If you have a system made by another manufacturer and finding it difficult to find parts or you need a service, we at Energycraft have the skill and expertise to service and maintain all types of systems. We recommend regular maintenace of your system particularly with well water. We supply and insert an Anode into the cylinder. This should be monitored at regular intervals and replaced when required. This is a simple enough process to undertake. Our evacuated tubes don't really require any attention, just ensure no debris is covering or has damaged the sytem on the roof. The glycol liquid that circulates within the system, will probably need replacing in 6-8 years, again this is a straightforward procedure. If you require a maintenance call, please phone Energycraft today.
