Increase Water Pressure and Flow Rates!
Unvented cylinders are cylinders that store hot water at high pressures to give you the hot water performance you require.
They can be used in all properties small and large, electrical and gas.
Most new homes built are now fitted with unvented cylinders as standard due to the high performance.
The fact is you can use multiple taps or showers with at the same time with little or no drop in pressure or flow makes this type of cylinder very popular.
- High flow rates.
- High pressure.
- Brilliant solution for small and large properties.
- Efficient and cheap to run.
- Delivers high presuure and flow to multiple bathrooms.
- Immersion back up if gas boiler breaks down.
- Stored hot water.
- No tank required in the loft.
- No need for gas supply (direct version only)
Unvented cylinders are commonly known as Megaflo’s. This is a brand name, most boiler manufacturers have their own variant of unvented cylinder.
Megaflo has been a market leader for a while due to their lifetime guarantee on the integrity of the cylinder and the fact there is no need for an external expansion vessel as it is internal to the cylinder.
Indirect Unvented Cylinders
Indirect unvented cylinders are most commonly found in larger homes and used in conjunction with a gas central heating boiler.
The water in the cylinder is heated indirectly through water from the boiler passing through a coil in cylinder.
Direct Unvented Cylinders
Direct unvented cylinders use electrical heating elements called immersion heaters. They heat the water in much the same way as a kettle.
This type of unvented cylinder is most commonly found in smaller properties with no gas supply.
It can also be found in many larger domestic and commercial buildings where no gas heating is available.
Large homes with multiple bathrooms have always posed a problem with it being difficult to get water all round the house at a high pressure. With the old solution being installing pumps all over the place.
But now with the introduction on unvented cylinders that is a problem of the past. Used in conjunction with a system boiler, a unvented cylinder can provide high pressures and flow all over a large property.
Simply; the bigger the location and the more bathrooms the bigger the cylinder, and as unvented cylinders operate with a cold water main going directly into them there’s no need for a tank in the loft, thus proving a popular solution for people looking to convert.
If you live in a flat or apartment with no gas supply a direct unvented cylinder could be for you.
It will supply you with high pressure and flow all over and there’s no need for a gas boiler, which could save you £££’s. It is a very economical way of heating water, saving money on electricity bills.
Popular with flats with storage heaters as central heating.
There are different size cylinders available.
