Annual Service Unvented Hot Water Cylinder

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.

Risks associated with unvented systems

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.

Join the Annual Service Register

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.

Ask about our Maintenance Plans

EasyFlow Maintenance Plans offer total peace of mind for a low monthly payment. The Maintenance Plans for unvented water heaters include the cost of an annual service as well as call-outs, parts and labour. Offering great savings, a priority service and no hidden or unexpected costs.

Why Do Maintenance Plans Matter?

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.

Note: If there are faulty parts or if safety valves do not function correctly the plumber will inform you and show you the fault. A quote will be provided for further work as we do not undertake additional work as part of an annual service.

We will not fully drain the cylinder and remove immersion heaters to conduct an internal visual inspection. If this additional service is required, we would be happy to provide a quote for the additional labour and the provision of an internal inspection camera.

Attention: If an unvented water heater has not had a regular annual service there is a possibility that the rubber seals in the safety valves will have hardened. If the seals have hardened, they will not sit back correctly in the valve and will pass water. In this instance water will be visible through the tun-dish in the discharge pipe and the valve in question will need to be replaced. We will provide a quote for the additional work to supply and fit a replacement valve.

In some instances, this may require the replacement of more than one valve, and it may also require the replacement of additional parts and components. Each situation is different, and our experienced technicians will provide a full quote for all parts and labour prior to performing any work to ensure you know precisely what to expect when it comes to serving and maintaining your home’s unvented hot water heater.

Warning: The task of cleaning the line strainer in the pressure reduction valve requires the plumber to remove the cartridge from the body of the valve to gain access to the foil filter. If the unvented water heater has been serviced annually or if the heater is reasonably new this does not usually cause a problem. However in unvented heaters that have not received regular annual services or in older unvented water heaters the rubber seal or spring may have become worn or misshaped. If this has occurred the valve when reassembled may not be water tight. If the valve is not water tight then the main water stop tap will have to be left in the closed position until a replacement pressure reduction valve is installed. This will mean that the water supply is turned off and the client will incur additional expense. We will provide a quote for the additional work to supply and fit a replacement pressure reduction valve. Manufacturers recognised this issue in older valves and changed the general design of the valve body and seals about four years ago.
