Replied to the topic Indevolt Batteries UK Support & Info Thread

Thanks @editor , @indevolt-uk Subject to any comments from @transparent I think we have made some great progress in understanding this issue. Regarding functionality, I note that there is no current transformer/energy meter included in the standard pack but there is reference to an Indevolt energ...

@seoras Sorry to hear that. I found Vaillant very helpful. If, as @editor suggests, you would like to say something about your house, system and what you need help with Im sure we can assist. Plenty of people here (including me) with Vaillant kit

Thanks @indevolt-uk… that’s a really useful clarification, and the 10ms EPS switching figure is the number that I think @jamespa was looking for. To pick up on James’ logic, which I think is sound, any plug-in inverter that shuts down in 10ms is well inside the window that probably matters most he...

Vaillant have been awful for me - offhand, disinterested, lacking technical knowledge - I compare this with how Worcester Bosch were when I had an oil boiler.

Created the topic The Watchdog That Watched and Waited in Government Schemes, Regulations, Training, Planning & Organisations

On 9 January 2026, Consumer Energy Solutions collapsed into administration. It ceased trading with immediate effect, made nearly 300 workers redundant (many of them in Wales, in communities where jobs are scarce) and abandoned thousands of households mid-installation. Solar panels generating electri...

Replied to the topic GSHP Kaput After 16 Years: New Compressor or Switch to ASHP? Advice Welcome

Cool Energy in Grimsby sell ground source heat pumps and they are not expensive. If I were you I'd bung one of them in and simplify your system as mentioned by a previous poster.

Thats arguably a sign of a good installer - they understand that weather compensation is all important and that it may need to be tweaked. There is a very good (but occasionally quite technical) Vaillant forum on heatpumpmonitor.org The guys there have even written up quite lengthy descriptions o...

@jamespa Thanks that’s very helpful. My installer has left room temp mod inactive. The handover comprised two short phone calls so I am still ‘self learning’.

Well, we have so many cases where rain water mixes with sewage.. Seems like even what is supposedly centrally defined is not being addressed. If they did, there would be plenty of extra water suitable for flushing loos.. Anyway, I would not be guinea pig, cannot see how disruption could be avoided! ...

Replied to the topic Two heating zones to one zone

@profzarkov They arent obviously wrong, but the only way to determine the right temperatures is to adjust it (with all zones open, thermostats to max, operated 24x7) until the house temperature is right. They are house dependent and there is now way around that! I would leave 27/16 and if neces...

Replied to the topic Towns water feed to air source heat pump system

The DHW circuit cant be separated (well it could, you could use a plate heat exchanger, but why bother). There needs to be an air bleed at every locally highest point. I guess it might well be possible to plumb a DHW cylinder so it (or some part of its pipework) isnt a locally highest point, but ...
