My family has attended the same church for several generations. It’s a beautiful church with classic stained glass windows, solid wood pews, and seasoned country charm. The families that have passed through the seasoned church have managed to maintain it as best as they could, but there came a time when the boiler needed to be replaced. A committee was formed to select a replacement boiler, and the Heating plus Air Conditioning supplier to do the upgrade and repair. The folks on the committee were gleeful to find a fantastic heating and cooling business located right around the corner from the church. The business presented more than 2 of the choices that needed to be made, making recommendations for each. He said that we needed a boiler that was the right size for the building. As obvious as that sounded, he indicated that in the past, more than 2 boilers were absolutely too large for the buildings they were in. Aside from leading to higher utility bills, a boiler that’s too large for a building can lead to malfunctions. The business also needed to assess the windows, amounts of heat loss, and existing insulation. He wanted to do a regular heat loss analyses to get a better system of the regular boiler to install. The next option he discussed was condensing versus non-condensing boilers. Since most churches have no need to have the building heated at high rapidly adjusting temperatures for the much of the time, he explained that condensing boilers would be the best option, since they’re really energy-efficient. And there was also the option to replace a single boiler with multiple smaller boilers. By having multiple smaller boilers, their heat output can easily match the same BTU requirement as one large boiler – and at higher efficiency.
