Daikin D2CND 28 Combi Gas boiler frequently asked questions

Is the Daikin D2CND 28 a system, regular or combi boiler?

The Daikin D2CND 28 is an option you may wish to consider if you’re looking for a combi boiler for your house or flat.

Combi boilers have much to recommend them - not least the fact that they save a lot of space. Combination (or combi) boilers were introduced by manufacturers in the 1970s to provide practical central heating and hot water distribution to smaller properties - remember that UK houses and flats tend to be among the smallest in the developed world.

Traditional boilers require one or more storage tanks to keep hot water warm and to store water for heating later. In contrast, combi boilers draw water directly from the mains supply and heat it instantly, removing the need for a storage tank. The heated water is then distributed to your taps and radiators on demand.

While combi boilers are suitable choices for many properties, especially those without a loft, there is also a disadvantage in using them. Water is heated instantly and the volume of water that can be heated at any one time is limited. This can result in less water being sent to taps and showers if more than one is being used simultaneously. In these instances, the water pressure to both points will drop.

Is a Daikin D2CND 28 combi boiler suitable for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your gas bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

The output of the Daikin D2CND 28 combi is 28 kW kilowatts, so which types of property would this be most suitable for?

An experienced PlumbProud boiler engineer would recommend that this Daikin D2CND 28 Combi boiler be installed in medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

You'll also need to be sure to choose a combi boiler with the right flow rate for your home.

The flow rate indicates the maximum volume of hot water (measured in litres per minute) that your boiler can distribute at any given time. This means that if you and your family are likely to be using several taps and showers simultaneously or you have a lot of radiators, you need a boiler with a high flow rate. This Daikin D2CND 28 Combi boiler's flow rate is 14 L/m.

As with all combi boilers, the Daikin D2CND 28 is only able to heat and distribute water at the rate at which it actually enters your property.

For this reason, you shouldn't purchase a boiler with a very high flow rate if the flow rate in your mains pipes is lower because the extra capacity doesn't mean it can draw more water from the mains pipes.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


How large is a Daikin D2CND 28 boiler?

The size of the Daikin D2CND 28 boiler is TBC mm high, TBC mm wide, and TBC mm deep.

Is the Daikin D2CND 28 non-condensing or condensing?

We recommend that you choose a condensing boiler wherever possible like the Daikin D2CND 28 - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

Does the Daikin D2CND 28 combi protect the environment?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

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

Would choosing a Daikin D2CND 28 combi help in the fight against climate change? What do the performance statistics suggest?

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Daikin D2CND 28 was given an efficiency rating of 93.1% and a SEDBUK grading of "A".

Does a Daikin D2CND 28 combi boiler come with a warranty period?

You receive a parts and labour warranty of 2 years with the Daikin D2CND 28 boiler.

Daikin D2CND 28 Combi Gas boiler frequently asked questions

Daikin D2CND 28 - a system boiler, regular boiler or combi boiler?

The Daikin D2CND 28 is worthy of consideration if you're looking for a combi boiler for your flat or house.

Traditionally, boilers needed one or more large tanks installed in your property to store their heated water or water that was to be heated later. These tanks were often too large to be practical for most homes so the combi boiler was introduced to Britain in the 1970s by manufacturers to help homeowners overcome this issue.

Instead of using tanks as storage, a combi boiler heats water on demand. It draws water from the mains and heats it instantly on demand before distributing it to wherever it is needed in a property, be it your taps or radiators.

Unfortunately, combi boilers have one main disadvantage for larger properties or larger households. Because they have a maximum volume of water that can be heated on demand at any given time, water pressure, volume and temperature will drop if, for example, someone is taking a shower and another person in your home wants to use a hot water tap at the same time.

Should I install a Daikin D2CND 28 combi boiler in my house or flat?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Daikin D2CND 28 combi's output level is 28 kW, so which types of property would this Daikin D2CND 28 Combi boiler be an appropriate choice for?

A heating engineer would recommend that this Daikin D2CND 28 Combi boiler would be a suitable installation choice for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

If you are considering installing a combi boiler in your home, you need to consider the flow rate as well as the output rate.

The flow rate is the volume of water (measured in litres per minute) that your boiler can instantly heat up and send around the home. The more demand in your home for water at the same time (for example, two people taking showers in different bathrooms), the higher the flow rate you'll need.

However, the actual flow rate your boiler can deliver is also determined by your mains water pressure. If you choose a boiler with a flow rate of 16l/m but the mains water pressure is 12l/m, your boiler will only perform to 12l/m. This Daikin D2CND 28 Combi boiler's flow rate is 14 L/m.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


What are the proportions of a Daikin D2CND 28 boiler?

The Daikin D2CND 28 is TBC mm high by TBC mm wide by TBC mm deep.

Is the Daikin D2CND 28 a condensing or non-condensing boiler?

We recommend the Daikin D2CND 28 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.

Is the Daikin D2CND 28 combi an energy-efficient boiler?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Will installing a Daikin D2CND 28 combi in your home be a positive contribution to the environment? The figures below will tell you more.

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Daikin D2CND 28 scored an efficiency rating of 93.1% and a SEDBUK band rating of A.

If the Daikin D2CND 28 combi boiler breaks down, am I covered?

Daikin’s D2CND 28 boiler includes a parts and labour warranty of 2 years.
