Justin installed a 60 tube system for Phil Redman on a new build. The
system comprised
2 x 30 Tube 58mm collector panels
1 x D2F twin line Resol Pumping Station
1 X Resol ES controller
1 x 250 litre triple coil vented cylinder
1 x Resol 3 port valve
1 x thermostatically controlled mixing valve
Phil's house has a roof ridge line that runs North to South. This system
is unusual because it is mounted both on a West and an East facing roof. When the sun
rises in the East the panel on the East facing roof operates. By mid day
both panels on the roofs are operating due to the
position of the sun. In the afternoon when the sun is in the West the 'West' facing
panel operates. The twin pump pumping station splits the solar loop
between the two collectors, and can circulate fluid through either or both
panels, as determined by sensors in both panels,
With the triple coil hot water cylinder and Resol ES controller, a sophisticated
system is possible in which the solar first heats water at the top of the
cylinder, in order to heat a small quantity of water quickly, then switches to
heat the lower part of the cylinder.
Justin also installed 350 metres of underfloor heating and manifold which are
currently heated by an Amptec 9KW electric heater using 'Off Peak'
electricity. A wood burner has also been installed in the property.
Thanks to Justin and Phil for this information.
