Alpha E-Tec Regular Boiler

The Alpha E-Tec Regular is suitable for homes that already have a traditional heating system

Boasting the same attributes as the E-Tec combi and system boilers, the Alpha E-Tec Regular is an efficient gas boiler that is designed to save you money on your energy bills. It’s a compact boiler and can be fitted almost anywhere in your home, making it a great choice if you don’t have a lot of storage space to play with. That said, the boiler requires a hot water storage cylinder and a tank in the loft, so it’s better suited to homes with an existing traditional heating and hot water system.

How Much Does this Boiler Cost?

The Alpha E-Tec Regular can be purchased with an output of 15kW, 20kW or 25kW and will set you back anything between £709 and £809, including VAT. However, you also need to pay for the installation as well, so be sure to set aside some extra cash to cover this. The 15kW unit is best for smaller homes and the 20kW and 25kW units are designed for medium to large-sized homes with higher heating and hot water demand.

How will I know if this Boiler is Suitable for My Home?

Alpha’s E-Tec Regular has to be installed with a cold water storage tank and a feed and expansion tank, usually found in a loft. But that’s not all. This boiler needs to be fitted alongside a hot water storage cylinder to be capable of supplying plenty of hot water. The E-Tec Regular is ideal for homes with two or more bathrooms and properties where low water pressure can occur. If you don’t already have tanks in the loft and a hot water storage cylinder, you might be better off choosing a system boiler that requires a cylinder only or a combi boiler that doesn’t require any additional components.

If you’re thinking about getting a new gas boiler installed, make sure you ask a Gas Safe registered engineer to help you select the right type and size of boiler for your needs before you do anything else.

Is it a High Efficiency Boiler?

It is. The Alpha E-Tec Regular is an A-rated gas-fired boiler with efficiency over 90%, which means it’s one of the most efficient boilers your money can buy. Not only that but this boiler boasts superb build quality and outstanding performance to enhance reliability, improve operating efficiency and prolong the boiler’s lifespan.

Does this Boiler have a Good Range of Controls and Features?

Yep. The Alpha E-Tec Regular has a front panel with buttons and a new backlit display to make it easy for you to use and monitor your boiler. It also has a stainless steel heat exchanger, easy access dry change NTCs and optional external pump wiring. To make life easier for your engineer, the boiler is light enough to be lifted by one person and is easy to install and work with. The E-Tec Regular’s compact dimensions are a plus point too.

How long is the Warranty on this Boiler?

If you purchase the Alpha E-Tec Regular, you’ll have peace of mind that your boiler is covered by a 7-year warranty.
