There are 2 phases to the install.

!st:
The primary system is going in around 15 th January. This is the
District heating station.
It will save me abouit 45% on hot water.

2nd
The solar collectors are about 65% cheaper when ordered direct from
China. They Have passed the Solar Key mark standard required for
European standards, and are supported by Boverket, so i get about 50%
back from the governenrment too.
I will put in 300 litres of accumulators. These are dirty cheap as
they are ONLY accumulators.
The solar collectors and accumulators will go in as soon as the
fucking snow clears :)

This will save about 25% again. This is high because we use ALOT of
hot water. I expect a 3 year pay back, instead of the normal 6.

The hook up between the District heating station and the accumulators
requires a custom control system.
I am still looking around for valve actuators that can do this.
The controller hookup between the accumulator and the solar collectors
can be the standard one. Nothing custom here.
