A reliable hot water system is essential for everyday comfort, and Chris and the team are experts in the installation, maintenance, and repair of both open-vented and unvented hot water cylinders. We work with homeowners, landlords, and property managers across Cornwall to make sure every property has a safe, efficient, and dependable hot water supply that meets modern living standards.

Choosing the right cylinder for your home depends on your water pressure, household size, and usage. That’s why we take the time to assess your system, explain your options clearly, and recommend the most suitable solution. Whether you’re replacing an ageing cylinder, upgrading your entire heating setup, or planning a new build or extension, we’ll handle everything from start to finish—ensuring a smooth, professional installation and lasting performance.

An open-vented cylinder is a tried-and-tested system that uses a cold-water storage tank (usually located in the loft) to feed the hot water cylinder by gravity. It’s a reliable and cost-effective choice, particularly for properties with older plumbing systems or lower mains pressure. We ensure every open-vented system we install is correctly balanced, well-insulated, and designed to deliver steady, efficient hot water while keeping energy use low.

An unvented cylinder, by contrast, connects directly to your mains water supply—providing stronger pressure, faster flow rates, and the convenience of consistent hot water across multiple outlets. It’s ideal for modern homes, families, or properties with several bathrooms in use at once. Because unvented systems operate under pressure, they must be installed and maintained by qualified engineers. Chris and the team are fully certified to carry out these installations safely, in full compliance with current building and safety regulations.

Beyond installation, we also offer full servicing and maintenance for both open-vented and unvented systems. Regular checks help prevent issues such as poor performance, leaks, or pressure loss, keeping your system running efficiently year after year. If a problem does arise, we’ll diagnose it quickly and carry out any necessary repairs with minimal disruption.

With over 25 years of hands-on experience, our reputation is built on trust, reliability, and quality workmanship. We pride ourselves on our tidy approach, clear communication, and commitment to doing things properly. Whether you’re looking for a simple replacement or a complete system upgrade, you can count on Chris and the team to deliver a hot water solution that’s safe, efficient, and built to last.
