How It Works

This is a system boiler and is more commonly found in older houses. System boilers store hot water, usually in the loft so that it’s readily available when needed. This is unlike a combi system that heats the water on demand. There are pros and cons to both systems. For example a combi boiler may be slightly more efficient because the stored water loses heat over time. However, the heat-on-demand method can cause a loss of pressure when more than one hot water faucet is being used at a time.

The 30CDi is Worcester’s most popular system boiler. This is a powerful model that is best suited to larger properties with larger heat loads or demanding hot water usage. There is a 5 year guarantee on the boiler itself, and a 10 year guarantee on the primary heat exchanger. At Hassle Free Boilers, we also offer a pay monthly plan where you pay nothing upfront, and all maintenance and repairs are included for a small monthly charge. Contact us today to find out more.

Remember, in the UK, a gas boiler accounts for roughly 60% of home energy usage. If the 30 CDi doesn’t quite pack the punch you’re after have a look at the 35CDi, the largest system boiler in the Worcester range.
