Buffer Tank Hot when Heating Mode Turned Off

[Dave Jones]

the issue with plumbers is 99% of them have no clue how to system design a ASHPO for efficiency. Any of them can throw a kit together using same principles as a gas boiler. 

 

This is one of the reasons they have such a bad rep.

 

If you see a roomstat anywhere you know for sure its a shit install.

True but inexcusable. 

 

In most professions, indeed most jobs, you need to keep up with developments through ongoing training and, if you can't, or can't be bothered, you risk a performance improvement plan followed, if you don't succeed, by the sack.  Why do plumbers think they are different? 

 

Presumably because, for 20 years, they got away (and are still getting away) with setting up condensing boilers in a way that they don't condense, thus adding 10% to our heating bills.

The use of the word "ideally" rather gives the game away doesn't it? In contractual documents it recognises that the advice following it is not going to be observed by many/most recipients. You could anyway argue that the presence of lockshield valves is "some form of temperature control".

And Vicars, not as if they can change horses mid stream.

 Nest + weather comp for us. Nest gives the wife an easy to use hi-limit (which is only rarely met in shoulder months).

 

I consider myself a good designer/installer.

 

heck, even the Samsung controller when used as a room stat is just that, an on/off stat. It doesn’t do load compensation, despite what people have been led to believe.
