remember it's a split, doesn't make things easier...

Good thing you didn't buy it then!

do you have an accumulator?

the default setup on my ASHP was return temp too, but "return" in this case is a wandering probe that could instead be in a buffer tank. I've now re-set it to flow to try. Power consumption seems very similar in both modes. In both cases my external probes tell me that return temp pretty much matches the circulating temp in the slab, but the delta and pump speed control are radically different. Tis velly interresting. I'm waiting for a flow-setter coming so I can get the pump speed best optimised. It's PWM but the limits are adjustable, plus I've got a secondary in the plant room too.

they do a kit with various fittings too or you can bodge one but a glycerine filled gauge is better, yes. Danfoss pumps are 1/8"BSP yes but I've no idea what the Riello is- the pressure gauge screws into the hole at the top of the long hex extension IIRC?

Nope, the nozzle presure will be something between 100 and 150psi.

the meter is on the "wrong" side of the Solic to my mind. But that doesn't account for a near-3kW load mysteriously turning on...

something's turning the immersion on still, I fear...

or the motor, or the control box... /hate Riello, sorry...

"a pump for RDB2 please" from your local knowledgeable wholesaler... Still no guarantee it's the pump, could be the solenoid going O/C and I don't think the pumps come with a new coil?

and? any updates? Chris seems pretty knowledgeable.

so what (in numbers) *is* the humidity in *any* part of your house, or outside it for that matter?

all our battening is 35x50

no , set to depressurise. easy to feel draughts then...

so the plastic case is directly on the wall then, the top hangers aren't isolated IIRC. Need to rubber-isolate the hanging points or maybe build a shelf and set it on it, over a rubber layer.

PUT A HEATER IN THE ROOM FFS!!!!!!!!!!!!!!!!!!!

I "feel" you still gotta read up on dewpoints and condensing surfaces.

I just went with their cheapest blue stuff and couldn't fault it, tbh.

honestly Clive it's so internittent we're clutching at straws. Pump/ control box/ tiny air leak in the oil line that builds up to a big airlocking bubble? All possible...

both diesel and 2T are designed to be burned and do so with as little residue as possible. 2T is formulated to disperse in the base to lubricate, diesel's additives protect sensitive injection equipment at speeds and loads far in excess of your burner's capabilities. Engine oil, unless it's one of the latest formulations for cars with Particle filters creates a fair bit of metallic ash when burnt...

not all. Half-ish

that'll do. Lash it in with plenty of splashing, it'll mix OK

possibly, but check for an imbalance issue- loose or missing balance weight, debris in the fan. Most rotating objects go through an imbalance period but smooth out past that speed, any looseness in the bearings may exacerbate it .

I found there's quite a big difference between the bigger firms like K2 and Aztech, and the smaller local crews. I can PM you a phone number for our guy if you want.

not quite. Mechanical stats had a resistor in them that heated the bimetal to get it to switch slightly ahead of time. Today's programmable stats have all sorts of rate-of-rise fuzzyness in, and turn off slightly below setpoint as they know there'll be a bit more heat added after the boiler is cut out.
