Replied to the topic Is Traditional Radiator Balancing Tosh?

@markspencersmith Before I offer my thoughts I am not sure I understand what you are saying in the above quote. Can you clarify the last part 'WC is decreased' (why and by what mechanism)? Can I also ask if the 'guy you spoke to' has tried this and what the result was, or is this currently ...

I'm trying to control my Grant Areona 3 with modbus, I can read everything but can't write to it. Every write reverts. Did you have this problem, was there a setting change I need to do to release a lock-control on it first?

Created the topic Is Traditional Radiator Balancing Tosh? in Air Source Heat Pumps (ASHPs)

So, conventional HP wisdom says to balance the rads by dT or dflow as a proxy per the rad size and required output. As a physics guy this seem to be putting the conclusion ahead of the measurement. If the heat demand was perfectly static and mapped to the WC curve exactly then great, but the real ...

Replied to the topic Peak Energy Products V therm 16kW unit heat pump not reaching flow temperature

As a final update on this thread from me; Ribble Valley completed the Grant 12KW ASHP installation on Friday, and now I can see and appreciate the efficient, quiet and warm aspects of an ASHP! The house feels warm throughout and the temperature is maintained, what a wonderful thing working weather...

My local council (Highland Council) advised me to ask local heat pump installers how they deal with it. None has replied.

In London we have a free hazardous waste collection service. I assume all areas have the equivalent.

@seoras that's genuinely frustrating, and you're not alone in that experience. The disposal infrastructure for glycol from domestic heating systems is woeful... it's one of those areas where the industry has pushed a product into hundreds of thousands of homes without thinking through the end-of-lif...

Which level of council did you speak to? District and Borough Councils have responsibility for Environmental Health and domestic refuse collection. Country Councils and Unitary Authorities also have Environment Health, together with recycling centres, trading standards etc. They also appoint rep...

Replied to the topic New Vaillant aroTherm Plus in black - When will it come to the UK?

Fantastic. This is all I needed. Afew planning applications from the neighbour confirmed no opening windows on living spaces facing us. So the only thing restricting siting of an R290 would be the exclusion zones. But even before the Vaillant anthracite arotherm, it will be straightforward to site...
