How most big suppliers provide heating is through a boiler system. A sizable boiler system can heat up the entire building, but using a single oil furnace has tons of benefits, then you only have to clean, maintain plus repair the a single system. You save so much money just relying on a boiler system, it lasts almost 4 times as long as any traditional heater. Most heating equipment has a lifespan of 10-15 years, however with a boiler system getting typical service, it can live to be over 50 years old! The boiler doesn’t even need as much service as a oil furnace either. There are less yearly cleaning plus repair tasks for the homeowner to do. This is why big buildings rely on a boiler. It is super self adequate. It can even be used for other functions besides air heating. The boiler can connect to a tepid water tank plus be the water heater, however piping can extend from the boiler plus be hooked up into flooring to create hydronic heating. You can even extend the piping further plus have a heated pool or tepid tub. The piping can even be installed under the driveway. Then the piping heats up the driveway plus no snow will stay on it. The snow melt system will even heat your automobile that is stationary over top of it, however how awesome is that? Most people are against boilers due to their size plus appearance. But, the size comes in handy for all those functions plus the boiler can hide its ugly appearance in your basement easily. Why not use a boiler system?
