Customer reviews:

  1. Name of the customer– Jenni Morton

Rating- 5 out of 5 stars

Feedback- An excellent and courteous service from both the Customer service Dept. as well as the engineers.

Detail- On two occasions recently I have called Alpha and was delighted to learn that my boiler was still under warranty. The Customer service department was so helpful and on both occasions said that I would be contacted by an engineer. The swift and positive outcome was service at it’s very best and it will certainly encourage me to sign up for their service plan once the warranty has expired.

  1. Name of the customer- Dave Williams

Rating- 4.5 out of 5 stars

Feedback- After having many problems with my LPG boiler

Detail- After having many problems with my aging Alpha Boiler, I eventually called up Alpha. They sent out James Ross (Aberdeen). Really nice guy and very thorough. James gave me some great advice and directed me to apply for a Government Boiler Grant for a new boiler.

Great news… Grant applied for and a new Alpha Boiler on its way.

Detail- My boiler was due it’s service, coincidentally it ceased functioning the day before the engineer was due! I’d been told he’d arrive between 0830 and midday. He rang at 0945 to say he’d be half an hour, which he was, nice helpful chap who’d been here before. He sorted out the problem and serviced the boiler in 15 minutes. Superb service. My only moan is getting in a long queue on the phone to organise the service, but it’s Winter and I guess it’s unavoidable. To sum up, consistently excellent service all round. Thanks Alpha!



1)    My central heating does not work and my boiler is brand new?

When a boiler is installed on an existing central heating system, it is essential that the system be chemically flushed out to remove any build up of ‘sludge’ (generally iron oxides). The system should then be refilled and treated with a corrosion inhibitor / protector.

Failure to carry out this procedure (as specified in the Benchmark Central Heating Log Book) during installation may cause the new boiler to be contaminated by debris from the existing system. Because ‘modern’ boilers hold less water and are much smaller than their predecessors, they are more liable to be affected by debris in the system: heat exchangers, pumps or divertor valves are most at risk.

Also, the guarantee of the boiler can be deemed void if the debris from the old system damages your new boiler.

2)    What is a condensing boiler?

A condensing boiler is the most efficient boiler available. It converts more than 88% of the fuel it uses into heat, compared to 72% for conventional types.

Condensing boilers have either a larger or second heat exchanger which saves the heat which would normally escape up the Flue in normal boilers. This reduces the temperature of the Flue gases to a point where water vapour produced during combustion is ‘condensed out’. Hence the name ‘condensing boiler’.

Condensing boilers are established products and can be fitted to most new and old heating systems. They are easy to install and can be bought for oil and gas-fuelled homes, even LPG (liquefied petroleum gas). These boilers are often no larger than conventional boilers. You can buy condensing boilers as either combination boilers, which heat up hot water on demand, or conventional system boilers, where a separate hot water cylinder is required.

3)    What is a system boiler?

A system boiler is used for the central heating system; it is factory fitted with all the components needed for use with an external indirect cylinder for the production of domestic hot water.

System boilers neatly incorporate a number of components found outside of the boiler on traditional installations – the pump for example. Another is the Expansion vessel, which replaces the tank in the roof-space. So installation is easier and quicker and the risk of burst pipes in winter is eliminated.

4)     is a traditional boiler?

Traditional boilers (also known as heating only boilers) are used for the central heating system. Traditional boilers can deliver hot water to several taps simultaneously via an indirect hot water storage cylinder which is required as well as the boiler.

5)    Does the system need an auto by-pass?

Some of the boilers already incorporate a by-pass, however where all radiators are fitted with thermostatic radiator valves it is recommended an automatic system by-pass is fitted.

6)    My system comes on during the night or in cold weather when not asked for?

Check the minimum room temperature setting; this should be a low temperature setting e.g. 8° to 12°.

Real world case: by Phil Horrobin

After a few issues with my boiler over the years Alpha sent out the big guns and an engineer called James Ross from Aberdeenshire was sent to investigate my boiler fault.

James had every component at hand and fully explained the issues he came across. James took the time to explain how the components worked or should work and went above and beyond to ensure he left me with a safe and serviceable boiler… this is essential with young kids in Scotland in December! it was clear to me that James was a system expert and had the competence, experience, and motivation to represent Alpha in a professional manner… Thanks to James I’m sat writing this review in the warmth and my faith in the brand has been restored!


Winter days are the hardest to bear when we don’t have efficient systems to keep us warm. We crave comfort and warmth throughout the day. To solve all these issues there are quite a number of options available in the market. One of which is a boiler that also is highly functional and efficient. They provide a perfect central heating system for the house and also provide hot water for bathing and washing purposes.
