Alpha E-Tec 25R 25kW Regular Gas Boiler Key Features

1. Compact and Lightweight Design

The E-Tec 25R is designed to fit neatly into small spaces, such as kitchen cupboards or utility rooms. Its compact size allows for easier installation and is particularly convenient in properties where space is at a premium.

2. High-Efficiency Stainless Steel Heat Exchanger

Alpha’s high-grade stainless steel heat exchanger ensures maximum heat transfer, excellent durability, and resistance to corrosion. This component plays a big role in improving the boiler’s energy efficiency and long-term reliability.

3. Easy-to-Use Controls

The user interface is simple and intuitive, with clearly marked controls for temperature and diagnostics. This makes it easy for homeowners to monitor and adjust their heating system without specialist knowledge.

4. Compatible with Standard Heating Systems

As a regular (or heat-only) boiler, the Alpha E-Tec 25R is compatible with traditional systems that include a cold water tank and hot water cylinder. This makes it a perfect replacement for older boiler models without changing the overall setup.

5. Quiet Operation

Engineered to operate with minimal noise, the E-Tec 25R delivers powerful heating without disrupting the comfort of your home environment.

Is Alpha E-Tec 25R 25kW Regular Gas Boiler Suitable for My Home?

The Alpha E-Tec 25R is an excellent choice for medium-sized homes with a traditional open-vent heating system and moderate hot water demand.

It’s ideal if your household uses multiple outlets simultaneously, such as baths, showers, and taps. If your property already has a cold water storage tank in the loft and a separate hot water cylinder, this regular boiler is a straightforward replacement that avoids costly system upgrades.

Additionally, it’s well-suited to households where water pressure might be an issue, as it draws water from the storage tank rather than the mains.

Size

With compact dimensions of just 600mm (H) x 390mm (W) x 305mm (D), the Alpha E-Tec 25R is one of the most space-efficient regular boilers in its class. Its lightweight build also allows for easy wall-mounted installation, making it ideal for smaller homes or where cupboard fit is desired.
