Boiler FAQs

Common questions about our boiler services

We recommend annual boiler maintenance, ideally before heating season begins. Annual service ensures safe, efficient operation, catches potential problems early, and can extend your boiler's lifespan by years. Regular maintenance also maintains manufacturer warranty coverage.
We install and service all major boiler brands including Weil-McLain, Burnham, Navien, Viessmann, Buderus, and Lochinvar. We can help you select the right boiler based on your home's heating needs, efficiency goals, and budget.
A well-maintained cast iron boiler can last 25-30 years or more. High-efficiency condensing boilers typically last 15-20 years. Regular annual maintenance is key to maximizing your boiler's lifespan and maintaining efficiency.
High-efficiency condensing boilers can achieve 95%+ AFUE ratings compared to 80-85% for older standard boilers. This means significant fuel savings, especially with today's energy costs. We can assess your current system and provide a payback analysis for an upgrade.
A boiler heats water and distributes it through radiators, baseboard heaters, or radiant floor systems. A furnace heats air and blows it through ductwork. Boilers provide more even, comfortable heat without the drafts and dry air common with forced air systems. Many Connecticut homes were built with boiler systems and benefit from staying with hydronic heat.
Pressure loss usually indicates a leak somewhere in the system, whether at a valve, pipe fitting, or the expansion tank. Sometimes the issue is a faulty pressure relief valve that needs replacement. If you are adding water frequently to maintain pressure, call us to diagnose and fix the leak before it causes damage.
Yes, many boilers can provide both space heating and domestic hot water through an indirect water heater. This setup is very efficient because the boiler heats a separate insulated tank, giving you plenty of hot water without a separate water heater. We install and service these combination systems.
Short cycling is when your boiler turns on and off frequently without running long enough to properly heat your home. Common causes include an oversized boiler, faulty thermostat, low water levels, or problems with the circulator pump. Short cycling wastes fuel and increases wear on components, so it should be addressed promptly.
If radiators are cold at the top but warm at the bottom, air is trapped inside. Use a radiator key or flat screwdriver to open the bleed valve at the top of the radiator. Hold a cloth underneath to catch any water, and close the valve once water flows steadily. If you are bleeding radiators frequently, your system may have a larger issue we can diagnose.
Radiant floor heating is very efficient because it heats from the ground up and operates at lower water temperatures. This pairs especially well with high-efficiency condensing boilers. Floors stay warm, rooms heat evenly, and you can often lower your thermostat a few degrees while staying comfortable. We install radiant systems in new construction and renovations.
