Vokèra Launches Visionary New Boiler

Boiler manufacturer Vokèra has launched the Vision range of combi and system boilers. Designed to be installer-friendly and feature-rich, benefits include a rear flue option, a five-year warranty*, a built-in seven-day digital clock**, low NOx emissions and a light 26kg lift weight.

Suitable for a range of applications, the combi Vision includes 25C and 30C options and the system version is available in 20S and 25S options. Weighing just 25kg and 26kg respectively, the Vision system and combi boilers are easy for installers to lift and fit into small spaces, such as a kitchen cupboard. Further to this, the rear flue option adds to the ease of installation and gives multiple siting possibilities.

The added bonus of a built-in seven-day digital clock allows homeowners to programme bespoke heating functions per day, offering maximum flexibility. In addition, homeowners can expect a flow rate of 12 l/pm***. With the Vision’s NOx emissions being as low as 21mg/kWh, it is an ideal choice for social housing applications and can contribute towards achieving level 4 of the Code for Sustainable Homes.

Steve Cipriano, managing director of Vokèra, comments: “Our goal with the new Vision boiler was to create an installer-friendly, feature-rich product that would surpass other domestic boilers in technology, design, ease of installation and reliability.

“We seek to further enhance our already impressive range of products and continue to listen to the needs of our customers. In light of this, and to celebrate the launch, we are offering installers a five-year warranty on the Vision, if purchased before December 31 2012.”

To coincide with the launch, Vokèra is giving away a variety of rewards including football shirts, stadium tours and computer games to Affinity members purchasing their first Vision combi and/or their first Vision system boiler between July 1 and October 31 2012.

Badly fitted and poorly serviced gas appliances can cause gas leaks, fires, explosions and carbon monoxide poisoning. Every year thousands of people across the UK are diagnosed with carbon monoxide poisoning. It is a highly poisonous gas. You can’t see it, taste it or smell it, but it can kill quickly with no warning.

By taking care of your gas appliances properly you are taking care of your home and your loved ones. Follow these top tips to help keep you and your family gas safe:

  • Make sure only a Gas Safe registered engineer works on your gas appliances. Illegal gas fitters can put your life at risk
  • Always check the engineer’s Gas Safe Register ID card
  • Make sure gas appliances have a regular service and a gas safety check every 12 months
  • Look out for warning signs that your gas appliances aren’t working correctly e.g. lazy yellow or orange flames instead of crisp blue ones, black marks on or around the appliance and too much condensation in the room
  • Know the signs and symptoms of carbon monoxide poisoning – headaches, dizziness, breathlessness, nausea, collapse and loss of consciousness
  • Install an audible carbon monoxide alarm
  • If you smell gas call the gas emergency number on 0800 111 999

Benefits of high boiler modulation ratio’s explained

 

Boilers with wide modulation ratios can improve efficiencies and comfort while reducing wear and tear on components – but what does the term mean, and how can installers explain it, and its benefits, to end users?  Here Alister Maclachlan, product director at Vokèra, provides some advice following the launch of Vokèra’s Linea One boiler that boasts a modulation ratio of 10 : 1. 

In recent years some boiler manufactures have started to talk about modulation ratios – but what does the term mean and, more importantly, how does the end user benefit?

In simple terms, the modulation ratio is a boiler’s ability to reduce its maximum output to its minimum output.  A narrow modulation range gives a poor ratio whereas a wide range provides a good ratio.  For example, if a boiler has a maximum output of 30kW and a minimum output of 7.7kW its modulation ratio is less than 4:1.  Meanwhile, a boiler with a maximum output of 30kW and a minimum output of 3kW has a wider (hence better) modulation ratio of 10:1.  As a general rule, for a boiler to be classed as having a ‘good’ modulation ratio its minimum output should be one fifth or one sixth of its maximum output.

There are two important reasons why a good boiler modulation ratio is preferable – and understanding these reasons can help installers explain the benefits to end users.

Firstly, a good boiler modulation ratio reduces constant on/off cycling, improving efficiency and boiler longevity.  For example, if a boiler has a high maximum output – let’s say 40kW – yet only has a modulation ratio of 4:1 it will only be able to modulate down to 10kW.  However, when most rooms have reached the required temperature and radiator TRVs have closed, the demand on the boiler will be considerably less than 10kW.  This means that the minimum output of the boiler will be higher than it needs to be, so the boiler will constantly switch on and off – leading to fuel inefficiency and unnecessary wear and tear on its components and parts. 

