Ratings & Reviews

Rated 5 out of 5 by from Perfect for Cast Iron Radiators Natural gas just became available so we replaced our old cast iron fuel oil boiler. I didn't realize at the time we chose the WM Eco 110 boiler what a great match it was for our old cast iron radiators. Our 1850's two story home has 10 radiators with 109,480 btu output. Once the max/min water temps and outdoor reset parameters were dialed in, the boiler hardly cycles at all. Example, it's 34 degrees outside today and I'm heating my home to 70 degrees with 98 degree water. The boiler runs nearly non stop providing just the right amount of hot water. Amazing! I'm so glad we spent a little more for the Eco 110 modcon boiler over a simple cast iron on/off boiler. Our heating bill is less than half of what it used to be. Partially due to switching to natural gas and the rest is due to the high efficiency Eco boiler. The contractor did a nice job on the installation and gave me enough info (and I read plenty too) to confidently tweak the boiler as needed. With yearly maintenance I hope it lasts a long long time.

Rated 4 out of 5 by from Easy to install and service As a contractor I have installed many brands of wall mounted boilers. I found the ECO to be a very good value, easy to install and available in the three most popular installation sizes for my area.

Rated 4 out of 5 by from Easy to install. Have an issue with the boiler heating water to quickly causing it to trip on very cold days.
