Ideal Logic S15 System Gas boiler frequently asked questions

Is the Ideal Logic S15 a system, regular or combi boiler?

If you’re looking for a system boiler for your house or flat, you may wish to the consider the Ideal Logic S15.

System boilers need a hot water cylinder to work, with the most popular installation location for cylinders being in an airing or landing cupboard. Unlike heat only boilers though, they don't require a separate cold water tank to go in the attic, making them suitable if roof space is at a premium or if you're planning a loft conversion in the future.

System boilers use (often built-in) circulating pumps to distribute hot water to your taps and radiators. Fitting is cheaper and quicker too because you don't need to find room for a water tank. Unlike with a combi boiler, which heats water it draws from the mains instantly, you have to program a system boiler with the times you want hot water and heating.

Is a Ideal Logic S15 system boiler suitable for my apartment or house?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Ideal Logic S15 system's output is 15 kW, so which types of property would this Ideal Logic S15 System boiler be appropriate for?

To most experienced Gas Safe engineers, the Ideal Logic S15 system Logic would be most suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


What are the dimensions of the Ideal Logic S15 boiler?

The Ideal Logic S15 measures 700 mm in height by 395 mm in width by 278 mm in depth.

Ideal Logic S15 – condensing or non-condensing?

We recommend the Ideal Logic S15 as it is a modern condensing gas boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more gas.

Condensing boilers significantly reduce your quarterly gas costs and they're better for the environment.

How does the Ideal Logic S15 system rate environmentally?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Will choosing to install a Ideal Logic S15 system in your home help the environment? Let's review the figures.

By law, the minimum level of energy efficiency for boilers manufactured in the UK is 92%, equivalent to a good SEDBUK “A” rating. Prior to April 2018, the minimum was 88% - boilers whose energy efficiency levels were 88% or 89% were given a "B" rating on the SEDBUK scale and those at 90% or higher were given an "A".

The energy efficiency rating awarded to each boiler indicates the amount of energy that is wasted when in operation.

Following testing, the Ideal Logic S15 was given a 93% energy efficiency rating and a SEDBUK grading of "A".

The Energy Related Products Directive intends to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Ideal Logic S15 has an ERP rating of "A".

What is the warranty period for the Ideal Logic S15?

The parts and labour warranty on the Ideal Logic S15 covers all repair-related costs for 2 years while the heat exchange warranty covers you for [Heat Exchange Warranty] years.

Ideal Logic S15 System Gas boiler frequently asked questions

What type of boiler is Ideal’s Logic S15 - system, regular or combi?

If you are considering installing a system boiler in your house or flat, then the Ideal Logic S15 boiler is certainly worth investigating.

System boilers are very popular for properties with limited or no loft space or when homeowners want to keep the space for a loft conversion. This is because, unlike heat only boilers, they don’t require a cold-water tank - however, system boilers do need a hot water cylinder (often installed in an airing or landing cupboard).

Instead of the traditional cold-water tanks, system boilers use their built-in circulating pumps to heat the water needed for your taps and radiators. This also makes them an easier choice for engineers to install as there is one less large component to find space for and fit.

Like a regular boiler, you need to use a control panel to control a system boiler. Set the times when you want central heating and hot water to be available, such as in the morning when there might be greater demand for showers, and it will be there. Although hot water is not available on-demand like with a combi boiler, once the water has been heated it will stay in the hot water cylinder until it’s used up.

Is a Ideal Logic S15 system the right boiler for my house or flat?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher gas bills.

Which types of property would this Ideal Logic S15 System boiler be appropriate for given its output of 15 kW?

An experienced PlumbProud boiler engineer would likely recommend this Ideal Logic S15 System boiler as suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


Making space for the Ideal Logic S15

The size of the Ideal Logic S15 boiler is 700 mm tall, 395 mm wide, and 278 mm deep.

Is the Ideal Logic S15 non-condensing or condensing?

We strongly recommend that you choose a condensing boiler like the Ideal Logic S15 - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

What energy efficiency ratings have been awarded to the Ideal Logic S15 system?

How we heat our homes and the damage this does to the environment has become a pressing concern for many homeowners worried about the effects and impact of climate change.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Will installing a Ideal Logic S15 system in your home be a positive contribution to the environment? The figures below will tell you more.

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Ideal Logic S15 was given an efficiency rating of 93% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

The ERP (or Energy Related Products Directive) is European legislation affecting products that consume energy throughout their lifetime.

The aim is to encourage companies to create environmentally friendlier products that reduce harmful gas emissions during manufacturing and when in use by the end client, right through to their eventual disposal.

In the case of the Ideal Logic S15, the ERP rating is "A".

Is this Ideal Logic S15 system covered by a warranty?

The manufacturer offers a parts and labour warranty of 2 years on the Ideal Logic S15 boiler to new customers.
