The EasyFlow annual service for unvented water heaters includes testing safety valves, recharging pressure vessels, cleaning the pressure reduction valve, checking electrical connections and providing a service certificate. We also offer a Maintenance Plan which includes a free annual service, call outs to investigate faults, and parts and labour for repairs in return for a low monthly fee paid for by direct debit.

Manufacturers of unvented water heaters recommend that you have your water heater serviced once each year, and many home insurance policies require this. Note that failure to ensure that your hot water heater and the pipework are inspected and maintained each year can result in failure to cover damage if something were to occur. 

Annual maintenance will help to keep the water heater safe and in line with the requirements of the G3 building regulations relating to hot water systems. Details of what is included in the annual service are shown below.

Other types of water heaters such as thermal store or combination water heaters are not required to have an annual service. For these water heaters, we offer a ‘system health check’, which enables us to investigate all aspects of the heater and provide a report showing the condition of the water heater and enables you to keep on top of maintenance.

Unvented water heaters are safe to use if installed and maintained correctly though an annual service. They incorporate three levels of safety. Thermostats that prevent the water being heated above 60 – 65°, high level cut-outs that operate when water reaches 80 – 85° because the thermostat has failed and a temperature relief valve, which operates if both of the other safety features fail and the water reaches 90 – 95°. In addition unvented water systems also incorporate a pressure relief valve which operates at 6 – 7 bar.

If these safety features are missing or have become faulty then there is a risk that the water will overheat and pressure will build up in the tank.

The following tasks will be completed during the annual package of your unvented water heater and hot water heater maintenance, repair and service:

• Expansion relief valve testing
• Temperature and pressure relief valve testing
• Combination valve/pressure reduction valve stripping and line strainer cleaning
• Pressure expansion vessel check (if so equipped)
• Expansion vessel pressure top up
• Leak check
• Main and boost immersion heater and thermostat function testing
• Main and boost immersion heater resistance check
• Check to ensure the appliance is earthed
• Service record completion and signing

As you can see from the information above, we offer one of the most comprehensive service packages on the market, designed to help ensure that you enjoy convenience and safety at all times with the unvented hot water heater in your home.

Note: The replacement of sacraficial annodes is not included in an annual service. If the sacrificial annodes do need to be replaced, this will be quoted for seperately. The majority of water heaters do not have sacrificial annodes. Owners of Ariston water heaters should be aware of this point.

EasyFlow operates an annual service register to remind you to have your unvented water heater serviced and hot water heater maintenance performed each year. We will send you a reminder card when your water heater repair service is due, and will follow this up with a phone call to book the service appointment.

Over the many years we’ve been in business, we’ve found that our customers can forget about their unvented hot water heater maintenance. We created our annual service register to help make the process simpler. We provide you with a reminder about your service, and allow you the flexibility of confirming a default appointment, or of choosing your own date for hot water heater maintenance and/or service.

We will provide you with a service log book if you have misplaced your installation / service logbook given to you by the original installer. We will also keep a record of the service history on file should you need it.

Both of these are critical considerations. Without an accurate log of what services have been performed, there is no proof that you’ve followed the law in regards to annual service. In addition, without a record of services, repairs and maintenance, there is no record of the parts that have been replaced, the problems that have been solved, or troubleshooting that has taken place. This information is vital to ensuring speedy repairs and accurate maintenance moving forward.

We’ve mentioned our maintenance plans several times thus far, and it’s important that we take a moment and explain why they matter so much. Why should you be considered with the maintenance of your unvented hot water heater? Actually, there are several different reasons.

Without ongoing maintenance and protection, it’s possible that your unvented hot water heater will break down eventually. This could leave you without any hot water at a critical time. It could also lead to serious safety issues, particularly if there is a failure of internal components, or if a problem occurs with the connection to the electrical system within your home.

Annual maintenance from EasyFlow will help ensure that you never need to worry about being inconvenienced and without hot water, or subject to safety concerns.
