Hard Water in Hot Water Systems Background
The continent of Australia often experiences drought conditions somewhere in the country at any one time. The city of Perth has 26 different sources of water supply, and when the water resources are low more water is pumped from deep underground wells known as bores. In recent years concerns and problems grew to such an extent that in Perth a task force was set up by the plumbing industry to help advise the state government’s water board of problems created by the poor quality hard water and diminishing water supplies.
New artesian water bores were drilled to keep up with water demand and were dragging up corrosive & high sediment water which has caused many problems including:
warranty claims on valve manufacturers due to clogged and corroded valves
plumbing suppliers warranty claims for pitted copper tubing and fittings
warranty claims on hot-water manufacturers due to heating element pitting and resulting failure
warranty claims on hot-water manufacturers due to calcium encrustation causing premature failure.
Dealing with the Problem
R. Edmonds & Sons are an Australian company that design, manufacture and sell Edson water heaters. They hold national contracts for design and supply of commercial hot water systems for many national corporations.
During the severe droughts in Western Australia many areas began experiencing very heavy, extreme, calcium scaling which coated heating elements and caused them to fail after only a few weeks of operation. When calcium scale builds up on heating elements it prevents the heat from being transferred to the surrounding water. This in turn causes premature burnout and complete failure of heating elements.
A local Edson contractor, who had had a Softer Water Conditioner in his own home for 7 years, recommended a unit be installed in the water heater system. So to overcome the problem the Softer Water Conditioners were installed.
After continuing inspections it has been proven that the Softer Water Conditioners have overcome the problem. In fact, the Edson stainless steel hot water system has been operational at one location for the past 11 years without the need to change the heating element at all during this time.
John Mangan, the Operations Manager of Edson Hot Water Systems was thrilled with the results they have had. “Coles have specified the Softer Water Conditioners anti-scale system be installed on all new hot water system installations in Western Australia, coastal and known hard water areas. So we have installed numerous Edson Hot Water Systems with Softer Water Conditioners in a number of known hard water areas with fantastic results. We now offer them as a standard option to all who are purchasing an Edson Hot Water System, commercial or domestic.”
