"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

In some cases, conversion kits are available, but not all boilers are compatible. Conversion may require significant modifications and should only be performed by a qualified professional. Before making a decision, compare conversion costs to the cost of a complete replacement to determine the most cost-effective and reliable option for your home.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

Coolant and antifreeze are technically not the same thing. The difference between the two is the ratio of water to other chemicals. True antifreeze is mainly made up of either ethylene glycol or propylene glycol, while coolant comprises one part antifreeze and one part water. However, the terms coolant and antifreeze are often used interchangeably, even by pros.

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.
