better not forget the locking collets on the JG fitting if it's going to be unseen...

depends. ASHP tops the tank up- and catches better half's morning shower- during the E7 period in winter. Currently the PV is diverting to it.

11p/ day here.

Depends on the standing charge surely?

Fan? if you're savvy electronically, you might open it up and see if you can ascertain the offending board area or component; a blob of silicone might well damp the culprit.

why do you think you need 4-core to a boost switch? It only needs to be a momentary contact closure.

230kg sounds like an awful lot, is this a Conder with a steel frame underneath? I don't think our Solido would've been over 100kg. We used out 2.7t machine to install it, but there's no way it would've had the reach to lift it off a wagon.

well 70 is already scalding temperature so you should be able to confirm a tempering valve on your hot tank? If so then yes, it's safe.

so during the day they won't notice the light and it will burn needlessly. The corner of a shelf in the hips/ ribs OTOH might just focus the mind...

nope, that's just an overflow tank to catch anything from the safety valve.

Look at LBS Snowdon. Slate-looking clay tile. Great job...

...but hang on, you say it's a drainback system? Are there any valves that have erroneously been shut off that might be restricting that?

I wouldn't expect it to immediately start doing things if it's already at elevated temperatures. Change the settings and monitor it tomorrow on heat-up.

At 70c you must have a tempering valve on your tank to protect users, so why not just increase store temp to 80c or more? Is this a drainback system? How many sensors are connected? what is the setting for EM, collector limit?

my reply was aimed at @saveasteading, sorry. Have you been charged for the engineer's time, designing the plant in the wrong place?

I'm not talking about in industry or commercial development. Looking at the size of a house to size a treatment plant aint rocket science?

As @JohnMo says, Beam will flog you something in a very retail manner. Personally I went BPC for design and hardware, but acquired the main unit off Ebay and bought everything else from them. I self-installed...

why is a SE speccing something non-structural?

@nod are all the internals in your own house MF?

so given that anyone can at any time add a diverter and start making savings, how does one start- at any time- to receive payment for export with a self-installed non-MCS PV system?

that looks like a bi-metal weld that's failed, or maybe it's even just a swaged and pressed joint and a crack formed at the top of the swage?

if it's oversized a bit you can throttle both flow and pressure. Inefficient yes, but you can do it if you need to.

this. a car will charge off a 13A outside socket...

Compriband of the right height instead?

all our controls and the secondary pump come off a different supply. Even if the ASHP was to expire and need to be isolated, we can heat the whole house either by immersion or boiler stove. Indeed even during a power failure everything bar the immersion can happily run off an inverter if needs be.
