The Most Common Repairs for Unvented Cylinders

Unvented cylinders offer a lot of benefits over older vented technology. They can be installed almost anywhere around your home. They don’t make a lot of noise. They provide mains pressure hot water at all the taps in the house or apartment. However, like all other appliances, they are subject to wear and tear. It’s important to know some of the most common repairs that you might need on your cylinder. Immersion Heater Replacement One of the most common issues we see at EasyFlow is immersion heater failure. All unvented cylinders have at least one immersion heater, but most have two (or more). These heaters are responsible for warming the water to the specified temperature. If a heater fails, it will take longer for the water to warm up, and it may never reach the correct temperature in some instances. Replacing an immersion heater is not something that the average homeowner should undertake – working with a trusted professional like an EasyFlow technician is the best option. Thermostat Replacement Your unvented cylinder’s thermostat is responsible for setting and maintaining water temperature. You can choose the temperature that works best for your needs and that’s safe for protection against bacteria, as well. However, thermostats can and do fail. A simple way to test yours is to adjust the thermostat up and see if the temperature of the water increases. If it does, then the thermostat is not a problem. It’s best to let a professional handle your thermostat replacement if the unit fails, though. Pressure Relief Valve The pressure relief valve is a safety device designed to help ensure that your unvented cylinder does not become over pressurised. When the internal pressure rises too high, the valve opens, allowing the excess to escape. However, if the valve fails, it will not function correctly. In most cases, it will fail open, allowing pressure to escape. You will usually notice this in a reduction of pressure and heat in the water at your taps. Pressure Reducing Valve A pressure reducing valve is installed on the inlet line to ensure that the water pressure coming into the cylinder is at a safe level. Failure of the valve could mean no water entering the cylinder or it could allow high-pressure water in, which could damage the cylinder itself. The Solution While unvented cylinders are reliable and efficient, they can suffer from wear and tear. Any of the situations we discussed in this post could leave you with no hot water. What’s the best way to make sure that you’re not stuck in that position? The answer is annual service through a professional partner like EasyFlow. We offer affordable annual service/maintenance plans that include a full inspection of components that are likely to fail, as well as the rest of the cylinder. Regular maintenance is the best way to ensure that you’re not caught unprepared. Our technicians carry most parts on their trucks, too, so if a part is failing (or has already failed), replacing it is a simple matter.

Thermal Store Cylinder FAQs

So, you’re thinking about investing in a thermal store cylinder instead of an unvented cylinder. Thermal stores can offer a lot of utility and flexibility, but they’re very different from what you might be used to in terms of water heating capabilities and how they work. In this post, we want to address some of the most common thermal store cylinder questions. How do thermal stores heat water? With an unvented cylinder, water is heated either through an immersion heater (electric) or through gas firing. Both of these are direct heating methods. Thermal store cylinders, on the other hand, heat water indirectly. The cylinder itself holds water that gets heated but is never sent to the taps. Instead, it’s directed through a series of pipes and into a heat exchanger. Water from the mains also through past the heat exchanger (without contacting the water from the cylinder). The heat built up in the heat exchanger warms that water, which then flows to the taps, giving you hot water for washing dishes or bathing. What advantages do thermal store cylinders offer? You’ll find that thermal store cylinders can offer several important advantages, including: No Stagnant Water – Thermal store cylinders have no stagnant water, which reduces the chance of water contamination with pathogens like the bacteria that cause Legionnaires disease. Versatility – You can use a thermal store cylinder for heating water, but also space heating. No Maintenance – Unlike vented and unvented cylinders, thermal store cylinders do not require annual maintenance. Flexibility – You can connect a thermal store cylinder to many different heat sources, including solar panels, biomass boilers, and more. Can thermal store cylinders work with high mains pressure? Yes, thermal store cylinders can work with pressures of up to 6 bar continuously. They can also withstand 9 bars of peak pressure. With that being said, most manufacturers recommend reducing line pressure to 3.5 bar to prevent line and fitting failure. Can thermal store cylinders work with low mains pressure? Yes and no. The first thing to consider is whether the pressure can be increased. If you live in a flat or shared housing, there may be a pressure limiter that can be adjusted. If you cannot increase the pressure, you will need to either install a loft/attic-located cold tank system with pumps or install a cold storage tank in a lower level with a pump to increase the rate. Where should I install my thermal store cylinder? Thermal store cylinders should be installed no more than 20 metres from the boiler. Other than that, you have a lot of leeway. If you cannot install it closer than that, increase your pipe diameter. Note that heat loss can occur if you install a thermal store cylinder in a cold loft or cellar, so it should be boxed in.

We can discuss your choices and help ensure that you make the right decision.
