The only way your boiler can be as efficient as you need it to be is if you properly care for it. This means having it professionally installed, repaired, and expertly maintained by experienced technicians who will help it perform at its best.
Another important factor to remember is that even with quality heating services from a company that has been around for over a century like ours, your boiler or any heating system can experience problems from time to time. Eventually, your boiler will wear down to the point that replacement will be imminent.
