On comparing the performance of radiators with the heat throughput expected of the steel/plastic/copper structure it appears that, even though steel is 200 times better than plastic the heat loss by convection is still, by 10*, the major restriction. Consequently it should be fine to use the plastic grid as an external radiator for summer re-heating, subject to its uv resistance.
Of course we had a new meter installed as part of a change to 3-phase, and the installer described it as 'smart', though the suppliers (also eon) subsequently denied this. It appears, however, that the installer was correct and this meter is now described on the website (if one checks this specific installation) as 'able to be read using sms'. Photos clearly show that this is right. On the other hand the system of (e-mail) requested meter reads and occasional calling readers is still in place, and no remote reading is actually happening. The offered website 'energy tracker' just uses this monthly data. In fact the meter reading person has not even (on the second attempt) absorbed the idea that the meter is now in a box outside the house and he just leaves the usual card instead!
Note added 1/3/11
The meter was read by the meter man yesterday when we were out, but it appears that he inverted the day/night readings. So we have given two more (sets of) readings today which apparently allows this to be corrected. The meter does give 8 readings altogether, possibly associated with the potential ability to feed-in power.
