1960’s HJ Cooper & Sons New Market Cylinder with Hermetic element.

HJ_coopers_and_sonsWhat another great find! This Hj Coopers hot water cylinder (Pressure water heater rated to max head of 25 FT) managed to last over 50 years and was only replaced because of a new home renovation. Otherwise in pretty good shape! In the 60’s hot water cylinders had a higher content of copper. That, the additional material grade and quality manufacturing processes delivered hot water cylinders that lasted decades! What makes this find even more exciting is that the original Guarantee card was still inside the element enclosure, originally signed by the installer and dated 1965. This is museum material right there! Back of the card reads: ” This “Hermetic” element is fully guaranteed for two years from the date of purchase, as shown on other side, against faulty workmanship (this indicates that Hj Coopers used to install the cylinders themselves, whereas today manufactures don’t install and only supply)  or materials, always provided that the element has been subject to fair and reasonable use. The manufacturers will, at their discretion, repair or replace same if returned to them through the dealer from whom the element was purchased , provided the element is accompanied by this card. this guarantee does not cover element whose failure is due to liming or the building up of water impurities. No responsibility is accepted for any consequential damage arising from the use of this element.

After so many years in business HJ coopers have recently been purchased by Rinnai. Whether HJ Coopers will continue to exist as a brand, we don’t know but one thing we do know, this cylinder was certainly a high quality low pressure hot water cylinder in the 60’s! Back to the treasure hunt!
