Unvented hot water cylinders

Higher performance hot water supply with a mains pressure hot water system.

Gone are the days of poor domestic hot water pressure so typical of household gravity hot water systems. Provided your incoming mains cold water is supplied at an adequate pressure you can now obtain the same performance from your hot water that you previously only enjoyed from the cold tap.

Mains pressure hot water can be achieved by utilising either an unvented cylinder or a thermal store. This section focuses on unvented cylinders. For more information on the function of a thermal store please click here.

Before you consider any mains pressure system you should familiarise yourself with how they work. You should also realise that they are only as good as the incoming mains pressure. If yours is poor or of a variable nature this may not be the way to go. Mains pressure systems may not have pumps added to them to improve performance. Indeed, if you have pumps attached to your present gravity system you will need to remove them upon conversion. Having said that, if your mains pressure is good it will outperform many booster pumps so you will gain performance without the need for a noisy pump that will inevitably break down at some point.

There are considerations to factor into your choice of system. Unvented cylinders must be installed correctly and will require periodic service checks to insure that pressure relief equipment is working safely. They will however change your perception of the dreary old hot water cylinder. Please don't hesitate to call for advice.

Unvented hot water cylinders

It is common to find unvented cylinders made from stainless steel. There is a single basic reason for this - cost! Stainless steel is cheaper than copper and by capitalising on it's higher tensile strength a thinner sheet of stainless steel can be used than if the cylinder were to be made from copper. Unvented cylinders can however be made from copper (a preferred material for water storage) they just cost more.

Unvented solar cylinders

Unvented hot water cylinders are also available with a solar coil to enable a wet solar system to contribute energy to heating hot water. Unvented solar cylinders can be Direct or Indirect.
