Alpha Combi Range

Alpha CD28X Combi Gas BoilerMost of us want to maximise our space at home, which is why so many people choose a combination or ‘combi’ boiler. Why? Because with this type of boiler, there’s no need to make room for a bulky water tank or a hot water cylinder. Plus, you have the added convenience of hot water on demand as soon as you turn on your tap without having to wait for a cylinder to reheat. And because you aren’t using energy to heat and store a whole cylinder of hot water, you could save money on heating bills too as you only heat as much water as you use.

A combi boiler provides both hot water and central heating from one compact unit which you can install in a wide range of locations in the home.

Benefits of an Alpha Combi boiler

  • Lots of brands and product ranges to choose from so you can find the right fit for your needs
  • Enjoy the benefits of hot water on demand
  • Make the most of your loft and airing cupboard space
  • No worries about wasting water or energy – you only heat what’s needed

Alpha Regular Range

Alpha CD24R Range Regular Gas BoilerIf you are looking for a modern replacement for an older heating system, the chances are you’ll need to give some consideration to a regular boiler.

Also known as a conventional or traditional heating system, this type of boiler works with a hot water cylinder (usually in an airing cupboard) plus a cold water storage tank (which is usually in the loft). While many modern homes are choosing to swap their traditional Regular boiler for a System or Combi, some householders find that it makes more sense to stick with the Regular, especially if you have a large home with a high demand for hot water or you’re not planning to change the pipework already in place.

Benefits of an Alpha Regular boiler

  • Comes in a range of sizes
  • Suitable for older properties with a traditional central heating system in place
  • Gives plenty of hot water for standard use

Alpha System Range

Alpha ProTec Plus 115 System BoilerFor homes that expect to use lots of hot water, for example those with multiple bathrooms or shower rooms, a system boiler makes sense.

The Alpha range of system boilers includes a range of outputs so you can match capacity with your expected requirements.

One of the key selling points of a system boiler is that the hot water storage cylinder is always topped up, so you can be sure of a hot shower or bath.

If others in your home want to use the bathroom after you, then the hot water that’s been used is automatically topped up. Most people position the hot water cylinder in an airing cupboard.

Benefits of an Alpha System boiler

  • Suitable for various sizes of property
  • Hot water always available as the cistern automatically replenishes
  • Alpha offer plenty of choice to suit most heating and water requirements
  • Large capacity options available in the range

Compare the Prices of Alpha System boilers

How much you spend on your boiler depends not only on the brand and product range but also on the size of the boiler, i.e. how powerful it is. The more bedrooms, bathrooms and radiators you have (and the more people in your household) the higher the output of the boiler needs to be. This is measured in kW (kilowatt) and tends to range from 24 – 42kW in domestic boilers. If you’re not sure which size you need, you can always take advice from a Gas Safe heating engineer.

You’ll also need to contact more than one engineer to get quotes for installation, so that you can be sure you’re getting the best deal from your new heating system. Get quotes for a new Alpha boiler.

Alpha Boiler Service

It’s important to keep your boiler in the best possible condition with an annual boiler service by a professional engineer. This will ensure the boiler can operate as efficiently as possible, keeping heating bills to a minimum, and that there are no potential safety issues to be concerned about. A boiler service is also a great way to catch and fix small repairs before they have the chance to worsen over time and cause an expensive breakdown. Find out what’s involved in an annual boiler service, why it’s so important, the benefits and how much they cost in Alpha Boiler Service.

Alpha Boiler Warranty

Every boiler manufacturer offers a standard warranty with their boilers which last between 1-10 years. The warranty is your insurance policy and means if a fault develops the manufacturer will resolve it within a specified time frame. Some warranties include both parts and labour while others may only cover parts. The most important thing to remember is to get your boiler serviced by a Gas Safe registered engineer every year as failing to do so is likely to invalidate your warranty. For more detail about this brand’s warranty (including the small print) take a look at Alpha Boiler Warranty.

Alpha Boiler Repair Advice

Even the highest quality boiler can develop faults and problems as they age. Some are minor issues you may be able to handle yourself but most will need a Gas Safe registered engineer to diagnose and repair the problem. To find out if there are any common problems associated with this manufacturer you can read our guide to Alpha Boiler Repairs & Common Alpha Boiler Problems.

Alpha Error Codes

Error codes may appear on your boiler’s display; it’s your boiler’s way of telling you that something is wrong. Each manufacturer uses a different coding system to help an engineer to diagnose a fault. In some cases it may be a simple issue such as low pressure which you can adjust yourself but more technical faults will certainly need a professional. We’ve put together a list of Alpha Error Codes to help you understand what’s wrong before you contact an engineer.

Alpha Renewable Heating Solutions

Alpha also offer a solar thermal system called SolarSmart. Solar collectors are fitted to your roof where they can capture the heat from the sun and use it to heat water in a cylinder. SolarSmart is designed to work alongside Alpha’s InTec combi boilers so that the boiler can act as a backup source of hot water when there is inadequate sunlight to meet demand. Solar thermal systems enabled you to buy less energy from a supplier reducing both your energy bills and CO2 emissions.

The SolarSmart 100 is the latest version of Alpha’s solar thermal system and includes the following:

  • Space saving 100 litre cylinder
  • Easy plug-in controls
  • Fully WRAS approved system
  • 10 year guarantee on collector and cylinder
  • Choice of ‘in-roof’, ‘on-roof’ and ‘flat roof’ fixing kits
  • Can be retrofitted to any Alpha high efficiency boiler with Solar Valve
  • Alpha Boiler Controls
