While some homeowners might be capable of successfully installing a central boiler, gas lines typically need to be installed by certified experts, and hiring an expert can save money in the long term. Mistakes made when installing a boiler can waste energy or even damage a home.
Boilers are complex; they handle moving water and gas or oil, and they need to produce well-regulated combustion. While newer boilers often don't function if they're not installed correctly, improperly installed boilers might not be able to detect a gas leak or carbon monoxide buildup. If the system is not vented properly, dangerous chemicals can build in a house. Experts know how to install systems safely, and the cost of installation may be worth it for better efficiency and peace of mind.