A boiler with a high maximum output and a good modulation ratio, however, will be able to modulate down to an extremely low output, reducing wear and tear on primary components (fewer on/off cycles increase component longevity) and optimising fuel efficiency.

The second reason is uniquely associated with combi boilers, as it concerns the stability of domestic hot water (DHW).  A boiler with a poor modulation ratio won’t be able to maintain a stable DHW flow temperature at a low flow rate, and might even cause the burner to switch off during operation.  This can be a significant issue for end users who prefer showers over baths or for those who require a constant DHW outlet temperature – for example where there are young children or elderly people in a household, who are at a higher risk of scalding. 

So when selecting a combi boiler it’s crucial to consider modulation ratios – and to remember that performance isn’t just about kW output.  Nowadays 40kW combis are commonplace, having been introduced to improve hot water flow rates; in the 1980s a typical combi boiler had an output of 24kW (80,000BTUs) and a DHW flow rate of around 9.5l/pm at a 35oC differential, leading to end user gripes about hot water performance.  However, installing a combi boiler with a high maximum output and a poor modulation ratio in a typical UK property is unlikely to deliver optimal efficiency, or comfort. 

Let’s take a three-bedroom semi-detached house, built in the 1960s, as an example.  This type of dwelling will probably only need a maximum of 15kW for space heating, and significantly less when it has reached temperature, especially if the property is insulated and has heating controls fitted.  Hence a 40kW combi boiler that can only modulate down to 10kW isn’t good news for the customer either in the short or long term; as well as resulting in DHW instability and temperature fluctuations it will be unable to deliver fuel economy (the end user will of course be expecting their new boiler to deliver savings), and will probably suffer from early component failure.

Installers have a key role to play in ensuring that UK heating systems become more efficient, and end users will very often turn to them for advice.  We believe that an increasing number of astute installers are beginning to recognise that if a boiler can boast a wide modulation ratio it will deliver significant benefits.  It is however important to demonstrate this to customers, as it could help them in their decision making process.  Manufacturers should be able to assist by providing diagrams and literature, which can help to explain the concept – and benefits – in a simple, easy-to-understand way.

Vokèra has made a significant investment in the development of boilers with excellent modulation ratios.  Our Linea One 38kW combi boiler boasts a class-leading 10:1 modulation ratio, enabling it to modulate its output to 10 per cent of its maximum – 38kW down to 3.8kW. 

Good modulation ratios offer a range of benefits – including increased fuel efficiency, end user comfort and boiler longevity.

Vokera launches high power system boiler

 

Vokera Verve

Vokera Verve

Vokera launches high power system boiler

 

 

Vokèra is pleased to announce its latest product launch, a new large domestic and light commercial system boiler Verve.  The 47kW high-power boiler is designed to offer installers a solution for both large domestic and light commercial boiler applications.

 

Adding to Vokèra’s comprehensive range of boilers, the Verve offers a 90 per cent efficiency rating and can lead to reduced running costs of up to 35 per cent – making it one of the greenest high-power domestic boilers on the market.

 

Installers will find both the electronic regulation functions and heat engine design very familiar, being similar to those used on standard domestic boilers.  The unit itself is also relatively lightweight weighing in at just 39 kilograms, meaning the Verve is easy to handle and easier to fit. 

 

Alister Maclachlan, product director at Vokèra, comments: “We chose to launch the Verve as it offers installers the option to install a high power system boiler that is familiar in design to that of our domestic range, enabling them to expand their scope of work into larger domestic properties or small commercial premises.

 

The Verve boiler is supplied with an 80+80mm flue configuration enabling the flue to run up to 20m, or the flue can be re-configured with an optional flue adaptor to a 60/100mm or 80/125mm flue configuration. The Verve is supplied with isolating valves, enabling the boiler to be isolated from the system, which is extremely useful on larger systems, where to drain and refill the system could take several hours. 

 

Vokèra also offer a range of options to accompany the Verve, including the highly recommended hydraulic separator, which ensures the appliance is isolated from any changes in the hydraulic flow rate.  Also available is the three port valve which helps to speed up installation.
