How often should a water heater be descaled?
Boiler descaling frequency depends heavily on water hardness and usage. A yearly cleaning is sufficient for those with low water hardness, infrequent use, or installed water softening filters. However, for most users, especially in areas with hard water, a biannual cleaning is recommended.
This is because limescale buildup, primarily calcium carbonate, significantly reduces heating efficiency. A thick layer of scale acts as an insulator, forcing the heating element (the heating element, or “ТЭН” as referred to in the original text) to work harder, consuming more energy and potentially leading to premature failure. This translates to higher electricity bills and ultimately, more expensive repairs or replacements.
Here’s a breakdown of factors affecting descaling frequency:
- Water Hardness: Hard water accelerates scale formation. Regular testing can help determine your water’s hardness and inform descaling schedules.
- Usage Frequency: The more frequently your boiler operates, the faster scale accumulates.
- Water Softener: Installing a water softener significantly extends the time between cleanings, making yearly maintenance sufficient for many.
Ignoring descaling can lead to several problems:
- Reduced Efficiency: Increased energy consumption and higher bills.
- Heating Element Damage: Scale buildup can overheat and damage the heating element, necessitating costly repairs or replacement.
- Shorter Lifespan: Constant strain on the boiler reduces its overall lifespan.
- Safety Concerns: Severe scale buildup can potentially lead to overheating and safety hazards.
Regular descaling is a simple preventative measure with significant long-term benefits, ensuring optimal boiler performance and extending its service life. Consider investing in a descaling solution suitable for your boiler type for safe and effective cleaning.

Lower temperatures also reduce energy costs significantly over the lifespan of your water heater—a factor that’s important when considering the total cost of ownership.
Is it safe to leave a water heater on without water?
Never operate a water heater without water. Doing so will instantly fry the heating element (the TEN), rendering it unusable. The lack of water prevents any leaks from occurring, but the element will overheat and likely be ruined due to lack of cooling. Some models, like Thermex, have safety features that shut down the unit when it detects a lack of water, but even then, the heating element will have sustained significant damage—it will be annealed, meaning its structure will be altered at a molecular level, leading to permanent failure.
This is because water acts as a crucial coolant for the heating element. Without it, the intense heat generated by the element has nowhere to dissipate, leading to extreme temperatures that far exceed its operational limits. The material of the heating element, typically a metal alloy, will become excessively hot and possibly warp or even melt, depending on the duration of the dry operation and the wattage of the heater.
Regularly check your water heater’s water level, especially if you notice any unusual sounds or smells. A malfunctioning pressure relief valve could lead to a significant drop in water level. Before restarting after a power outage, always verify the water level to avoid repeating this costly mistake.
Replacing a damaged heating element can be a significant expense. It’s far cheaper and easier to prevent the problem in the first place by simply ensuring there’s always enough water in the tank.
