Vokera Compact A 25A Combi Gas boiler frequently asked questions

What kind of boiler is the Vokera Compact A 25A - standard, combi or system?

If you’re looking for a combi boiler for your house or flat, you may wish to the consider the Vokera Compact A 25A.

Combi boilers provide hot water or heating for your home on demand. You just need to turn the tap to get hot water or switch on the radiator and you’ll feel your home warm up within minutes.

In contrast, traditional boilers required either one or two large storage tanks to work - one to heat and keep water warm and the other to hold cold water for later heating. If the immersion tank was empty, it wasn’t uncommon to wait up to an hour for enough hot water to fill a bath, for example.

Combi boilers draw cold water from the mains and then heat it instantly whenever it's needed, all from one small unit.

The one disadvantage to combi boilers is that, if more than one point is in use at any one time (for example, if someone is taking a shower and another person turns on a hot water tap elsewhere in the property), water pressure, temperature and volume drop to both points.

Should I install a Vokera Compact A 25A combi boiler in my home?

Whether this Vokera Compact A 25A Combi 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.

The output level of a boiler tells you how much power it has to heat the water coming from your taps and warming up your radiators. The higher the output level, the greater the volume of water it can heat up.

If the output (measured in kilowatts) is too high, you'll pay higher gas bills and your water will be piping hot. Too low and the water coming out of your taps and being fed into your radiators will often be lukewarm.

The Vokera Compact A 25A combi outputs at a maximum of TBCkW, so which types of property would this Vokera Compact A 25A Combi boiler be appropriate for?

Most Gas Safe engineers would suggest that the most suitable type of property for installing a Vokera Compact A 25A combi boiler would be smaller homes and apartments with up to 10 radiators and one bathroom.

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 Vokera Compact A 25A Combi boiler's flow rate is TBCl/m.

As with all combi boilers, the Vokera Compact A 25A 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.


What dimensions does a Vokera Compact A 25A have?

The Vokera Compact A 25A boiler is TBC mm high, TBC mm wide, and TBC mm deep.

Vokera Compact A 25A – condensing or non-condensing?

The Vokera Compact A 25A 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.

Is the Vokera Compact A 25A combi boiler good for the environment?

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Let's take a closer look at whether installing a Vokera Compact A 25A combi would be a good choice for the environment.

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 Vokera Compact A 25A scored an efficiency rating of 93% and a SEDBUK band rating of A.

Am I covered if the Vokera Compact A 25A combi boiler breaks down?

You receive a parts and labour warranty of TBC years with the Vokera Compact A 25A boiler.

Vokera Compact A 25A Combi Gas boiler frequently asked questions

Is the Vokera Compact A 25A a combi, system or regular boiler?

Suitable for a house or a flat, the Vokera Compact A 25A combi boiler is worth considering if you want a combi boiler.

Combi boilers are excellent for providing hot water and heat for your radiators just when you need it. When you have a combi boiler installed in your home, you just turn on the tap and the hot water for your bath, shower, washing dishes and other activities is there when you need it. It also provides the heat you need to keep your radiators warm.

A combi boiler heats the cold water passing through it, which it draws from the mains. This newly heated water can then be distributed to whichever hot tap or radiator needs it.

In the past, boilers needed at least one storage tank to hold water that was either already heated or would be heated later. Sometimes, you'd have to wait for hot water because there was none left. In addition, storage tanks took up a lot of space and most UK homes are pretty small.

The main disadvantage to combi boilers is that they can only heat a certain amount of water at any one time, meaning the pressure, volume and temperature of water will decrease if more than one tap is on at the same time or if both the shower and washing machine are on together.

Should I install a Vokera Compact A 25A combi boiler in my house or apartment?

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 Vokera Compact A 25A combi outputs at a maximum of TBCkW, so which types of property would this Vokera Compact A 25A Combi boiler be appropriate for?

Most heating engineers would suggest that the Vokera Compact A 25A combi boiler would be a suitable choice for installation in smaller homes and apartments with up to 10 radiators and one bathroom.

With combi boilers like the Vokera Compact A 25A, you need to take the flow rate into account as well as the output rate.

Combi boilers draw water from the mains and then instantly heat that water and send it to wherever in your home it's needed. Flow rates, measured in litres per minute, are subject to the mains water pressure in your area. So, for example, if the local mains water pressure is 11 litres per minute and the flow rate of your boiler is 14 litres per minute, the boiler will not be able to process more than 11 litres per minute. The flow rate of this Vokera Compact A 25A Combi boiler is TBCl/m.

If you live in a home with lots of radiators or bathrooms where many people want to use hot water at the same time, a combi boiler may not be able to cope. For reference, a power shower uses about 10 litres of water per minute. If two people want showers at the same time or one person wants a shower and the other hot water from a tap in the kitchen, your boiler may not have a large enough flow rate even if the local mains water pressure is high.

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 size is the Vokera Compact A 25A boiler?

The Vokera Compact A 25A occupies a space of TBC mm high by TBC mm wide and TBC mm deep.

Is the Vokera Compact A 25A non-condensing or condensing?

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Vokera Compact A 25A are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

Is the Vokera Compact A 25A combi good for the environment?

With growing concern among the public about accelerating climate change, how we heat our homes and the impact this has on the environment has become a major topic of concern for many homeowners.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Would choosing a Vokera Compact A 25A combi help in the fight against climate change? What do the performance statistics suggest?

All boilers manufactured in the UK from April 2018 must operate at a minimum level of energy efficiency of 92% ("A" rating on the SEDBUK scale). Before that, the minimum was 88% - boilers scoring 88/89% were given a SEDBUK "B" rating and 90% or above an "A" rating.

The energy efficiency score of a boiler indicates how much energy it uses and how much goes to waste when in use.

After its assessment, the Vokera Compact A 25A was given an efficiency rating of 93% and a SEDBUK grading of "A".

What length of warranty does the Vokera Compact A 25A come with?

You receive a parts and labour warranty of TBC years with the Vokera Compact A 25A boiler.
