Maybe best logging site ever? Fujitsu ASHP waterstage data loggings from Nederland and Belgium:

Looking through the systems on optics link there appears to be a large variation in the Delta T on the ground loops or bore holes. I thought this should normally be around 3c or have I got this wrong?

Thank you both for interesting links Cheesy

This is a similar version run by Mitsubishi in the  UK http://domesticheating.mitsubishielectric.co.uk/ecodan_dashboard

Like the dashboard (would like it even more if it was independent of Mitsubishi)

Shame there are not more than the four linked up.............. onpatrol

"We understand that air source heat pumps are still new to a lot of people and this dashboard is designed to be as open and transparent as possible so that homeowners can see the results for themselves, whether it is in the height of the summer or in the depths of the winter.

The dashboard currently gives an overview of four properties:

3-bed semi-detached home in Bedfordshire, built in 2008

3-bed semi-detached home in Hertfordshire, built in 1955

4-bed detached home in Bedfordshire built in 2000

5-bed detached home in Northumberland, built in 1999"

You got it right. There is a large consensus that 3 degree is the one to aim with. Smaller Delta T means extra consumption for ground loop pump, which don't cover slightly increased COP.

some of those temp sensors seem to be cross wired the return is higher than the feed.

the mitsubishi systems seem to work very well, they have flow temps of 30-40 degrees and state they have rads. must be big if it's to MIS 3005.

I got sent a questionaire by Mits for my EcoDan. Still waiting to hear if my system will be chosen to go on this site...

On another note, I also had to fill out a questionaire for the RHI folk to monitor my system but was declined...

Quite happy as they don't cover the leccy costs for the remote monitoring system  Wink
