Recovery

Electric Storage Water Heaters have a heating recovery which is very close to that of gas storage units. Over 80 litres per hour is delivered with a 50 ° C rise.

Efficiency

Electric Storage Water Heaters require no flueing or burner contact area. Therefore the FULLY insulated cylinders have higher efficiency than gas. Everlast have the further advantage of more efficient storage in a cylinder design giving 50 mm of Urethane Insulation under a fully polymeric casing. The result is the highest thermal efficiency electric storage water heater that is in current manufacture.

Should I specify a single or twin element?

Whether you are a Plumbing Hardware Adviser, a design consultant, a plumber, an architect or a builder - Ask your Customer the following questions :

• Do you have more than one teenager at home?
• Do you intend to fill a spa bath ?
• Do you have any activity or hobby which relies on large volumes of hot water ?
• Was your previous water heater a 400 Litre storage unit ?

If the answer to one or more of these questions is YES, then it is probably advisable to recommend a Twin Element Water Heater.

How do twin and single element water heaters differ?

BOTH single and twin element water heaters have the same recovery capability as they use the same sized elements. Normally, both elements do not operate together. The difference is in the Automatic Recovery of a Twin. A Single Element Water Heater will have a boost button at the meterboard, often incorporated into electronic meters.

Twin Element water heaters have a top element with a thermostat setting which is set 10 - 15 degrees lower than the bottom element thermostat. Because hotter water floats on top of cooler water, the top element will not energise until the water temperature at the top thermostat has dropped substantially. This will only be as a result of high levels of hot water use because the top thermostat is located within the top 50 Litres of the heater. No boost button is required as the boost is Automatic.

The top thermostat will switch off the top element allowing the bottom element to heat at the Off-Peak Tariff. The top thermostat switching function is called Neutral switching
