The Joule 25-year warranty covers Joule cylinders installed in domestic properties against corrosion for a period of 25 years from the date of purchase on mains water supply.

The Joule 10-year warranty covers Joule Wellmaster cylinders installed in domestic properties against corrosion for a period of 10 years from date of purchase. Wellmaster cylinders must be maintained annually and the sacrificial anode changed on the annual service to maintain this warranty period.

All other components, including valves, expansion vessels, immersion heaters, fittings, and controls are covered by a two year warranty.

Joule does not offer a service for annual maintenance on any heating systems. Service and maintenance can be carried out by any qualified plumber/engineer. Proof of annual service will be required for any warranty call outs. Service should be carried out to the standard provided in the install manual.

Annual Maintenance

General

Servicing should only be carried out by competent installers and any spare parts used must be purchased from Joule.

Draining

Switch the electrical power off (important to avoid damage to element). Isolate boiler from the unit. Turn off the cold water supply valve. Open hot water tap. Open the drain valve. The unit will drain.

Annual Maintenance

The water heaters require annual servicing in order to ensure safe working and optimum performance. It is essential that the following checks are performed by a competent installer on an annual basis. This is commonly done at the same time as the annual boiler service.

• Twist the cap of the expansion relief valve on the inlet control set and allow water to flow for 5 seconds. Release and make sure it resets correctly.
• Repeat with the pressure / temperature relief valve. In both cases check that the discharge pipework is carrying the water away adequately. If not, check for blockages etc. and clear.
• Check that any immersion heaters fitted are working correctly and that they are controlling the water at a temperature between 55°C and 65°C.
• Check the pressure in the expansion vessel is charged to 3 bar. Turn off the water supply to the unit and open a hot tap first. The air valve on expansion vessel is a Schrader (car tyre) type.
• Air or CO2 may be used to charge the expansion vessel. Unscrew the head on the inlet control set and clean the mesh filter within.

The Service Log Book supplied with this unit should be updated at each service.

Immersion Heater Replacement

If the thermal cut out on the Immersion heater operates contact a competent installer. If the thermal cut out fault occurs again the immersion will need to be replaced. Prior to installing the replacement Immersion, ensure the o-ring is correctly positioned on the head of the Immersion and lubricate the threads before fitting.

Thread the Immersion by hand until it is hand tight and then tighten gently to allow the o-rings to create a water tight seal.

Inspection

Where internal inspection of the cylinder is required an endoscope can be used. Inspection can be carried out by draining down the cylinder and removing a component that is fitted to a wet connection in the cylinder.

Safety Valve Checks

Water discharges from either the temperature/pressure relief valve or the expansion relief valve indicates a problem.

• Check your discharge pipework is free from debris and is carrying water away to waste effectively.
• Next hold both of these safety valves open, allowing as much water as possible to flow through the tundish.
• Release the valves and check that they reseat correctly.
