Unvented Hot Water Cylinder Installation
An unvented cylinder delivers hot water at mains pressure to every outlet in the house at the same time. No loft tank, no weak shower on the first floor, no waiting for the flow to recover. Every installation we carry out is designed around your incoming main, the number of bathrooms and the appliances you use, then commissioned and certified under G3.
Typical unvented installs we deliver:
- New unvented cylinder replacing a vented tank and loft cistern
- Direct electric unvented cylinders where there is no gas
- Indirect cylinders fed by a boiler or heat pump
- Twin-coil cylinders combining a heat pump or solar thermal with a backup heat source
- Cylinder like-for-like swaps with expansion vessel, PRV and tundish upgrade
Vented Hot Water Systems
Vented systems still make sense in some properties, particularly where the incoming main will not support unvented flow or where the existing pipework is compatible and sound. We install, service and repair vented cylinders and can advise honestly whether an upgrade to unvented is worth doing on your property.
Annual G3 Servicing and Repairs
An unvented cylinder is a pressurised vessel and needs an annual G3 service to keep the warranty valid. Ronax Solutions services and repairs all major brands and holds parts for the systems we install. If you have lost hot water or seen the tundish discharging, book a call-out and one of our engineers will attend.
Paired with Heating and Renewables
Most cylinder jobs sit alongside other work we do in-house, so nothing gets handed off. Common combinations:
- Air source heat pump with a twin-coil cylinder
- Boiler replacement with a new indirect unvented cylinder
- Solar PV and battery with an eddi or immersion diverter

FAQs
What size unvented cylinder do I need?
As a working guide, allow around 45 litres per person for a household using mains-pressure showers, and add capacity for baths and multiple simultaneous outlets. We size against real usage on survey rather than a rule of thumb.
Can I run an unvented cylinder from a heat pump?
Yes, with a properly sized cylinder and coil surface area for low-temperature heat. We routinely pair aroTHERM plus and similar heat pumps with heat-pump-ready cylinders.
Do I need G3 certification?
Yes. Unvented cylinders must be installed and serviced by a G3-registered engineer. Ronax Solutions issues G3 certification at handover and registers the manufacturer warranty for you.
Can hot water and EV charging run off the same solar and battery system?
Yes, with the right controls. A properly configured system will prioritise household load, hot water diversion and EV charging in the order that suits you. We design this as one system rather than three separate installs.
