Why Choose an Unvented Hot Water System?
If you have a large home in Hull or East Yorkshire with multiple bathrooms, a standard combi boiler might struggle to provide enough hot water to two showers at the same time. An unvented hot water cylinder stores water directly from the mains supply, delivering powerful, high-pressure hot water to all your taps and showers simultaneously.
- Mains pressure hot water at all outlets, simultaneously
- No need for a cold water storage tank in the loft (frees up space)
- Perfect for larger homes with multiple bathrooms and en-suites
- Faster filling baths and powerful, invigorating showers
- Highly insulated cylinders for excellent energy efficiency and heat retention
- Requires a G3 qualified engineer to install and service safely
