Powerful Hot Water. No Loft Tank.
Unvented hot water cylinders provide mains-pressure hot water to every tap and shower in your home. Unlike older vented systems, they don’t require a cold water storage tank in the loft, giving you stronger showers, better flow rates, and more flexibility with your home layout.
RJG Heating & Plumbing Ltd are specialists in unvented cylinder installation across Surrey. Our Gas Safe registered engineers design and install safe, efficient systems that meet all current building regulations. If you’re also upgrading your heating system, we can install your cylinder as part of a complete boiler installation
