The Worcester Bosch Greenstar 18Ri gas boiler is an incredibly efficient and reliable boiler that is perfect for homes with a low to medium heating and hot water demand. With an efficiency rating of 90.2%, this boiler is designed to help you save money on your energy bills while also reducing your carbon footprint.

    I purchased the Worcester Bosch Greenstar 18Ri back in August, and so far, I’m quite satisfied with my purchase. I’d rate it a solid 4 out of 5. The installation process was pretty straightforward, and the instructions were easy to follow. The boiler works well and heats my home efficiently.

    One thing that I particularly like about the Greenstar 18Ri is its wall placement. It’s sleek and compact, making it a space saver in my small home. The A Energy Class Label is also a plus. I’m glad to know that this boiler is energy-efficient, and I’m not wasting money on unnecessary energy bills.

    I did compare the Greenstar 18Ri to another popular gas boiler, the Vaillant ecoTEC Plus 832. Ultimately, I went with the Greenstar 18Ri because it seemed like a more affordable option without losing out on features. Plus, I’ve had good experiences with Worcester Bosch in the past.

    The purchase and delivery process were pretty seamless. I ordered the boiler online and had it delivered to my home in Fort Worth. It arrived within a few days, and the delivery man helped me carry it to my doorstep. Overall, I’m happy with my purchase and would recommend the Worcester Bosch Greenstar 18Ri to others in the market for a gas boiler.
