Smart Maintenance: How a Simple Tundish Check Can Prevent Major Expenses 23 Oct 2025 Your unvented hot water cylinder has several safety features. One of the most visible (but least understood by UK homeowners) is the tundish. This small fitting sits in the discharge pipework between the cylinder’s safety valves and the drain. Its job? To give you a clear view of whether water is escaping from the system. It’s a low-tech part, but its job is pretty important. Checking it regularly could save you hundreds, if not thousands, in repair bills. Why the Tundish Matters Normally, your tundish should be dry. It only carries water if a pressure relief valve or temperature relief… Read more
Smart Controls & IoT for Hot Water: Save Energy, Avoid Cold Showers 15 Oct 2025 Heating your hot water shouldn’t be guesswork. However, in many homes, the hot water cylinder runs on a fixed timer, heating the same amount every day, whether you need it or not. That equals wasted energy and higher bills or, worse, running out of hot water when you need it most. Modern smart controls and IoT (Internet of Things) technology can help you avoid that fate. They give you control over your hot water supply, improve efficiency, cut waste, and make cold showers a thing of the past. How Smart Hot Water Controls Work Smart controls replace or integrate with… Read more
Signs Your Hot Water Cylinder is Working Too Hard (and Wasting Your Money) 7 Oct 2025 Your unvented hot water cylinder is designed to deliver hot water reliably and efficiently. But like any system, it has limits. When it’s overworked, there could be subtle (or not-so-subtle) signs that it’s struggling. Not acting now can push up energy bills, shorten the lifespan of your cylinder, and even leave you without hot water when you need it most. Here’s how to spot an overworked system and what you can do about it. 1. Hot Water Cylinder Running Constantly If your cylinder seems to be heating all the time, even when you’re not using much hot water, it’s a… Read more
How Hard Water Silently Damages Your Unvented Cylinder (and What to Do About It) 30 Sep 2025 If you live in a hard water area (which is much of the UK), you already know about kettle scale and cloudy glassware. However, what you might not realise is that the same mineral build-up is quietly forming inside your hot water system, and fixing that is far more expensive than replacing a kettle. Your unvented cylinder is designed for reliability and efficiency, but limescale will slowly and silently destroy it. Over time, lime deposits reduce performance, waste energy, and could even leave you facing a “no hot water” emergency. Why Hard Water Is a Problem Hard water is rich… Read more
Energy Efficiency Hacks for Unvented Cylinder Owners 25 Sep 2025 Your unvented hot water cylinder is built to deliver strong, consistent water pressure and to refill and reheat fast. However, like any system, its efficiency depends on how well you maintain it. A perfectly functioning cylinder heats water with very little waste. One that isn’t maintained can quietly drain your wallet through higher energy bills, wasted water, and premature wear. The good news is that a few smart habits and simple checks can keep your system running at peak efficiency and save you money. Keep Your Combination Valve Clean and Healthy The combination valve regulates incoming water pressure, prevents backflow,… Read more
Annual Service vs. Emergency Repair: The Real ROI for Unvented Cylinders 9 Sep 2025 There are two ways to spend money when it comes to your unvented hot water cylinder: a little each year on routine servicing, or a lot all at once when something goes wrong. The choice might seem obvious, and yet many homeowners only call an engineer when the taps run cold. The truth is that waiting for a breakdown can cost you far more than a regular annual service, not just in pounds, but in stress, disruption, and even wasted energy. The Cost of an Emergency Repair If your unvented cylinder fails unexpectedly, you’re looking at: Higher call-out fees, especially… Read more

Is It Cheaper to Use a Timer for Your Hot Water Cylinder? 18 Jul 2025 If you’ve ever opened your energy bill and thought, “Where’s all this going?”, hot water is likely a big part of the answer. In many UK homes, the hot water cylinder is one of the most energy-hungry appliances. But is keeping it running all day necessary? Or can a timer help reduce your bills without leaving you with cold showers? We’ll explore what you need to know in this blog post. What a Hot Water Timer Actually Does A hot water timer controls when your immersion heater or boiler heats the water stored in your cylinder. Instead of running constantly,… Read more
How to Tell If Your Hot Water Cylinder Needs Replacing 11 Jul 2025 Hot water cylinders don’t last forever. They’re also a big expense. So, how do you know when yours is on the way out and how do you tell the difference between impending doom and a repairable problem? Failing hot water cylinders often gives warning signs before the issues become real trouble. Ignoring those signs can mean dealing with poor efficiency, rising bills, or even water damage in your home. The good news is that if you know what to look for, you can spot minor issues before one becomes a problem and decide whether to repair or replace the cylinder.… Read more
What to Look for in a High-Quality, High-Efficiency Unvented Cylinder 4 Jun 2025 Want high-pressure hot water at every tap in your home? It’s time to get rid of your old, vented cylinder and invest in an unvented cylinder. Unvented cylinders deliver mains-pressure hot water on demand, making sure you have comfortable showers, plenty of pressure and heat for washing up after a meal, and more. However, if you’re buying a new unvented cylinder, it’s important to realize that they’re not all created equal. If you’re making this investment, you want the best.
