Our Solar Hot Water Cylinders are specifically designed to work in conjunction with the domestic heating system. These solar cylinders are manufactured with either two or three independent coils. One or two to transfer heat from an independent heating source, (e.g. central heating boiler or solid fuel). The other, which is manufactured from high efficency finned tube with a high heating surface, to transfer heat from the solar thermal panels. The boiler coil which (if fitted) is manufactured to BS 1566 and can be fitted with 28mm compression connections or 22mm compression connections. The high efficiency solar hot water coil can be fitted with 22mm compression or 15mm compression fittings. We normally fit 22mm compression fittings to the heating coils and 15mm compression fittings to the solar coil. Our solar cylinders are manufactured to our own designs, and we can make up custom cylinders to customer specifications.
