My SES (Solar Hot Water) system does not improve the BER

First check that your building has sufficient hot water demand to make the incorporation of a solar hot water system worthwhile.

Also, the solar characteristics need to be carefully set. Forced circulation will increase the auxiliary contribution and additional hot water storage (for the combined cylinder case the solar storage increases the total storage of the cylinder) will increase the storage heat losses.
