The E-Tec

The original E-Tec, which was introduced in 2017, is becoming increasingly popular among installers. The quality, dependability, and ease of installation of the E-build Tec have been critical to its success. It fits easily into a standard kitchen cupboard and has parts accessible from the front for quick and easy maintenance.

With the help of the Grundfos pump and hydroblock assembly, each model has a stainless-steel heat exchanger with wide waterways that ensures the mains water warms up quickly for continuous hot water delivery. A Honeywell gas valve, PCB, and combined condensate and PRV connection are additional important components.

The E-Tec Plus

After being introduced in 2018, the E-Tec Plus gave installers who were already comfortable with the E-Tec boiler another choice. The E-Tec Plus, which is based on the same platform, has the same premium componentry, extra-long flue lengths of 12 metres horizontally and 14 metres vertically, and the popular combined condensate and PRV connection, which can shorten installation time by up to an hour.

The E-Tec Plus is offered in three outputs, including a high-output 38 kW model in addition to the standard 28 and 33 kW models. For homes with high heating and hot water demands, we would suggest the 38 kW model, which is frequently discovered by our installers to be the perfect combi boiler. While maintaining its small size, it also provides a higher flow rate capacity of 15.9 litres of water per minute.

Why buy an Alpha E-Tec boiler?

Alpha E-Tec 28kw Combi Boiler

The Alpha E-Tec line was created so that it would fit practically any home in the UK. It has a 10-year warranty, is wall-mounted, can be used with either a horizontal or vertical flue, and is small in size.

Secondly, they use a stainless steel heat exchanger that costs twice as much but is just as durable as new boilers and has the same 10-year Alpha warranty.

Additionally, every Alpha boiler comes with a free wireless thermostat as standard. However, they do provide a variety of thermostat controls for Alpha boilers, including a smart thermostat with an app to assist you to reduce your energy costs.

Alpha E-Tec & E-Tec Plus Combi Boilers – 28kW, 33kW & 38kW

Alpha logo

The Plus line is one of 5 different E-Tec combi boiler models. With these combination boilers, heating and hot water are provided by the same machine, but if you need some extra power, the Alpha E-Tec 33kw may be a better suit to your home.

They are ideal for small kitchens with limited space because of their compact shape, which may fit in most kitchen cabinets.

No power is sacrificed just because they are small; the opposite is also true. There are three outputs available for the E-Tec combi, so you can find one that will meet your hot water and heating demands.

Alpha E-Tec System Boilers – 20kW, 30kW & 32kW

There are typically a few alternatives, as with any excellent boiler range. The E-Tec system boiler will be ideal for you if your home requires a lot of hot water or if it is a larger home. If you have an old hot water tank, the boiler will still function with it.

These will cost you extra if you don’t have one. Their system boilers come with a 7-year basic warranty, however, certain installation companies may offer warranties of up to 10 years.

Alpha E-Tec Regular Boilers – 15kW, 20kW & 25kW

Both a hot water cylinder and a cold water storage tank are likely to be located in the loft or at a height in your home if your heating system is older. If so, the Alpha E-Tec normal boiler line is perfect for you.

Alpha E-Tec Boiler Prices

We’ve already discussed how affordable the E-Tec series is, so let’s look at how much the boiler itself will cost you.

Keep in mind that the cost of a replacement boiler includes more than just the boiler itself. The costs shown here for replacing a boiler do not include labour.

Alpha E-Tec Boiler Installation

The installation costs of your new Alpha Innovations boiler must be taken into account if you have decided to purchase one. The price of labour will have sole bearing on the cost of boiler installation.

If you already have a combi boiler and wish to replace it with a new one, like the Alpha E-Tec 28Kw combi boiler, the installation costs will be rather modest.

For whatever reason, if you already have a system boiler and decide to switch to a combi boiler, the cost will be higher owing to the additional labour required. Let’s look at some boiler installation costs for Alpha E-Tec boilers.
