What is an Unvented Hot Water Cylinder?

An unvented hot water cylinder simplifies the heating system within your home by removing the need for a cold water storage tank in the loft. By removing this you not only save space but you should also have higher pressure from your water system.

There are no vents to cope with excess heated water but in-built safety features like an expansion unit or an air bubble within the tank are used to remedy this.

What Is An Indirect Hot Water Cylinder?

An indirect hot water cylinder relies on an external source to heat up the water, like a boiler or something similar. This feeds the hot water into the cylinder with an internal coil that helps keep the water hot whilst it passes through.

Internal Expansion System

The great thing about the internal expansion system is that it does not require you to have a separate expansion vessel, as it keeps external pipework to a minimum. Any expansion within the Megaflo Eco can be accommodated, meaning no unsightly expansion vessels are on show, therefore giving you a neat, compact and tidy installation.

Coil-in-Coil Heat Exchanger

Featuring in indirect models, a high performance ‘coil-in-coil’ heat exchanger which delivers exceptionally fast recovery times. No more waiting around for your water to heat up, as heat exchanger coils maximise the heat transfer to ensure a quick heat-up process. This cylinder will provide water to several outlets at the same time flawlessly, so you don’t have to wait your turn. Another benefit is that inside the cylinder is a 3kW immersion heater, which allows the water to be internally heated and ready to use.
