Top questions London residents ask us when it comes to installing a Megaflo cylinder?

How much does it cost to install a Megaflo?

Each Megaflo installation depends on the existing water pipework and system setup, so it is difficult to provide an exact price without inspecting the current installation. We recommend sending us a picture of your existing hot water cylinder or pipework so we can provide an accurate quotation.

Do you offer recycling of old cylinder?

Yes, our installation service includes removal of the previous vented storage cylinder or any other type of cylinder.

Why is Megaflo more popular than other brands?

Megaflo has been a pioneer in unvented storage cylinders. Their unique storage cylinders are also available in slimline models with built-in expansion vessels. The built-in expansion vessels is a smart design feature, saving space.

What is the default temperature of the thermostat?

The recommended temperature is generally around 60°C. Note: This can vary depending on the model. The maximum temperature may be up to 70°C.

Do I need a shower pump with my Megaflo?

No, unvented storage cylinders use the incoming cold water mains pressure, so they do not normally require a shower pump like vented storage cylinders. This makes them a more reliable and cost-efficient system.

Can you provide a quote for Megaflo installation in London, including parking?

We do not charge parking fees for Kensington residents. We can email you a quotation with detailed pricing for the installation work we will carry out.

How long does a Megaflo installation take?

At-least around 4 hours of work is required to complete the installation but this can sometimes take a day to complete the job. One of the key time consuming task is draining the existing hot water cylinder if one exists.

Can Megaflo cylinders handle high mains water pressure?

Megaflo cylinders come with a pressure reducing valve (PRV), which ensures the water pressure is around 3 bar. So, you do not need to worry about sudden increases in mains supply pressure, which usually happen at night when water consumption is low.

Megaflo Eco vs Megaflo Slimline

Megaflo Slimline are suited for smaller tight spaces. They are great when space is limited. In terms of performance both Eco and Slimline offer the same performance. Slimline models are generally more expensive due to their compact design and space-saving benefits.

What Size Megaflo Do I Need?

The right Megaflo cylinder size depends on the size of your property, the number of bathrooms,
and how much hot water your household uses. The table below provides a general guide.

Property Typical Cylinder Size
1-bedroom flat 90–125L
2-bedroom property 125–170L
3-bedroom property 170–210L
Larger family home 210–300L

These sizes are only a general guide. The number of showers, baths, occupants and your incoming
mains water flow rate should also be considered before choosing a Megaflo cylinder.
