My family has attended the same church for numerous generations. It’s a beautiful church with classic stained glass windows, solid wood pews, as well as outdated country charm. The families that have passed through the outdated church have managed to maintain it as best as they could, however there came a time when the boiler needed to be replaced. A committee was formed to select a replacement boiler, plus the Heating plus A/C supplier to do the upgrade as well as maintenance. The folks on the committee were glad to find a great heating as well as cooling supplier situated right around the corner from the church. The supplier presented several of the choices that needed to be made, making recommendations for each. He said that both of us needed a boiler that was the right size for the building. As obvious as that sounded, he indicated that in the past, several boilers were truly too big for the buildings they were in. Aside from leading to higher energy bills, a boiler that’s too big for a building can lead to malfunctions. The supplier also needed to assess the windows, amounts of heat loss, as well as existing insulation. He wanted to do a proper heat loss analyses to get a better idea of the proper boiler to install. The next chance he discussed was condensing versus non-condensing boilers. Since most churches have no need to have the building heated at high hot as well as cold temperatures for the much of the time, he explained that condensing boilers would be the best option, since they’re easily energy-efficient. And there was also the chance to replace a single boiler with two smaller boilers. By having two smaller boilers, their heat output can absolutely match the same BTU requirement as one big boiler – as well as at higher efficiency.
