Ideal Logic S18 System Gas boiler frequently asked questions

Is the Ideal Logic S18 a system, regular or combi boiler?

The Ideal Logic S18 is worthy of consideration if you're looking for a system boiler for your flat or house.

For homes that have a higher-than-average demand for hot water and heating and for larger properties, system boilers are a more suitable option than the more popular combi boilers.

Combi boilers heat water on demand but the amount of water they can actually deliver to taps is determined by the mains water pressure, flow rate and power. System boilers instead use a hot water cylinder that stores and keeps water hot throughout the day. As long as you remember to program the times you want hot water and the cylinder still has water left in it, you should have hot water whenever you need it.

And, unlike heat only boilers that also require a cold water storage tank to work (normally fitted in the loft), system boilers don't, meaning they're quicker, easier and cheaper to install.

Should I install a Ideal Logic S18 system boiler in my house or flat?

You should make sure that the boiler you choose for your property is the right "size". And size doesn't mean its physical dimensions. Size means how much power it has - the "output".

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the gas your boiler needs to work.

The Ideal Logic S18 system outputs at a maximum of 18 kW, so which types of property would this Ideal Logic S18 System boiler be appropriate for?

A Gas Safe engineer would recommend that the Ideal Logic S18 system boiler is a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.


Ideal Logic S18 dimensions

The Ideal Logic S18 measures 700 mm in height by 395 mm in width by 278 mm in depth.

Ideal Logic S18 – non-condensing or condensing?

The Ideal Logic S18 is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

Does the Ideal Logic S18 system protect the environment?

More and more homeowners are aware of the importance of how we heat our homes and its impact on climate change and other environmental issues.

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.

Do the available figures suggest that installing the Ideal Logic S18 system in your property would be an environmentally friendly choice?

All boilers manufactured and supplied in the UK must achieve an energy efficiency rating of at least 92% (an "A" SEDBUK grade). This is higher than the previous 88%, which was a legal requirement prior to April 2018.

The energy efficiency rating is used to work out how much energy a boiler both uses and wastes when it's switched on and working correctly - its standard functioning and operation.

The Ideal Logic S18 is rated as 93% energy efficient, equivalent to a "A" SEDBUK rating.

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use right through to final disposal.

The Ideal Logic S18 has a rating of "A".

What length of warranty does the Ideal Logic S18 come with?

The Ideal Logic S18 boiler offers a parts and labour warranty of 2 years.

Ideal Logic S18 System Gas boiler frequently asked questions

Is the Ideal Logic S18 a combi boiler, system boiler or regular boiler?

If you’re looking for a system boiler for your house or flat, you may wish to the consider the Ideal Logic S18.

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 the Ideal Logic S18 system boiler a suitable choice for my property?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Ideal Logic S18 system boiler is 18 kW kilowatts. Which types of property would this be appropriate for?

Most Gas Safe engineers would suggest that the most suitable type of property for installing a Ideal Logic S18 system boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.


Making space for the Ideal Logic S18

The Ideal Logic S18 measures 700 mm high and 395 mm wide by a depth of 278 mm.

Is the Ideal Logic S18 a non-condensing or condensing boiler?

The Ideal Logic S18 is a condensing gas boiler - where possible, we always recommend to clients that they choose one of the very latest condensing boilers to take advantage of this technology, which improves year after year.

Condensing boilers are more energy-efficient as they capture and recycle the heat contained in flue exhaust gases and water vapour condensation. They then use this heat to perform tasks like warming up colder water returning to the boiler from the radiators.

By choosing a condensing boiler, you'll help the environment as well as save money on your gas bills.

How does the Ideal Logic S18 system boiler rate environmentally?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Is the Ideal Logic S18 system boiler an environmentally friendly choice for your home? Here’s what the figures say.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Ideal Logic S18 was given an efficiency rating of 93% 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 S18 has an ERP rating of "A".

How long is the warranty offered by the manufacturer for the Ideal Logic S18 boiler?

A parts and labour warranty of 2 years is included when you purchase the Ideal Logic S18 boiler through PlumbProud.
