Reply #7: Rogue traders in every field

[Nihil]

First off, welcome to DU Barry! :hi:

I understand your specific complaint about "zero carbon" as your system
uses a solar-powered electric pump rather than a mains powered one but I'd
like to point out that once the water in the HW tank has been heated, both
systems require mains powered pumps to distribute it around the house ...
It is a selling point for you that should rightly be emphasised in your
adverts but I can see why it was kicked into touch in the context of the
difference in CO2 required between solar *heating* and gas/electric *heating*
of the water.
:shrug:

With regard to the STA, I have also failed to get anywhere with certain
zombie companies that have been active in the South so I can sympathise with
you (and the other honest traders affected).


Could you please provide a little more information on your "Legionella" comments?

Specifically, from your first link:
> FACT – According to UK’s Health Protection Agency, concerning risks from

> from hot water scalding.

I couldn't find anything on this in a quick browse so could you post a link
to such a report? I was wondering if this was due to the lower tank temperatures
found in most (=non-solar) HW systems as they are less likely to have their
thermostat settings higher than about 60C (whereas solar hw systems typically
go to 70C before shutting off and shunting the heat) or whether it was counting
the Legionella risk from A/C units in with the risk from hot water systems?

I had a Thermostatic Mixing Valve fitted last summer due to the scalding risk
(especially for visitors who would be totally unused to anything of that
temperature coming out of the tap) so am happy for the tank to "run hot" now.
I would still like to know how this risk was estimated.

Cheers!
