Alpha Evoke Combi Boiler

The Alpha Evoke Combi is a reliable low-cost boiler and the ideal solution for small to medium-sized homes.

Alpha offers a range of reliable budget-friendly boilers to UK homeowners, and the Evoke Combi is no exception. It’s one of Alpha’s smallest boilers and can even fit in a standard kitchen cupboard, making it perfect for apartments and houses with limited storage space.  This compact combi is also a reasonably priced boiler and available in two outputs to suit most small and medium-sized homes.

How Much Does this Boiler Cost?

The Alpha Evoke Combi typically costs between £630 and £690, including VAT. It has an output of 28kW or 33kW and you must make sure you choose the correct size so that it can produce the right amount of heating and hot water for your needs. If you install a boiler that’s too small, it won’t be able to supply enough hot water nor will it heat your home properly. And if you get a boiler that’s too big, not only will you pay more than you need to for a replacement boiler but you’ll spend more money on your energy bills.

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

Alpha’s Evoke Combi is recommended for small to medium-sized homes with one bathroom. If you have two or more bathrooms, this boiler will struggle to run multiple taps, baths and showers at the same time. On the plus side, the Alpha Evoke Combi provides instant hot water on demand without the need for a hot water storage cylinder or tanks in the loft, so it could be perfect for you if you live in a home where space is limited. The boiler is so compact, it can even be installed inside one of your kitchen cupboards.

If you’re not sure about which size or type of boiler is suitable for your home, get the opinion of a trusted Gas Safe registered engineer.

Is it a High Efficiency Boiler?

Yep. The Alpha Evoke Combi has a high-efficiency Grundfos pump and hydroblock assembly, as well as a new stainless steel heat exchanger to help make it cost-effective to run and to also help reduce your energy bills. What’s more, it’s an A-rated boiler, which means it’s one of the most efficient combi boilers on the market. If you buy the Alpha Evoke Combi and you want to improve efficiency and performance, you can purchase a range of optional boiler controls.

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

It certainly has pretty much everything you could want from a low-cost and easy-to-use modern gas boiler. In addition to the stainless steel heat exchanger and Grundfos pump, the Alpha Evoke Combi has a backlit LCD with push-button controls and detailed operational information. It also has a single electrode, IPX4D protection and a one-piece cartridge diverter valve. What’s more, the boiler has a clip-on DHW temperature sensor, dry-change NTCs and a combined condensate and pressure relief valve connection, along with easy access for servicing and frost protection and daily kick pump.

How long is the Warranty on this Boiler?

The Alpha Evoke Combi comes with a 7-year warranty as standard, which is quite good when you consider the cost of this boiler.
