Is the Atag IR 15 a system, regular or combi boiler?

You may wish to consider installing the Atag IR 15 if you are looking for a heat only boiler for your house or flat.

Heat only boilers (often referred to as standard boilers, regular boilers or conventional boilers) need both a hot water cylinder and a cold water tank to work. The hot water cylinder heats and keeps warm the water you need and is normally installed in either a utility room or attic. The cold water tank holds water which it passes to the hot water cylinder depending on how you've programmed your boiler.

When you program a heat only boiler, you set the times and days when you want central heating and hot water to be available. However, if you don't remember to program your boiler and there's no water left in the hot water cylinder, you may have to wait up to an hour for hot water to come out of your taps.

Heat only boilers can cope with the demand for hot water from multiple taps and sources around your home simultaneously. That's why they're better for larger homes than combi boilers - combi boilers struggle when more than one hot tap is turned on. This is because they have a maximum capacity of water they can heat and distribute at any one time, meaning water pressure, temperature and volume to each tap drops.

Is the Atag IR 15 heat only boiler a suitable option for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Atag IR 15 heat only's output at 14 kW, which types of property would this Atag iR 15 heat only boiler be most appropriate for?

A Gas Safe boiler installer would recommend that this Atag iR 15 heat only boiler would provide adequate heating and hot water for smaller homes and apartments with up to up to 10 radiators and one bathroom.

What size is a Atag IR 15 boiler?

The Atag IR 15 boiler is TBC mm high, TBC mm wide, and TBC mm deep.

IR 15 – non-condensing or condensing?

The Atag IR 15 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.

Is the Atag IR 15 heat only boiler an environmentally friendly choice?

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

14% of the UK’s greenhouse gas production comes from central heating. In the bigger cities, gas boilers in particular are responsible for dangerous levels of nitrogen dioxide emissions.

Would installing the Atag IR 15 heat only in your home be an environmentally friendly decision? Let's look closely at the figures.

All boilers manufactured and installed in the UK are required by law to have an energy efficiency rating of at least 92%, equivalent to a good “A” rating on the SEDBUK scale. Before this, the minimum was 88% (ratings of 88% and 89% are equivalent to a high “B” SEDBUK rating and anything 90% or higher is an "A" rating).

A boiler's energy efficiency rating is designed to let you know how much energy is used and wasted during normal functioning.

The Atag IR 15 was given an efficiency rating of 94% and a band rating of "A".

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 Atag IR 15 has a rating of "A".

If the Atag IR 15 heat only boiler breaks down, am I covered?

The Atag IR 15 boiler is provided with a parts and labour warranty lasting 14 years.
