Unvented Hot Water
& Pressure Boosting
Expert installation and servicing of unvented hot water cylinders and mains water pressure boosting systems. Enjoy powerful, consistent hot water throughout your home.
Unvented Hot Water Cylinders
Unvented hot water systems deliver mains-pressure hot water to every outlet in your home. Unlike traditional vented systems that rely on a cold water tank in the loft, unvented cylinders are fed directly from the mains supply — giving you powerful, consistent water pressure at every tap, shower, and bath. We are fully G3-qualified to install, service, and maintain unvented systems from all leading manufacturers.
Mains Pressure Hot Water
Enjoy powerful, consistent hot water pressure at every tap and shower throughout your home — no more waiting for tanks to fill.
No Cold Water Tank Required
Unvented cylinders connect directly to the mains supply, freeing up valuable loft space and eliminating the risk of frozen or contaminated tanks.
Multiple Outlets Simultaneously
Run multiple showers, baths, and taps at the same time without any drop in pressure or temperature.
Fast Recovery Times
Modern unvented cylinders reheat quickly, ensuring you always have hot water available when you need it.
Energy Efficient
High-quality insulation and direct mains connection mean less heat loss and lower energy bills compared to traditional vented systems.
Professional Installation
All our unvented installations are carried out by G3-qualified engineers, fully compliant with Building Regulations Part G3.
