Baxi Megaflo 18 System Gas boiler frequently asked questions

Baxi Megaflo 18 - a system boiler, regular boiler or combi boiler?

The Baxi Megaflo 18 is a system boiler you may wish to consider if you want this type of boiler for your house or flat.

System boilers work similarly to heat only boilers in that they need a hot water cylinder (usually installed in the home’s airing or landing cupboard) to operate. Unlike heat only boilers though, system boilers don’t require a separate cold-water tank, making them a more suitable choice in homes with little or no attic space or where homeowners are planning a loft conversion in the future.

Instead of large cold-water tanks, system boilers use built-in circulating pumps to provide hot water to your taps and radiators. This makes them easier to install from scratch as they have one less component to find room for and fit.

System boilers need to be programmed with the time you want heat and hot water - they don't offer hot water on demand like combi boilers.

Should I choose a Baxi Megaflo 18 system boiler for my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Baxi Megaflo 18 system's output at 18 kW, which types of property would this Baxi Megaflo 18 System boiler be most appropriate for?

A PlumbProud heating engineer would recommend that this Baxi Megaflo 18 System boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


What are the dimensions of the Baxi Megaflo 18 boiler?

The Baxi Megaflo 18 measures 780 mm tall, 450 mm wide, and 345 mm deep.

Is the Baxi Megaflo 18 condensing or non-condensing?

Condensing gas boilers like the Baxi Megaflo 18 are more energy-efficient and choosing one for your home will cut the amount you pay every year for your gas.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

Is the Baxi Megaflo 18 system good for the environment?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Would choosing the Baxi Megaflo 18 system boiler be an environmentally friendly decision? Here's what the figures say.

Boilers manufactured in the UK must be tested and, by law, achieve an energy efficiency rating of 92% or above, equivalent to a SEDBUK "A" grade. Most boilers achieve an "A" rating meaning they are at least 88% efficient.

The energy efficiency of a boiler indicates the amount of energy it uses (and wastes) during operation.

The Baxi Megaflo 18 has been assigned an efficiency rating of 91% with a SEDBUK rating of "A".

The Energy Related Products (ERP) Directive's aim is to reduce the harmful gas emissions created during a product’s manufacture and active end use right through to its disposal.

The ERP rating for the Baxi Megaflo 18 is "TBC".

Is there a warranty on the Baxi Megaflo 18 system boiler if it breaks down?

The Baxi Megaflo 18 boiler has a warranty covering parts and labour costs for up to 7 years after installation.

Baxi Megaflo 18 System Gas boiler frequently asked questions

Baxi Megaflo 18 - a regular, combi or system boiler?

When looking for a system boiler for your house or flat, the Baxi Megaflo 18 might be a suitable option for you.

Like regular boilers, system boilers have a control panel that you use to program the times of the day when you want hot water to be available or the central heating to come on, such as in the morning when several people will be having showers or baths.

Once the water is heated, it is stored and kept warm in a hot water cylinder during the hours you've programmed. Hot water cylinders are often installed in an airing or landing cupboard and they contain built-in circulating pumps whose job is to heat water drawn from the mains.

System boilers do not need a cold-water tank like heat only boilers, making them a popular choice for homeowners who want to save space and those who are considering a loft conversion in the future. They're also easier for heating engineers to install, as they require one less large part. Instead, they use built-in circulating pumps.

Is the Baxi Megaflo 18 system boiler suitable for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your gas bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

The output of the Baxi Megaflo 18 system is 18 kW kilowatts, so which types of property would this be most suitable for?

Most heating engineers would suggest that the Baxi Megaflo 18 system boiler would be a suitable choice for installation in smaller homes and apartments with up to 10 radiators and one bathroom.


How large is a Baxi Megaflo 18 boiler?

The Baxi Megaflo 18 boiler is 780 mm high, 450 mm wide, and 345 mm deep.

Megaflo 18 – non-condensing or condensing?

The Baxi Megaflo 18 is a condensing boiler – we recommend to all clients that they choose the very latest condensing boilers because their efficiency continues to improve year after year.

Condensing boilers recycle heat from both water vapour condensation and flue exhaust gases via a secondary heat exchanger. With this heat, it performs other tasks like warming up colder water returning from your radiator without having to use more gas.

You will save money on your gas bills every year by choosing a condensing boiler as well as benefitting the environment.

Is the system Baxi Megaflo 18 boiler energy efficient?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

In the largest cities of Britain, gas boilers are responsible for dangerous levels of atmospheric nitrogen dioxide emissions. In total, 14% of the UK’s greenhouse gases are produced by central heating systems.

Do the available figures suggest that installing the Baxi Megaflo 18 system in your property would be an environmentally friendly choice?

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Baxi Megaflo 18 has an efficiency rating of 91% with a SEDBUK grade of "A".

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from their initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Baxi Megaflo 18 has a rating of "A".

What warranty does the Baxi Megaflo 18 system boiler come with?

The parts and labour warranty offered with this Baxi Megaflo 18 System boiler covers you for 7 years.
