normal weather it spends its time bouncing off the boiler stat, burning for about 2 mins, off for 2 mins, burning for 2 mins etc (I've got temperature loggers on the flow and return). Even with a modulating pump the return...

Either Tado or Evohome will do what you want on the control side. Any TRV/zone of TRVs can call for heat. In the absence of any TRVs calling for heat the boiler is off. I would say that you need a bypass circuit to handle any pump overrun or leave one radiator/towel rail uncontrolled and...
