If you’re thinking of installing an unvented boiler system, check out our independent Megaflo review to get the facts and the pros and cons of this popular system, before you start talking to installers. 

What is an Unvented Central Heating System?

In a standard vented central heating system, cold water is supplied to the cylinder via a cold-water storage tank, usually situated in the loft. An unvented central heating system pulls cold water directly from the mains water supply bypassing the need for a cold-water storage tank. 

Why Install an Unvented Central Heating System? 

There are lots of benefits to installing an unvented system, the primary one being the reduction in space required. If a loft conversion is on your home improvement horizon, getting rid of the cold water storage tank in your attic now, might be the perfect way to go. 

This type of system also offers improved water pressure as hot water is delivered at mains pressure and doesn’t have an expansion tank or vent to deal with water expansion as it heats up and cools down. 

A modern unvented system is stacked with safety and efficiency features, like built in expansion units, relief valves, and twin thermostats, making it a very attractive option. Lack of a tank takes an extra step out of the process, corrects the working of your mains powered shower, and means that tanks aren’t affected by freezing temperatures or pollution build up in the water. 

The Megaflo Review

Now that you know all about unvented central heating systems, let’s get to the Megaflo Review – what it does, what makes it different, and the pros and cons of installing one in your home. 

What Does the Megaflo Do?

The Megaflo, a popular and award-winning product in the Heatrae Sadia’s range of heating products, although it can be used as a generic term to cover all unvented hot water storage cylinders, and combines great performance with enhanced efficiency. Perfect for our modern day demands for high pressure, hot water on demand, through several outlets at the same time. 

It is basically an unvented hot water storage cylinder which forms part of the central heating system. It heats the mains supplied cold water directly via an in-built element in the cylinder, or indirectly through your regular or system boiler. 

There is the added bonus of an immersion switch with this kind of cylinder, so should your boiler fail for whatever reason, you can activate the immersion to continue your uninterrupted supply of hot water.  

Megaflo Review – Pros and Cons

So, now you understand a bit more about the Megaflo Cylinder and what it does, let’s get into the details of the Megaflo Review – the pros and cons. 

The Pros

  • Less pipework, less building mess (and stress!) when installing. 
  • No cold-water tank – saving space and this means there is no overflow to worry about.
  • No cold-water tank means fewer opportunities for old water to become contaminated. 
  • Easy to install and maintain. 
  • Every member of your household can use hot water at the same time without affecting flow or pressure.
  • It’s easy to find replacement parts for any future repairs.
  • Works seamlessly with solar power – providing greener power options for the future or as a back-up energy source.
  • Thick 60mm of insulation. 
  • Automatic heat shut down – you don’t need to lift a finger.
  • Built-in safety features include temperature relief valve and overheating prevention
  • You can place the boiler wherever you like. 

The Cons

  • There’s no cold-water storage backup as there is no tank.
  • If you live in a low water pressure area, you will see that reflected in your hot water pressure as the supply is taken directly from the mains. Make sure your installer checks this before you install a MegaFlo.
  • Not all radiators and pipework – especially old ones – can handle the increased water pressure flowing through them. New radiators and pipework could get expensive. 
  • Water travelling through the system at such high speed can be noisy when they’re in full flow!
