Daikin D2CND 28 Combi Gas boiler frequently asked questions

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

You might want to consider the Daikin D2CND 28 for your house or flat if you are looking for a combi boiler.

Traditional boilers require at least one large cylindrical tank to work, normally housed in a large landing cupboard, utility room or the attic. As the UK has some of the world's smallest residential properties, manufacturers introduced the combi boiler in the 1970s to address the issue of space while meeting homeowners' need for central heating and hot water at the same time.

Combi boilers don't need external storage tanks. Instead, they draw water directly from the mains, heat it and then distribute it on demand to the areas where it is needed.

The most important disadvantage of combi boilers is that they have a maximum capacity for the amount of water they can heat up. This means that, if one person in your household is having a shower and another person turns on a hot water tap elsewhere, then the volume, pressure and temperature of the water to both points decreases.

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

To determine that, we need to consider the size of the boiler. However, size doesn't refer to how big a boiler is - it means the size of its "output".

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Daikin D2CND 28 combi is 28 kW, so which types of property would this Daikin D2CND 28 Combi boiler be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Daikin D2CND 28 Combi boiler is appropriate for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

If you are thinking about installing a combi boiler like the Daikin D2CND 28 in your home, you should consider flow rates as well as output rates. This Daikin D2CND 28 Combi boiler's flow rate is 14 L/m.

The flow rate indicates the maximum volume of water (measured in litres per minute) that your boiler can heat up and send to your radiators, taps and showers at any one time. The more taps and showers that could be in use simultaneously or the greater the number of radiators you have, the higher the flow rate you need.

However, you should establish what the mains pressure is at your property as a combi boiler can only heat the water that comes into your home.

For example, if your mains pressure is 12 litres per minute, your boiler can only heat and distribute hot water at a rate of 12 litres per minute even if it has a higher flow rate capacity. Typically, a power shower will require 10 litres of water per minute.

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.


Where will the Daikin D2CND 28 fit in my house?

The Daikin D2CND 28 is TBC mm [H] by TBC mm [W] by TBC mm [D] in size.

Daikin D2CND 28 – condensing or non-condensing?

The Daikin D2CND 28 is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

How environmentally friendly is the Daikin D2CND 28 combi?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

Central heating systems are responsible for 14% of greenhouse gas emissions in the UK. You may also be aware that the gas boilers we use emit dangerous nitrogen dioxide in large volumes in the bigger British cities.

Is the Daikin D2CND 28 combi an environmentally friendly choice for your home? Let’s have a look at the figures.

Boilers manufactured or supplied to UK domestic properties must achieve a legal minimum energy efficiency rating of 92% (equivalent to a good "A" grade using the SEDBUK scale). Prior to this, the minimum was 88% (88% and 89% are a "B" SEDBUK grade and anything 90% or above is an "A" grade).

The energy efficiency rating of a boiler refers to the amount of energy it uses to perform its everyday functions as well as the amount of energy it wastes.

The Daikin D2CND 28 has been given a rating of 93.1% for energy efficiency, equivalent to a SEDBUK "A" rating.

What warranty does the Daikin D2CND 28 combi boiler come with?

The Daikin D2CND 28 boiler offers a parts and labour warranty of 2 years.

Daikin D2CND 28 Combi Gas boiler frequently asked questions

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

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

Traditional boilers often have up to two tanks that either store heated water or water to be heated later. Boiler manufacturers introduced combi boilers in the 1970s to avoid the need for those big tanks. Combi boilers allow homeowners to benefit from the reliable central heating and hot water level they want but without having to give up so much space within their properties - remember that homes in the UK are among the smallest in the developed world.

Your taps and radiators get the hot water they need with a combi boiler. Combi boilers draw cold water direct from the mains which is then heated instantly on demand and distributed to your radiators and taps.

However, combi boilers cannot heat very large volumes of water, which is their main disadvantage. So, for example, when someone wants to take a shower while another person wants to use a hot water tap to do the dishes, water pressure and quantity to both points decreases.

Would the Daikin D2CND 28 combi be a suitable choice of boiler for my house or flat?

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

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Daikin D2CND 28 combi's output at 28 kW, which types of property would this Daikin D2CND 28 Combi boiler be most appropriate for?

An experienced boiler engineer would recommend that this Daikin D2CND 28 Combi boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.

You should also consider a combi boiler's "flow rate" when making your choice.

The flow rate indicates how much water it can take from the mains supply at any one time (measured in litres per minute), which it then heats and distributes to different points in your home like your bathroom, kitchen and radiators. This Daikin D2CND 28 Combi boiler's flow rate is 14 L/m.

Combi boilers have no storage tanks like system or heat only boilers. This means that if the water pressure where you live is low, there's no benefit in spending money on a combi with a high flow rate because a high flow rate doesn't mean it can draw any more water from the mains.

In addition, there might be lots of people in your household who want to use hot water at the same time while also having the central heating on. Given that average mains pressure in the UK is between 10 and 12 litres per second and a power shower usually requires about 12 litres of water per minute, a combi boiler might not be the right choice for you and your family.

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.


The size of the Daikin D2CND 28

The Daikin D2CND 28 is TBC mm in height, TBC mm in width and TBC mm in depth.

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.

How does the Daikin D2CND 28 combi boiler rate environmentally?

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.

As much as 14% of the UK’s greenhouse gas production derives from our domestic central heating systems. Gas boilers are responsible for dangerous levels of nitrogen dioxide emissions in Britain's largest cities.

If you decide to install a Daikin D2CND 28 combi in your home, will you be helping the environment with your choice? Let’s have a look at the figures.

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.

Will I be covered if the Daikin D2CND 28 combi breaks down?

The Daikin D2CND 28 is supplied with a parts and labour warranty of 2 years.
