"Jeremiah was on time and he tried fixing the leaky toilet first. when that didn't work, he replaced the toilet with a new one (pre-purchased by me) and additionally installed a water bidet that I had purchased eariler as well. He offered to dump the old toilet for a fee which I availed and was overall a positive experience. Looking to hire him to do additional plumbing and furnace related work in the future.

"The installation itself was very good.  I noticed the old tank leaking at 2:00pm Tuesday - was replaced by 2:00pm Wednesday.  They came out quickly to provide a bid and settled on Spengler that night and they were here at 8:30am the next morning.  The installer was friendly and considerate - top notch.  The only knock will be the salesman himself - a bit high pressure not a big deal because we knew we were going to use them after the research we had done.  He was here for nearly 3 hours looking things over then writing his bid then discussing with us his bid then sitting in his truck while we reviewed the bid then finally signing the contract.  The most disappointing was the discussing about their calendar - he wanted to be sure my wife knew which month he was "featured" - really - cmon man!

Install Boiler questions, answered by experts

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.
