5 out of 5 stars

We upgraded to an unvented cylinder when renovating our bathroom. The difference in water pressure is amazing and we never run out of hot water now. The installation was neat and tidy, and the engineer explained how to get the best from our new system.

Hot Water Cylinder Installation FAQs

What's the difference between vented and unvented hot water cylinders?

Vented cylinders work at low pressure and require a cold water tank in the loft. Unvented cylinders connect directly to the mains water supply, operate at high pressure, and don't need a cold water tank. Unvented systems typically provide better water pressure but require additional safety devices and qualified installers.

How do I know what size hot water cylinder I need?

Cylinder sizing depends on your household size and hot water usage patterns. As a general guide, a 120-150 liter cylinder suits 1-2 people, 150-180 liters for 2-3 people, and 180-210+ liters for larger households. We'll assess your specific requirements to recommend the optimal size.

How long does a hot water cylinder installation take?

A straightforward cylinder replacement typically takes 4-6 hours. First-time installations or those requiring significant plumbing changes may take a full day. We'll provide a specific timeframe after assessing your requirements.

Which hot water cylinder brands do you recommend?

We install quality cylinders from leading manufacturers including Megaflo, Gledhill, Telford, and Santon. The best choice depends on your specific requirements, budget, and system type. We'll help you select the most suitable option for your circumstances.

How energy efficient are modern hot water cylinders?

Modern hot water cylinders are significantly more efficient than older models, with improved insulation reducing heat loss by up to 50%. This means your water stays hotter for longer with less energy input. Some cylinders are also compatible with renewable energy sources like solar thermal systems for further efficiency gains.
