Is the Ideal Logic H18 a combi boiler, system boiler or regular boiler?

The Ideal Logic H18 is a gas heat only boiler.

If your home has more than one bathroom or you have a large family that uses a lot of hot water, a heat only boiler (sometimes called a standard boiler, a regular boiler or a conventional boiler) is likely to be the best option for you. Heat only boilers require both a hot water or immersion cylinder and a cold water tank. Once the water in the cylinder is heated, you can use this hot water throughout the day and it can feed multiple taps and showers at the same time.

This is in contrast to a combi boiler which can only heat a limited amount of water at any one time. This can cause a problem if two or more taps and showers are being used simultaneously as the water temperature, pressure and volume to all points will drop.

Heat only boilers allow you to program the times that you want heat and hot water to be available. However, if you forget to do this and the immersion cylinder is empty, you may have to wait up to an hour before hot water becomes available again.

If your property already has a water tank and cylinder, it will nearly always be cheaper to replace like for like instead of replacing it with a different type of boiler. In addition to new pipework, you may need to replace older radiators that may be unable to cope with the higher water pressure delivered by other types of boiler.

Is the Ideal Logic H18 heat only boiler from the Logic range a suitable choice for 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 H18 heat only outputs at a maximum of 18 kW, so which types of property would this Ideal Logic H18 heat only boiler be appropriate for?

A Gas Safe engineer would recommend that the Ideal Logic H18 heat only boiler is a suitable choice for smaller homes and apartments with up to 10 radiators and one bathroom.

What size is a Ideal Logic H18 boiler?

Ideal’s Logic H18 is 700 mm tall, 395 mm wide, and 278 mm deep.

Is the Ideal Logic H18 condensing or non-condensing?

The Ideal Logic H18 is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

How does the Ideal Logic H18 heat only rate environmentally?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

Around 14% of the greenhouse gases produced in the UK is a result of our central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in some of our largest cities.

Would the environmental impact of installing a Ideal Logic H18 heat only in your home be positive? Let's look at the numbers.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Ideal Logic H18 was awarded an efficiency rating of "94%", equivalent to a "A" rating on the SEDBUK system.

The Energy Related Products Directive (ERP) came into force in 2015. This legislation was introduced to encourage manufacturers to create more energy-efficient products and it covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

The ERP assessors assigned a rating of "A" when testing the Ideal Logic H18.

Am I covered if the Ideal Logic H18 heat only boiler breaks down?

The Ideal Logic H18 boiler is covered by a parts and labour warranty of 2 years.
