Ecocat Thermal Store Cylinder Sizing Guide
At Chelmer, our thermal store cylinders form the heart of our systems. Acting as a central hub for heating and hot water, they allow the integration of multiple heat sources (i.e. boiler, solar thermal and a stove) into a single system.
The guides below should give you an idea of which of our thermal stores is suitable for your project. To enable us to accurately specify the correct cylinder for your particular application, please submit your project plans and requirements for a free quotation.
