Ideal Logic H15 - combi, system or regular boiler?

If you are searching for a heat only boiler for your house or flat, the Ideal Logic H15 is certainly one to consider.

Large family homes and properties with more than one bathroom benefit most from installing a heat only boiler (also referred to as a conventional boiler, a standard boiler or a regular boiler). Heat only boilers require both a cold water tank and hot water cylinder and an immersion heater. The immersion heater heats and keeps the water warm and feeds hot water to taps, radiators and other sources via the boiler.

Tell your boiler the times and days when you want hot water and central heating and it'll be there waiting for you. However, if you forget and there's no hot water left in your tank, you'll have to wait up to an hour before it's ready.

The biggest benefit of a heat only boiler is that, unlike a combi boiler, it’s possible to run two taps with hot water at the same time with no drop in pressure, volume or temperature (a known issue with combi boilers). It also means you can shower and have the dishwasher running at the same time without your water pressure being affected.

Is a Ideal Logic H15 heat only boiler suitable for my house or apartment?

Whether this Ideal Logic H15 heat only boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

The output of the Ideal Logic H15 heat only boiler is 15 kW, so which types of property would this be appropriate for?

An experienced Gas Safe engineer would be likely to recommend that this Ideal Logic H15 heat only boiler is capable of providing heating and hot water to up to 10 radiators and one bathroom and would therefore be most suitable for smaller homes and apartments.

Where will the Ideal Logic H15 fit in my house?

The Ideal Logic H15 measures 700 mm high and 395 mm wide by a depth of 278 mm.

Is the Ideal Logic H15 a condensing or non-condensing boiler?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Ideal Logic H15.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Ideal Logic H15 heat only good for the environment?

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.

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.

Would the environmental impact of installing a Ideal Logic H15 heat only in your home be positive? Let's look at the numbers.

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 H15 was given an efficiency rating of 93% and a SEDBUK grading of "A".

The Energy Related Products Directive (ERP) is European legislation that applies to all products which use or consume energy during their lifespan - this includes during the manufacturing process and when they're in use, right through to the point of final disposal.

The aim is to encourage manufacturers to create new products that are kinder to the environment and which create fewer harmful gas emissions.

The Ideal Logic H15 has an ERP Heat rating of "A".

If the Ideal Logic H15 heat only boiler breaks down, am I covered?

The Ideal Logic H15 boiler comes with a 2 year warranty for parts and labour.
