Water Heater Maintenance: Does an Electric Boiler Need Maintenance?

Water Heater Maintenance: Does an Electric Boiler Need Maintenance? Gas heat is used throughout much of the UK. However, there are millions of homes that are not connected to the gas network that still need hot water and heat. Electric boilers offer a viable solution there, providing plenty of performance, reliability, and decent energy savings. However, like any other appliance, there are care and maintenance considerations that you’ll need to make with an electric boiler. Do You Really Need to Maintain Them Annually? The simple answer here is “yes”. You should have your electric boiler inspected and serviced every year. The reason for this is that unvented cylinders, while offering better performance and reliability than vented cylinders, do have inherent risks. They are pressurised metal cylinders. If one or both of the safety systems were to fail, it could be very dangerous. Annual inspections and maintenance ensure that your cylinder does not become an explosion hazard. What’s Required in Terms of Annual Maintenance? If you have used gas or oil boilers in the past, you will be pleasantly surprised by how little an electric boiler requires in the way of maintenance. There are no specific annual replacements needed, the way there are with other types of boilers. Instead, you really only need a visual inspection of the boiler and the associated systems – including the pressure relief valve and the temperature relief valve. Both of these must be in good working condition for an unvented cylinder to be safe. Additionally, a qualified plumber will also check a number of other things on your boiler. These include the following: Checking all electrical connections to ensure tightness and that there is no corrosion Checking the tundish and surrounding area for signs of water Checking for signs of damage to wiring, such as rodent gnawing, etc. Check the air bubble in the cylinder tank Check the thermostat for functionality/wear Additionally, there is a need to drain water heater cylinders periodically. The reason for this is build-up from sediment/debris/minerals within the water itself. For instance, a water supply high in lime will create limescale build-up within the cylinder through normal use. Over time, this build-up can become quite substantial, compromising the performance of the cylinder. By draining the cylinder annually, much of that build-up can be removed. This prolongs the lifespan of your cylinder and improves its performance when factored over time. As you can see, while there is not a lot involved with annual maintenance, it is important that you have it performed. It’s also important that you only work with a G3 qualified plumber. They are the only professionals licensed in the UK to service unvented cylinders (this doesn’t apply if you have a vented cylinder). At EasyFlow, our professional plumbers are all G3 qualified and capable of providing the maintenance that you need. It’s never been easier to ensure that you and your family have access to a constant flow of hot water. Call us on 0161 941 5571 today to schedule an appointment.

Understanding Your Water Heater: How Do Unvented Cylinders Work?

Today, there are two types of water heaters used in residential applications. One type is older and has been around for a long time – vented cylinders. The other – an unvented cylinder – has been in use for several decades, but still represents newer technology and is harder for consumers to understand. At Easy Flow, our goal is to help our customers understand the systems and appliances installed within their home, including unvented cylinders. The Basics of Unvented Cylinder Operation Unvented cylinders are connected directly to your mains water supply. That ensures there is plenty of pressure when you open the tap, and it is heated using either a series of electric heating elements within the cylinder, or via a boiler. Because of the design, there is no need for a cold-water storage/feeder tank, and no need to install it high up within the home. That frees up plumbing space, plus offers additional room for other things you might want. The Expansion Tank While an unvented cylinder does not need a cold-water storage/feeder tank, it does need what’s called an expansion vessel. Basically, water expands when it is heated. Because the cylinder is not vented, there must be somewhere for the excess water to go when it is heated. The expansion vessel is usually installed on top of the cylinder itself and serves this purpose. As the water expands, it moves into the expansion tank. When it cools, it flows back into the body of the cylinder itself. The tank should be inspected annually for safety. Air Bubble Expansion Some unvented cylinders use a different expansion method. Rather than an external expansion tank, they use an internal air bubble. In this situation, air is trapped within the cylinder itself. As the water heats and expands, the bubble becomes compressed, providing additional space for heated water. Like the expansion tank, your internal air bubble should be maintained annually to ensure safe operation. Ensuring Safety Vented cylinders allow all the pressure that builds up as a result of heating water to escape into the atmosphere. Unvented cylinders do not. Because of that, they have several safety systems installed. The first is a temperature relief valve that activates if the unit were to overheat and allows excess heat and steam to be vented safely. The second is a pressure relief valve that activates if the pressure reducing valve on the inflow side were to fail. Who Should Install Unvented Cylinders? Unvented cylinders offer excellent performance and better pressure in showers and at the taps throughout your home. However, they should never be installed by amateurs. In fact, only plumbers licensed to install unvented cylinders should be allowed to work in your home. A qualified plumber understands how to install unvented cylinders safely and quickly, and can also provide annual inspections to ensure ongoing safe operation of your hot water system. At EasyFlow, our engineers are fully trained and qualified to install unvented cylinders. Call us on 0161 941 5571.
