"Went great. Maddie H. came by and found the problem with my old water heater. She setup the install for me. Bradley K. installed the new water heater the next day and did an excellent job. Both individuals were very knowledgeable and a pleasure to work with. Great job to everyone concerned. Thanks!"

"Tim did an excellent job installing two new pendant lights in our kitchen. He kept necessary drywall cuts to a minimum, and even cleaned up the drywall dust afterward. The end result was exactly what we wanted, at a very fair price."

"Excellent! This is our 2nd home renovation and remodel with Double Tap HVAC and Electrical. Our first home we utilized Double Tap to ensure the sale of our home by renovating and updating 2 full baths, and all repairs listed per the inspection report. With Double Tap being a licensed contractor, electrician and HVAC it was a total win versus using several companies to complete the job! Outstanding work ethic, affordable pricing, impeccable knowledge base, and consistent daily work to get the job completed on time! We used Double Tap again for our newly purchased home to renovate our entire living space to create an open floor plan. This entailed wall removal, beam / support installation, mold removal, subfloor leveling, attic/ crawl space inspection, floor installation, and a complete staircase reconstruction. Double Tap has also made after hours HVAC emergency service calls for us. I highly recommend Double Tap HVAC and Electrical and will always be a loyal customer recommending to anyone that owns a home or business!"

Install Boiler FAQs, answered by experts

The radiators closest in proximity to the boiler heating system will heat up first. Radiators in rooms farther away from the boiler will take longer to heat up and may be the coolest rooms in the house. The radiator unit itself should heat up evenly; otherwise, there may be trapped air inside it.

Yes. Boilers need water to run without overheating, also known as dry firing. If you run it without a sufficient volume of water, either because of a burst pipe or a leak, you run the risk of damaging your machine or jeopardizing the safety of your home as a whole. When in doubt, shut off your boiler and repair any plumbing issues before turning it back on. Alternatively, consider installing a low-water cutoff (LWCO) before any issues arise. This gadget will protect your boiler by monitoring water levels and automatically shutting it off if it gets too low. 

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

Due to fuel line connections and venting complexity, professional installation is required for safety and efficiency.

To figure out if your boiler is worth repairing or if you need to replace your boiler, first figure out how old the unit is. Boilers last 15 to 20 years, so if your unit is 15 years old or older, it may be better to replace the entire thing depending on the severity of the problems. If it’s not quite that old, then it’s probably worth repairing. Another thing to consider is whether your warranty covers any of the repair costs. If so, it may be worthwhile to repair your boiler to keep it running.
