Are Alpha boilers any good?

The Alpha range is a wise choice when looking for reliability at an affordable price.

Combi boilers in particular within the Alpha range best suit smaller properties with 1-2 bathrooms. Combi boilers use the mains water supply to heat hot water on demand, eliminating the need to also install a bulky water tank or cylinder.

If you are on a budget, the Alpha E-TEC 33 is a great choice as it offers value for money alongside reliability.

Additionally, with the output being between 33kW, the Alpha E-TEC 33 is able to heat slightly larger homes with up to 15 radiators.

Are there any drawbacks of the Alpha E-TEC 33?

Although there are many advantages to investing in the Alpha E-TEC 33, here are some factors to bear in mind when purchasing.

Meeting high water demand

Because the Alpha E-TEC 33 does not include a water tank it does mean that this combi boiler will struggle to meet a high demand for water. For example, if three people within a household decide to turn on the taps in three different rooms at once, the water pressure will reduce.

Combi breakdowns

If a combi boiler breaks down, you will not be able to access both hot water or central heating at once. Where traditional boilers only power your central heating with a separate boiler for your hot water, the Alpha E-TEC 33 is responsible for powering both your central heating system and your hot water supply.

However, the Alpha E-TEC 33 includes an LCD screen, which means you are notified straight away whenever an issue occurs. You can help to avoid a breakdown because you are aware of and can deal with problems before they get worse in addition to using the manual to fix small problems yourself – saving you costs on repair bills!
