The requirement is to install a Solar Hot Water system capable of providing domestic hot water for a 300 litre tank. The existing tank is a Ultra Steel manufactured by RCM Group. It is a non-vented system and already has a secondary coil. The Visseman 200 gas central heating is currently plumbed into this secondary coil.

There is the possibility of installing a wood burning stove that would provide heat in winter. The solution would need to account for additional heating option coming from the this back boiler.
